Colour Palette

We have a beautiful range of colours to choose from. We have reliable classics like white and anthracite grey, woodgrain finishes for a traditional look and a selection of more unorthodox colours too. The foils are applied during the manufacturing process, so you’re guaranteed long-lasting colours that won’t fade.
That’s not all, we can also offer dual colour windows. Want a different colour on either side of the window? We’re more than happy to help. With our colour options, you can match the aesthetic of your current windows or go for something entirely new, the choice is all yours.

They’re all made to measure and can be adjusted for multiple stylish looks. Whether you live in a contemporary new-build, a heritage home or a sophisticated townhouse, we’ll help you find the best new windows.
