Comp Door: The Ultimate Timber Core Composite Door
Choosing a new front door is about finding the perfect balance between style, security, and durability. You need a door that not only looks stunning when it’s installed but stays that way for decades, regardless of the British weather.
At KJM Group, we only work with the industry’s best. That is why we are proud to be authorised installers of Comp Door—a brand that has set a new standard for composite door engineering.
Designed from the ground up to overcome the common issues faced by older composite doors, every Comp Door features a 48mm solid timber core wrapped in advanced CoolSkin technology. This innovative coating reflects heat, ensuring your door maintains its shape and colour even in direct sunlight, eliminating the “bowing” and fading often associated with lesser brands. Combined with exceptional thermal values and high-security locking, it is the zero-compromise choice for your home.
Why Choose a Comp Door from KJM?
- 48mm Timber Core: A solid cross-laminated Albasia Falcata timber core for maximum strength (no foam!).
- CoolSkin Technology: Advanced heat-reflective skin designed to withstand extreme temperature changes without bowing or warping.
- Ultimate Security: Fitted with the premium ABS high-security cylinder and multi-point locking as standard.
- A-Rated Efficiency: Industry-leading U-values (1.4 W/m²K) to keep your hallway warm and energy bills low.
The "CoolSkin" Difference
One of the biggest issues with standard composite doors is their tendency to bow or warp when exposed to heat. Comp Door has solved this with their industry-leading CoolSkin technology. This advanced, heat-reflective outer layer minimises solar absorption, keeping the door cool to the touch. Crucially, CoolSkin is a bonded colour foil, not a painted finish. This means it is incredibly resistant to fading, chipping, or scratching—ensuring your door looks brand new for years to come, even in south-facing positions

Solid Timber Core (No Foam)
Unlike cheaper composite doors that are filled with high-density foam, every Comp Door features a premium 48mm solid timber core. This cross-laminated Albasia Falcata timber provides incredible structural integrity. When you close a Comp Door, it sounds and feels like a solid wood door—reassuringly heavy and robust—but without the maintenance associated with traditional timber.
Comp Door is beautiful and built to last, delivering market-leading U-values for high energy efficiency. The door has an industry-first TriSeal frame, offering better weatherproofing and reducing chance of drafts for a cosy home that is comfortable, safe and secure.

The best locking mechanisms
Secure Homes
Comp Doors aren’t just good at keeping the weather out—they are designed to deter even the most determined intruders. Every door is fitted with the latest multi-latch deadbolt auto-locks, a sophisticated mechanism designed to keep your front door as secure as possible. These locks are fully compliant with PAS24 standards, giving you complete peace of mind that the latches will automatically engage whenever the door is shut.
Crucially, our locks include the renowned ABS anti-snap diamond-grade cylinder. This represents the peak of modern locking technology; it is stamped with the insurance-preferred British Kitemark (KM 586153) and tested to the highest standards by the Master Locksmith Association. It actively combats lock snapping, drilling, picking, and bumping, so even the most determined burglar won’t be able to force the door open.
The inherent strength of your composite door will also keep out less sophisticated break-in attempts. Thanks to the 48mm solid timber core, Comp Doors are thick, robust, and built to withstand direct impacts. Anyone who tries to force their way in will be left frustrated, ensuring your home and belongings remain safe.

Frequently Asked Questions
How is a Comp Door different to a regular door?
A regular front door usually consists of a single material, such as timber, uPVC, or aluminium. Comp Doors, on the other hand, are comprised of multiple materials compressed together under high pressure. This includes a 48mm solid timber core and the advanced CoolSkin outer layer, creating a door that is significantly stronger and more thermally efficient than standard single-material options.
Can I choose two different colours for either side of my door?
Yes. If you would like a dual-colour composite door—for example, Anthracite Grey on the outside to boost kerb appeal and White on the inside to brighten your hallway—that is entirely possible. Struggling to choose? Read our guide on How to Choose the Right Colour for Your Composite Door.
Are composite doors high maintenance?
No, you won’t need to do much at all to maintain its looks and performance. We recommend lubricating the mechanisms twice a year and cleaning the frame with a damp cloth occasionally. Unlike timber, there is no sanding or repainting required. For more tips, read our guide on 5 Ways to Clean and Maintain Your Composite Door.
Can I get a composite stable door?
Yes, you can. We are more than happy to help you design a composite stable door (perfect for kitchens or rear entrances) and can produce them in either 50/50 or 60/40 split configurations.
What is the lifespan of a composite door?
Our composite doors are built to last. You can expect them to keep performing at a high standard for at least thirty years. This is a conservative estimate; if kept in good condition, they can last even longer.
Are Comp Doors environmentally friendly? Yes. The core of a Comp Door is made from Albasia Falcata wood.
This is a fast-growing species that can be harvested in as little as five years, making it highly sustainable compared to slower-growing hardwoods. We also rely on recycled materials throughout the construction process to minimize environmental impact.
