A slim-line alumnium bifolding door full of innovation and engineering expertise from the original inventor of the modern glass bifolding door.

With a building depth of 67 mm, maximum panel width of 1 m and maximum height of 3 m, the 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. Its shape helps to keep profiles extremely slim – even when using large and heavy panels. It also houses the locking mechanism and fittings, and guarantees perfect insulation.
