Surface design

proCoverTec, 76 laminates, aluminum solutions, Kömmerling AcrylColor – countless colours for the window! Alongside wooden structures and plain colours, profine also offers window laminates with brushed metal surfaces – and in addition various solutions with aluminum shells.

With proCoverTec, we have developed an innovative surface technology for PVC-U window profiles to market maturity. It combines functionality with durability and aesthetics. proCoverTec significantly upgrades conventional windows. The surface finishing which is unique in the industry, is achieved by a new type of liquid synthetic material. It durably protects the window profile from dirt, it is weather-resistant and it gives you an elegant silk-matt finish. The range also includes four metallic colour shades. 

Kömmerling AcrylColor are profiles with a coextruded PMMA surface, a robust, homogeneous, coloured acrylic layer that is firmly bonded with the PVC-U profile. The profiles act like a protective shield and guarantee the window colour fastness for years and a high level of scratch resistance. The refined, satin appearance is extraordinarily easy to care for, weather-resistant and virtually maintenance-free. KÖMMERLING AcrylColor profiles are 100% recyclable.
