INSULATION
In-patient unit insulated with Kingspan
Kingspan Insulation products
have been installed
throughout the envelope of
the new in-patient unit at
St David’s Hospice Care in Newport,
creating a warm, comfortable
environment for patients to receive
first-class care.
The 15-bed unit adjoins an
existing day hospice, providing
specialist support for patients with
complex symptom management
needs, end of life care and
occasional respite care. Each room
features a wet room and a private
terrace, providing views of the
newly-planted wildflower meadow
and hills beyond. The Welsh
Government has provided £3 million
towards the cost of the unit which
has been constructed by Andrew
Scott Ltd.
KKE Architects selected natural
materials for the building cladding,
including tumbled sandstone and
cedar shingles, providing it with a
welcoming external appearance. To
ensure a slim external wall
construction whilst also achieving
the target U-value of 0.16 W/m2.K,
Kingspan Kooltherm K8 Cavity Board
was specified within the cavity wall
sections of the construction.
The unit, which holds an Energy
Performance Certificate of A, also
features a highly insulated floor and
roof, with both elements achieving a
U-value of 0.10 W/m2.K. To deliver
this, almost 3000 m2 of Kingspan
Kooltherm K3 Floorboard was fitted
along with Kingspan Kooltherm K7
Pitched Roof Board and Thermaroof
TR27 LPC/FM.
Kyle Fowler, Architectural
Technologist at KKE Architects
commented:
“The Kingspan Insulation
products delivered reliable
performance, enabling us to achieve
our desired design details. We were
also able to contact their technical
support team throughout the design
process, ensuring the completed
elements performed as expected”.
Since the completion of the inpatient
unit, Kingspan has launched
its Kooltherm K100 range offering
thermal conductivities of just 0.018
W/m.K across all thicknesses. The
expanding range now includes K103
Floorboard, K107 Pitched Roof Board
and K108 Cavity Board, helping
buildings to achieve outstanding
levels of thermal performance with
a minimum construction thickness.

Rockwool passes the ‘Terminal 4’ accoustic test
Noise pollution is an
inevitable fact of life at
busy airports, and results
in hoteliers in these
locations needing to minimise the
impact of unwanted noise on their
guests. Thanks to a pioneering
approach from ROCKWOOL that is
based on acoustic performance test
data and use of its BBA (British
Board of Agrément) approved A1
rated RAINSCREEN DUO SLAB®
insulation product, the new Crowne
Plaza and Holiday Inn Express at
London Heathrow Terminal 4 will be
providing visitors with a peaceful
and tranquil stay when it opens later
this year.
Connected via a convenient air
bridge to Terminal 4, this dualbranded
hotel development includes
Crowne Plaza and a Holiday Inn
Express, with a combined total of
750 rooms. There is also a range of
onsite business facilities, including
five meeting rooms, to enable guests
to be at their most productive
during their stay. Minimising
external noise from the UK’s busiest
airport, where the average number
of air transport movements reached
1,295 per day in 2017, was a major
factor in this build. To this end,
Grove Developments, the
construction division of The Arora
Group, who is overseeing the
project, challenged ROCKWOOL to
achieve a significant Rw 58dB sound
reduction within the façade system
used on the development.
Using test results from its
Rainscreen Acoustic Reference
Guide, and working closely with
sub-contractor, SD Samuels,
ROCKWOOL was able to demonstrate
the exceptional performance
capabilities of its 150mm
RAINSCREEN DUO SLAB® product for
the hotel development project. As a
result, 5200m2 of the product was
specified.
RAINSCREEN DUO SLAB is a noncombustible,
dual density insulation
board that offers a robust outer
surface and a resilient inner face
designed for a variety of external
cladding systems. Made from stone
wool, RAINSCREEN DUO SLAB
reduces noise intrusion into a
building in multiple ways.
As soundwaves try to pass
through the air trapped within its
fibrous structure, they get absorbed
by friction as the individual fibres
are made to move back and forth. In
addition, the random orientation of
the fibres makes it very difficult for
sound to find a path from one side
to the other. The top 15mm layer of
each RAINSCREEN DUO SLAB board
is manufactured at a higher density
than the remainder of the board,
changing its acoustic impedance so
that sound is reflected at the
interface between the two layers.
RAINSCREEN DUO SLAB achieves
an A1 Euroclass fire classification
and is therefore non-combustible.
The product also has the benefit of a
high resistance to wind and rain
during construction, which, together
with the minimal number of fixings
required, made installation quicker
and easier for SD Samuels. At the
Crowne Plaza and Holiday Inn
Express, the product was tightly butt
jointed, knitting together to deliver
an effective thermal insulation with
a U-value of 0.20 W/m2K. It has also
minimised heat loss that could
otherwise arise from gaps between
insulation boards.
