The profine GmbH - International Profile Group- was formed in 2003 by consolidating the profile activities of the HT TROPLAST under one roof. The company headquarters of profine are located in Troisdorf, North-Rhine Westphalia.

The Bigger Picture

Environment Sustainability – with a clear conscience.

For us sustainability means more than just environmental protection. From our point of view sustainability means an attentive approach to market needs. With our “greenline” principle we not only think about ecology, but also about the social and economic requirements.

Energy Efficiency

PVC windows and doors noticeably reduce the global CO2 emissions due to their excellent heat insulation. We can still do better than that. Our products fulfill the highest requirements of heat insulation, energy efficiency and durability.


For our PVC we abstain from using lead as a stabiliser in the fresh material- for already more than 10 years, we have produced exclusively „greenline“ profiles with lead-free stabilisers on an environmentally friendly calcium-zinc base.


Alongside fresh PVC-U we also consistently use recycled materials – without comprising the product quality. As a founding member of the industry-wide recycling initiative Rewindo, we guarantee the reutilisation of old PVC-U windows in a closed circuit.

VinylPlus® Product Label

As part of its sustainability strategy, profine GmbH has been awarded the “VinylPlus® Product Label” following a demanding certification process.

The "VinylPlus® Product Label" is the sustainability seal for PVC building products. Products that are characterized by high performance and sustainability are easily recognized by this certificate for end customers, manufacturers and markets. The partner companies from the window construction sector can use the label to advertise profine profile systems and sheets, for example in tenders.

profine GmbH is authorised to use the VinylPlus® Product Label in the European sales region as well as for various products and systems in the area of profiles and sheets. In this first step, the label refers to the profine production sites in Berlin and Pirmasens.
