Barrier-Free French Door

Looking for a French door without a threshold? The Aluplast lift-and-slide door is designed to ensure maximum ease of passage for everyone, including people with reduced mobility.

The special flush floor threshold eliminates obstacles and meets the strict requirements of the DIN 18040 standard. Moreover, despite the weight of large glass panes, opening is always smooth and light.

For renovations, the Flatstep low threshold is ideal, as it is only 2 cm high and rests directly on the finished floor without needing to be recessed.
