Design. Innovation. Stability.

In this premium line, we have combined our many years of experience in the development of profiles: technology is combined with timeless elegance. Greta®Fenster combines the advantages of PVC window profiles with environmental characteristics. This profile system is made as environmentally friendly as possible: the PVC used is 100% supplied from used windows and production residues. Greta®Fenster represents the best insulation performance at the level of a passive house. The natural and modern texture of concrete turns your window into an inspiring design object: complement the living space and facade with clear and minimalist window profiles.

Style is the one that shows character: RealMaterial by Greta®Fenster are inspiring high—quality surfaces.

In addition to its unique appearance, Greta®Fenster offers tactile sensations. With modern production processes, it is impossible to obtain absolutely smooth surfaces from recycled PVC. We use a unique texture to offer a modern profile with a concrete look. This is a trend that is beginning to take hold in the production of door panels, floor coverings and ceramics. The rough surface of the concrete gives a clear and minimalistic look.

Greta®Fenster combines the needs of humans and the environment

Trees are not cut down for its production. We are fully committed to recycled PVC obtained from production waste and used windows. This plastic can be completely recycled up to seven times.
