Introduction
Looking for a new front door often means wrestling with a confusing mix of terms like composite, GRP, or solid-core. So, what actually is a Comp Door?
At its simplest, it is a premium solid-core composite door built for elite security, warmth, and style. But when you choose your door from GFD Homes, it becomes much more than a standard replacement. It is a genuine structural upgrade that makes your home look sharper, feel warmer, and stay completely secure.
What’s inside it
The core of every Comp Door is a 48mm cross-laminated Albasia Falcata timber core – a lightweight but highly stable hardwood that resists the bowing, swelling and warping that affects cheaper foam-core alternatives over time. That core is then wrapped in CoolSkin technology, which reflects heat rather than absorbing it, protecting the surface from fading, cracking and thermal stress.
The TriSeal frame adds three weatherproof seals around the perimeter – an industry first. Most composite doors use one. The InvisiEdge system seals the door’s edges with a seamless colour finish, delivering up to 100% moisture resistance and protecting the timber core from water ingress.
Every door is fitted as standard with an ABS anti-snap diamond grade cylinder and a multi-latch auto-fire deadbolt that locks automatically on closing. It’s fully PAS-24 compliant.
What it looks like
Over 250 colour combinations inside and out. Styles ranging from timeless classics to clean contemporary designs. A SleekSkin finish option – the industry’s first smoother solid-core surface – for homeowners who want a more refined, less obviously composite look.
The range is broad enough to suit a red-brick semi, a rendered modern build or a traditional period property. The point is that it feels chosen, not just ordered.
What makes it different
Where Comp Door separates itself from many other composite doors is in how all of these elements work as a system. CoolSkin reduces thermal stress on the surface. The Albasia Falcata core resists movement from the inside. The TriSeal frame stops weather getting in at the edges. The auto-fire lock eliminates the security gap that opens up when a door isn’t fully engaged. InvisiEdge seals the one point all of the above can’t reach.
Every potential weak point has been addressed. That’s what makes it engineered rather than just assembled.
Kubu – peace of mind included
Kubu smart sensors come as standard on most Comp Doors, giving homeowners real-time visibility of the door’s security status. No more ‘did I lock it?’ moments. It’s practical reassurance, not a gimmick.

FAQ’s
1. What is the difference between a Comp Door and a standard GRP door? A standard GRP door is typically filled with a lightweight polyurethane foam core, which can bow under heat. A Comp Door uses a dense, 48mm cross-laminated timber core wrapped in CoolSkin technology, making it far heavier, more secure, and completely resistant to warping.
2. Is the Auto-Fire lock reliable over time? Yes. The automatic lock triggers mechanically as the door hits the frame keep. It is a highly tested, heavy-duty mechanism engineered for thousands of cycles, ensuring effortless operation without needing to lift the lever handle.
3. Does GFD Homes include the frame and hardware in the online price? Yes. Our pricing model is entirely transparent. When you use our online designer, the quote includes your custom door leaf, high-security frame, double or triple-glazed units, premium hardware, and VAT.
4. How does the InvisiEdge system protect the door? Standard composite doors often leave the raw edge of the core exposed under a thin strip of plastic. The InvisiEdge system creates a seamless, completely unified seal around the edge of the leaf, locking out 100% of moisture and protecting the solid timber interior from water damage.
