At Colin’s Sash Windows we’ve selected what we think are the best composite doors available. We stopped offering uPVC composite doors because they are prone to colour fading and warping in the hotter temperatures we experience these days. These aluminium composite front doors are a very similar price but are much better quality. If you’re looking for a secure composite back door these are your go to choice.
