Bi-Fold Doors from Isis Windows
A bi-fold door, also known as bi-folding or glass sliding model, consists of a series of panels which fold and stack against the wall like a concertina. Because these models pull out from the middle, you have full access to and a complete view of what’s behind the door in a single movement. What’s more, these study solutions eliminate the ‘shuddering’ that you get with some sliding doors.
Bi-folding doors can have up to seven panels joined with hinges, attached to rollers at their top or bottom. These models also often have a ‘traffic’ panel for popping in and out so you don’t always need to open the door to its fullest extent.
