Bi-Fold Doors & Windows:

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. Whether you have a bedroom with Juliette balcony, a dining kitchen, a conservatory or an orangery, bi-folding doors can provide a stunning alternative to patio or French doors. Liniar’s bi-folding doors were the first fully bespoke PVCu 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, your Liniar bi-fold has ultra-slim sightlines, providing your room with a clean, modern appearance. Safety features include the innovative low threshold option for family friendly and wheelchair use. What’s more, the Liniar bi-fold offers high energy efficiency, 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.

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 PVCu 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 doubleglazed 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

The Liniar range offers complete flexibility, whatever the room or the size of opening you need. Manufactured in our decorative sculptured profile, Liniar bi-folding doors are available in a wide variety of colours. ith 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.
