What is a Composite Door?

A composite door is built from multiple materials layered together. These include a tough GRP outer skin, a high density foam core for excellent insulation, and a reinforced frame with multi-point locking. The result is a door that looks great, keeps warmth in, and provides solid security with minimal upkeep. We supply composite doors from leading manufacturers, including Apeer, available in over 40 designs and a full range of colours,  from anthracite grey and white to brown composite front doors and striking red composite doors.

Secure as Standard

Every composite door comes with a multi-point locking system and high security cylinder as standard, so you can feel safe in the long term.

Low Maintenance

The GRP outer skin won't warp, crack, peel, or fade. No repainting, no resealing, just an occasional wipe-down to keep it looking like new.

Energy Efficient

The high-density insulated core gives composite doors an excellent thermal performance, helping keep warmth in and cold air out.

Huge Choice of Styles

With over 40 traditional and contemporary designs and colours ranging from classic white and grey to bold red and brown composite doors, it's never been easier to find a suitable style.

Composite Door Options

Every range comes in its own choice of colours and finishes, from smooth whites and realistic woodgrain foils to powder-coated and heritage shades. Download the brochure below to see the full palette, or ask us to bring samples to your free survey.

Composite Door Features & Benefits

Our composite doors pair a reinforced, insulated core with multi-point locking and quality hardware, giving you a front door that stays secure, warm and easy to look after for years.

Multi-Point Locking

A multi-point locking system comes as standard on every composite door we fit. On our Apeer doors, the Yale mechanism engages two rollers, three hooks, two deadbolts and a latch, securing the door against the frame from top to bottom rather than at a single point.

Anti-Snap Security

Each door is fitted with a high-security anti-snap, anti-pick cylinder and meets PAS 24 enhanced security requirements. Hardened steel hinge bolts stop the door being forced or lifted off its hinges, and Secured by Design accreditation, the UK police initiative, is available when the door is ordered with laminated glass.

Reinforced Construction

Beneath a tough GRP outer skin sits a 70mm high-density polyurethane core with built-in steel and metal reinforcement, plus a vertical steel bar running the full height of the inside edge. The result is a rigid, wood-free door that resists bowing and comfortably exceeds industry-standard impact and cut-through tests.

Thermally Efficient

The insulated polyurethane core, double-rebated twin seals and triple-glazed panels keep draughts out and warmth in. Every composite door we supply achieves at least a B energy rating, and an A++ rated Apeer upgrade using Low-E glass is available if you want the highest thermal performance.

Low-Maintenance Finish

The GRP skin has a realistic woodgrain texture and a hard-wearing, automotive-grade paint finish that won’t warp, crack, peel or fade. There’s no sanding or repainting, just an occasional wipe with warm soapy water. Choose from 27 standard and premium colours, or match most RAL and BS shades.

Great experience with Osborn Glass, who I have used for many years. The windows look fantastic, and the installers were quick, courteous and incredibly neat and tidy.

I can't recommend this company enough. They are absolutely brilliant. We had a crack in our mirrored splashback and was original told by another company that it would be a really complicated and expensive job. Found Osborn glass and they quoted 4 times less and got the job done in less than an hour! Really great communciation and would highly recommend.

Osborn fitted our new front door a couple of years ago and we've been really pleased with it. But what's been even more impressive is their after sales service. Nick, the installation manager, has been brilliant with following up a minor teething problem we had and with other matters. We've recommended Osborn to friends and they've also had a similar experience to us. This is a company that in our experience does not just take the money and then leave you - they follow up and provide great customer service.

Glass was cut to size on the spot. I was also given samples to view with prices of different glass available.

I was recommended to Osborne Glass by a friend and I was delighted with them . Importantly I am thrilled with the quality of their work which has transformed my kitchen. What set them apart though was the fantastic service from Tony and his team . As well as doing a superb job they were all just so great to deal with . They would be my first choice on similar projects in the future .

I can't recommend this company enough! I had a complex mirror repair on a wardrobe door that was chipped, and I was really worried about it. The mirror had a triangle shape with diagonal edges, and I needed it to perfectly match the other mirrors on the door. I had reached out to other companies, but most told me the job was either impossible or would cost more than the wardrobe itself. Tony, the manager, was incredibly helpful on the phone, reassuring me that they could do the job and match the existing mirrors perfectly. He was very responsive to emails, and I really appreciated his attention to detail. The service was top-notch from start to finish. The guys who collected and delivered the door were not only professional but also super nice and kind. They even helped me mount the door back onto the wardrobe, which was a lovely touch. The repair was flawless, and the new mirror matches the original ones perfectly. The whole experience was seamless, and I’m beyond happy with the result. The price was very reasonable for the high-quality work provided. If you need mirror repairs, these are the guys to go to! Professional, reliable, and truly skilled. Thank you, Tony and team!
