Choosing a composite door is a big decision for your home. Here are answers to some of the most common questions customers have about composite doors, glazing differences, and upgrading features.
A composite door is made from a combination of materials such as timber, uPVC, and GRP (glass reinforced plastic). This blend creates a door that’s strong, energy-efficient, and low maintenance—offering the appearance of timber with none of the drawbacks like warping or frequent repainting.
Composite doors outperform standard uPVC and timber doors in several ways: Better insulation and energy efficiency. Higher security due to multi-layered construction and advanced locking systems. Superior resistance to weather, warping, and fading. More realistic woodgrain finishes and a wider range of colour options
You can choose from a wide array of glazing styles, including clear, frosted, patterned, and decorative glass. Glazing can be added for extra light or privacy, and many styles allow you to select from multiple glass designs to match your home’s look.
Double glazing is standard and provides excellent insulation and noise reduction. Triple glazing offers even greater energy efficiency and soundproofing, which may be worth considering for draughty areas or busy streets. The right choice depends on your specific needs and budget.All glass comes as standard in double glazing. However, there is a choice to have triple glazing in your composite doors too. Our energy-efficient doors could not only reduce energy bills but also can improve sound-proofing.
