Bifold doors

Open – to everyone!

Maximum Opening

The special feature of bi-folding glass doors lies in the large-scale opening of rooms and façades. The zig-zag structures of the window wall elements can be folded to the side to form a narrow set of panels and thus open to almost 100%, while offering maximum protection when closed. The generous glass front is transformed into a flowing opening. Exterior and interior merge together as the user wishes.
Functionality, design wishes thanks to high-quality materials and limitless combinations make the bi-folding wall ideal for use in new builds and renovations.

Functional principle & applications

Bi-folding glass walls offer what classic sliding windows cannot: large glass fronts that can be opened almost 100% and offer maximum protection when closed. This is because, unlike the classic sliding door, the individual elements of the bi-folding wall can be folded completely to the side to form a small package.

The ability to remove limits and flexibly combine the inside and outside makes bi-folding glass wall suitable for use in all types of buildings. From private residential buildings and urban apartment blocks to gastronomy use and sports facilities: All uses benefit from the freer design of the transition area or the flexible organisation of rooms in the inside living area.

5 Questions & Answers

What is the difference between a bi-folding wall and a sliding door?
A bi-folding glass wall allows an almost complete opening by folding back the elements completely and thus a smooth transition between inside and outside, whereas with a sliding door, a part of the opening always remains blocked by overlapping door leaves.
Thermally separated frames prevent thermal bridges and ensure optimum insulation – Certain models achieve Uw values of down to 0.8 W/m²K, which qualifies them for use in passive houses.
Certified security: Many models are certified to RC2 or even RC3, which offers a high level of protection against burglary attempts. High-quality materials and security glass further increase burglar resistance.
Yes, in addition to aluminium, wood can also be used. The frame consists of an aluminium construction that is fully covered with solid wood strips on the inside and outside.
