PRESTIGE Bi-Folding Doors Ecoline/Highline

Bi-Folding Doors Ecoline/Highline 84 mm

INCREDIBLY SLIM SIGHT LINES, PATENTED TECHNOLOGY

With a building depth of 84 mm, maximum panel width of 1.1 metres and maximum height of 3.5 meters, the Highline 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.
