Can’t find the colour that you’re looking for? We can foil wrap your bi-folds to match any RAL colour. 

thermlock technology

The Prestige Bi-Fold features a Thermlock multi-chamber thermal design. These closed-cell, insulating chambers act as thermal breaks. Working in conjunction with high-performance glazing to create class-leading thermal performance. Far superior to traditional polyamide thermal breaks. 

Prestige bi-folds achieve U-Values as low as 1.4 (with double glazing) and 1.0 (with triple glazing).

Ultion Folding Key

Our Prestige bi-folds come with an Ultion 1* Plus 2* lock and handle combination and a unique folding Ultion key. This protects the frames from damage in the fold position.

With the two-star handle, the latest product from Brisant Secure, its unique seamless curves prevent burglars from ripping it from the door. The molybdenum cylinder shield protects against drilling and lock snapping. It’s also designed to last while keeping its looks.
