The folding door system with thermal break allows you to create large passages.
The system is built up using a frame in which moveable parts or elements are placed in such a way that it is possible to fold the elements to the left or right.
These elements or sashes are supported and hinged to a mullion.
At the bottom the mullion is supported by a roller mechanism which slides along the sill profile while at the top, the mullion is guided by another roller mechanism.
