Britannic Trade Frames Ltd offers the best PVCu bi-folding door available, the Liniar bi-fold plus.
The super smooth rolling action of Liniar bi-fold doors makes them feel incredibly light – and they are engineered to give you the reassurance that they won’t warp or bend.
To make the doors easy and safe to operate for all age groups, ergonomic handles are built in to each hinged section.
Liniar bi-fold doors have the most effortless glide action on the market – our patented roller mechanism is hidden inside each door, therefore maintaining its sleek lines. When the doors are folded back, discreet magnets ensure that they will remain securely in place.
Less frame, more glass - Liniar standard bi-fold doors have ultra-slim sightlines, providing rooms with a modern, clean appearance - letting in the maximum amount of natural light.
Innovative - Slim hinges have been added, with hidden fixings inside - increasing security as it is impossible for them to be unscrewed externally.
Configurations - Liniar standard bi-fold doors are available in a range of opening configurations from 2 to 4 panes so they can be truly tailored to your requirements.
Tested - Our standard bi-fold doors have been rigorously tested to ensure that they far exceed appropriate British Standards for weather and security performance.
First, bespoke designed bi-fold - The Liniar standard bi-fold was the first bi-fold door on the market to be designed from scratch.
Customer choice - Liniar standard bi-fold doors are available with a range of additional options, from handles and hinges, to low and half thresholds.
Slim hinges have been added, with hidden fixings inside. This not only seamlessly preserves the sleek lines but increases security as it is impossible for them to be unscrewed externally.
Ideal for family homes, the Registered Design protected Liniar low-threshold option creates a seamless entrance and exit without the need for messy and expensive excavation.
An easy-access ramp, for wheelchairs and prams, can be created using an optional tray to seat the low threshold.
Measuring just 24mm at its highest point, the ultra-low Liniar threshold is available in a choice of silver or gold finish, perfectly complementing the door hardware.
