Increase Energy-Efficiency
Composite doors, like uPVC doors, offer excellent insulation properties, helping to keep your home or business premises warm during the colder months and cooler during hot spells. When you choose composite doors, you can rest assured you are making an environmentally-friendly and cost-effective door choice for your home or commercial building. Put a stop to chilly drafts entering your property and reduce heat loss by over 70%. At Instant Windows & Doors, our composite doors are installed to maintain maximum energy-efficiency.
Enjoy Superior Durability
Composite doors are highly durable and resistant to warping, cracking and fading! They are also resistant to extreme weather conditions and ensure long-lasting performance. The reason composite doors are so robust is they are made from a combination of materials, such as uPVC, wood and glass-reinforced plastic (GRP). Composite doors offer superior durability, making them a popular and practical door choice for homes and businesses of all styles and sizes.
Reduce the Need for Regular Door Maintenance
Composite doors are easy to maintain as they do not discolour, warp, rot or flake. Generally, a regular wipe with a soft cloth and warm water should keep them looking as good as new for years to come! Give your doors a longer life and make peeling a thing of the past with composite doors, installed to last.
Increase the Security of your Property
Composite doors are renowned for their robustness and high-level security features. Advanced composite door locking systems combined with multiple layers of different materials, such as uPVC, wood, and glass reinforced plastic (GRP) make them highly resistant to forced entry and make your home or business premises safer for longer. Protect your property against intruders with new composite doors.
Enhance the Appearance of your Property
One of the reasons composite doors are so popular with home and business owners across the UK is they can be customised to suit any style you want. Whether your property is designed with modern in mind or you prefer the more rustic traditional look, we tailor your composite entrance doors to complement your interior and exterior design theme and colour scheme.
Choose a colour or opt for a traditional timber effect to make your composite doors look like authentic wooden frames. The choices are endless; select the handle that best suits your taste! Monkey tail handles, mock horns, and astragal bars are just a few of the handles we stock. Our composite door installers will also present you with a range of glazing designs for partially glazed composite doors, including anything from leaded and obscured to bevelled glass!
The sky is your limit when it comes to customising your Composite doors.Composite Doors FAQs: Secure, Stylish & Energy-Efficient Entrance Solutions
A composite door is built using a combination of materials — typically a solid timber or insulating core, reinforced frame, uPVC/GRP skin and multi-layer construction. This gives it outstanding strength, security, thermal efficiency and weather resistance compared to single-material doors.
Composite doors are among the most secure options available. They come with multi-point locking systems, reinforced hinges, and laminated safety glass. Many are PAS 24 tested and can achieve Secured by Design accreditation for enhanced protection.
Yes — thanks to their insulated cores, high-quality seals and advanced glazing options, composite doors provide excellent U-values. They help reduce heat loss, cut energy bills and keep your home warm and comfortable year-round.
Composite doors are fully customisable. Choose from modern and traditional designs, solid panels or glazed styles, and a wide palette of colours and woodgrain finishes. Dual-colour options let you match your exterior and interior décor perfectly.
No — composite doors are low-maintenance. Unlike timber, they won’t warp, rot or need repainting. A quick clean with soapy water keeps them looking fresh, while their tough GRP/uPVC skin resists scratches, fading and weather damage.
Yes — all our composite door installations include a 10-year insurance-backed guarantee and manufacturer warranties on profiles, glazing and hardware. Installations are also FENSA-registered, ensuring full compliance with Building Regulations.
The cost of a composite door depends on size, design, glazing and finishes. While more expensive than uPVC, they offer superior performance, durability and long-term value. We provide free, itemised quotes and offer finance options (subject to status).
Most door replacements do not require planning permission. However, if you live in a listed building or conservation area, or if you’re altering the size of the opening, approval may be needed. We’ll advise during your survey if consent is required.
A standard composite door installation usually takes half a day to one full day. More complex projects, such as multiple doors or structural changes, may take longer. We’ll confirm your installation schedule when preparing your quote.
