The true size of a room is measured not in square meters, but in apparent spaciousness and natural daylight. Here large sliding elements play out their strengths with SIEGENIA PORTAL hardware. Because thanks to maximum product quality and innovative comfort details, extending to barrier-free solution, they are operated as lightly as a feather and securely in every size, opening type and weight class. Sometimes by pressing a button or sometimes with the SIEGENIA Comfort app. This is how PORTAL creates the space for fantastic barrier-free living and offers you the best prospects for streamline logistics and more efficiency.
