Comp Door are one of the UK’s most respected composite door suppliers. Each product is designed, engineered and then quality-tested at their impressive factory just down the M6 in Newcastle-under-Lyme.
They’re specialists, they only study and manufacture composite doors. The market is full of generalist manufacturers, but everything Comp Door do, from the machinery they use to the materials they source, are all chosen with creating the best composite door in mind.
In the past 5+ years they’ve really risen to the top of the market in the UK, noting the popularity of composite doors as a long-term alternative to traditional wooden doors, but equally innovating to improve an already excellent product further. They are trend setters, stay ahead of the curve with new products, and are regularly adapting their range to suit the market and its demands.
Unlike foam-filled composite doors, every Comp Door is built around a 48mm cross-laminated Albasia Falcata timber core. This gives the door exceptional structural rigidity, making it far harder to force open, and giving you a door that genuinely feels as secure as it looks.
Pick up your door handle and you'll immediately notice the difference. That solid timber core gives each Comp Door a weight and solidity that foam-filled alternatives simply cannot replicate. It's the kind of quality that's hard to describe until you've experienced it for yourself, making it an excellent choice for your new front door.
Every Comp Door comes equipped as standard with an ABS anti-snap diamond grade cylinder lock, and is fully compliant with PAS-24 security standards using the latest multi-latch deadbolt auto-fire slam lock. The moment you pull the door shut, heavy-duty deadbolts automatically engage into the frame, providing complete, effortless security without lifting a finger.
With over 250 colour combinations available inside and out, a wide range of glazing designs, and a carefully curated range of hardware options, you can design a door that's completely your own. Dual-colour options let you choose a completely different shade inside and out for a truly bespoke, personalised finish.
Comp Door's reputation as innovators who raise industry standards is evidenced by the feat they achieved in becoming the first to manufacture a solid-core composite door with U-values of 1.4 W/m²K, fully complying with strict Part L Building Regulations.
The Albasia Falcata hardwood at the heart of every Comp Door is one of the fastest-growing sustainable hardwoods in the world. As a natural material, the core actively captures and locks in carbon throughout its life, and at the end of its lifespan it is entirely recyclable, making it far more environmentally responsible than synthetic foam-filled alternatives.
Colours
Comp Door offer one of the largest colour palettes available from any composite door supplier in the UK, with over 250 colour combinations in total. From timeless classics like White and Black, through to popular contemporary shades like Anthracite Grey, Agate Grey, Chartwell Green, Slate Grey, French Grey, Pebble Grey, Duck Egg Blue and Creme Weiss, there's a shade to suit every home and every taste. Dual-colour options are available too, so your door can look entirely different inside and out.
Glazing
You can choose a door style with decorative glazing to add a personal touch, as well as a bit of natural light, to your home. Choose from a wide range of decorative glass designs, from simple, clean panels that suit contemporary homes, to intricate designs that complement period properties beautifully. All glass units are double-glazed as standard, with upgrade options available to suit your requirements. Side panels are also available on selected styles for even more natural light.
Security
Every Comp Door composite door is certified to PAS-24 security standards, one of the UK's toughest benchmarks for external doors. The solid Albasia Falcata timber core itself plays a crucial role, making the door significantly harder to breach than any foam-filled alternative.
Add in the ABS anti-snap diamond grade cylinder lock as standard, which provides maximum resistance to forced entry, and the innovative auto-fire slam lock with multi-deadbolt technology that automatically engages the moment the door closes, and you have a front door that offers genuinely complete peace of mind for you and your family.

INNOVATORS
At the heart of every Comp Door is a 48mm solid timber core, constructed from a premium cross-laminated hardwood. Most composite doors on the market use a foam-filled core, which is a reasonable option, but if you want the very best in feel, performance and security, timber is the pick.
Comp Door's solid core makes their doors exceptionally robust, and you feel that the moment you open one. There's a reassuring weight to it, a satisfying, solid feel that immediately tells you this is a quality door built to last.
The door is wrapped in Comp Door's proprietary CoolSkin outer layer, engineered to withstand extreme shifting temperatures, protecting the door from solar heat gain and ensuring the colour won't chip or flake. As a result, these doors successfully retain all the warmth and character of a traditional timber door, with none of the upkeep. You won't have to spend weekends repainting or sanding, just the occasional clean with a damp cloth to keep it looking its best.
Comp Door offer a wide range of different styles, from classic traditional designs through to sleek, modern composite doors with clean flush panels and modern glazing options. Whatever your home looks like, there's a Comp Door to suit it perfectly.
