Generous living space in open-plan rooms

For more than 35 years, Solarlux has stood for the outstanding quality of versatile glazing solutions for public and private spaces. The bi-folding door has been the beating heart of the international, family-owned company right from the very beginning. 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. This produces generous glass fronts that can be opened across almost 100 % while still offering maximum protection when closed.


The possibilities offered by a bi-folding door are almost limitless. It can be used as a substructure element for a glass extension that can to be almost entirely opened; employed as an entrance to a pool; or used as an alternative to a traditional patio door or window. Also suitable for public spaces, of course! Use it for your shop entrance, glaze the VIP box in your stadium, or create a facade on your balustrade – whatever you’re building, make the bi-folding door your first choice.

Maximum Creative Freedom

Inwards or outwards, folding to the left and/or to the right – Solarlux bi-folding doors offer countless opening system possibilities. The individual glass elements can be opened or closed in just a few simple steps, whilst incorporating tilt-and-turn panels and window elements can help you enjoy even more creative freedom.
