Why Choose a Solidcore Composite Door?
Our composite doors are engineered from carefully selected materials. The Solidcore range is built around a dense, solid core β no hollow sections β with an insulating layer, all wrapped in tough Glass Reinforced Plastic (GRP) and uPVC. That solid-core construction is what makes the door so rigid, secure and quiet, while the GRP skin shrugs off the British weather without warping, cracking or fading.
Aesthetic design: graceful styling and elegant finishes that lift your home’s kerb appeal and make a lasting impression.
Superior security: a solid core plus multi-point locking provides a strong barrier against intruders.
Energy efficiency: the insulating core creates an airtight seal that minimises heat transfer for a warmer, more efficient home.
Durability beyond compare: unlike traditional timber, composite doors won’t warp, crack or fade, keeping their looks for years.
Minimal maintenance: no constant upkeep β no repainting or repairs, just an occasional wipe down.

Composite Door FAQs
What is a Solidcore composite door?
Solidcore is the composite door range we fit β built around a solid core rather than hollow sections, which makes the door more rigid, more secure and better at keeping heat in. It’s finished in tough GRP for a woodgrain or smooth look that won’t warp or fade.
How long do composite doors last?
A quality composite door, properly fitted, will typically last 30 years or more. The GRP outer skin won’t warp, crack or fade, and it needs only an occasional wipe down.
Are composite doors more secure than uPVC?
Composite doors are generally the stronger option β their solid, layered construction plus multi-point locking gives excellent resistance to forced entry, all fitted to recognised industry standards.
What colours and styles do composite doors come in?
A huge range β from White, Cream and Anthracite Grey to Chartwell Green, Rich Red and woodgrain finishes like Rosewood and Golden Oak β plus a choice of glazing designs and hardware to match your home.
