A composite door is a modern entrance door made from multiple materials, typically uPVC, timber, insulating foam, and a glass-reinforced plastic (GRP) outer skin. This unique construction blends the strengths of each material, resulting in a door that is exceptionally strong, secure, and thermally efficient.
With minimal maintenance, composite doors can last 30 years or more. They are built to resist warping, cracking, fading, and weather damage much better than traditional timber or uPVC doors.
Yes! Security is one of the key selling points of composite doors. Most are fitted with multi-point locking systems, anti-snap cylinders, reinforced frames, and security glazing. Look for certifications like PAS 24 and Secured by Design for extra peace of mind.
Unlike timber doors, composite doors are highly resistant to warping, twisting, and swelling due to moisture or temperature changes. Their GRP (Glass Reinforced Plastic) outer skin is also UV-stabilised, which means it resists fading even after years of sun exposure.
Composite doors are low maintenance. Clean the surface with a soft cloth and mild soapy water monthly. Lubricate locks and hinges once or twice a year. No painting, varnishing, or special treatments are needed.
Generally, composite doors are not designed to be painted because their colour is integrated into the outer GRP skin. Painting may affect the finish and potentially void warranties. If you want a new look, it’s better to order a new door in your preferred colour.
Absolutely. The insulated foam core and tight seals on composite doors deliver excellent thermal performance. They help reduce heat loss and can lower your energy bills. Look for doors with low U-values (1.0 W/m²K or less) for best results.
Composite doors come in a huge range of colours, from classic whites and woodgrains to bold reds, blues, and greys. You can choose from traditional, contemporary, cottage, and glazed styles, along with a variety of hardware finishes.
No, composite doors are often quieter than other types of doors. Their dense construction and secure seals help reduce outdoor noise, creating a quieter home environment.
Prices vary based on design, glazing, hardware, and installer, but a quality composite door typically ranges from £800 to £2,500, including fitting. While more expensive than basic uPVC doors, composite doors offer superior security, durability, and kerb appeal.
Minor issues like surface scratches or hardware problems can often be repaired. For more serious damage (such as deep dents or cracks), contact your installer or manufacturer, repairs may be covered under warranty.
Composite doors should always be installed by a professional, preferably one registered with FENSA or CERTASS. Proper installation ensures the door performs optimally for security, insulation, and weather resistance.
Most reputable manufacturers offer a 10-year warranty covering defects in materials, manufacturing, and sometimes installation. Always check the specific warranty terms before purchase.
Many composite doors are made with energy-efficient cores and recyclable uPVC components. Their long lifespan also reduces the need for replacements, minimising environmental impact.
Yes, composite doors are suitable for front, back, and side entrances. They’re ideal anywhere you need security, insulation, and weather resistance.
No, composite doors are engineered to withstand both heat and cold without swelling or sticking, unlike solid timber doors.
Yes. Fire-rated composite doors are available for specific applications, such as apartments or internal doors in multi-occupancy buildings. Always specify your needs when ordering.
Composite doors combine the best properties of uPVC, timber, and modern insulating materials, offering far greater strength, durability, and security compared to single-material doors. They outperform traditional uPVC and timber doors in nearly every category.
