A Beginners Guide to Composite Doors

If you’re thinking about upgrading your front or back door, you’ve probably come across composite doors. They’re one of the most popular choices for homeowners today, and for good reasons. Strong, energy efficient, low maintenance, and stylish, composite doors are designed to solve many of the common problems people face with older timber or uPVC doors.

Find out what composite doors are, how you can benefit, and why they could be the best option for your home.

A Beginners Guide to Composite Doors

What Are Composite Doors?

Composite doors are made using a combination of materials rather than just one. Here at Britannia Windows, ours are built from a GRP (glass reinforced plastic) outer skin, giving them unbeatable durability and weather resistance, along with a special CFC free foam core to increase their strength even more, as well as an amazing level of insulation for your home.

Thanks to their layered construction, composite doors have a fantastic balance of performance, security and style.

This blend of materials means composite doors avoid the weaknesses of traditional timber doors, like warping, rotting and needing regular maintenance, and improve on the sometimes flimsy feel of basic uPVC doors.

Key Benefits of Composite Doors

1. Superior Security

Security is one of the top reasons homeowners choose composite doors. The strong core provides a solid foundation, while advanced locking systems, such as multipoint locks and anti-snap cylinders, help add extra protection against unwanted intrusions. Many composite doors are tested to meet PAS 24 security standards, giving you confidence that your home is secure.

For homeowners looking for peace of mind, a composite door is one of the most reliable options on the market.

2. Excellent Thermal Efficiency

Energy bills are a concern for most households, and doors can be a weak spot when it comes to heat loss. Composite doors are designed to provide excellent insulation, keeping warmth inside during winter and helping your home stay cooler in summer.

Our composite doors are built to achieve impressive U-values, which means they perform well in reducing heat transfer. By upgrading to a composite door, you can expect improved comfort and potentially lower energy bills.

3. Weather Resistance

Traditional timber doors can swell, shrink, or warp when exposed to rain, wind, or changing temperatures. Composite doors are built to withstand the British climate. The GRP outer skin resists moisture, so the door won’t peel, flake, or warp.

This durability ensures your door will look good and perform reliably for years without the seasonal issues that affect other materials.

4. Low Maintenance

Nobody wants to spend hours sanding, painting, or varnishing their front door. One of the biggest advantages of composite doors is how little upkeep they need. A quick wipe with soapy water is usually enough to keep them looking fresh.

Unlike timber, there’s no need for repainting or resealing. This makes composite doors an ideal choice for busy households who want a stylish entrance without the hassle of ongoing maintenance.

5. Wide Range of Styles and Finishes

Composite doors are not just practical; they also look fantastic. They’re available in a wide variety of colours, finishes, and styles to suit both traditional and modern homes.

You can choose from:

  • Classic woodgrain finishes for a traditional look.
  • Bold modern colours to make a statement.
  • Glazing options to let in natural light.
  • Custom hardware, such as handles, knockers, and letter plates.

This flexibility makes it easy to find a door that complements your property’s character while reflecting your personal style.

6. Long-Term Value

Although composite doors can cost more upfront than basic uPVC models, they offer excellent long-term value. Their strength, energy efficiency, and low maintenance mean you won’t be facing repair or replacement costs as quickly.
