Why Choose PVCu? 

uPVC (unplasticised PolyVinyl Chloride) was the term used 

in Britain before the name was changed to PVCu in the late 

1980s to fall in line with the rest of Europe. It’s called PVCu on 

the continent because most European languages place the 

noun (the word PVC in this case) before the adjective (U). 

8

Thermally Efficient 

It’s well known that PVCu is a low conductor of heat, 

helping to retain warmth within a building and keep 

the cold out. This is further enhanced by designing 

multiple chambers inside the window profiles, 

allowing them to trap air and create a thermal 

barrier. 

Add double or triple glazing to a PVCu frame, and 

U-values as low as 0.8 W/m²K can be achieved. 

PVCu outperforms any other material, with 10 

times more PVCu windows achieving an ‘A’ rating 

compared to the nearest alternative. 

Attractive 

The old chunky white PVCu frames seen in the 1980s 

are well and truly in the past. With a wide range 

of woodgrain effects and colours, as well as slim 

sightlines, PVCu windows can be as aesthetically 

pleasing as their timber or aluminium counterparts. 

Designs have advanced to the extent that sashes 

can sit flush in the frame, mirroring a pre-1932 style 

timber frame – ideal for conservation properties 

where timber is preferred, or alternatively to offer a 

sleek, contemporary appearance. 

Durable 

PVCu windows have an expected life span of up to 

35 years. 

Frames will not rot, corrode, warp or split, and special 

additives make them tough enough to suit European 

requirements. 

In addition, the lightweight nature of a PVCu frame 

makes it easier to handle and install, reducing time 

on site for fitters and contractors. 

9

Why Choose PVCu? 


With PVCu, the ongoing maintenance consists 

of a wipe down with warm soapy water, making 

them simpler and more cost effective to look after. 

Woodgrain or foiled windows with minor scratches 

can be repaired using a RAL-matched pen. 

Contrast this with timber windows – they need 

treating or painting on a regular basis, which is time 

consuming and can be costly. Aluminium windows 

can fade and oxidise when exposed to the sun, often 

requiring the use of specialist cleaners and coatings 

to restore. 

Weather proof 

PVCu windows are ideal for the damp British weather. 

The frames will not swell or rot, and co-extruded 

gaskets provide excellent resistance to air and water. 

With both timber and aluminium frames, the seals 

are added in afterwards. Joints can 

also shrink back over time, causing gaps in 

the seals. 

With PVCu, the gaskets are welded together as 

part of the manufacturing process, providing a 

continuous seal all the way round and eliminating 

draughts for longer. 

Benefit vs. cost 

There are three distinct areas where installing PVCu 

windows saves on cost and adds benefit: 

• Lower purchase price and installation costs 

• Higher energy savings over the life of the 

windows, and 

• Lower maintenance costs.

Steel Reinforcement - Busting The Myth 

1 

22

Many old ‘first generation’ PVCu windows relied heavily on steel 

reinforcement - but Liniar has redefined the rules. 

History 

For these ‘first generation’ windows, it was considered 

essential to securely fix hardware such as hinges 

and locking mechanisms, in addition to increasing 

the stiffness of the frame and reducing deflection 

when subjected to wind gusts 

For many years, this was the accepted make up of 

a PVCu window – and some are still manufactured 

in this way. In more recent times energy efficiency 

became a more prominent topic and the evolution 

of window products continued with the introduction 

of PVCu thermal inserts. 

These inserts replaced the thermally inefficient steel, 

occupying the same internal chamber and creating 

a multi-chambered thermal barrier in the same 

3-chambered profiles. 

Not exactly a giant technological leap, more of a 

‘gap filler’ and not without its drawbacks – these thin 

inserts add very little to the stiffness of a profile, nor 

do they provide a secure fixing for hardware. 

This resulted in many window systems providers 

having two different offerings – one which is 

thermally efficient (with thermal inserts) and one 

suitable for enhanced security (with steel). 

The Liniar solution... 

In 2007 the Liniar team set about designing a brand 

new system, with a blank sheet of paper and loads 

of new ideas – a system which would be both 

thermally efficient AND strong and secure. 

Firstly, there were to be no thermal inserts – the multichambered 

effect was designed to be part of the 

profile, with both the amount of internal webs and 

their spacing being fine-tuned with Therm software to 

achieve exceptional thermal performance. 

This principle could only be applied to specific 

profiles within the system, with transoms and mullions 

remaining steel-reinforced using a steel box section 

within the central chamber – this provides the rigidity 

needed within the frame. 

Secondly, the issue of secure fixing for hardware was 

addressed by incorporating a rectangular pocket 

directly behind areas where fixings would be used, 

achieving screw pull-out forces equivalent to that of 

1.2mm thick steel when inserted with a PVCu screw 

retainer (1). 

The Liniar window system has been independently 

tested and verified by the British Standards Institute, 

meeting PAS 24 with reduced steel and BS6375; air 

and water leakage. 

23

The Science Behind the System 

2 

Patented Bubble Gasket (2) 

Historically, PVCu window systems were fitted with a 

range of EPDM (rubber) gaskets at the fabrication stage, 

similar to the method still used on timber and aluminium 

windows. The resulting permeability of the assembled 

frame was dependent upon the quality of each seal 

joint, with many suffering from draughts and wind noise. 

The PVCu extrusion process lends itself to the wellestablished 

technology of co-extrusion - adhering 

the gasket onto the frame using a separate extrusion 

machine during manufacture. This evolutionary step 

eliminates the time-consuming gasket insertion process 

and creates a more reliable corner seal at each joint. 

Many PVCu window systems make use of co-extruded 

gaskets, most adapting existing profiles to the process. 

Starting from scratch, the Liniar team had no constraints, 

and spent a significant amount of time developing 

its patented bubble gasket to outperform all others in 

speed of fabrication and in permeability - achieving 

a zero air leakage during independent tests at BSI.The 

24

design of both the gasket and the area behind the 

gasket is crucial, not only to the permeability of the 

finished window, but during the welding process where 

hard lumps can form in the corners of each joint, 

cracking sealed units. Liniar’s dual-action gasket performs 

equally well as a soft dynamic seal on opening sashes 

as it does as a firm glazing gasket for sealed units, its 

tolerance friendly design always ensuring a whistle-free 

seal inside and out – and no gaps, not even in the corners. 

Enhanced Thermal Performance 

As the quantity and spacing of internal webs reduce 

thermal transmittance through Liniar frames, the flow is 

directed towards the path of least resistance. To address 

this, the Liniar design team introduced a brace of simple 

but effective ancillary products. 

The first is the innovative glazing flipper (3) – this can 

be clipped onto the short central up-stand within the 

glazing area, creating a thermal barrier and additional 

3 

gasket, and sealing the perimeter of any glazed unit - 

keeping the heat in and moisture out. 

The second is the patented thermal dam (4) – 

introduced to address heat loss at the outer edge of 

the frame, Liniar’s clip-in thermal dam creates a multichambered 

barrier with optimized leg spacing and is 

manufactured from recycled material produced during 

4 

the extrusion ‘start-up’ procedure. 

The result is a supremely energy efficient double glazed 

product, one capable of achieving a cost-effective 

A+ Window Energy Rating, or 1.2 Wm²/K U-Value and if 

required a triple glazed 0.8 Wm²/K U-Value window.

Part B 

Part B refers to fire safety and is divided into 2 sections. 

Part 1 addresses dwellings (residential buildings 

shared by 6 or less people) and Part 2 buildings other 

than dwelling houses. 

Any windows provided for emergency egress 

purposes and any external doors provided for 

escape should comply with the following conditions: 

• the window should have an unobstructed 

openable area that is at least 0.33m 2 and at 

least 450mm high and 450mm wide (the route 

through the window may be at an angle rather 

than straight through). 

• The bottom of the openable areas should not be 

more than 1100mm above the floor. 

All Liniar windows are capable of achieving this, 

meaning any Casement, Tilt & Turn, French or Flush 

Sash, are ideal as fire escapes.

Part F 

Part F details ventilation requirements to maintain 

indoor air quality. 

For both new and existing buildings the key aim of 

Part F is to provide a ventilation system capable of 

limiting the accumulation of moisture and pollutants 

originating within a building which would otherwise 

become a hazard to the health of the people living 

within the building. This has become more prominent 

in recent years with the increase in air tightness 

of buildings. 

Liniar windows can assist with background ventilation 

by fitting windows with head vents, providing secure, 

draught-free ventilation (see page 48).

Part L 

Part L refers to conserving fuel and power, by raising 

the energy performance of buildings. It is divided 

into 4 sections addressing new dwellings existing 

dwellings, new buildings other than dwellings and 

existing buildings other than dwellings. 

Where windows, roof windows, or doors are to be 

provided, reasonable provision in normal cases would 

be the installation of draught-proofed units whose 

performance is no worse than given in Table 1. 

In addition, insulated cavity closers should be 

installed where appropriate. Where the replacement 

windows are unable to meet the requirements of 

Table 1 because of the need to maintain the external 

appearance of the facade or the character of the 

building, replacement windows should meet a centre 

pane U-value of 1.2W/m²K, or single glazing should 

be supplemented with low-e secondary glazing. In 

this latter case, the weather stripping should be on 

Standard for controlled fittings 

the secondary glazing to minimise condensation risk 

between the primary and secondary glazing. 

Liniar systems exceed Part L requirements, achieving 

BFRC A++ ratings with ease. Liniar also provides a 

database of over 1,000 BFRC simulations to refer to.

following conditions: 

• Requirement M1 will be satisfied if an external 

door providing access for disabled people has 

a minimum clear opening width of 775mm. 

• The threshold level is level; if a raised threshold 

is unavoidable, it has total height of not more 

than 15mm, a minimum number of upstand 

and slopes, with any upstands higher than 5mm 

chamfered or rounded. 

All Liniar doors are available with Part M compliant 

low thresholds, threshold trays and half trays. 

For more information please refer to Approved

Part Q 

Part Q covers the security of dwellings and refers to 

new dwellings only. Reasonable provision must be 

made to restrict unauthorised access to any dwelling, 

and any part of a building from which access can 

be gained. 

It also covers the standards for doors and windows 

to be“manufactured to a design that has been 

shown by test to meet the security requirements of 

British Standards publication PAS24/PAS 24:2016, or 

equivalent enhanced security testing. 

Liniar products meet this standard, by exceeding 

the requrements for Part Q. Liniar provides a Part 

Q manual including detailed illustrations and 

instructions to explain how to achieve compliance 

for every Liniar product in the range.

Recycling and Sustainability 

PVCu is now recognised as a sustainable option when it comes to 

fenestration products, with the Liniar range leading the way in its 

environmental credentials. 

All PVCu windows are recyclable, but the Liniar 

system is simpler, and cheaper, to recycle at the end 

of its life than other systems. The low steel content 

conditions and systems, have as little effect on the 

environment as possible. 

It is the company’s policy to: 

in a Liniar window results in speedier separation 

of PVCu and steel and our externally mounted 

ModLok products can be separated in seconds, 

As each window can be recycled up to 10 times, 

this gives PVCu windows an estimated life span of 

350 years – more eco-friendly than depleting timber 

resources. As a company, Liniar continually strives to 

improve its environmental performance and reduce 

its carbon footprint, and has even developed new

WERS and Energy Efficiency 

WERs (Window Energy Ratings) show 

how energy efficient a window is. 

The Window Energy Ratings scale is designed by the 

British Fenestration Ratings Council (BFRC) to measure 

the thermal performance of windows, and enables 

different windows to be compared on a scale that runs 

from A++ down to E. 

The rainbow labels you will see are simiar to the ones 

found on household appliances, such as a TV, fridge or 

freezer. A++ is the most energy efficient and 

E the least efficient. 

The formula used to calculate a WER takes into 

consideration various factors: 

• U-value (of the glass Ug and frames Uf) 

• the solar heat gain of ‘G value’ of the glass 

• air leakage rate of all the components of the fitted 

window 

The U-value is the measure of heat loss in watts (W) per 

square metre (m 2 ) of the material when the temperature 

(K) outside is at least 1 degree cooler. 

When the U-value has been calculated it is combined 

with the solar gain of the glass and the air leakage rate 

and given a numerial BFRC rating, this is then converted 

into a band A++ to E. 

Building regulations now state that new homes must 

have windows with an energy rating of at least C or a 

U-value of 1.6W/m 2 K 

Passive House 

Passive House is a rigorous voluntary standard for energy 

efficiency in a building, reducing it’s carbon footprint. 

The new Liniar EnergyPlus90 system, can achieve 

U-values as low as 0.5 W/m 2 K - standards for Passive 

House.

Case Study - Energy Efficiency 

Liniar Helps Generate Energy For Eco-House Project 

As seen on 

BBC1’s 

100K House 

Four years ago, Jo and Andy Thompson were living 

in social housing at Unity Gardens, Long Sutton, 

Lincolnshire - one of the UK’s first zero-carbon 

housing developments. 

“We were inspired by the development that we 

used to live in, which was eco-friendly with no utility 

bills, so for our home, we employed the help of 

local architect Dr Jerry Harrall, who is known for his 

involvement in eco-friendly developments.” 

The weakest area of a house is traditionally the 

windows, as this is where most of the heat is lost. 

Standard house builders will usually get U-values of 

around 1.7W/m 2 K - but the aim for this property was 

to get below 1.0W/m 2 K. 

“We hadn’t heard of Liniar windows before, but our 

architect recommended them as he had used them 

in previous projects,” explained Andy. 

They found a local installer who ordered windows 

with Liniar EnergyPlus profile, plastic composite 

spacer bar, triple glazing and low emissivity film on 

the inside and outside to achieve a U-value of 

0.8W/m 2 K. 

By using this combination, the heat loss from the 

house was reduced by 50%. The windows were 

installed on a layer of external insulation as opposed 

to the usual cavity, to further increase thermal 

efficiency. 

“We’re delighted that the building is ‘Energy Positive’ 

by 40% - meaning that it generates 40% more energy 

than it uses,” said Andy. “Putting that into numbers, 

our house generates around 5,000 kWh of energy a 

year, but we only use around 3,000 kWh.” 

35

Case Study - Casement Windows & Lantern Roof 

School project proves to be a real education. 

The challenge of transforming a 100-year-old school 

building into upmarket residential homes is no mean 

feat – but that is exactly the task that one building 

firm has undertaken and the outstanding result puts 

them top of the class. 

The old Shirland Primary School, near Higham in 

Derbyshire, became available to buy after the school 

was relocated to a new building in 2011 and Linden 

Design & Build Ltd purchased it, with planning 

permission, in June 2014. 

The existing site consisted of a two storey brick built 

schoolmaster’s house, formerly used as school 

offices, and a substantial brick built school building, 

along with a tarmac surfaced playground. 

Linden Design & Build’s plan was to develop the 

schoolmaster’s house into a single dwelling and 

split the other building into four houses, while 

also erecting five new properties on the land - 

one 4-bedroomed detached and two pairs of 

2-bedroomed semis, all with garages. 

Don Berry of Linden Design & Build, explained: 

“Firstly we had to replace all of the roofing and 

render the two existing buildings before installing 

new windows and doors. Because of the nature 

of the properties, the windows were going to be a 

fundamental feature of the finished design. 

“We chose cream foiled casement windows to give 

the properties a classy appearance, with French 

doors, a lantern roof and residential doors to match.” 

Linden Design & Build specified a minimum U-value 

rating of 1.6 but was delighted that the windows 

actually achieved an impressive 1.3! 

As the properties are situated next to a busy 

residential road, acoustic laminated glass was also 

utilised to keep traffic noise down to a minimum. 

“Liniar products are superb,” said Don. “They’re easy 

to install, have outstanding thermal values and look 

simply stunning. We couldn’t be more pleased with 

the results!”

ModLok 

Developed by Liniar in conjunction with the world’s leading lock 

manufacturers, the revolutionary ModLok technology is 

available in our residential, French, bi-fold & patio door systems 

ModLok for Residential, French and Bi-folding doors 

ModLok is a highly innovative combined 

reinforcing and locking mechanism, bringing 

additional strength and rigidity to the doors and 

enabling you to have even wider configurations of 

bi-folding and patio doors. 


The Liniar bi-fold door provides the strength and 

rigidity of an aluminium bi-fold combined with the 

thermal efficiency and colour options of a PVCu 

door. The ModLok exo-skeletal system ensures only 

the master door will open first, so there’s no chance 

of spraining locks by trying to open the wrong door. 

The shootbolt locking mechanism designed 

inside, not only maintaining the sleek lines but 

enhancing security as they can’t be unscrewed 

from outside. 

We wanted to offer a low threshold, without the 

need for expensive and messy excavation, so we 

designed our own clever solution. 

We’ve even designed folding keys to avoid any 

problems with them being left in the locks during 

operation – it’s often the small things that make a 

huge difference. 

Continual aluminium exoskeleton perimeter 

into each Liniar ModLok bi-folding 

door ensures that it is bolted firmly into 

the stainless steel track, maximising 

security. 

Built in anti-lift features, anti-bump 

cylinders and optional anti-snap cylinders 

combine to bring you peace of mind. 

Size wise 

ModLok also offers enhanced security 

features, including three opposing hooks and 

two shootbolts built in to every master door, 

plus two anti-lift shootbolts on every slave door. 

Liniar’s ModLok has been designed to take 

the PVCu sector into new areas. Its fully patented 

aluminium exo-skeleton means that our bi-folding 

doors can now reach the same size parameters 

as their aluminium counterparts – you can choose 

up to 7 panes wide to span the entire width of your 

garden room and open it to the outside. 

We’ve added slim hinges with the fixings hidden 

62

ModLok for Patio doors 

The Liniar patio system features the innovative 

ModLok system to combine steel reinforcing 

with a high security locking mechanism – 

offering far greater security than other patio 

door systems. 


With four hook bolts plus two shootbolts at the 

top and bottom of the sliding door, the Liniar 

patio’s locking mechanism has been designed 

so the hooks don’t protrude into the room, even 

when the door is open, making it extremely 

family friendly. 

To make the patio door even more secure, 

choose the latest ‘anti-snap’ locking cylinders. 

With 3-star security, these cylinders offer even 

greater protection against the more determined 

would-be intruder using tools to break the 

cylinder and gain entry by manipulating the 

door to open. 

Low threshold option 

The Liniar low threshold is thermally broken, 

adding to the energy efficiency of your patio 

doors. As with the bi-fold low threshold, no 

excavation is required to fit the low threshold, 

cutting down on installation time and mess. 

Choose from silver or gold options to co-ordinate 

with handles. 

Better for the environment 

Not often considered when buying a new 

product for your home, ModLok technology 

has a big environmental advantage when the 

doors eventually come to the end of their life. 

Metal parts included in other PVCu systems 

mean that they cannot easily be recycled 

without lots of effort to strip them down. 

However, as ModLok comprises seamless steel 

sections, they are simple to separate once the 

doors are removed, enabling the PVCu to be 

recycled faster and with much less effort.

Case Study - French Doors 

Working in ‘Harmony’ for 1.6m Torquay luxury beach project 

A picturesque Devonshire beach front has 

undergone a stunning transformation – and 

Liniar French doors were used as part of the 

ambitious £1.6m development. 

Torbay Council contracted construction firm 

Interserve with the task of demolishing the 

old huts and replacing them with a modern 

complex. Headquartered in the UK, Interserve 

is one of the world’s foremost construction 

companies, with gross revenues of £3.3 billion 

and a workforce of approximately 80,000 

people worldwide. 

The scheme involved the huge logistical 

challenge of installing pre-cast concrete units 

in areas with restricted access. The design 

successfully aligned the new development to 

the sea wall, creating a tapered effect that fits 

in with the cliff backdrop and pine-studded 

cove. 

The two-storey complex of 144 luxury chalets 

has an upper tier with private balconies, each 

chalet fitted with an electricity supply, kitchen 

worktop and cupboards, to be available for 

use throughout the year. 

As part of the design for the project, double 

French PVCu doors were specified for each 

beach hut. 

Harmony’s Contracts Manager, Ross Bigwood, 

takes up the story: 

“As a preferred contractor of Interserve we 

were delighted to take on this project. But as 

the main focus of our business is aluminium, 

and PVCu was specified, we had to do our 

homework as to what brand of doors to use. 

“After some extensive research we found 

that the excellent thermal efficiency offered 

by Liniar profiles, coupled with the highly 

competitive price, made it the obvious choice. 

“Our fitters loved the product. The French doors 

were simple to install and we couldn’t have 

asked for better usability and workability. The 

superior thermal efficiency provided by the 

Liniar profile was vital for the location of the 

beach huts as they are designed to be in use 

throughout the year.” 

Harmony began work on-site in January with 

a tight deadline to have all 144 beach huts 

fitted out before the Easter Bank Holiday – and 

despite some inevitable delays caused by 

the weather, the assignment was completed 

ahead of schedule. 

Once all of the doors had been fitted, timber 

shutters were installed to provide protection 

painted in 15 different shades of blue.

ModLok Patio Door 

As with the window system, the Liniar 

sliding patio door was designed from 

scratch to take advantage of the very 

latest technology, and has been cyclic 

tested by Liniar’s in-house robot to 

provide assurance that it’s built to last. 


The Liniar patio door features the patented ModLok 

system, a combined reinforcement and multi-point 

locking system developed in conjunction with leading 

lock manufacturers. In addition, all external sliders feature 

multiple anti-lift properties to combat would-be intruders. 

Unique ‘air glide’ system 

Other patio doors operate on a four-wheel steel opening 

system. The Liniar patio features a unique eight-wheel 

acetal system, providing stability, durability and smooth, 

silent operation. 

Self-cleaning track 

One of the reasons other patio doors are hard to open 

is when dirt and mud fall into the track. The Liniar patio 

features built-in brushes that sweep the track clean every 

time the door is opened. 

Attractive 

With ultra-slim sculptured sightlines, no unsightly crash 

stops and a built-in decelerator, the Liniar patio door is 

one of the most attractive on the market.

Case Study - Patio Doors 

Burglars fail to beat Liniar ModLok Patio doors 

Patio doors are often considered the weakest 

point of access to a property, but a West Yorkshire 

fabricator’s faith in the security benefits of the Liniar 

ModLok system was strengthened even further 

after a failed attempt by burglars to force a set open. 

When a local building firm needed some patio doors 

for an extension they were constructing, they chose 

Liniar ModLok – not only for the stylish appearance, 

but also because of the superior security features 

they offer - and when the criminals came calling 

they more than stood up to the test, standing firm 

against the unlawful effort. 

Because the ModLok patio system combines steel 

reinforcing with a high security locking mechanism, 

utilising four hook bolts plus two shootbolts at the top 

and bottom of the sliding door, it offers far greater 

security than any other product of its type. 

The burglars, while damaging the exterior PVCu 

with their assault, completely failed to prise open 

the doors to gain access. Unfortunately for the 

homeowners, the burglars broke in to the property 

through one of two older windows instead, after 

giving up on the door. 

The patio door has since been replaced with a 

brand new ModLok and the old windows have 

also now been upgraded to Liniar - assuring the 

homeowners of future peace 

of mind.

PVCu Bi-Fold Door 

The first bespoke PVCu bi-fold to be 

launched in the UK, the Liniar bi-fold 

was designed from scratch with 

unique components. 

Standard Bi-Fold 

The advent of home designer and self-build television 

programmes created a new generation of homeowners 

wanting to open up entire walls of their homes to let in 

light and air. The very first PVCu bi-folding doors were 

made from existing window components and were 

unattractive. In addition, the nature of PVCu means it 

can contract and expand, causing challenges with the 

long-term robustness of these early doors. 

The Liniar team went back to the drawing board and 

created a bi-folding door system with brand new 

components – including a unique roller, slim hinges and 

fixings and a low threshold option. 

Since its launch in 2010 the concept has been 

reimagined to introduce the heavy duty ModLok bifold. 

ModLok Bi-Fold 

The second generation of PVCu bi-folds came with 

the Liniar ModLok bi-fold system in 2014. This design 

totally re-engineered the doors, creating an exoskeletal 

aluminium structure that combines reinforcement with a 

multi-point locking system around each pane. 

The robust nature of the ModLok bi-fold means it 

successfully passed PAS24 security testing, and has been 

cyclic tested to more than 10 times the British Standard 

without failing.

The ModLok bi-fold system was 

awarded the Queens Award for 

Enterprise in Innovation in 2017 and

– making it suitable for commercial 

applications up to 7 panes wide.

The very first bespoke designed PVCu bi-fold to be 

designed and launched in the UK, Liniar’s Standard 

bi-fold features thermally efficient profiles, slim fixings 

with hidden hinges for additional security and is 

available up to 4 panes wide – all in a wide choice of 

colours, finishes and threshold options. Bottom rolling, 

the Liniar Standard bi-fold doesn’t require additional 

strengthening of existing lintels as all the weight is on 

the bottom of the doors. 


The patented ModLok system offers a high-security 

locking mechanism with combined reinforcement, 

and offers the highest thermal efficiency of any Liniar 

PVCu bi-fold, at just 1.0 W/m²K. Its beautifully sleek 

appearance and detailed design features make it 

a popular choice for both modern and traditional 

dwellings. The ModLok bi-fold has been cyclic 

tested to more than 10 times British Standards. 

Alumina Bi-Fold 

Alumina is a ‘true’ aluminium bi-folding door system 

that encompasses the highest degree of energy 

efficiency combined with an optional ‘warm touch’ 

foiled exterior. Ideal for large scale and commercial 

applications. With PAS 24 and Secured by Design 

accreditation granted at the first attempt, the 

Alumina bi-fold also offers the ultimate in security.

Case Study - Bi-Fold Doors 

A cost effective way to add a touch of class. 

A brand new residential development of 2, 3 and 4 

bed homes in Leicestershire found a cost effective 

way of being able to offer buyers a truly unique 

selling point with the Liniar bi-fold door. 

Having already chosen Liniar windows for the 

project, the development team spotted the Liniar 

4-pane bi-fold and commented that although they 

loved it, and it would look great on the development, 

it would probably be too costly. 

Upon investigation, the original plans had been 

drawn up to include a window and a set of French 

doors at the rear of each property. It was pointed out 

that the developer would see additional cost savings 

if they were to consider a bi-folding door set instead 

– not just the French doors and the window, but also 

Even better, the reduced installation time to fit one 

product instead of two would result in a speedier 

completion time for each property. 

When the team re-worked their calculations, 

they found that the cost difference taking all of 

the above into account was only marginal. They 

agreed the benefits of being able to offer a bifolding 

door as standard in each property would 

set the development apart from others and provide 

additional value to home buyers, so it was an easy 

decision to make. 

The bi-folding doors were supplied in cream PVCu 

to match with the Liniar windows on the entire 

development, and the installation went perfectly 

to plan. 

reducing costs through having just one lintel rather 

than two, in addition to the reduction in brickwork 

and plastering between the products. 

105

PVCu Bi-Fold Door Configurations 

The Liniar bi-folding door range has a wide variety 

of options when it comes to sizes and opening 

configurations – with the Standard range available 

up to 4 panes wide and the ModLok version up to 7 

panes wide. 

Our door pane numbering works like this: 

• The first number shows the number of doors in total 

within the frame. 

• The second number shows the majority of doors 

folding back to either left or right. 

• The third number shows the balance of doors 

opening in the opposite direction. 

So, a 4-3-1 bi-folding door would be four panes wide, 

with three doors folding back to one side of the 

frame, and a single opening door on the other.

Conservatory Roof 

The Liniar conservatory roof matches 

perfectly with its range of PVCu windows 

and doors - resulting one of the most 

thermally efficient conservatories in the UK. 

A touch of colour 

Liniar’s revolutionary EnergyPlus conservatory roof is 

available in a stunning range of colours from stock and 

is designed to match perfectly with the rest of the Liniar 

window and door ranges. 

Designed for today 

Our unique EnergyPlus twin-walled top caps keep 

more of the warmth inside the building, making it less 

expensive to heat. 

Liniar’s carefully engineered roof design results in no 

holes or gaps for water ingress - and the innovative 

security measures built into the Liniar roof means that it 

can’t be taken apart from the outside – making it virtually 

burglar-proof. 

Adding extra space 

From lean-to sunrooms to large Victorian garden rooms, 

each Liniar conservatory roof is designed and built to 

your exact specifications – in as little as five days from 

quote acceptance. 

Roof kits 

The Liniar conservatory roof is available to installers in 

kit format, making it simple to assemble, fit and adjust 

on-site.

Ancillaries 

Ensure a perfect match with the 

Liniar range of trims and couplings. 

Specifying a full Liniar installation 

ensures a single point of guarantee, in 

addition to colour matched products. 

Cills and reinforcements 

Liniar cills are available in five sizes along with a range of 

end caps, jointers and reinforcing. Cills are designed to 

match the Liniar suite and can be foiled to colour match 

the Liniar range of window systems. Cills are 

multi-chambered for strength. 


Liniar has a comprehensive range of frame couplers, 

which are necessary for the combination of window 

sections. We have provided tables showing the end loads 

for all Liniar couplers, which have been calculated in 

accordance with the BPF Code of Practice for the Survey 

and Installation of White High Impact PVCu WIndows. 

Trims 

Liniar foam trims are designed and manufactured at the 

same UK extrusion facility as its range of windows, doors 

and roofs – using the same high quality manufacturing 

processes and materials.

Structural Couplings 

These ‘load tables’ have been calculated in accordance with BPF Code of Practice for the Survey and Installation 

of White High Impact PVCu Windows and are only applicable for those joint profiles restrained at their centre. 

The load tables must not be applied to those joint profiles used in isolation. All structural couplings are to be 

used with the corresponding Liniar bay pole jack when used for end (axial) loadings. 

20mm must be allowed for coupling on all joints. 

PVCu Butt Joint 

The Liniar PVCu Butt Joint is not designed to take any 

end loadings.

Longest transom/mullion length - 1.8m 

Exceeding Maximum Size - 10% Rule 

Width or height of above maximum sizes may be increased by a maximum of 10% if required so 

long as the dimension perpendicular is reduced until the product maximum weight is equal or 

lower than stated above. 

150


All custom sash weight is calculated by taking the overall width and height of the sash and 

assuming it is made completely from glass. 

The calculation is as follows: 

1m 

1mm 

1m 

Calculate the glazing weight per m 2 

1mm thickness of glass weight 2.5kg/m 2 

To calculate the weight per m 2 of a glazed unit, add up the total thickness of the glass 

e.g. 8.4/14/6 = 8+6mm of glass (14mm) 

Multiply the total glass thickness by 2.5kg/m 2 

e.g. 14 x 2.5 = 35kg/m 2 

This is the glazed unit weight m 2 

The following formulas can now be used to calculate the sash weight 

Sash weight (kg) = glazing weight/m 2 (kg) x (sash width (m) x sash height (m)) 

Maximum sash weights are shown on the left hand side. 

If heavier than 4-20-4 glazing is used, or sash sizes are increased using the ‘10% rule’ it’s important 

to use the above formula to ensure maximum sash sizes are not exceeded.

Technical Information 

Wind Loading 

BS 6399-2:1997 gives dead and minimum 

recommended imposed loads for use in designing 

buildings. It applies to: 

• new buildings and new structures 

• alterations and additions to existing buildings 

and structures 

• existing construction on change of use 

For windows manufactured at an abnormally 

large size, or those, which will feature within a glass 

facade, please consult the Liniar design office for 

wind load calculations. Calculations are performed 

in accordance with BS 6399-2:1997, loading for 

buildings, code of practice for wind loads. 

CE Marking 

BS EN 14351-1:2006+A1:2010 Windows and Doors. 

Product standard and performance characteristics. 

Windows and external pedestrian doorsets 

without resistance to fire and/or smoke leakage 

characteristics. 

• CE Marking became a legal requirement on 

1st July 2013 for construction products supplied 

within the EU and the UK, including windows and 

external doorsets. 

• By affixing the CE label, a manufacturer is 

declaring conformity with all legal requirements 

applicable to its products. 

• CE Marking is a self certification scheme and 

requires minimal involvement with independent 

third parties. 

It is the responsibility of the organisation supplying 

the complete product to market to provide the CE 

certification. Responsibility to comply and provide a 

CE mark falls to the installer/organisation adding the 

glazed unit to the frame. Failure to comply may result 

in prosecution, fines and possible prison sentences. 

152

Condensation 

Water vapour is naturally present in the atmosphere. 

Natural water content is increased by normal day to 

day living – for example, activity that generates steam 

such as cooking, bathing, laundering, boiling a kettle 

and even breathing. 

The water vapour remains undetectable while floating 

in warm air – but upon contact with cold surfaces 

such as windows, mirrors and tiles, condensation 

occurs as the vapour turns into water droplets. 

Traditional house construction allowed the escape 

of this water vapour through natural ventilation, 

including open flues of coal fires, air bricks and 

ill-fitting windows and doors – however, the drive to 

conserve energy and reduce heating costs has led 

to the sealing of homes, resulting in trapped water 

vapour and increased problems with condensation. 

With Liniar’s highly energy efficient windows and 

doors, condensation can even form on the outside 

face of a double glazed unit, due to the external 

surface being much colder than the inside. Certain 

elevations of property can be more susceptible to 

condensation e.g. north facing buildings. 

Survey and Installation 

Liniar strongly recommends that all installations 

comply with the code of practice for installation of 

PVCu window and door sets. 

BS8213 gives recommendations for the surveying 

and installation of non-load bearing windows and 

external doorsets of any material, to be installed 

vertically into the external face of buildings. It gives 

guidance on the good practices necessary for the 

successful surveying and installation of windows and 

external doorsets in both new build and replacement 

situations. It is primarily aimed at installations in 

dwellings but much of the guidance given is relevant 

to other types of installations. 

For more information refer to BS 8213-4:2007. 

153


Approved Fabricators 

Liniar windows and doors are manufactured by a 

wide network of fabricators across the UK, many 

of which have gone through a stringent testing 

and validation process to become Liniar Approved 

Fabricators. 

Where a Liniar fabricator has the stamp of approval, 

you can be assured the windows and doors they 

produce: 

• Contain only Liniar supplied or approved parts 

• Use only Liniar approved manufacturing 

processes 

• Conform to the latest British Standards 

• Have been quality checked before leaving the 

factory 

• Are CE marked in accordance with the latest 

regulations. 

In addition, all Liniar Approved Fabricators have a 

clear dispute resolution process in place - giving 

customers assurance that any problems will be swiftly 

dealt with, together with the peace of mind offered by 

the Liniar 10 year profile guarantee. 

Liniar 10 Year Guarantee 

Liniar profiles are manufactured using tried and 

tested formulations from approved suppliers and will 

not warp, split or discolour for 10 years* from date of

Installer Support 

The full Liniar range has been designed to save 

time for installers, making it ideal for large scale 

commercial projects where speed is of the essence. 

Bespoke glazing platforms mean double or triple 

glazed units are fitted to the frame more effectively, 

and Liniar’s unique beading system provides a quick, 

easy and attractive finish. 

The Liniar patio can be mechanically jointed, making 

it easier to install in hard-to-reach areas, and the 

low threshold option on both the patio and bi-fold 

systems doesn’t require trench excavation, reducing 

preparation time. 

Liniar’s co-extruded gaskets ensure no draughts or 

leaks for the end user – resulting in fewer call-backs 

for installers. With guidance for on-site fitters including 

a range of installation guides and videos to ensure 

the highest quality installations, the Liniar range is 

also fully supported by an in-house technical team to 

answer any queries.

Outdoor Range 

Liniar’s outdoor range incorporates 

innovative decking kits, fencing systems 

and plastic piling. 

Decking Kits 

Liniar decking is the perfect way to transform an outdoor 

area – so choose the best quality, British-made system on 

the market. 

Well renowned for style, high quality, strength, low 

maintenance and durability, there’s a whole host of 

additional benefits to Liniar decking kits. Deckboards are 

non-slip as class 1 fire rated for safety. 

Liniar’s galvanised steel sub-frames, unparalleled in the 

market, come part assembled for an easy build. 

The only fully sculptured balustrade system on the 

market also comes pre-fabricated, meaning no more 

fiddly cutting and fitting of handrails with pickets. 

Deckboards are supplied cut to length for hassle-free 

installation. Gates are delivered complete and modular 

steps come pre-fabricated – all saving installers an 

incredible amount of time on site. 

Kits are supplied with all necessary fixings and required 

hardware to put the deck together. 

As well as saving time on installation, all of these benefits 

remove the problem of finding sufficient space on site 

for cutting and assembly, keeping mess and noise to a 

minimum. And with components available from stock, 

waiting times are kept low with standard deck kits being 

delivered in 7 - 14 working days.

Plastic Piling 

Page 178 

Fencing 

When it comes to fencing, PVCu may not be the obvious 

choice for anyone who’s used to more traditional 

materials, such as concrete and timber. But, as a growing 

number of landscapers, commercial developers and 

homeowners are discovering, it’s now the smart choice. 

Advances in technology over recent years have made 

fencing manufactured from PVCu a real alternative 

to more traditional materials – and for good reason. 

Light to carry, easy to install, weatherproof and virtually 

maintenance free, lead-free PVCu fencing from Liniar 

beats the competition hands down. 

You may be forgiven for thinking plastic fencing is 

too flexible to use as a border. However, the internal 

chambers, along with steel reinforcing within each panel 

of Liniar fencing, give it unparalleled strength, built to 

stand up to even the strongest winds and storms. 

Piling 

Plastic piling is available ex-stock in a variety of lengths 

and is manufactured under the Liniar brand in HL 

Plastics’ own state-of-the-art factory in the heart of the 

UK. Our extrusion facility in Derbyshire boasts the largest 

mixing plant in Europe and continued investment keeps 

HL Plastics and Liniar at the forefront of innovation. 

We offer a versatile range of piling systems, including the 

traditional standard pile shape that can be configured 

as ‘Z-ribbed’ (for light use) or ‘box’ (for heavier use), and 

the facility for tying back and creating 90° corners.

Case Study - Decking 

Liniar Decking Adds Glamour To Hollywood House 

When restoring a spectacular and unique 

building in the heart of the beautiful Derbyshire 

Dales into the perfect getaway for groups of up 

to 40, it’s vital that the transformation pays as 

much attention to the exterior of the property 

as the interior. 

Built in 1910 in an authentic American colonial 

architectural style by a businessman from the 

US, this magnificent property is located in the 

hamlet of Blackbrook on the edge of a World 

Heritage site. 

Splendidly restored by local entrepreneurs 

Mike and Michele Wrigley, Hollywood 

House resembles Graceland, the infamous 

home of Elvis Presley. Oozing quality and 

class throughout, all the rooms have been 

decorated to keep in with the theme of the 

name of the house. 

“We’ve styled it on ’50s Hollywood, a time 

of wonderful glamour and sophistication, 

but we’ve done it in a subtle way,” says Julia 

Lyne-Watt, who works for Mike and Michele’s 

Ashbourne-based firm PMW Property, 

specialising in commercial, residential and 

holiday lets. 

gardens that overlook the stunning Derwent 

Valley, the glamour of the outside needed to 

match the inside. 

Liniar’s quality PVCu decking was the obvious 

choice to ensure that guests would enjoy the 

same level of luxury when relaxing on the 

terrace, which boasts a plunge pool and large 

hot tub. 

“We chose the Liniar deckboards for a variety 

of reasons,” says Julia. “The main one being the 

aesthetics – the superb colour and woodgraineffect 

brings the exterior in line with the style of 

the rest of the property. 

“But there also are lots of other advantages 

to choosing it. The anti-slip surface means 

it’s safe for our guests, especially ones taking 

advantage of the hot tub and plunge pool! 

“The deckboards are also strong, durable and 

maintenance-free, meaning long term savings 

regarding time and money – no treating, 

sanding, staining or painting! 

“The decked terrace adds the final touch 

of class to what is an amazing property. We 

couldn’t be happier with the results.”

the property and to utilise the large, private

Case Study - Log Pile 

Log pile a godsend for garden rescue project 

The original timber retaining structure in the garden 

of a home in South Wales had rotted and fallen to 

pieces, meaning that the deck and garden above 

it was in serious danger of collapsing. The developer 

called in a sub-contractor to rectify the issue and 

specified Liniar log piling as the ideal product to 

term and the homeowners were delighted with 

the finished job because they look really nice too. 

They have a wood polymer composite on the front 

surface for added aesthetic appeal. I’d definitely 

use Liniar log piling again and would highly 

recommend it.” 

replace the existing wooden support. 

The Contracts Manager on the project commented: 

“Liniar log piling proved an absolute godsend! Once 

we’d removed all of the rotten wood the piling was 

nice and easy to install – much quicker than building 

a brick wall. 

“We simply dug a trench then sat the piles in 

concrete and, because they are hollow, it enabled 

us to fill them with in-situ concrete mix to create an 

incredibly sturdy structure. “As they’re plastic, they 

won’t rot like timber, so they will be there for the long

Standard Pile - Box Format 

Liniar standard piling is offered in two formats, 

with box format offering the strongest sheet pile 

configuration with the deepest profile. 

Due to its supreme strength, standard piling is 

generally used in box format for higher retained 

heights or where greater strength is required. 

Ideal for: Water and bank retention - usually at higher retained height or where higher strength is required

Case Study - Tilt & Turn Windows 

Creating a sustainable development for Leeds PFI 

The Leeds City Centre regeneration PFI project spans 

seven blocks of high-rise apartments totalling 550 

dwellings, together with almost 1,500 low-rise and 

new build houses. The project is being managed by 

developer Keepmoat. 

The project commenced in December 2013 and 

was completed in late 2015. The Liniar system was 

specified and is ideal for large-scale developments 

such as these, as explained by the Liniar fabricator in 

charge of the project: 

“The Liniar system goes through the factory much 

faster than other systems, so it’s more cost effective to 

manufacture. 

“It’s also much easier to achieve an ‘A’ rated window, 

as we have to do less to it than we would with a 

different system, such as enhanced (and more 

expensive) glazing. 

“Our installers also love installing Liniar as it’s been 

designed to be fitter-friendly – so they’re on site for 

less time overall, which helps with project completion 

Sean Corcoran, Regional Director at Keepmoat, 

commented: 

“The Leeds PFI is a major scheme for both ourselves 

and our client. 

“We are responsible for all designs on the project 

covering high rise new build and refurbishment, 

sheltered accommodation, new build housing and 

the refurbishment of varying types of non-traditional 

housing. 

“Combining the requirements of high standards 

and tight timescales has meant ensuring our 

sub-contractors have the resources and technical 

expertise required. 

“The lead-free and energy efficient aspects of the 

Liniar profile were also important to us in creating a 

sustainable development for Leeds PFI. 

“All targets have been achieved and we look forward 

to working on other schemes using Liniar profile in 

the coming years.”

Case Study - EnergyPlus 

EnergyPlus profile employed for job centre project. 

When a five storey city centre building was marked 

for conversion into flats, Liniar windows were specified 

for various reasons – with energy efficiency and ease 

of installation being big priorities. 

The developers had specified anthracite grey on 

white windows, manufactured with Liniar’s EnergyPlus 

profile, which were top hung with toughened glass. 

Pressed and vinyl coloured panels were also used for 

a contemporary finish. 

The property in question was a former job centre in 

Pontefract town centre and the busy location meant 

that scaffolding couldn’t be used to fit the windows – 

not ideal on a five storey building! 

Although the windows were fitted internally, installers 

still had to hang out of the apertures on harnesses to 

complete the job to high standards. 

Spotters were also used at ground level to let the 

fitters at the top know when any pedestrians were 

passing, so they could stop what they were doing 

until the coast was clear. 

177 windows later and the developers were 

delighted with the finished project - and the installers 

were thrilled with the windows. 

“We were very impressed with the design and the 

clever features – the multiple chambers and the 

reduction of steel requirement in particular. 

“It’s led to lots of repeat work with the same 

developers, including a post office conversion in 

Sprotbrough. 

This has been transformed into a large residential 

property and café/wine bar, utilising cream windows 

and patio doors for a stunning finish.”

they chose a window and door provider that could 

deliver high quality products with the best possible 

thermal performance. 

Set in a truly unique location overlooking the spires 

and rooftops of Alnwick to its famous Medieval 

Castle and beyond, The Limes is an impressive 

collection of more than 80 two to five bedroom 

homes, built to the highest standards in sandstone 

and heritage brick. 

window and door frame. This trapping of air inside 

the PVCu minimises the transfer of heat from 

the inside of a home to the outside, providing 

homeowners with a highly thermally efficient 

dwelling and reducing their ongoing heating bills. 

The cream frames are covered by Liniar’s 10 year 

guarantee, and match the rest of the Liniar range 

– so buyers can also add products to personalise 

their new home. For example, a fully matching Liniar 

conservatory with bi-folding doors could add extra 

space as well as a versatile garden room to enjoy 

the spectacular views. 

The window and door frames specified on The Limes 

project give a traditional twist to a contemporary 

development. 

The EnergyPlus profile used features six symmetrical 

chambers running through the inside of each 

Kirk Thompson, Construction Director for Cussins 

commented: “We’re delighted with the window 

installations at The Limes. With a project of this 

nature, the highest quality is imperative – and the 

cream windows add a luxury finish to the homes on 

the development.”

Case Study - Casement Windows & French Doors 

Cost effective and environmentally friendly 

Willmott Dixon is one of the UK’s largest privatelyowned 

development and property support 

companies, winning a Queen’s Award for Enterprise 

for Sustainable Development in 2014. 

One recent project involved a 74-bedroomed care 

home and 11 associated bungalows in Bedworth, 

Coventry. Originated by Glancy Nicholls Architects 

on behalf of their client, Housing 21, the project 

specified grey PVCu casement windows for the care 

home, to match existing aluminium features, and 

white PVCu for the bungalows, as well as requiring 

an interface with different materials, such as cedar 

boarding to be jointly designed into the window 

system. 

run smoothly, without the usual site obstacles to 

contend with. 

The project was completed on time and within 

budget, and looks set to lead to further projects 

using Liniar profile in the future. 

Matt Somers, Principal Surveyor for Willmott Dixon 

said: 

“The Liniar profile met all of the specified 

requirements. 

“Throughout the process the fabricator has been a 

delight to work with, promoting a cost effective and 

environmentally friendly option for the client which 

met all their needs.” 

The main requirements for the windows were: 

• Cost effectiveness 

• Secured by Design status 

• Low U-values 

• Overall life cyclic costs. 

An open approach combined with a superb site set 

up by the main contractor made the whole project

Specification 

Guide 

For the full Alumina range

Safe and Secure 

Alumina products include 

bespoke hardware with shootbolts, 

independently tested to PAS24, 

Part Q and Secured By Design. 

Energy Efficient 

Thanks to the innovative patented 

combined lock and thermal 

insert, ultra-low U-values can be 

achieved with ease. 

Fully tested 

All Alumina products have been 

independently tested to ensure they 

are secure, robust, durable and 

operate smoothly. 

Foiled Finishes 

Alumina products are available 

with an optional foiled finish, 

giving warmth and a beautiful 

matching appearance. 

Guaranteed 

Foiled finishes come with Liniar’s 

10 year guarantee – and when 

installed with Liniar windows, you’re 

assured of a single point of warranty. 

Reliable Supply Chain 

As they are manufactured within 

Liniar’s existing, reliable supply chain, 

Alumina products can be delivered 

together with your PVCu windows. 

2

Our mission is to be recognised as a leading 

force for quality and excellence in product 

development - fusing industry experience 

with innovation, sustainability and loyalty. 

Aluminium windows were formerly the preferred choice for many 

commercial installations, due to the structural strength and 

size they could reach. With developments in the PVCu sector, 

including ‘flush sash’ in-line frames, many developers have seen 

the benefits of using cost effective PVCu windows and doors in 

projects both large and small. 

There are still projects that require aluminium, however, and the 

Liniar design team began to address this with the launch in 2016 

of its first aluminium system: Alumina. 

The bi-folding door system spans sash heights of up to 2.5m and 

sash widths up to 1.2m, with U-values as low as 1.2 W/m²K, thanks 

to Alumina’s patented thermal lock.

Alumina doors have two distinct differences to other aluminium 

doors on the market: they have been designed with a sculptured 

shape that replicates the lines of Liniar PVCu windows; 

and they can be supplied with a foiled finish. 

Alumina product chart

As a result, projects can now achieve the best of both worlds – 

cost effective and thermally efficient PVCu windows, with large 

scale aluminium doors – for a perfect match.

Why Choose Aluminium? 

aluminium [al-yuh-min-ee-uh-m] - noun 

a light, malleable, ductile, silvery-white metallic element that resists corrosion; 

the third most abundant element in the earth’s crust (8.1 per cent), occurring 

only as a compound, principally in bauxite. 

4

High strength to weight ratio 

Aluminium is the perfect material for large 

door apertures – as one of the lightest 

engineering metals, it has a density of one 

third that of steel. 

Its strength to weight ratio is therefore far 

superior to steel, meaning aluminium 

is lighter and easier to transport and fit 

whilst retaining supreme strength for large 

glazed units. 

Ideal for commercial projects 

Larger apertures require larger windows 

and doors, and aluminium provides the 

strength and support for increasingly 

larger sizes to be specified. 

Retail outlets, restaurants and car 

showrooms are all ideal locations for 

aluminium bi-folding doors, especially 

when combined with Alumina’s low 

threshold option. 

Resists weathering 

When the surface of aluminium is exposed 

to air, a protective oxide coating forms. 

This oxide layer is corrosion resistant and 

can be further enhanced with surface 

treatments such as anodising. 

Alumina products are treated with either 

a powder coated colour, or a factoryfitted 

foiled finish, making them truly 

weatherproof and built to last. 

Aesthetically pleasing 

Due to the strength of aluminium, wider 

and taller panes of glass are achievable. 

This means a higher glazing to frame ratio, 

creating large expanses of glass for a 

cutting edge appearance. 

The uniquely sculptured frames of Alumina 

offer a perfect match to Liniar PVCu 

windows whilst allowing for greater sizes – 

offering clients the best of both worlds. 

Supreme security 

The ModLok concept, first seen in the 

Liniar patio suite and PVCu bi-fold system, 

has been carried over to the Alumina 

range, which has its own unique modular 

lock and combined thermal insert. 

Alumina products include high security 

features such as shootbolts, anti-lift 

features and anti-bump cylinders, 

achieving PAS24 accreditation with ease. 

Sustainable 

Aluminium is a good reflector of both 

visible light and heat. Furthermore, its 

recyclability is unparalleled. 

When recycled aluminium is compared 

to virgin aluminium, there is no 

degradation in properties – and recycling 

requires just 5% of the input energy 

that’s needed to produce virgin 

aluminium metal. 

5

Alumina Colour Range 

Alumina doors are supplied as standard in plain white, black or grey powder 

coated finishes. Uniquely, Alumina can also be ordered with a wide range of 

different coloured precision factory-fitted foils, on one or both faces, ensuring a 

perfect match to Liniar PVCu windows.

Why Specify Alumina? 

The only true aluminium system on the market designed to match perfectly 

with PVCu windows, Alumina also holds its own as a beautiful stand-alone 

aluminium residential, French or bi-folding door. 

8

British made 

Alumina products are designed in the heart of 

the UK by Liniar and manufactured both in-house 

and by a small handful of carefully selected 

specialist aluminium fabricators around the UK. 

Continued investment in the factory, facilities, 

research and development helps keep Liniar at 

the forefront of innovation. 

Fully accredited 

The Liniar factory is accredited with ISO 9001 for 

quality standards, and all products are subjected 

to an exhaustive testing process, both before and 

after launch. A full-sized Alumina bi-fold system 

was independently tested to PAS24, passing with 

flying colours at the first attempt and achieving 

Part Q compliance and Secured By Design status. 

Choice of thresholds 

Alumina threshold options have been designed 

in-house, including a Part M compliant low 

threshold, measuring just 23.5mm high. The 2.5m x 

1.2m aluminium sash bi-fold was found to beat the 

requirements for both air and water tightness by 

more than double the most severe pressures within 

BS6375 Part 1 – even with a low threshold. 

Best of both worlds 

The Alumina suite has been designed to match 

fully with the Liniar PVCu range of products – 

not only in its shape but also due to the foiled 

finishes available. This means your project can be 

specified with a mix of fully matching PVCu and 

aluminium products, giving a beautiful result with 

a single point of guarantee.

All custom sash weight is calculated by taking the overall width and height of the sash and 

assuming it is made completely from glass. 

The calculation is as follows: 

1m 

1mm 

1m 

Calculate the glazing weight per m 2 

1mm thickness of glass weight 2.5kg/m 2 

To calculate the weight per m 2 of a glazed unit, add up the total thickness of the glass 

e.g. 8.4/14/6 = 8+6mm of glass (14mm) 

Multiply the total glass thickness by 2.5kg/m 2 

e.g. 14 x 2.5 = 35kg/m 2 

This is the glazed unit weight m 2 

The following formulas can now be used to calculate the sash weight 

Sash weight (kg) = glazing weight/m 2 (kg) x (sash width (m) x sash height (m)) 

Any glazing combination used must not exceed the maximum sash weight of 60kg

Accreditations and Testing 

It’s important to Liniar to prove its products are backed by the highest 

standards, and an ongoing testing programme ensures that Alumina 

remain fully compliant – often ahead of legislation. 

Alumina doors have been subjected to rigorous 

testing and have been confirmed as satisfying the 

demanding requirements of PAS:24 and Secured 

by Design, for your customers’ peace of mind. 

SBD 

The innovative, patented thermal polyamide 

Secured by Design status is awarded to products 

locking mechanism included in every Alumina 

designed with exceptional security features as 

door helps with thermal efficiency and has been 

their main priority. Liniar products that qualify 

certified by independent third party testing to 

to hold this certification are tested to meet the 

meet these strict security requirements. 

requirements of the Association of Chief Police Officers, 

PAS 24 

This accreditation is part of the British Standards 

system and shows the product has been 

subjected to a series of tests, demonstrating 

enhanced security performance, air and water 

tightness and wind loading to BS6375. 

BS 6375 

Parts 1, 2 and 3 of British Standard BS6375 are 

the requirements for performance of windows 

and doors. This includes weather performance 

testing, inclusive of wind loading, functionality 

testing and cyclic testing. 

PAS:24 & Part Q 

Part Q regulations introduced in 2015, state that all new ground floor dwellings and flats, together with new 

extensions, must meet strict criteria: “provision must be made to resist unauthorised access to any dwelling. 

In essence, doors must be “manufactured to a design that has been shown by test to meet the security 

requirements of British Standards PAS:24:2012” – so as the Alumina door range has already been accredited with 

this standard, they are fully Part Q compliant. 

Quality assured 

All of Liniar’s operations have been assessed by the British Standards Institute and confirmed to meet the 

exacting requirements of ISO:9001, so you can be assured that your foiled pre-fabricated Alumina doors will be 

manufactured to the highest standards. 

12

Weather Performance 

The Alumina bi-folding door from Liniar has been tested at its maximum door size with a thermally broken low 

threshold, achieving incredible results. 

The 2.5m x 1.2m aluminium sash bi-fold was found to beat the minimum requirements for both air and water 

tightness by more than double the most severe pressures within BS6375 Part 1 – even with a low threshold; unusual 

for a bi-fold of this size. 

Liniar classes the following as “severe weather 

performance:” 

When an installation falls within the category of 

“severe“, Liniar reccommends: 

• Coastal locations (100m above sea level) 

• Exposed locations (long stretches of open 

level country) 

• Open out only door configurations 

• Rebated frame threshold (ABF091) 

• Consult Liniar technical/design & development 

for enhanced gasket configurations. 

Thermal Performance 

Alumina bi-folds can achieve a U-value as low as 1.2 W/m²K with triple glazing. 

Other combinations of glazing can be used – please see table below for an indication of the U-values achievable

Case Study - Alumina Bi-Fold Door 

Alumina and PVCu - a perfect match 

A property renovation in Essex was the perfect 

opportunity to showcase the perfect match between 

Liniar PVCu windows and the Alumina aluminium 

bi-folding door. 

Having chosen replacement casement windows 

and residential doors in Irish Oak when they first 

moved into the property, the homeowners had 

also applied for planning permission to build an 

extension. 

The original requirement was for large French doors 

with sidelights, as the belief was that PVCu bi-folds 

would not allow for wide panes of glass. However, 

when the installer spotted the Alumina bi-fold, with its 

matching sculptured beads, he knew it was ideal for 

the project. 

A true aluminium bi-folding system, Alumina also 

offered great thermal efficiency, thanks to its 

innovative thermal lock – and as it could uniquely 

be foiled to match the window system, the whole 

project would benefit from seamless aesthetics. 

The homeowner agreed immediately, and ordered 

a three-pane Alumina bi-fold with Irish Oak foiled 

The installer commented: 

“I found the Alumina bi-fold very straightforward to 

install. It compares very well with other bi-folds I’ve 

fitted, and the fact it comes from a trusted systems 

house gives me confidence that it’s been properly 

tested and won’t cause me any issues. 

“Alumina is extremely well designed, with finishing 

touches that make it stand out, such as the 

innovative folding keys which greatly reduce the 

possibility of damaging the doors if left in situ. And 

the fact it’s foiled and sculptured to match the Liniar 

window suite gives it a distinct advantage over other 

bi-folds!” 

The homeowners agreed: 

“We weren’t sure about a bi-fold door at first – but as 

our installer had made such a fantastic job of our 

windows and doors, we trusted him completely. As 

soon as he showed us Alumina, with its low U-value 

and matching Irish Oak finish, we were sold! 

“We’ve had lots of compliments from visitors as the 

Alumina bi-folding doors look amazing.” 

exterior and white powder coated interior.

Alumina Door Configurations 

The Alumina door range has a wide variety of options 

when it comes to sizes and opening configurations – 

available from 1 to 7 panes wide. 

Our door pane numbering works like this: 

• The first number shows the number of doors in total 

within the frame. 

• The second number shows the majority of doors 

folding back to either left or right. 

• The third number shows the balance of doors 

opening in the opposite direction. 

So, a 4-3-1 bi-folding door would be four panes wide, 

with three doors folding back to one side of the frame, 

and a single opening door on the other.
