Who or what is Rehau?

Our standard window and door range is made from the renowned REHAU engineered uPVC system. REHAU was founded in Germany back in 1948 and first entered the UK market in 1962. One of the first companies to produce and sell uPVC window and door systems in the UK, today all Rehau systems are manufactured in their state of the art plant in North Wales – successfully bringing together the best in German design with UK manufacture.

Not all uPVC windows are the same – the quality of the materials, construction, overall design, locking and weather proofing systems can vary immensely from manufacturer to manufacturer. As the established market leader in the supply of uPVC window and door systems, we’re very proud of the fact that we install Rehau windows and doors as standard at Harp. Check out our Rehau windows album on our Gallery page and see what we could do for your home!
