Window Expert offers a wide range of colours and realistic woodgrains for you to choose from. You have a lot of possibilities: classic White frames, Woodgrain effect finishes or some more unusual colours. There are more than 50 colours in our palette! You can choose different colours for the inside and outside, for example something striking for the exterior of the frames, but a more subtle colour for the inside, to match your interior decor. PVC frames featuring woodgrain effect finishes are almost indistinguishable from traditional timber windows but, unlike wood, these low-maintenance options require no tiresome painting.
