In the frame: innovations in PVC window profiles


Recent developments in window profiles include a 100% recycled product in Germany – and a new cooling system that speeds up production


Window profiles are a key extruded product, as PVC windows continue to replace other materials such as wood and aluminium. This means that new designs and production methods are continually being developed. Profine of Germany has developed a window system for Lixil – a Japanese supplier of water and housing products. The sliding system is specific to the Japanese market, and forms part of Profine’s efforts to expand internationally. Lixil chose Profine as a partner because of its


Kömmerling brand, as well as the system concept of the window, it said. A demanding development process led to a specific sliding window system that has high thermal insulation – and uses a high percentage of recycled material. “The cooperation with Lixil opens up new


markets,” said Peter Mrosik, CEO of Profine. “Our partner benefits from our know-how in the devel- opment of energy-efficient window systems.”


Recycled windows The company has also supplied window frames – made completely from recycled PVC – for a building project in Germany.

The ReFrame windows have been supplied for a


children’s day-care centre in Moenchengladbach, with its project partner Rolladen Müllers. “ReFrame windows – part of our Kommerling


brand – are the first to be made entirely of recycled PVC and have the same functional properties as conventional PVC windows” said Friedhelm van den Berg, area sales manager for Germany at Profine. “They have a UV-resistant surface, good technical properties and a high thermal insulation value.” Müllers has manufactured 57 ReFrame windows and doors of the Kommerling 76 double seal system and will install them in the day-care centre. Construc- tion of the centre should be complete in the summer. A second building project – an apartment building with a daycare centre on the ground floor – will also be equipped with ReFrame window profiles. ReFrame windows are finished with Profine’s


ProCoverTec surface technology to give them a high-quality appearance. ProCoverTec also improves technical properties such as UV resist- ance and IR reflection, says Profine.


Material developments Benvic of Italy is developing a number of material grades for use in window profiles.
