Sheerline Prestige Bi-Folds
Perfectly balanced secure, sustainable and stylish next generation aluminium bi-folds doors. The new Prestige bi-folds have been designed to offer the perfect balance of refined looks, exceptional thermal performance and outstanding operation.
Choose Your Style
Sheerline Prestige Bi-folds are available in the same style options as the rest of the Sheerline range – for consistent aesthetics across an installation.
Bi-folds are also available in nine powder colours, with the option of a dual colour for each. Or choose from a further three anodised finishes for the ultimate durable and stylish finish. All twelve colours are available in just 5 weeks!
Can’t find the colour that you’re looking for? We can foil wrap your bi-folds to match any RAL colour.
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.
Integral Cills & Concealed Drainage
The integral cill and ramped low threshold options also feature unique, one-piece end caps which act as frame jointers, saving time, and incorporating concealed drainage. Outer frames can also be supplied to installers as a flat pack, to make onsite assembly easier when access is difficult.
Sheerline Prestige bi-folds use the same proven clip-in beads as the rest of the Prestige range, saving time and hassle on site. Tolerance friendly manufacture and 5mm of vertical adjustment also ensures trouble-free installations.
