Composite doors are a cross between uPVC and Wooden doors offering the ease of maintenance of UPVC and the aesthetics of wood.

A quality product must be used to obtain a decent finish which should then be periodically re-applied so the door continues to fit function properly. Wood also requires protection from the sun otherwise it will fade and could shrink or crack if not treated properly.

uPVC doors are a lot easier to maintain than wood, keeping them clean can be as easy as wiping over with a sponge and hot soapy water, for more stubborn dirt a special cleaner can be used which will make the door look as if it were brand new again. A uPVC door is easier to look after than wood, but neither offers the convenience of a composite door.
