Super Sized, Singular and High Performance Openings

The new AMBIAL folding door creates a full opening to the outdoor, allowing to enjoy a panoramic view, letting natural light flowing in.


High performance. AMBIAL, the folding sliding door, can accommodate up to 10 leaves, each with a maximum height of 3 m and a maximum width of 1.2 m, allowing an opening 12 m wide. Each leaf, supported by exclusive Technal tracks, can bear a weight of up to 15 kg whilst providing high thermal performances, water and wind resistance.


Sleek design. The finishes have been carefully designed down to the finest detail to offer visual

harmony in both closed and open position. The profiles are flush and the visible elements are subtle and wellbalanced. The screws are concealed with black capsto ensure the homogeneity of the frame when open.


Wide selection of configurations. Open-in, open-out, central or side opening configurations, AMBIAL can be adapted to meet all requirements and encourages architectural creativity: villas, architect built houses, house extensions, hotel or restaurant terraces...
