Bi Folding Doors


The strength to weight ratio of aluminium allows us to construct frames with slim profiles that look neat and tidy in appearance but allow a lot of natural light into your property. We can also create larger frames in aluminium to reduce sight lines and help you make the most of the view out of your home.

Slim Sightlines

Allstyle bifold doors are manufactured from slim thermally broken aluminium profiles which provide strength and security, allowing you to fold and slide the panels back to the left or right and open up an unobstructed wide opening to a patio, garden or outside space.
Folding doors for internal use can be specified with a low threshold or a rebated track so that two door levels can remain constant.
