Kömmerling Netherlands is strengthening its leadership role in sustainability and circularity with the introduction of new, improved life cycle assessments (LCAs) for Kömmerling K-VISION products. The LCAs were recently included in the National Environmental Database (NMD) and offer the most competitive environmental cost indicator (EQI) on the market.
Kömmerling Netherlands has always had a leading role in the development of sustainable and circular products. As a result, it appeared in 2022, as the first plastic system house, with category 1 entries in the National Environmental Database. “Since then, there has been a lot of tightening up in both European and national regulations for the preparation and processing of LCAs,” knows Jelmer Bijlsma, Manager Sustainability & Innovation. “For example, to ensure a level playing field between different frame materials and systems. Kömmerling calculated these new guidelines - along with all the developments of recent years. The result are new LCAs in which the environmental impact of K-VISION products is even more transparent.”
The National Environmental Database was set up independently by the NMD Foundation to enable the best choice in sustainable building products. The new LCAs of Kömmerling K-VISION Trend and Classic, with variants made of steel and a plastic EcoForce reinforcement, have been available in the NMD since May 7, 2025. “The latest analyses are more complete than ever and based on practical situations, where we have followed the new European and national and guidelines,” said Bijlsma. “This ensures fair and reliable comparisons between different materials.” Once again, this makes Kömmerling Netherlands the first system house with a set of Category 1 LCAs that are completely prepared according to the current rules of the game.
Thanks to years of efforts in areas such as recycling, reuse, energy conservation and transportation, the new LCAs of Kömmerling K-VISION products score better than competing materials. “Our K-VISION frames with steel have an MKI of €1.05 to €2.04/m2, while the EcoForce reinforcement made of recycled plastic offers an MKI of up to €0.58/m2,” says Bijlsma. “No other material can match that.”
Kömmerling Netherlands is proud of its ongoing commitment to sustainability and circularity, says Bijlsma. “The new LCAs for the K-VISION products are an important step forward in our mission to minimize the environmental impact of our products while providing the highest quality.
These analyses are a testament to our commitment to innovation and environmental awareness.”
For all K-VISION processors in the Netherlands
The new LCAs are representative of all official Dutch K-VISION processors affiliated with the Kiwa Covenant Circular Enterprise. An overview of these frame manufacturers can be found on the Kömmerling Netherlands website.
Kömmerling has 125 years of experience and is considered a premium window frame brand. The name stands for quality, innovation and sustainability. “Here we go beyond resounding declarations of intent,” Bijslma said. “Our ambition is to make a difference today and make the right actions and decisions for tomorrow's world.” Illustrative of ‘Today For Tomorrow’ is the focus on a closed material cycle. “We are also fully committed to renewable energy and post-consumer recycled packaging materials.”
Kömmerling Nederland is part of the German Profine Group and has been active in the Netherlands since 1969. Especially for the Dutch market the K-VISION series has been developed. K-VISION window frames are available through official partners. These professional window frame manufacturers process the frame profiles into full-fledged window frames and also take care of the assembly.
