PVC is the Finstral material par excellence. Hard PVC has been at the heart of all Finstral windows for fifty years now, because it provides excellent insulation, can easily be welded for optimum impermeability, is extremely durable and is 100 percent recyclable. PVC gives superb weather resistance on the outside, while on the room side it is easy to maintain and use – and offers numerous design possibilities both inside and out. The embossed and satin-finished surfaces, only available from Finstral, are particularly special: instead of films being glued on, the textures are directly embossed into the material. This hardens and compacts the surface and makes it more dirt-resistant. From the mixing of the PVC granulate and extrusion of the solid-coloured PVC profiles to the high-quality surface finishing, Finstral undertakes every step of the process and can thus guarantee fully consistent quality.
