Our industry commitment

The building sector plays a key role in climate protection - after all, it is responsible for around 37 percent of global carbon emissions (source: The 2022 Global Status Report for Buildings and Construction). Because the construction sector is one of the most emission- and resource-intensive industries, it can now also actively contribute to achieving the global climate protection goals.

As a manufacturer of plastic profile systems for windows and doors, we are making our contribution to the transformation of the industry. With our products, we provide building owners, architects and window manufacturers with energy-efficient and smart window and ventilation solutions.

Climate protection is one of the so-called megatrends in the construction and real estate industry. This is not surprising - after all, more than two thirds of the final energy consumption in an average German private house is due to heating (Umweltbundesamt, 2024). Accordingly, the legislator has strengthened energy-efficient construction and modernisation with energy saving regulations. Rising prices for oil and gas make the careful use of these energy sources even more sensible.

In particular, window systems made of polyvinyl chloride - or PVC for short - have extremely good properties when it comes to the insulating performance and higher energy efficiency of buildings. For this reason, we rely on PVC for our profile solutions. In addition, the recyclability of PVC is another advantage that we have been using at VEKA Recycling for more than 25 years.

The energy efficiency of a window is largely influenced by the profile system used. Our profile systems from VEKA and GEALAN are designed to provide excellent thermal insulation and thus help reduce heat loss.
The thermal transmittance of a profile is expressed as the U_f-value. The lower this value, the better the insulating properties of the profile. The actual U_w-value of a window results from the interaction between the profile, the glazing and the edge seal.

For example, a VEKA window profile SOFTLINE 82 MD achieves U_f-values of up to 1.0 W/(m²K), thereby providing the basis for energy‑optimized window solutions. The specific U_w-value of a window is project‑specific and depends on the selected glazing, the edge seal and the size of the element.

A window based on the GEALAN‑LINEAR profile system, for example, achieves U_w-values of up to 0.73 W/m²K*, depending on the configuration and in combination with appropriate glazing, making it one of the most energy‑efficient solutions in the GEALAN portfolio.

As a founding member, we support Rewindo as well as the voluntary commitment within VinylPlus. Through our membership in the European PVC profile manufacturers' association EPPA, we have actively supported the idea of VinylPlus.
