The bi-folding door

A bi-folding door creates smooth transitions

365 days a year

Our bi-folding door offers many advantages, but the top one is undoubtedly the smooth transition it creates between the inside and the outside. With generous glass fronts that can be opened across almost 100% of their area, the bi-folding door lends living spaces a unique ambience. Unlike traditional sliding doors, which can leave a large section of the opening covered by glass even when fully open, the individual elements of the bi-folding door gather up into a slender bundle of panels to one side – thus guaranteeing unrestricted views.

The benefits of the solarlux bi-folding door

Really open up your space :

The most important feature of the bi-folding door is its accordion-like folding technique which allows it to be opened almost 100%. A bi-folding door with a width of 5 metres can be pushed together to form a bundle just 80 cm wide.

99 mm sight line in the panel joint :

When closed, the Ecoline and Highline boast incredibly slim profile sight lines of just 99 mm in 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.

Security and anti-burglary protection :

Solalrux bi-folding doors are constrcted from high-quality materials and are extremely sturdy. The Ecoline and Highline fulfil the requirements of the standard European anti-burglary protection class RC2.

Accessibility and convenience :

Solarlux bi-folding doors are extremely convenient, with accessible floor tracks available suitable for living spaces with durable stainless steel carriages and rollers.
Thermal and sound insulation
Solarlux bi-folding doors guarantees optimum thermal insulation and depending on the system and packages, can also be used for passive houses. The soundproofing classes that can be achieved with these elements guarantee a quiet living space, even in areas with heavy traffic.

Water tightness :

The “TwinX” concealed panel centring mechanism keeps the panels centrally aligned with one another, provides stability when the system is subjected to high wind loads, and ensures that the joint alignment remains even. It also ensures that the seal level remains uninterrupted throughout the system.
