PVC Bi-Folding Doors

Made-toMeasure Bi-fold Doors

PVC Bi-folding Doors Go On Add the WOW factor to your home.

Imagine being able to open up an entire wall of your room, creating space and letting fresh air and natural daylight flood into your home connecting your living space with your garden in summer. Bi Fold doors let you do just that.

Whether you have a rear living room or you are building an extension with a dining kitchen, a conservatory or an orangery, bi-folding doors can provide a door that opens further than a patio or standard French doors. Liniar’s bi-folding doors were the first fully bespoke uPVC bi-folds to be designed, engineered and made in the UK – and we believe they are still the best.

Available in a wide choice of opening configurations and colours. 

Safety features include the innovative low threshold option for family-friendly and wheelchair use. What’s more, this system is combined with the best security features on the market – bringing you a modern space-saving solution for your home that will definitely give it the ‘wow’ factor.

Better for the environment

One of the most effective ways you can save energy within your home is through installing energy efficient windows, doors and roofs.

Liniar frames outperform most of the other leading brands in the UK when it comes to thermal efficiency – mainly due to our innovative uPVC multi-chambered profile design.

The thermal efficiency of a door is measured in U-values, which demonstrate how effective the door is at preventing the transfer of heat into and out of a building.

The lower the U-value, the higher the doors’ effectiveness at keeping the heat inside your home when it’s cold outside.

The standard Liniar bi-folding door range can achieve a U-value of 1.3 W/m2K when fitted with cost-effective double glazed units, which means you’ll be able to enjoy a warmer and quieter home as well as lower energy bills.

And for even greater thermal efficiency, the Liniar ModLok bi-folding range can be fitted with triple glazing, reaching an impressive U-value of 1.0 W/m2K

Bi-folding doors are becoming more popular than ever before, thanks in part to their regular appearance in television home make-over and lifestyle programmes.

Timber or aluminium are often perceived as the only materials that can be used for bi-folding doors, but doors made from lead-free PVCu can actually offer many more benefits:

• Smoother operation
• Higher thermal efficiency
• Lower maintenance
• Can perfectly match your other doors and windows

With Liniar’s foiled woodgrain-effect options, your bi-folding doors can have the appearance of timber, without the need to repaint them each year.

ModLok LogoIf you choose our flat grey frames, your bi-folding doors will rival the most contemporary aluminium range on the market, keeping your home much warmer at a more cost-effective price. And Liniar’s ‘top of the range’ ModLok™ bi-folding door offers even greater strength and rigidity, combining all of the structural benefits of an aluminium door set with the energy efficiency of PVCu.

Discover why more and more people are choosing Liniar’s bi-folding doors to add an extra dimension to their homes.

Your Home. Your Choice.

The Liniar range offers complete flexibility, whatever the room or the size of the opening you need.

Manufactured in our decorative sculptured profile, Liniar bi-folding doors are available in a wide variety of colours.

With options from two to seven panes, all with our beautiful, super-slim sightlines, you can also choose how many doors fold back to each side of the frame.

The Liniar standard bi-fold door range is available in a wide range of configurations whilst the Liniar ModLok™ bi-folding door range offers an even greater number, due to its additional strength and rigidity (see full table opposite).

A brand new concept in locking technology, ModLok™ has been developed by Liniar to enable even wider door configurations.

Combining aluminium reinforcing within the bi-fold doors and frame with a high-security locking mechanism, the Liniar ModLok™ bi-fold offers all the structural benefits of an aluminium door set combined with the thermal benefits of PVCu – bringing you the best of both worlds.

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.

Designed for living.

Liniar’s bi-folding doors are crammed full of innovative design features.

Low maintenance
With a set of Liniar bi-folding doors, you can rest assured that you won’t need to spend hours looking after them to maintain their beauty.

Our 10-year frame guarantee gives you the peace of mind that the colours won’t fade – and not only that, you won’t need to treat or paint them each year to keep them in tip-top condition.

Just an occasional wipe down with soapy water is all they need to keep them looking their best.

Family friendly
The Registered Design protected Liniar low-threshold option creates a seamless entrance and exit, making it ideal for family homes. An optional tray to seat the low threshold creates an easy-access ramp for wheelchairs and prams.

Ultra-low, the Liniar threshold measures just 24mm at its highest point, with silver or gold finish available to perfectly complement the door hardware.

Strong and secure
The shoot bolt locking mechanism designed into each Liniar bi-folding door ensures the door is bolted firmly into the stainless steel track, maximising your security. Built-in anti-lift features, anti-bump cylinders, and optional anti-snap cylinders combine to bring you peace of mind.

Liniar’s bi-folding door range is also available with ModLok™, a new concept in locking technology.

ModLok Face View LockingModLok™ 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 doors. ModLok™ also offers enhanced security features including 3 opposing hooks and 2 shoot bolts built into every master door, plus 2 anti-lift shoot bolts on every slave door.

The Liniar ModLok™ bi-fold offers all the structural benefits of an aluminium door set combined with the thermal benefits of uPVC.

We’ve added slim hinges with the fixings hidden 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 keys being left in the locks during operation – it’s often the small things that make a huge difference.
