Interview
MR ASHOK JAIN, MD of FUSO Glass
‘Our vision is to be
India’s market leader in
processed glass segment’
FUSO GLASS MD Mr Ashok Jain Speaks To GB
About His Aspirations, Focus Areas & Future Plans
From establishing FUSO as a well-accepted brand in the
Indian and the global markets to becoming the market
leader in the processed glass segment and entering solar
glass and OEM, MD Ashok Jain touches upon a variety of
aspects during this conversation with Glass Bulletin.
Tell us how you entered the glass
business and about your journey with
FUSO Group.
I hail from a glass trading family.
My father and uncles started
the business about six decades
ago. After graduation in 1986, I
pursued CA till I joined business
in 1990. It was the tremendous
encouragement given by my
brothers encouraged me to enter
the glass business.
Those days, it was figured and
sheet glass market. It was a seller’s
market. Demand was multi-fold.
Clear sheet glass supply was in
shortage and tinted glass was a
luxury. Dealers and customers used
to wait in glass factories for their
orders. It was a time manufacturers
and dealers enjoyed good profit.
This prompted me to enter the glass
business, visualizing the industry’s
bright future.
Since 1990, the glass industry
has undergone a tremendous
transition, and I am proud and
lucky to have travelled along with it
ever since.
FUSO has had a remarkable role
to our credit in these transitions.
We introduced in India many
architectural glass products for the
first time. Till we started our first
architectural plant, we had been
importing architectural glasses.
In 1994, we imported heat
strengthened glasses for the first
time in India, for India’s first
IT Park, ITPL, in Whitefield,
Bangalore. In 1996, for the first
time, we imported hi-performance
soft coated DGU glasses, for
India’s second IT Park, Tidel Park,
Chennai. In 1998, we started
selling soft-coated laminated glasses
and we served Infosys alone with
more than one lakh square metres.
By the time we started our first
architectural plant in Chennai in
2004, we had over 100 projects to
our credit in India. In the process,
I had travelled extensively world
over and gained micro and macro
techno-commercial knowledge in
both glass and glass processing
industry.
40 Glass Bulletin | October - December, 2020
FUSO • 2
How did FUSO establish its prominent
position in the industry within such a
short span of time?
It is all team effort. Our team
is working round the clock with
dedication, loyalty and sincerity, in tune
with FUSO’s vision. We have treated
every setback as a stepping stone
and milestone towards success. We
are united in achieving and retaining
leadership. We are united in knowledge
acquisition. This is the secret of our
success.
FUSO is the only company with three
state-of-the-art glass processing
factories in India that are equipped
with all major processing machinery.
Please tell us something about this.
In tune with our vision and to be
nearer to the market, strategically we
opted for plants in different locations
— Chennai, Hyderabad and Mumbai.
It’s true FUSO today has the largest
processing capacity in the country and
most importantly, FUSO family’s vision
to go all out with all the processing
facilities viz., tempering, insulating,
laminating, screen printing, heat soak
etc., at one go in all our plants. This
has, in fact, built our strength from Day
One of our plant operation.
In fact when FUSO was
constructing its first plant in Chennai,
I happened to meet one of the veterans
of that time in the industry who asked
me, “Are you sure you want to put up
all these lines at one go without having
any experience in glass processing
industry?”
It was shocking for a second. But
FUSO took it as a challenge and just
in two years, i.e. in 2006, we saw that
we were right in our vision. We found
tremendous market acceptance, which
paved way for our further expansion in
Hyderabad and Mumbai.
You recently invested a lot on
upgrading your facilities with world
class machinery. Few of them are even
the first in India. Share with us your
thoughts behind this.
The purpose behind our investment
in upgrading our facilities is to be the
market leader. Many of our machineries
are world-class and first in India.
We have a strong technical advisory
committee, which is monitoring
global techniques and performance
parameter criteria. Healthy periodical
debates are undertaken and decisions
taken for upgrading and modification.
FUSO was awarded the Best Glass
Processor Award – National, for thee
continuous years since 2017.
What facilities do you have in your
factories to test the quality of
processed glass?
FUSO’s plants are equipped with wellestablished
and fully equipped state-ofthe-art
glass testing facilities. We adopt
uniform processing techniques and

The Quality Standards Fuso offers:

irrespective of the source of supply.
In FUSO, we follow global standards.
FUSO holds certificates viz., ISO 9001-
2015, QNL, BIS/ISI, IGCC (soon),
ARAI etc. Our Plants are accredited
and certified by Saint Gobain to
process their hi-performance coated
glasses. FUSO was the QNL (Qualified
Network of Laminator) certification by
Kuraray (globally renowned lamination
interlayer manufacturer) which is
issued to competent glass processors
globally.

Interview
What makes FUSO India’s largest
glass processing company?
Customers support – every increasing
customers and their appreciation,
guidance and support are the very
reasons behind our growth year
on year. FUSO reciprocates our
customers’ confidence, with our largest
glass processing facility.
Having every type of glass
processing facility under one roof is
another strong factor.
What is the importance of safety
standard in your view? How are your
factories equipped in this regard?
We care for our human assets first.
Glass is heavy, fragile and dangerous to
handle without proper safety standards
and equipment in place.
In our Chennai plant, we have 6
EOT Cranes covering the entire factory
floor area. In all our plants, loading and
unloading in seaming, double edger
line, insulating line, laminating line
etc., are automated — first of its kind
in the country. All our glass handling
systems are fully mechanized.
We don’t compromise in safety
standards. COVID-19 has made us
much more cautious about the health
of our employees. Periodical training
and monitoring safety measures are
part of our routine operative system.
In short, we minimize people’s direct
contact with glass.
“
FUSO is entering the OEM
segment in a very big way.
We will have our first OEM
plant in Chennai, followed
by another in the west.
In the next five years,
we will be investing in two
plants for OEM segment,
two for architectural at
new strategic locations and
a solar glass plant.
FUSO’s PROCESSING CAPACITY:
Process
Production
Lines
How did FUSO establish itself as a
big name in the export of processed
glass?
With two factories located strategically
in port cities of Chennai and Mumbai,
we are able to serve the global market
effectively. We have all standards,
certificates and facilities to meet global
expectations. Our team is strong to
understand and meet the technocommercial
requirements of our
international customers.
Our first mega break was with
the execution of 40,000 sq m Vision
Exchange Project in Singapore. This
gave us confidence to cater to the
global demand, and presently, we are
involved in projects in Singapore,
Malaysia, Australia, New Zealand,
Colombo, Dubai, Qatar, Africa,
Bangladesh, Europe etc.
Now-a-days, float glasses of many
international brands are available
in India to suit the choice of global
customers. Best process quality of
international standards are available
with FUSO. All these factors give
momentum to our export business.
You have family members in your
business. What role did this aspect
play in the journey of FUSO?
Our joint family is our biggest strength.
Each family member has a specific
strength in one or few particular fields.
Our head of the family and my
uncle, Tarachandji, is our group
chairman. My brothers Mr C L Jain is
a great visionary and controls corporate
finance and Mr Madanlal is an expert
in admin, legal matters and taxation.
Our director, Mr R K Chouhan, excels
in operations. My younger brother,

programme. Jainik Jain is successfully
heading FUSO’s new vertical - entry
into OEM and locomotive segments.
All major decisions are taken
by the Board of Directors. Going
forward, FUSO wants to transform
professionally.
What changes have you seen in
the glass processing industry and
how did this lead to the necessary
transformation?
Glass processing industry has
undergone tremendous changes in last
two decades in many ways.
99
If you look at the processed
glass size, it has moved from
semi-jumbo to jumbo, facade
has started demanding floor to
floor glass panels, shop-fronts
have started asking for single
panel of double floor height.
99
It has moved from normal
processing to more of

structurally designed glass to
take care of wind-loads velocity
and becoming a substitute to
walls.
99
Glass being the aesthetic
element in the building, facade
consultant and end-clients are
keen on processing parameters
viz., roller waves, bow/warp,
and edge dip these days.
To accommodate these customer
expectations, glass processing industry
has transformed by up-grading plant
machinery and technology from time
to time.
What are your thoughts on
innovation in the glass industry in
the present day?
Customers are contemplating to use
glass for more and more applications
such as cook-tops, bullet proof
vehicles, fire-protection areas, privacy
cubicles and so on. From lighting to
home appliances, from facades to
locomotives and from ship to mining
equipment, processed glasses are
taking substantial presence.
Customers are foreseeing more and
more advantages in using glass and
hence, innovations in glass processing
is ever increasing. FUSO is gearing up
to accommodate new innovations with
ease.
What is your primary focus for FUSO
in India?
Branding — making FUSO a wellaccepted
brand in the Indian market.
Making this brand recognition possible
by delivering value for money, to
its customers with consistency in
maintaining global glass process
standards. FUSO also aims to place
brand Fuso as the well-sought ‘Makein-India’
product, globally.
What is your vision for FUSO for the
upcoming years?
Our vision is to be India’s market
leader in the processed glass segment.
We have been contemplating on the
next step of FUSO. We will soon enter
all segments of glass processing. In
fact, we are entering in a very big way
in OEM segment. We will have our
first OEM plant in Chennai followed by
another in the west.
Fuso will also enter into solar glass
manufacturing. We are already into
architectural, automotive, locomotive
and interior segments with remarkable
presence.
In the next five years, we will
be investing in two plants for OEM
segment, two in architectural at new
strategic locations and a solar glass
plant.
FUSO will stay in the glass business
only and invest accordingly. Thanks
to our government, our customers,
dedicated team and Board of Directors,
we are moving ahead in our successful
business journey.

a new segment that will be part of the
exhibition – fenestrationpro INDIA.
The moderators expressed hopes
that although the country and
the industry were going through
a difficult time because of the
pandemic, the worst was over. The
glass industry will bounce back in no
time aided by collective efforts of all
those associated with it and supported
by the government’s initiatives and
policies, Mr Nair said.

panellists presenting their opening
remarks. They opined that the
coming year would be big for the
industry and projected tremendous
growth of the glass sector.
ANAND NAIR
Mr Pundhir spoke about
customers’ requirements in the
present day. He said aesthetics and
performance of glass are the two
aspects customers were looking for
Energy efficiency is talked about a lot.
Mr Pundhir added that the customer
was aware about sustainability and
green buildings because there is so
much information available to them.
He said that the Union government
has regulations for high performance
glass at par with developed countries.
The industry can greatly benefit
by adopting these provisions and
educating itself, Mr Pundhir added.
Speaking on profit margins,
Mr Pundhir said per capita
consumption of glass in India has to

we can learn new things, he said,
adding there is a lot of innovation
in this field and it has a great future
ahead.
Adding to this, Mr Madan said
there is a huge market for export
of designer glass products made in
India. Awareness should be created
about this segment in the market, he
added.
Mr Bagkar focussed on quality as
one of the most important aspects to
be considered. Processors should be
quality-conscious besides being price-

Speaking on how the government’s
‘Make in India’ was gaining traction
in the industry, Mr Bhavesh said
small equipment for glass is being

unlike in the past when everything
had to be imported. He said this trend
will slowly grow, and with focus on
quality and also availability, the glass
industry in the country can become
independent.
Mr Pawar said this is undoubtedly
the right time to invest in the glass
industry in India. He said that 60-70
per cent glass for the home appliance
sector is imported. With emphasis on
value addition in glass in this sector,
the domestic market can be easily
captured, Mr Pawar added.
He said the demand for domestic
producers will double itself in
the next two years if investments
are made and expansion plans
undertaken now. Mr Pawar stressed
on the need to think about cutting
operational costs which will definitely
lead to increase in profit margins.
The webinar also conducted an

Glass Bulletin | October - December, 2020 49
Event
Ready for Re-Start: Messe Düsseldorf
draws up Hygiene and Infection
Protection Concept
We Offer All Prerequisites For Safe And Successful Trade Fairs In The Times
Of Coronavirus: CEO Diener
Here we go again: CARAVAN SALON Düsseldorf, the world’s leading trade fair for
motorhomes and caravans, marked the resumption of trade fair operations at the
homebase in Düsseldorf from September 4 to 13, 2020.
After the lockdown in spring
it has been possible to hold
trade fairs and congresses
again subject to specific conditions
in North Rhine-Westphalia since 31
May 2020. Other Düsseldorf events
on the agenda for this year include
the medical technology trade fairs
MEDICA and COMPAMED (16 –
19/11), the industrial fittings event
VALVE WORLD EXPO (1 – 3/12)
as well as the trade fair duo for
wire, cable, pipes and tubes, wire
and Tube (7 – 11/12).
The hygiene and infection
protection concept of the
Düsseldorf exhibition centre
enables relevant industry platforms
to be held while ensuring the
greatest protection possible for
exhibitors, visitors, partners and
members of staff.
It ensures observance of the
required health precautions,
hygiene measures and distancing
rules and encompasses both
measures for headcount and space
management as well as hygiene,
technical and organisational
measures provided by the federal
state government for holding
congresses and trade fairs.
The current Corona Protection
Ordinance of the federal state of
North Rhine-Westphalia serves as
a basis.
At the same time, the gradual
easing of international travel
restrictions promotes the
resumption of trade fair operations.
Following the first border openings
within Europe, the German Federal
Government has gradually lifted
the restrictions for entries from
third countries since 1 July 2020.
Such initiatives especially benefit
Düsseldorf’s leading international
trade fairs as they stand out with
their particularly high international
attendance. In 2019 this stood at
73.4% for exhibitors and 37.1% for
visitors.
Significant Step for Business
“I welcome how responsibly
Messe Düsseldorf deals with the
topic of infection protection and
takes all precautions to ensure
that safe trade fair operations are
also possible in Corona times,”
emphasises Thomas Geisel, Lord
Mayor of the state capital and
chairman of the supervisory board
of Messe Düsseldorf.
“With its concept the trade fair
company provides the basis for
the re-start that business needs so
urgently. Its global No. 1 trade fairs
are indispensable for this; and this
not only applies to exhibitors and
visitors from throughout the world
but also to the numerous firms
operating in skilled crafts, stand
construction, transport, catering,
hospitality and retail that all benefit
from the events,” he adds.
According to a study by Munichbased
ifo Institute, Düsseldorf’s
trade fair and congress operations
induce annual sales of approx.
EUR 2.98 billion across Germany
(in Düsseldorf: EUR 1.66 billion),
secure 27,692 jobs (in Düsseldorf:
16,664) and generate additional
tax revenue of EUR 567 million (in
Düsseldorf: EUR 36.3). One third
of all overnight stays at hotels are
accounted for by trade fairs.
Emphasising on the special
relevance for the exhibiting
industries, Wolfram N. Diener,
CEO of Messe Düsseldorf, says:
“All signs are pointing towards
a new departure. Enterprises
need platforms now to present
themselves and their innovations,
to network and jointly chart
the course for the future. With
our leading international trade
fairs, we deliver second-to-none
prerequisites for doing so. Our
hygiene and infection protection
standards ensure that the safety
and health of our exhibitors,
visitors, partners and members
of staff are protected in the best
possible way. We are ready.”
Detailed Concept based on Proven
Measures
As a matter of principle, the
official distancing and hygiene
rules shall be applicable at events
held at the Düsseldorf exhibition
centre, compliance is also up to
each individual – as is the case in
the public sphere and in retail.
These rules include maintaining
a minimum distance of 1.5 m,
seeing to one’s own hand hygiene,
50 Glass Bulletin | October - December, 2020

wearing a face mask, following the
sneeze etiquette and foregoing
such welcoming rituals as shaking
hands. If needed face masks will be
handed out by service staff at the
entrances and at the premises.
All forthcoming events at the
Düsseldorf location will be subject
to a limitation on persons present
to ensure minimum distancing
can be observed. Tickets will
therefore be limited and only
available online; visitors will have
to register upon purchasing them.
This permits the monitoring of
headcount as people enter the
venue. At the same time, the
provisions of the Corona Protection
Ordinance of the federal state
North Rhine-Westphalia governing
the traceability of all persons
present can be complied with and
implemented.
Concrete Measures during Trade
Fair Operations
Wherever queues form, floor
markings will draw attention to the
minimum distancing requirements.
Here and on all public spaces,
Messe Düsseldorf staff and security
personnel will ensure these
distances are observed. This is
performed on site and by means of
existing video systems.
At the exhibitors’ stands this is
done by their employees. To avoid
bumping into people all aisles are
to be used as in road traffic i.e. by
keeping to the “right-hand lane”.
All doors – with the exception of
fire protection doors – will be wide
open for contactless use.
Sanitizers will be made available
across the entire premises; at
stands exhibitors themselves will
be in charge of this. All payment
transactions will be cashless –
to the extent possible. For this
reason all ticket counters will
remain closed. Service desks,
counters, etc. will be equipped with
transparent partitions as hygiene
guards. At least twice a day – also
more frequently depending on
the footfall – turnstiles and ticket
scanners, service desk and counter
tops as well as contact surfaces
such as door handles etc. will be
cleaned.
In the toilet facilities, the
maximum number of persons is
determined by the number of open
WCs and urinals. Here one out of
two urinals and wash basins will be
blocked off; WC cubicles will all be
accessible without any restrictions.
To monitor the number of users
and safeguard the shorter cleaning
and disinfection intervals of WCs,
handles, washbasins and taps
all toilet facilities will be staffed
permanently by cleaners.
Constant and sufficient
ventilation is ensured – by
the air-handling systems and
the specifications for stand
construction and exhibit displays:
the volume of fresh air constantly
supplied to the halls exceeds the
actual need many times over and
the fresh air quality corresponds to
the outdoor air.
Furthermore, conference rooms
or ground floors in multi-storey
stands are only permitted with
open layouts to ensure they receive
sufficient ventilation. The same
applies to walk-in exhibits whose
doors, windows and roof hatches
have to be open at all times.
As before, there will be food
service and catering offered at the
events. The operators have to draw
up their own hygiene and infection
protection concept for this based on
the Corona Protection Ordinance
of the federal state of NRW and its
annexes.
For the duration of the Corona
pandemic there is a general ban
on stand parties and/or exhibitor
parties at the premises. Stand
construction is governed by the
“SARS-CoV-2-Arbeitsschutzstandard”
H&S standard of the
Federal German Ministry for
Labour and Social Affairs.
Safety for the Workforce of Messe
Düsseldorf
The protection of the workforce
is also guaranteed: all members
of staff will receive textile face
masks; for outdoor jobs there will
be an additional visor. Tools are,
if possible, personally assigned to
individual employees – and will be
cleaned before being handed over
to third parties. Protective gloves
are mandatory if jobs cannot be
performed with personally assigned
tools or if an immediate exchange
of materials and objects is required.
The hygiene and infection
protection standards are constantly
adapted to future developments
and changing legal requirements.
Messe Düsseldorf will provide
timely information on any changes.
Wolfram N. Diener emphasises:
“The safety of our exhibitors,
visitors, partners and employees is
always our top priority. As usual,
they can expect a high level of
hygiene, safety and good medical
care at the Düsseldorf exhibition
centre”.
About Messe Düsseldorf Group
With revenue of EUR 378.5 million in 2019,
Messe Düsseldorf Group has maintained its
position as one of Germany’s most successful
trade fair companies. As many as 29,222
exhibitors presented their products to 1.4
million trade visitors at events in Düsseldorf
in 2019. Düsseldorf Exhibition Centre hosts
around 40 trade fairs in five sectors of
expertise: machinery, plants and equipment;
the retail trade, trades and services; medicine

Product Hunt
Strato Bird Friendly: First anti-collision
EVA film to protect birds
Designed By Satinal In Italy, It Is Based On Studies Carried Out By
International Associations, Labs
Satinal produces in Italy the first anti-collision EVA film for bird-friendly applications, thanks
to the development of its own exclusive extrusion technology.
Strato Bird Friendly is the first
innovative and unique EVA
interlayer on the market: it makes
it possible to obtain a laminated safety
glass characterized by lines, dots or
patterns, recognizable by birds that,
consequently, will avoid colliding
against the glass.
Satinal has created the design of
these effective patterns in its R&D
Laboratory, based on studies carried
out by international associations and
laboratories that have been analysing
the flight and behaviour of birds
for several years. Some tests have
shown that birds avoid flying through
horizontal spaces less than 2″ (5 cm)
high or through vertical spaces 4″ (10
cm) wide or less.
These guidelines are commonly
known as the “2×4 rule”, but actually
there are exceptions resulting from
research conducted on specific species.
This new range of EVA interlayers,
has been designed by Satinal with the
aim to raise awareness of designers,
glaziers, architects etc. by encouraging
them to use the right tools to reduce
the problem.
Laminated glass with Strato Bird
Friendly EVA interlayers will not
only limit bird collisions, but will also
provide several advantages:
;;
Benefit 100% of the advantages
given by laminated safety glass
with EVA film
;;
Buy the quantity needed for a
specific project (no minimum
order quantity)
;;
Any customised size available at
no extra cost
;;
Incredible cost savings
production using standard float
glass for lamination
;;
Avoid expensive stocks of big
quantities of non-standard float
glass
;;
Customize the EVA film with
the pattern requested by the
designer or architects
;;
Combine the Bird Friendly line
with other Strato products to
create glasses with additional
benefits (e.g. solar control)
;;
High visible light transmission
;;
High weather resistance due to
the properties of Strato EVA film
;;
Visual continuum (selected
patterns do not disturb the
view)
;;
Full protection against UV rays
There are many factors that
affect the selection of a product that
makes glass bird safe: by choosing an
interlayer from the Strato Bird Friendly
collection to laminate the glass, its
transparency and reflection can be
reduced.
Birds do not recognize glass as an
obstacle because it is a transparent and
reflective material.
Transparency, sometimes, can be
a problem even for man: in fact, it
happens not to notice the presence of
a door or a glass wall. However, man
is able to recognize details such as
handles, uprights and fixtures, thus
avoiding collision.
Unfortunately, birds do not have this
kind of perception and they are also
attracted by plants, food, water etc.
placed inside or outside the rooms that
they see through glass.
Another aspect, in addition to
transparency, is the reflection of light:
depending on how and where the glass
element is positioned – for example in
relation to the sun, the surrounding
environment, internal light levels etc.
– it can look like a dark passage that
birds might mistakenly see as a usual
space between branches and leaves.
Moreover, glass can act as a mirror:
reflecting the sky, clouds or vegetation
around buildings, it attracts birds and
this effect is the most frequent trigger
of the impact.
With Strato Bird Friendly you can
get a product created by humans but
designed for nature, without sacrificing
its aesthetic appeal.

to achieve our ambitious goals in the
world of ‘new normal’ – where nothing
will ever be the same again, neither
economically nor socially. We are also
excited about completing the merger
process that started at the beginning
of this year with the purpose of
consolidating all our business activities
under a single entity to boost our
global competitive edge in line with
our long-term strategies.”
“Currently, our only company
trading on Borsa Istanbul (Istanbul

Introducing ‘Better Home’
‘India’s First And Only Hyper Local App For Home Improvement Services
And Products’
‘Better Home’ connects dealers of glass, mirror, plywood, hardware, facade materials and
similar products with buyers near their locations, just like foodtech platforms Swiggy or
Zomato.
Here’s a solution to connect
dealers of glass and mirror
with customers near their
stores. The founders of ‘Better Home’
have brought a platform to sell home
improvement products (building or
construction materials) and services
online and get unlimited leads too.
When a buyer needs customised
products or solutions (like changing
their kitchen splash-back to glass),
‘Better Home’ lets them book
enquiries directly with the store
providing the required details. Dealers
will confirm an appointment with the
buyer, visit the home/office, provide
consultation, use the app to place the
order and get paid.
A dealer in Delhi can also service
an architect customer in Bangalore
using the premium dealers in the
app, ensuring good service. “As the
app is designed to get leads directly
from the customers, the conversion
ratio will be 300% higher compared
to portals like India Mart or Just
Dial. Dealers will get unlimited
leads. Further, if enquiries come to
the app, we will assign to premium
dealers in that locality,” says ‘Better
Home’ co-founder and CEO Balaji
Kalyansundaram.
Kalyansundaram founded the
company with Karunakaran S L, who
holds the position of CTO.
Kalyansundaram’s father was one
of the leading mirror manufacturers
in south India, and the CEO is glad
to be associated with glass and mirror
dealers in the digital age through the
app, which was born out of 40 years of
glass business experience and 20 years
of global IT experience.
“With over 5,400 glass dealers
and 65,000 dealers from all the 25
categories (across India) in the app,
we are launching the buyer app for
Diwali,” he said.
Kalyansundaram says his mission is
to enable local businesses serve their
customers with convenience and safety
online. The values of the company are
“Customer Obsession, Ownership, and
Continuous Improvement.”

PVB interlayer, which is designed
to produce one of the most color
neutral, brilliant laminated lowiron
glass products available today:
Guardian UltraClear® LamiGlass
Neutral.
“Until now, laminating low-iron
glass was challenging because
traditional interlayers tend to reduce
the neutral, transparent properties
of low-iron glass,” says Priya Kalsi,
segment market manager with
Eastman.
“Our new Saflex Crystal Clear
interlayer dramatically enhances the
aesthetic appearance of Guardian
UltraClear® low-iron glass when
laminated, offering exceptional crisp
neutrality and beauty, providing
aesthetics that are very similar to
monolithic Guardian UltraClear
glass. All the traditional benefits of
laminated glass remain unchanged,
including safety, security and
acoustic control. Saflex Crystal Clear
PVB interlayer remains virtually
undetectable at any visible angle in
any light,” Kalsi adds.
“This collaboration with
Eastman answered a key concern
for both companies’ customers
in search for an endless need for
neutrality and transparency,” says
Eric Lassalle, product manager
Laminated Glass at Guardian Glass.
“Our joint cooperation enabled
us to deliver a greatly improved
aesthetic appearance when Guardian
UltraClear glass is laminated with
Saflex Crystal Clear PVB interlayer.
Crystal Clear PVB can also be used
with various combinations of coatings
and surface treatments on Guardian
UltraClear glass, making it ideal for a
targeted range of high-performance
solutions.”
Applications
Guardian UltraClear LamiGlass
Neutral can be used in a wide
range of applications where brilliant
neutrality, high transparency and
safety are required. These include:
Interior: Interior Doors /
Partitions / Balustrades / Stairs and
Railings / Furniture / Retail Shelving
/ Display Cases / Museum Glazing.
Exterior: Cladding / Curtain
Walls / Facades / Windows / Skylights
/ Exterior Doors / Storefront and

Permasteelisa Group
completes facade
of One Vanderbilt in
New York City
Tower Offers Unparalleled Package Of Amenities,
Innovative Design, Sustainability Practices
The Permasteelisa Group, a world leader in the “curtain
wall” industry, has completed the architectural envelope of
the new One Vanderbilt, the iconic tower inaugurated on
September 14 in New York.
64 Glass Bulletin | October - December, 2020
Permasteelisa Group • 2
The ribbon cutting ceremony
was held on September
14 for One Vanderbilt,
the new 427-metre-high (1401
ft) skyscraper that redefines the
Manhattan skyline and constitutes an
important milestone in the ongoing
modernization project involving the
Midtown East area.
One Vanderbilt is the second tallest
office tower in New York, the tallest in
Midtown and one of New York’s most
sustainable office towers. Owned and
developed by SL Green, the iconic
building designed by Kohn Pedersen
Fox (KPF) Associates features four
interlocking and tapering planes that
spiral toward the sky.
With a size of 160,000 square
metres (1.7 million sq ft), the
building offers an unparalleled
package of amenities, innovative
office design, technology offerings,
best-in-class sustainability practices
and a prime location at the doorstep
of Grand Central Terminal.
An extremely advanced facade
The project has been performed
by Permasteelisa Group through
its subsidiary Permasteelisa North
America, based in Windsor (CT),
with the support of other competence
centres spread around the world in
Europe and Asia.
The group has designed, engineered
and produced 8,743 curtain
wall panels, with 1,060 different
configurations for a total of around
70,000 square metres (753,500 sq ft) of
curtain wall. This includes 660 corner
panels that were all different from each
other as the tower is tapering from the
bottom to the top, resulting in several
unique panel modulations.
In particular, this façade is
characterized by two main typical
panels. The vision panels, which are
used at the typical office space unit, are
equipped with very tall glass that reach
almost 6.7 m (22 ft) on the executive
floors, and a ventilated spandrel panel
cladded by terracotta tiles. There are
Glass Bulletin | October - December, 2020 65
Project Hunt
34,845 extruded terracotta tiles, with
a very specific concave shape and
finishing that reflects most of the sun
beams during the day, creating amazing
reflections.
In addition, a special solution was
developed for the mechanical floor
units, which are equipped with a
unique three IGU faces, of which one
is recessed from the others in order to
allow for natural ventilation.
This huge project required big
efforts by our organization and the
project team to manage such a large
scale and huge operations broken
down in many offices and vendors.
Thanks to the group’s DNA to operate
as a Transnational Global Enterprise,
the workflow has been steady for
almost two years of production and
installation, allowing us to achieve a
great on schedule completion.
Sustainability
Permasteelisa has always stood out for
its commitment to eco-sustainability:
the use of sustainable materials and
processes, as well as the constant
commitment to the development of
solutions capable of guaranteeing
energy savings, contribute to protecting
the environment, making more liveable
buildings and, finally, to improve the
quality of the world in which we live.
One Vanderbilt was designed to achieve
the highest level of LEED certification
and, in its path, even went beyond what
is required to achieve this status.
One Vanderbilt is also designed to
obtain a WELL certification, which is
awarded to buildings that maintain and
improve the health and well-being of
their users.
One Vanderbilt is, in chronological
order, the latest ‘supertall’
building successfully completed by
Permasteelisa Group, thanks to the
collaboration of all the players involved.
The ‘supertall’ category (> 300 m)
includes projects such as the Hong
Kong International Commerce Center,
the Lakhta Center in St. Petersburg or
the Central Park Tower in the New York
City, now nearing completion.
About Permasteelisa Group
The Permasteelisa Group operates worldwide
in the design, production and installation
of architectural enclosures, curtain walls
and interior systems, placing itself in a
position of absolute leadership in the global
reference market. In all of its projects the
group contributes with its know-how and its
experience, especially for the “Special Features
Buildings”, from the design phase to the
successful completion, reaching the architectural
expectations of its customers.

More daylight for good health
It Plays Important Role In Our Well-Being, Must Be Factored Into Design Of
Hospitals
As a modern society, we’re spending about 90 per cent of our time indoors – at home, in
offices or commuting. How is it possible to get access to daylight, when we can’t naturally
be outside? The solution lies in making buildings more transparent.
Sustainable buildings offer a
combination of economic,
environmental and social
benefits. And daylighting is an
essential element of sustainable
building design because of its proven
benefits for well-being and a healthy
society.
Turning back to daylight
Some European countries have
already addressed the daylight issue by
adding minimal glazing requirements
to their construction regulations. The
recommended optimum is around 30
per cent, depending on the climate
zone.
Glazed surfaces in buildings provide
occupants with natural light and
a visual connection to the outdoor
environment. Research shows that
daylighting improves people’s comfort,
sense of well-being, and even mental
and physical health. That’s why
architects are now designing buildings
with optimised daylight, along with
minimized energy requirements for
heating and cooling.
Dose of daylight for patients
Because daylight plays such an
important role in our well-being, it
must be factored into the design of
healthcare buildings and hospitals.
The founder of modern nursing,
Florence Nightingale, recognized the
importance of natural light in healing.
Her 1859 notes state: “Direct sunlight,
not only daylight, is necessary for
a speedy recovery. While we can
generate warmth, we cannot generate
daylight or the curing effect of the
sun’s rays.”
Although this old wisdom was
eclipsed for a time by the advances
in technology and modern medical
Kaari Hospital, Kuopio public area Partanen & Lamusuo Ltd, photo ©KariMattiAntero Puustinen
treatment, the tide is turning. Today,
numerous new studies demonstrate
that access to daylight reduces the
average length of hospital stay, speeds
post-operative recovery, lowers
requirements for pain relief, provides
quicker recovery from depressive
illnesses and even has disinfectant
qualities.
Case: Kaari Hospital in Finland
Kaari Hospital, a new extension
of the Kuopio University Hospital
(KUH) in central Finland, exemplifies
progressive daylighting strategies
realized in a most creative and
artistic way. Opened in May 2015,
Kaari Hospital specializes in surgery,
maternity services and intensive care.
Two architect firms partnered in the
project. Lukkaroinen Architects Ltd
had the lead role for the overall design
concept, as well as the clinical and
operating rooms, which are a specialty
of the firm.
Partanen & Lamusuo Ltd took
part in the overall design concept
and was responsible for the interior
design, covering all public spaces.
The firm had worked on the design
for the main hospital hall earlier, so
they were chosen again to keep the
same style for the new building. Most
importantly, the firm designed the
special Evolution façade, a unique
art piece that has made the hospital a
landmark.
Inviting natural light in
For both teams, daylighting guided the
design for this new building to offset
the long, dark days of winter in central

Finland. The resulting spaces invite as
much natural light in as possible. The
basic elements for the new unit were
clear colors, shapes and motifs from
the natural world, bright spaces and
– most importantly – large windows to
the world outside.
“Daylight plays an important role
in an environment that supports
recovery,” says Chief Designer Pekka
Lukkaroinen. “We brought in as much
daylight as possible into the clinical
spaces by designing two atriums with
high ceilings at the centre of the
hospital complex. We added skylights
to the staff facilities, commonly located
in the middle part of a hospital, which
also need natural light.”
Chief Designer Heikki Lamusuo
adds: “The building itself is very large.
To bring in light to the hospital, we
created a 7-meter-wide inner street,
running north-south and featuring tall
open windows that allow daylight to
flood in.”

using digital ceramic printing on
glass, the surface area of Evolution is
around 1,500 m² and is composed of
476 glass elements. The printed glass
for this masterpiece was produced
by Finland-based Rakla, a long-time
user of Glaston’s glass processing
technology.
Chief Designer Jaana Partanen
explains the inspiration: “We wanted
to show something inside the body.
When reviewing pictures, we saw the
countless small elements familiar to
doctors and researchers that can’t
be seen without a microscope – and
blew them up. The colors are the
same as the dyes doctors use to see
the internal elements better, like cells,
tissue structures or magnetic brain
images.”
Depending on the time of day and
season of the year, the artwork helps
filter the amount of sunlight. Some
parts of the image are more opaque
while others are almost transparent.
“We’re very content with all
public lobbies, but most proud of
the Evolution artwork. It’s working
well, and we’re very satisfied with the
results. For the hospital, Evolution has
become their brand, and it connects
very well with the people who see
it. Usually, people go to a hospital
because there’s something wrong – we
want everyone to celebrate the beauty
of the human interior,” she explains.
Balancing transparency and color
depth
“At the time, this was the first big digital
printed art façade made in Finland.
And we are still the only Finnish
supplier with suitable digital print
technology,” Pertti Lukkari, CEO of
Rakla, explains.
Finding the right color and depth
was challenging because of the ceramic
colors. Once melted, ceramic paint
becomes a permanent part of the glass
during the tempering process. So,
digital printing is actually like working
in three dimensions with transparency.
“It’s easy to be proud of this hospital
façade, because you get a true ‘wow’
feeling when viewing. The complexity
came from trying to convert the
artist’s idea into a functional solution
that meets all the safety and façade
construction requirements,” he
continues.
Energy-efficient microclimate
The main façade is actually a double
façade, which creates its own
microclimate by protecting the building
from the summer heat and excess
light. The outer façade is the printed
glass sheet; the inner façade is normal
concrete with conventional windows.
This unique combination eliminates
the need for any cooling system and
was cheaper to build. It is energy
efficient, reducing the sun and extreme
seasonal climate change impacts.
Goodness through glazing
Modern glazing can now achieve
very high levels of durability, safety
and energy efficiency. Using the
transparency properties of glazing is
perhaps the easiest way to bring the
goodness of natural daylight back into
our lives.

HEGLA app: Closes digitalisation gaps,
improves processes
Documents, Maintenance Info Filed In App Can Be Accessed Via
Smartphone, Tablet Or AR Headset
The glass production of the future will be fully networked and digitalized. Alongside digital
support for employees, it will provide quick insight into machine capacity and even the
current position of a specific pane. Thanks to central databases and open interfaces, many
of these concepts would be possible today, but they are not easy to realise in practice.
The Shop-Floor Assistant app was designed to be a stand-alone, manufacturer-independent system. Depending on the configuration, access to data is possible
from any location at any time.
Often, different production areas,
software and systems from a
variety of manufacturers must
be combined into one digital concept.
With the Shop-Floor Assistant app,
HEGLA New Technology has closed
these gaps, providing operating
personnel with key information and
helping to reduce process times.
“To a great extent, productivity
depends on machine performance
and the way they are embedded in
the production chain,” emphasised
Dr Markus Schoisswohl, Managing
Director of HEGLA New Technology.
“Beyond that, sideline activities often
have a significant impact on the overall
process – and such activities can often
be simplified and accelerated by means
of digital tools.” Schoisswohl said.
Searching for racks, transporting
them, fetching tools, gathering
documents and organising
maintenance and service work are
all typical tasks that can slow down
production. “We asked ourselves how
we can support glass processors with
such tasks using simple digital means –
irrespective of the manufacturer,” said
Schoisswohl. The answer: Shop-Floor
Assistant in smartphone and tablet
versions.
Support for maintenance and service
The “Maintenance” section of Shop-
Floor Assistant offers comprehensive
options for simplifying and centralising
maintenance and service tasks.
Whether it’s a glass machine,

The app’s various functions map sub-sections and functions
of the value chain, simplify processes, structure workflows,
and make it possible to request the further transport of a piece
of glass, report breakage, identify a pane, determine a rack
position, organise maintenance process, and more.
stacker, roll-up gate, or indoor crane,
all documents and maintenance
jobs can be filed in the app, which
reduces handling time and means the
information is available anywhere via
smartphone, tablet, or an AR headset.
For example, if a machine has a QR
code, one scan provides immediate
access to its documentation. “Earlier,
staff would have to leave the floor to
search for the required documents, but
now the app provides not only a timesaving
alternative, but a user-friendly
one, too,” described Dr Schoisswohl.
If a malfunction occurs, the
PanePro is the section of the app designed
specifically for glass. It is used to identify glass,
report breakage, track production data, and
conveniently re-order right on the construction site
with a simple scan.
machine operator, foreman, or in-house
technician can take note of this in the
integrated ticket system and even add
a photo. The app informs the service
staff immediately, providing an initial
impression of the measures to be taken.
In this way, the head of production or
service always has an overview of the
work to be carried out, can prioritise,
delegate, and even have its completion
process documented.
Support in production
Missing production documents, glass
set down in the wrong location, and
the search for a rack are among the
most frequent difficulties and delays
that plague a smoothly dovetailed
production chain. HELGA New
Technology developed the “PanePro”
section of Shop-Floor Assistant
especially for such everyday tasks.
If a pane is laser-marked or has
labels, one scan via smartphone is
enough to pinpoint it at any position
in the production chain, query its
progress, or request a replacement in
the event of damage. It is also possible
to identify a rack and its load via scan,
or configure a repair ticket if necessary.
When the integrated rack tracking
function is used, the rack only needs
to be selected from the display and its
current location information will be
output.
Digital support for employees
“Our aim is to design simple, practical
mobile digitalisation for operators,” said
HEGLA Managing Director Bernhard
Hötger. All the more reason to design
an app that can intuitively provide
information without requiring access to
a machine terminal.
“The competitive pressure is
increasing, and it is becoming ever
more important to support people with
digitalisation, ensuring that their work
and expertise can make an optimal
contribution to value creation,” added
Hötger. In his opinion, reducing the
time it takes to carry out sideline
activities is an important step toward
increasing productivity.
Shop-Floor Assistant has a modular
structure and can be implemented in
stages, whether it’s to call up machine
data or for rack and glass logistics, onsite
pane identification or specific sets
of tasks that need to be digitised.
Scanning a QR code or barcode on the machine provides direct access to its documentation.

Insulating glass
product types
Unique Design Structure Makes It Ideal Glazing
Material, A Product With Strong Growth Prospects
Strong, resilient, with perfect thermal and sound insulation
properties, insulating glass has been used around the world
in applications ranging from family homes to high-scale
construction.
Its unique design structure makes
it ideal glazing material and
a product with strong growth
prospects. But what makes insulating
glass the most preferred choice in so
many applications? Here, we discuss
the different types of insulating glass
units and their special characteristics.
An insulating glass unit is a
contemporary glass composed of
multiple panes sealed together with
air space in between, which gives
the glass its insulating properties by
separating the outside pane from the
inside pane. Thanks to this unique
arrangement, insulating glass is the
most effective way to reduce air-to-air
heat transfer through glazing.
Insulating glass dates back to the
1960s when the concept of saving
energy became popular. Today, when
used together with Low-E or reflective
glass coatings, insulating glass is even
more effective in conserving energy
and complying with energy codes.
Depending on the application,
insulation requirement or end user’s
need, insulating glass is available in
numerous different types. Design
versatility is based on factors, such
as the number of glass panes used
in the unit production, cavity-filling
material, coatings, sealing material
and others.
72 Glass Bulletin | October - December, 2020

Insulating glass for structural
glazing
Because ordinary glass fails to
sustain expected wind forces and
severe weather conditions, it is an
unsafe material choice for outdoor
applications. In turn, the increased
strength of insulating glass units
makes them the most preferred glass
type for residential, commercial and
industrial structural glazing. Multiple
layers of glass boost the strength of
the design element, making it more
durable, resilient and secure.
What also makes insulating glass a
perfect choice for windows and doors
is its adaptability to different seasons.
Insulating glass was primarily designed
to protect glazed areas from excessive
heat loss or gain. During the summer,
this glass blocks the sun’s heat from
entering into the interior. In the
winter, it prevents indoor heat from
escaping outside.
Basically, insulating glass is truly an
eco-friendly glazing option. Thermal
insulation allows it to take the load
off heating and cooling equipment. It
also makes it much easier to achieve
a desired indoor temperature without
excessive use of power and energy.
And this is a big deal when reducing
heating and air conditioning costs, as
well as the carbon footprint.
Compared to ordinary single glass,
insulating glass also has the added
advantage of minimized condensation
issues.
But from the design perspective,
insulating glass offers a wide range
of solutions for both large and small
structural glazing projects. It can
be used, for example, to construct
visually impressive all-glass façades or
compelling architectural façades by
using profiles that are only visible from
the internal side.
Sound control glass
With increasing road, rail and air
traffic, noise insulation has become a
very important glass property. Today,
noise insulation is an undisputed
requirement in building construction
to help eliminate stress and noiserelated
issues.
Insulating glass, in turn, is a perfect
barrier against undesired noise. Its
effective sound control feature makes
it ideal for residential applications
where the need for seclusion is
important.
Without sacrificing daylight, the
desired acoustic performance of sound
control glass is achieved by combining
various thicknesses of glass with a PVB
interlayer within the double-glazed
unit. When even greater sound control
is required, adding a wider space
between the glass panes can help.
Glass Bulletin | October - December, 2020 73
Technical Article
Bulletproof glass
Widely used in bank counters, escort
vehicles and other security-related
applications, bulletproof glass is
another product type where insulating
glass is preferred.
Bulletproof glass is produced by
combining two or more sheets of
glass with PVB interlayers to prevent
a bullet from passing through. Its
lamination property enables the glass
to provide impact protection and extra
security. If damaged, the glass breaks
into numerous small cullets, reducing
the risk of serious injury.
Higher levels of security are
obtained by increasing the number of
layers and glass thicknesses.
The insulating glass used in bulletproof applications is typically up to five times
stronger than annealed glass of the same thickness and eliminates the risk of
thermal fracture.
Fire-resistant glass
Fire-resistant glass (FRG) is
designed for interior and exterior
use when thermal protection is
required in case of fire. This type
of safety glass is mainly produced
using clear, multi-laminated, fully
insulating glass.
Different fire-resistant glass
units offer varying levels of
protection. These are measured
in terms of glass integrity and
insulation levels. The integrity
characteristics determine the time
the glass remains intact in a fire.
Insulation defines how much the glass
limits the temperature rise on the
non-fire side.
Depending on the product quality,
fire-resistant glass should also ensure
protection from radiation and passive
protection from the effects of fire for
up to 180 minutes.
As you can see, there are different
types of insulating glass, each with
its own composition, performance
characteristics and purpose. Still,
one thing remains constant – all
insulating glass has unrivalled heat
insulation, sound insulation and
impact resistance.

Waste glass processing: REDWAVE
enhances dark glass recovery
technology
Sensor, Software Can Be Upgraded, Eliminating Need For Facility
Extensions, More Sorting Machines
Glass recycling in Europe has become a significant industry. By using high-end sorting
technologies such as X-ray fluorescence and LED camera systems, a recycling rate of glass
of up to 74% can be achieved in current glass recycling facilities. The obtained recycled
glass can be used as a substitute for the glass re-melt industry for the production of new
glass containers.
Until now, the sorting process
in such a recycling facility
has caused a significant loss
of good cullet especially into the CSP
reject stream (Ceramics, Stone and
Porcelain) with glass contents of up
to 90%.
The reason for this significant
loss in glass is the result of outdated
sorting techniques. Due to the low
transmission value, dark and thick
glass pieces cannot be told apart from
CSP and are ejected along with the
CSP by optical sorters. This will result
in lower output rates and increased
disposal costs for the CSP reject
stream due to the higher volume.
REDWAVE has taken on this
challenge and through continuous
research and development of its
glass sorting sensors and software.
REDWAVE has achieved superb
detection rate of dark glass. Detection
of dark glass has improved by more
than 50% while there have been no
losses when it comes to semi-coloured
glass or thin porcelain. This new
REDWAVE sensor and software can
easily be upgraded thus eliminating
incurring costs on facility extensions
and avoid the need to purchase
additional sorting machines.
FURTHER USAGE POSSIBLITIES
Establishment of an independent level
for recovery of glass from CSP-rejects
of existing plants.
REDWAVE offers the possibility to
sustainably reduce losses of glass in
facilities through brand-new machines
and upgrade packages and eventually
adds an invaluable contribution to
the increase of productivity rates in
plants.
About REDWAVE
REDWAVE delivers profitable solutions in
the recycling and waste industry. It supplies
groundbreaking and economic sorting plants for
recyclables as well as turnkey waste treatment
plants. It is a leading manufacturer of sensorbased
sorting machines with a sturdy industrial

Printing glass is also possible!
Scientists Plan To Exhibit 3D Printed Glass Staircase With Glass Brackets At
glasstec 2021
Metals, concrete, and plastics are all materials which can be printed. But what about glass?
Companies, institutes, and universities are researching the possibilities and have been able
to gain experience from experimental procedures.
The most common materials
used here are silica glass
or borosilicate glass, while
applications using soda-lime glass are
less common. Printed glass can be
used in many applications, which is
why it is certainly worth investing time
and money into research.
Glass is becoming ever more
popular in building architecture as
it is deemed a modern and elegant
material. The growing demand for
large and custom glass façades which
can take on additional functions is
spurring on designers. Glass fronts
must not only be aesthetically
appealing, but also securely installed
and durable, as well as being able to
permanently withstand the enormous
loads they are under.
However, visible joints
and load take-up points
disrupt the image of a
homogeneous, transparent
façade. In general, attaching
the panes requires holes to be
drilled in the individual elements,
which harbours the risk of damaging
the glass and thereby reducing its
strength.
Another option is to use adhesives
to join components, but this has
the disadvantage that the adhesive
materials can age quicker than the
joined parts due to UV radiation. A
further aspect is that joined elements
with different mechanical and thermal
properties are used for both drilled
and glued joints.
Using glass from a 3D printer
as a joint material, for example for
point fixing, results in two identical
materials with the same properties
being joined together. This avoids
different heat expansion factors
between the materials, and the risks
inherent with using drilled holes or
adhesives are no longer a factor.
The Glass Competence Center at
the Technical University of Darmstadt
is conducting research on how to
create a substance-to-substance
bond on float glass using additive
manufacturing (3D printing), while
simultaneously increasing its rigidity.
Scientists are testing fused
deposition modelling, amongst other
approaches. Their aim is to enable
glass panels with an area of up to
3.25 x 20 metres in the future. Two
important factors are the process
temperature and the viscosity of the
glass.
In
order to create
a joint between
a
pane and a glass structure, the pane
must be heated significantly beyond
the transformation temperature of
glass at the join. If insufficient heat
is applied, the structures will not join
together, while if the temperature is
too high, unwanted deformation can
occur. Internal tension in the joint
reduces its strength and ability to
support loads.
Brittle material behaviour and a
combination of individual process and
material parameters can also have
a significant impact on the result.
It is, however, absolutely possible to
manufacture a homogeneous joint in
a desired geometry with an appealing
and transparent appearance using
3D printing. The scientists at TU
Darmstadt also hope to find an answer
for the question of how to convert this
procedure into an automated process.
Visitors to glass technology live at
glasstec 2021 can also look forward
to a further research project, as the
scientists are planning to exhibit a
3D printed glass staircase with glass
brackets.
Just like glass
When comparing the material
properties, environmental impact and
raw material properties of glass and
plastic, glass comes out on top across
the board. Unfortunately,
melting glass is both
complex and expensive,
which is why the industry
prefers plastic in part.
The general methods used to
process glass have hardly changed
over the centuries, with the most
common being grinding, polishing or
etching. Glassomer GmbH develops
materials and technologies which
first enable the shaping of polymer
nanocomposites at room temperature,
before they are subsequently
converted to glass at temperatures
between 700°C and 1300°C.
Glassomer® is a silicate
nanocomposite, which enables highly
pure quartz glass to be manufactured
from a solid, paste or liquid state.
Liquid Glassomer can be used to
duplicate components at room
temperature through casting or
stereolithography. Solid Glassomer
can be structured using traditional
subtractive techniques such as
drilling, milling and turning, or
even with a knife. Thermal polymer
76 Glass Bulletin | October - December, 2020
VDMA • 2
transformation technologies such as
nanoimprinting, thermoforming or
roll-to-roll replication are also possible.
Glassomer components are
chemically and physically identical to
commercial quartz glass. They have
comparably high optical transparency
in the visible, UV and infrared spectra,
as well as equal thermal and chemical
stability and mechanical strength.
Additional solids in the starting
material help prevent the glass from
shrinking during manufacturing.
It is also possible to manufacture
components with threads. Simple
technologies, such as casting, enable
uncomplicated replication, and
smaller components can be created
using simple 3D printers.
More complex tasks require highresolution
microstereolithography.
Using this procedure, extremely fine
structures with diameters of just
tens of micrometres can be created
without transitions. Glassomer is the
first product to enable the structuring
of high-quality quartz glass using
polymer processing technologies. The
replication is accurate right down
to just a few micrometres and the
resulting glass has a surface roughness
of a few nanometres, which meets the
demands of both optics and photonics
applications. Users can create voids
in bodies using sacrificial templates
and extremely fine structures in bulk
materials.
Melt first, then print
The Günter Köhler Institute for
Joining Technology and Materials
Testing in Jena collaborated with FH
Aachen University of Applied Sciences
to analyse laser powder bed fusion
(L-PBF) of borosilicate and quartz
glass powders within the process
chain of 3D printing. This procedure
has benefits including free geometric
shaping, low production costs in small
and medium-sized production runs
and comparable component properties
of the glass bodies.
The scientists characterised the
glass powder classes based on their
geometric, thermal and mechanicalphysical
properties, and analysed how
they can be processed at different laser
wavelengths in the L-PBF process.
To this end, the plant technology
was adapted to the conditions of
processing glass using CO2 laser
radiation. The effort is worth it,
as glass meets requirements in
glass equipment or chemical plant
construction that metal cannot.
Glass has a high temperature
resistance, thereby requiring a high
energy input to melt, and is a poor
conductor of heat. Scientists wish to
investigate how they can overcome
this factor and the poor absorption at
the wavelength of 1,064 μm.
They were already able to prove
that it is generally possible to process
glass powders and define process
parameters, such as laser power,
scan strategy, powder coat thickness,
chamber heating and much more.
Researchers manufactured test
specimens made of borosilicate and
quartz glass and subsequently assessed
their quality.
The parameters were strongly
dependent on the geometric shape
of the specimen due to the heat
agglomeration. Tempering can help
improve the quality of the glass
components. Further experiments
aim to test the porosity, roughness
and density in relation to the L-PBF
parameters and clarify the possible
application areas for the components.
The thermal and chemical
resistance inherent to quartz and
borosilicate glass have resulted in
them becoming proven materials
in glass equipment construction,
microfluidics, microelectronics, optics
and medical technology.
A further research project at ifw
Jena aims to develop an additive
process based on laminated object
manufacturing (LOM) with the goal
of enabling additional industrial
applications. In this project, complex
glass components – for example with
interior cavities – are constructed
which could not be manufactured
using conventional fabrication
technologies.
The procedure is intended to
combine laser cutting and diffusion
welding. Aside from quartz glass, CO2
laser cutting (λ = 10.6 µm) causes
the glass composition in the area of
the cut edge to change, the thermal
expansion coefficient to shift and a
bead to form. The research goal is
to define process parameters for the
respective glass in order to remove
these effects.

Convection is simple; return air
flow makes the difference
Convection Process Is Based On Radiation Heating, But It Was Not Known
For Quite Some Time
In the end of 1980’s the most popular and famous tempering furnace was the HTF series of
Tamglass Engineering Oy. It had a very accurate heating profile with C-C distance of heaters
120 mm.
However, it had no matrix heating system. The heater lengths were as
long as the heating length. Another alternative was that the heaters
were divided into 3 lengths; longer in the middle of the furnace and
shorter heaters at the ends. The heaters were difficult to change and also
expensive.
Also a known problem in radiation heating was cooling of rollers with
continuous loading of full batches. Also the rollers were too hot when the
furnace was empty. This caused breaking of glasses in the furnace and other
operational and glass quality problems.
Teaching of radiation was forgotten
Other known glass tempering machine manufacturers were English EFCO
and Swiss Cattin. They already used short, open resistors so they had a matrix
heating system. EFCO planned
convection heating as low emissivity
glasses entered into the market early
1990’s.
However, Cattin and German
company WSP made convection
furnaces. Cattin and WSP blew
uniform temperature convection air
onto the glass as the convection air
heaters were before the blowers.
They did not have any heating
profile and no matrix heating even
for radiation. They did not maintain
roller temperatures stable. Both were
poor for all glass types, but had high
heating speed.
Simple things are difficult to
realize, but simple ideas can make
wonders, too.
Italian IANUA made the first
effective convection process in 1996
Tamglass HTF (HTBS/HTS)
technology was used for the machine.
Also for control system. The
convection air was blown “through”
the heaters. This is why the heating
control configuration of HTF was
transferred into the convection air.
Another handicap of radiation
heating was also avoided. The
convection onto the rollers kept the
roller temperature stable and the
bottom glass temperature followed
the top heating configuration.
The heating and the furnace were
called “CONVAIR”, CONvection,
and IRadiation. The fact is, that it
included only slight radiation as the
furnace temperature was below
700 °C.

some other little details
IANUA patented expensive and
unnecessary things; nozzles machined

should have patented how to heat the

over the heating area. This alone would
have made CONVAIR an unbeatable
convection heating machine for over
20 years!

almost the same as in CONVAIR.
GLASSROBOTS had to add nozzles
all over the top convection. This and
narrow nozzle boxes made the design
expensive.
A Chinese company experience of
copying and modifying RoboTemp:
The company tried to make it cheaper
by very wide nozzle blocks. They also
installed nozzle boxes into the angle
compared to the glass travel direction.
Other cost reduction method as
shown below:
These systems do not meet low
emissivity glass requirements since:
99
The radiation matrix heating
does not works for low emissivity
glass
99
They have very low capacity for
low emissivity glass
99
Their convection coverage is
about 33% of the heating area
and/or the convection is weak
However, for example the system
shown on the right side has high
capacity clear 5 mm glass, about 22
loads/hour. It is obtained by high
radiation heating intensity of about 90
kW/m² of the heating area added with
convection. For triple silver glass 5 mm
glass the capacity is just 12 loads/hour.
The above systems just circulate
convection air in the furnace but not
heat it. This is the main reason for low
capacity with low emissivity glasses.
These systems really work like radiation
heating furnaces. The radiation

heating furnaces have lower yield and
they have more glass quality problems
like edge kink.
Another problem with this type of
the furnaces is that the thermocouples
are affected by the radiation, the return
air flow of various matrixes, mix of
the convection jets and the return air
flow. This is why the thermocouples do
not give the correct reading matrix by
matrix as they should.
How the convection problems and expenses can be tackled?
Feracitas convection unit and its applications. Number of units depend on the heating length.
Comment A:
Box convection eliminates nozzle
boxes and excessive ducting. Over
dimensioning of heating power and
convection blowers is not necessary
when the convection return air flow
is correctly arranged. The patent US
7 290 405 has expired but can be
used. However, not with nozzle box
convections.
Comment B:
The heaters are inside of the
convection unit. In CONVAIR,
RoboTemp and other good “pure
convection” methods they are inside
nozzle boxes.
Comment C:
The patent US 9,624,120 protects the
idea for the return air space. A small
under pressure at the top of the furnace
sucks the return air flow through the
return air space back to the blowers. It
works according to the Bernoulli effect
from the 16th century. The pressure
loss is only 4 – 7 % and working range
very large, secure. The benefits:
99
The convection coverage can be
100% of the heating area and
99
The convection jets do not hit
into the return air flow

These are the key factors to the
effective heat transfer and high

Notes:
1. The process in all alternatives
remains the same. Only the
return air flow is different.
Nothing is missed from
comments A and C.
2. Even comments A and C
and the 2 patent applications
can be combined into the
same package. However, if
the 2 patent applications are
combined together, an extra
cost applies.
3. All the convection embodiments
can be fitted into the same
furnace body and software with
minor changes in them.
The economic effects
The glass tempering can waste up to
80% labor wages when tempering 5
mm triple silver glass. This is due to
the waiting time, which is needed for
the glass to be hot enough to temper
it. This waiting time is the biggest
contributor to energy waste, too.
These wastes can only be reduced
by high heating speed. In high labor
cost countries this is huge money every
year. In some countries energy cost
savings are more important
Naturally also investment cost and
payback time are important.
All can be calculated by a simple
EXCEL sheet by inserting local costs
expenses and glasses divided into clear
glass and triple silver glass. This is an
example for 2 shift work in a high labor
cost country. 2/3 of the glass is triple
silver glass and 1/3 clear glass. Payback
time is 7 years.
This does not include breakage,
which is higher with the convection
processes, which function like
radiation heating furnaces. Also proper
convection heating furnaces produce
better quality glass.
