Our Values : Trust

As a group of companies owned and managed by Dr. Peter Mrosik, we do not think in terms of short-term gains, but rather in terms of long-term perspectives. This mindset creates stability—for employees, customers, partners, and markets.

For us, a long-term perspective means making decisions in a way that ensures the company remains strong tomorrow. It means securing and developing jobs, training young people, building expertise within the company, and nurturing partner relationships over years and decades.

Especially in an industry where windows and building solutions have an impact for decades, this long-term mindset is crucial. Anyone who works with Kömmerling should know: We take responsibility not only for the next project, but also for the future of our customers, employees, and products.

Trust requires clear rules. As an internationally active corporate group, we are committed to integrity, transparency, and legally compliant conduct. Codes of conduct, supplier requirements, complaint procedures, and whistleblower systems provide guidance and make accountability transparent.

This applies both within the company and throughout the supply chain. We want to work with partners who respect human rights, strengthen environmental standards, improve working conditions, and promote transparency. Trust is built when collaboration is fair, transparent, and focused on mutual development.

The Kömmerling brand is a promise of quality. Window manufacturers trust that our systems form the foundation for high-quality windows, doors, and sliding solutions. This trust is built on material expertise, development experience, precise production, technical documentation, testing processes, and external certifications.

For us, quality assurance does not end at the factory gate. Our responsibility as a system provider extends further: Our systems must be so well-designed that window manufacturers can reliably produce high-quality end products from them. This includes processing reliability, clear specifications, technical support, and solutions that function reliably for many years.

Ultimately, the end customer also places their trust in the brand—often indirectly. They trust that their window will provide protection, insulation, and a tight seal, look good, and retain its value over the long term. This trust from end customers is the foundation for the market success of our partner companies.

Innovation builds trust when it solves real problems and is well-developed. Kömmerling doesn’t bring new solutions to market simply because they sound novel, but because they advance the interests of customers, buildings, and markets.

Whether energy-efficient systems, sustainable material solutions, modern finishes, hybrid windows, or digital services: for us, innovation must always go hand in hand with quality and responsibility. An innovation is only a Kömmerling innovation if it works in everyday life and offers our partners a clear benefit.

Sustainability is a particularly important demonstration of trust. This is where it becomes clear whether a company truly practises responsibility or merely talks about it.

Kömmerling and profine combine sustainability with concrete measures: closed-loop material cycles, ReFrame, bio-attributed PVC, recycling activities, energy and resource efficiency, water treatment, renewable energy and certifications.

Trust is built when progress is made transparent and verifiable. That is why certifications, environmental product declarations and industry initiatives are key elements of our communication.

Many Kömmerling partnerships have grown over the years and decades. This bond is forged not only through products, but also through collaboration, openness, the transfer of expertise, and joint development.

Window manufacturers and partner companies need a system provider they can rely on—technically, economically, communicatively, and personally. That’s why we support our customers not only with high-quality systems but also with services, training, marketing support, dialogue forums, and personalized consulting.

Your success is our success. This understanding makes partnership at Kömmerling a key demonstration of trust.

Our responsibility does not end with the sale of a profile. Our systems are used to create windows that serve in buildings for decades. Afterward, the materials should be returned to the cycle and used as raw materials for new products.

This, too, is part of trust: Anyone who installs a Kömmerling system today should be able to rely on us to consider the entire product life cycle—from development through manufacturing and use to recycling.
