Express yourself by adding a splash of colour!

Along with the traditional white our casement windows are available in any RAL or Farrow & Ball colour. We’ve got lots of coloured uPVC windows for you to choose from. Grey uPVC windows are very popular especially Anthracite grey windows. Houses with Anthracite grey windows tend to look very good. The same is true with another of our bestselling colours – black uPVC windows.

You can also choose from our woodgrain colour selection. The foiled finishes are so fine that it`s almost impossible to distinguish them from the real thing. Specify dual colour if you want to enjoy the brightness of white on the inside frame faces and a striking colour finish on the outside.

Our range proves that quality and beauty belong together.
