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.

Composite doors don’t need repainting and the GRP skin keeps it protected against bumps and scratches. This durability will ensure that your new door stays looking good for years to come.
Style is prioritised as much as performance with our composite doors, so they will always make sure your home stands out for the right reasons.
With a beautiful range of colours including Turquoise Blue and Ruby Red, make your door perfectly fit your home and style. You can still enjoy glazed sections which will fill your home with light and thermal glass ensures the cold can’t come in.
With a 25-year structural warranty and 10-year surface warranty, Distinction composite doors will protect your home and look pristine for many years beyond this.
