One of very few aluminium-clad timber bifolding doors — and the only one at this level of quality and performance.

The unique combiline timber-aluminium bi-folding door has a hidden aluminium frame to give it unrivalled strength, timber doors and frame cover and alumnium cladding on the exterior for minimal maintenance and long life. 

With a building depth of 86 mm and a slender sight line in the panel joint – just 143 mm – ensures maximum transparency when the door is closed, in keeping with your natural approach to living. This is thanks to the heart of the bi-folding door: the bionicTURTLE®, a multi-functional break profile that combines a range of technical details. This innovation keeps the profiles slim – even when using large and heavy panels, it also houses the locking mechanism and guarantees perfect insulation.
