Vertical Windows

Vertical Windows
For homeowners seeking that traditional style you can now choose the REHAU vertical sliding window. Many believed vertical sliding windows were a thing of the past but thanks to modern design and engineering there is not a vertical alternative. Our modern vertical windows still retain all the benefits of modern uPVC windows while imitating the timeless sash design of older vertical windows.
REHAU sliding sash windows are the most authentic uPVC vertical windows available on the market in the UK. They consulted with multiple conservation bodies to find a design that is true to the characteristics of an older sash window without sacrificing the quality of modern UPVC benefits.
