Bringing the outside in
Answering the needs of contemporary architecture, the Concept FoldingĀ® 68 aluminium sliding folding door combines design, comfort and space efficiency. The wide range of possibilities to unfold numerous glass panes makes the borders between the interior and exterior literally disappear.
The folding principle of this high-quality bi-fold door allows you to combine thermal comfort and transparency, with the choice to open to the inside or the outside of the building. The bi-folding door is available in every colour and finish. There is the possibility of having a different colour for the interior and the exterior, to perfectly match the building.
