Kömmerling is synonymous with sustainability and the circular economy. We have a clear attitude and vision that our new brand communication conveys. Our goal: we want to make big things happen – for our customers and for the entire market.

We want to deliver the best quality windows with the smallest possible environmental footprint while showing fairness and responsibility. That’s what Kömmerling stands for.

WarmCore® is the award-winning hybrid aluminium system with thermal efficiency at it’s core. Comprising a full suite of windows, including casement and tilt & turn styles, plus single, French, sliding patio and bifold doors, the WarmCore range is an excellent choice for every project.

Built around a belief that beauty doesn’t have to compromise performance, WarmCore windows and doors combine stunning visual aesthetics with unparalleled insulation – up to 25% more thermally efficient than traditional aluminium systems.

Designed with bespoke features and a hard-wearing finish, the contemporary style of WarmCore products makes them stand out in heritage renovations, and blend seamlessly with more contemporary projects.

The Greenline range boasts 5-chambered frames and mullions, whilst the energy efficiency credentials are improved further through the adoption of 7-chambered sashes. With a distinct green core, this product system is one for today and tomorrow’s environmentally conscious trade partners, installers and consumers with both chamfered and sculptured sash and bead options.
