Expansive glass surfaces add freedom, comfort and light to your living space. But they also increase the weight. To ensure that airy design does not make your windows difficult to operate, we develop particularly smooth running hardware – even for sliding elements weighing up to 400 kg. Thanks to our numerous innovations, design flexibility, convenience and security are no longer either-or criteria, they are the common denominator in our PORTAL sliding door solutions – from fabrication and assembly to operation.
The new HS PORTAL technology allows unrestricted opening widths of up to 12 meters and up to more than 19 meters of total width. This applies to timber, PVCu, and even complete glass structures. With hardware from SIEGENIA-AUBI there are no limits to your layout designs.
