What is a
composite door?

A composite door is made up of a combination of materials. This means it can improve on the performance of standard uPVC and timber doors. With a rigid polymer frame and insulating foam core, the multi-layers provide barriers against the cold and severe weather. As well as their unique interior, their exterior also makes them stand out. Doors have a woodgrain effect GRP (glass reinforced plastic) skin that’s damage and impact resistant. This lets them fit in perfectly in traditional as well as modern homes.
