Our Values : Kömmerling Brand

Not just Claimed – Implemented for years

Kömmerling recognized key future topics in the industry at an early stage and consistently brought them to market. One example is greenline. At a time when sustainability had not yet achieved its current significance in public discussion more than 20 years ago, Kömmerling abandoned lead-containing stabilizers in PVC profiles and adopted calcium-zinc stabilizers instead.

What was decisive was not only the technical solution but also the attitude behind it. Kömmerling did not view this step as a niche offering but introduced it broadly across the market.

This sent a clear signal: responsibility must not only exist where it is easy to market. It must begin at the core of the product—in the formulation, the material, the manufacturing process, and the life cycle.

This mindset continues to shape Kömmerling today. Where sustainability is often discussed from a communications perspective, Kömmerling approaches it technically and systemically: through durable formulations, high recyclability, closed material loops, energy-efficient systems, and new raw-material concepts such as bio-attributed PVC.

Quality is the basis of our brand promise. Our customers must be able to rely on Kömmerling systems being technically advanced, tested, durable, and reliable to process. Quality begins with raw materials and formulations, continues through development, production, and testing, and ultimately becomes visible in the finished window.

For window fabricators, quality means dimensionally accurate systems, clear processing guidelines, high functional reliability, and the foundation for consistently high-quality end products. For end users, quality means protection, comfort, security, energy efficiency, and value retention over many years.

This is precisely how trust in the product—and trust in the brand—is created.

The Window Innovations Center and ISO 9001 certification demonstrate that quality is tested and embedded within the organization.

For Kömmerling, innovation does not mean following every trend. Innovation means developing new solutions to real challenges—with clear benefits for our customers, for the market, and for the finished building.

We develop systems, materials, surfaces, and services that support window fabricators in their daily work, simplify processing, open up new design possibilities, improve energy efficiency, and create new market opportunities. For us, innovation is only valuable when it works in everyday practice and stands the test of time.

Trust also arises from this: our partners know that Kömmerling not only meets current requirements but actively helps shape the future of window construction.

Kömmerling WarmCore demonstrates how innovation, design, energy efficiency, and material quality can be combined.

For Kömmerling, sustainability primarily means circularity, durability, energy efficiency, and the responsible use of resources. As a systems provider, we have a particularly strong lever within the circular economy. After use, PVC windows can be recovered, processed, and reused as recycled material in new profiles.

Kömmerling understood sustainability within the product from an early stage—from greenline and calcium-zinc stabilizers to ReFrame and bio-attributed PVC, through to closed material loops, Smart Design, and energy-efficient system platforms.

Sustainability creates trust when it is not merely claimed but measurably documented, implemented in products, and supported on an industrial scale.

greenline demonstrates that Kömmerling assumed responsibility for materials at an early stage.

Kömmerling ReFrame demonstrates how the circular economy becomes tangible in window profiles.

The Kömmerling Better World Foundation demonstrates that responsibility extends beyond the product itself.

For Kömmerling, trust means that people and partners can rely on us to act with a long-term perspective, responsibly, and according to our values. Employees can trust that company leadership does not think in the short term but creates perspectives. Customers and partner fabricators can trust that our products and systems deliver what they promise. Suppliers and cooperation partners can rely on dependable collaboration. End users can trust that our systems can be used to create high-quality windows that provide protection, save energy, and preserve value for many years.

Trust also arises from the fact that Kömmerling has a long history. Since 1897, the name Kömmerling has stood for entrepreneurial spirit, quality, innovation, and partnership. Customer relationships built over generations and long-term cooperation with employees and partners are only possible when people can rely on one another.

Trust is therefore not an additional communication claim. Trust is the sum of what Kömmerling must prove every day: in leadership, in the product, in partnerships, in the supply chain, in the way people are treated, and in the responsible use of resources.

The long history since 1897 demonstrates that Kömmerling builds on long-term perspectives and established partnerships.
