Windows recycling

Our manufacturers recycle not only old or replaced PVC-U windows, but also the valuable cutoffs and other residue that accumulate in the production of profiles and windows. The old PVC is ground, then reintroduced to the production process. Our recycled profiles can even pass through this cycle several times without risk to their quality.


Stabilized with greenline all of PVCu windows become even more environmentally friendly. They no longer need any special treatment, from mixing the compound, manufacturing the profiles and systems, right up to final recycling. Whats more, all PVCu windows made from greenline lead-free stabilized profile contribute to protecting our climate, due to the well-recognized heat insulation properties of PVCu.

With greenline principle we think ahead, create brand values and give our customers excellent opportunities on the market. The future belongs to energy-efficient window systems, lead-free stabilizers in the virgin material and sophisticated recycling concepts. Our products fulfill your most stringent requirements with respect to thermal insulation and energy efficiency. The plastic window stands for a sustainable CO2 balance

and a superior price-performance ratio coupled with a long service life. We therefore regularly exceed the requirements of specialized window manufacturers, architects, developers and end users.
