Contact UsThe term 'composite' simply refers to something made from multiple materials, and that's exactly what makes these doors special. Unlike traditional doors made from a single material, composite doors combine several materials - including a a strong internal core (either timber or foam), and a weatherproof GRP (Glass Reinforced Plastic) outer skin. Composite doors are typically stronger, more secure, and more energy efficient than conventional single-material doors.
Our composite doors offer exceptional security, featuring multipoint locking systems, robust cores, and meeting PAS 24 certification standards. They're also Secured by Design compliant, making them one of the most secure entrance door options available.
Both options offer excellent security and thermal performance. Timber core doors, although slightly more expensive, provide traditional solid wood strength, while foam core doors offer cost-effective insulation properties.

The cost of a composite front door depends on factors like door size, chosen design, glazing type, hardware, and installation details. Prices vary based on material quality and energy efficiency ratings rather than a set figure. Investing in a well-built door with proper installation provides better insulation, security, and long-term value.
A composite front door uses multiple materials for a thicker, stronger structure that often delivers higher security, better insulation and a longer lifespan than uPVC. uPVC doors cost less, are low-maintenance and still provide solid insulation and durability. The right choice depends on how you weigh upfront cost, appearance, budget and long-term performance.
