Bi-Fold System
This Bi-folding system includes a thermal break and is specifically designed to cover large spaces.
This system has a wide range of different configuration allowing you to have up to 14 sashes outside and inside of the opening, with either an even or odd number of sashes.
You have the possibility to input the bottom frame into the floor, making the threshold disappear. Furthermore, the rollers and wheels are well hidden giving the Bi-folds a better look.
