Upvc We supply and fit, or supply if required, windows, door, patio doors and conservatories. The system we use is manufactured by Rehau and is a 70mm system. It is generally acknowledged within the industry to be one of the three market leaders. We regularly supply the above products in White, Wood Grain and Light Oak. However we can supply virtually any shade which is available. With regard to replacement windows for a patio door, residential door or any low-level glazing (below 800 in windows) we install safety glass, either laminated or toughened, conforming with the legal requirement for safety glazing.
