Rehau UPVC Windows have been leading the replacement window sector for many years now, but have been a little slow in following the lead of some of their rivals. Now they have caught up with the launch of the Rio Flush Casement UPVC Window. You can expect the same high quality construction as all the other Rehau products, just with a flush casement style. If you would like to know more call our Harleston office on 01379 854445.
