Incredibly slim sight lines - patented technology
With a building depth of 67 mm, maximum panel width of 1 meter and maximum height of 3 meters, the aluminium Ecoline bi-folding door system boasts an unbroken, slim sight line of 99 mm at the panel joint. 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 extremely slim – even when using large and heavy panels, it also houses the locking mechanism and guarantees perfect insulation.
