Why Choose a Composite Back Door?
If you are looking for a strong and durable back door that looks great, then our composite doors are the right doors for you. No other product is matched on performance like a composite door.
The unique composition of materials makes them able to withstand impact and harsh weather conditions without wear and tear.

Traditional uPVC back doors are notorious for being draughty and not very well insulated. AÂ thermally-efficient back door is essential to keep your energy bills minimal. Composite materials are better insulators, providing warmth and keeping your home warm throughout the winter.Â
