Bi-fold have quickly become the new, must-have aluminum door, and it's not hard to see why. Bi-fold doors allow for uninterrupted views by simply sliding panels smoothly along the track to neatly stack to one side. The bi-fold is the ultimate way to combine indoor and outdoor living. All our Bi-fold doors are custom made to suit your requirements. That includes single or double window glazing for the energy efficient home. They vary greatly in size configurations from as small as a two panel door to a seven panel door for the ultimate statement piece. The bi-fold door features top-rolling operation for smooth, trouble-free operation whether configured for inward or outward stacking or with an odd or even number of door stiles. Tyred floor guides run effortlessly in channels neatly concealed beneath closed doors while effective Weatherseal technology and window glazing keeps wind, rain and cold air where it belongs.
