Bring the outside in with our Sheerline Prestige bi-folds, creating an increased sense of space and a seamless transition between your garden and the inside of your home.
Sheerline Prestige bifold doors combine the refined architectural look of aluminium and the latest thermal and security technology.
Our Sheerline Prestige Bi-Folding doors feature a Thermlock multi-chamber thermal design. These closed-cell, insulating chambers act as thermal breaks. Working in conjunction with high-performance glazing to create a class-leading thermal performance.
Sheerline Prestige bi-folds achieve U-Values as low as 1.4 (with double glazing) and 1.0 (with triple glazing). The lower the U-value is, the better insulated the window/door is.
Our Sheerline 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.
Sheerline Prestige bi-folds are available in nine powder colours, with an option of a dual colour for each. Or choose from a further three anodised finishes for the ultimate durable and stylish finish.
