This premium line combines our many decades of experience in profile development: Technology meets timeless elegance. GretaTM combines the advantages of PVC window profiles with environmental performance. This profile system is produced in line with the highest sustainability standards: All the PVC used comes from old windows and production waste. GretaTM boasts insulation values comparable with those for passive houses. The open-pore, natural texture with a concrete look transforms windows into tactile designer objects. Round off interiors and façades with clear, minimalist window profiles.

“We see design, sustainability and high-quality lifestyle as being a whole: Greta is the window that fits into this whole.”
Till Schmiedeknecht, Co-CEO
Style means showing character: GretaTM realMaterial brings vitality and quality to surfaces.
GretaTM looks and feels unique. Recycled PVC cannot give fully smooth surfaces using modern production methods. So we have exploited these special, open-pored surface textures to create a state-of-the-art profile with a concrete look. This is a trend that can already be seen in the production of entrance door panels, floor coverings, ceramics, etc. Coarse concrete surfaces create clarity and minimalism.
Suited to any architectural style
Different kinds of architectural styles require different kinds of windows. GretaTM profiles are part of the greenEvolution flexible modular system and can be individually tailored to your project. Their slimline design enables the construction of large glass surfaces for maximum light to enhance living space quality in renovated old and modern new buildings.

PVC – The most sustainable material for windows
PVC can generally be processed with minimal energy input and is therefore ideal for recycling. PVC windows can be fully re-processed to produce new profiles without any harmful emissions.
GretaTM in comparison
GretaTM unites human and environmental needs
Production requires no tree-felling. We use 100% recycled PVC from production waste and old windows. The material can be completely recycled up to seven times. Our in-house hydroelectric power plant and production using green electricity means every GretaTM profile produced is climate-neutral.
