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.
