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.
Benefits of a composite door
The aesthetic appeal is what first draws people to composite doors. Your front door is often one of the first elements of your home a guest will see. It’s important that it impresses, and composite doors certainly do that. With a resistant GRP skin, the colour will never fade. These doors have the timber look with modern performance. Fine detailing adds to the authentic look.
The thermal performance of our composite doors is second to none. With a highly insulating core, your home will no longer suffer from cold spots or draughts. Whatever the weather’s doing outside, you’ll be comfortable inside with A energy rating’s achievable. This will lower your energy bills and the superb insulation will keep unwanted sound out too. Our supply of composite doors is 17% more efficient than other solid timber core composites and timber panelled doors.
With secure locks and a strong and thick door, your home is protected. Security is always a key consideration and our composite doors are both secured by design and PAS24 accredited.
These doors are extremely durable and rigid so provide more than enough protection against intrusion, the elements as well as regular wear and tear.
