Though PVC-U windows are relatively new to the UK, REHAU (one of Europe's leading polymer producers) has been manufacturing PVC-U window systems for over 40 years. REHAU pride themselves on their stringent testing and rigorous quality control.

In addition to in-house tests, all REHAU window systems are tested by independent bodies such as the British Standards Institute (BSI) and the British Board of Agreement (BBA). REHAU`s quality control control systems meet British Standard BS 5750 part 2.

REHAU`s expertise in the field of window design and technology is based upon experience in manufacturing a vast range of polymer products from car bumpers to valves for open heart surgery! No other European manufacturer of window systems has anything like REHAU`s breadth of experience.
