Sheerline Prestige Bi-Folds

Perfectly balanced secure, sustainable and stylish next-generation aluminium bi-fold doors. The new Prestige bi-folds have been designed to offer the perfect balance of refined looks, exceptional thermal performance and outstanding operation. 

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 or three anodised finishes with the option of a dual colour for each. Can’t find the colour that you’re looking for? We can foil wrap your bi-folds to match any RAL colour.

We also offer woodgrain foils that perfectly match The Residence Collection finishes, enabling seamless colour coordination between our product lines.

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).

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.
