There are many differences between a uPVC and a composite door. Both are extremely popular door profiles amongst homeowners. Whilst both are known for their rigidity and thermal benefits, uPVC is the more affordable choice. In recent times, composite doors are becoming more popular due to their inherent strength and rigidity.

What is a Composite Door?

Composite doors combine profiles including uPVC, solid timber core, insulating foam and GRP (glass reinforced plastic). This mixture of materials gives homeowners a door that will keep them secure and insulated throughout the year. Underperforming doors may leave your home feeling cold and noisy. By investing in this door, the layers of robust materials will maintain your property at all times.

Thermal Efficiency

Whilst uPVC profiles provide good thermal benefits to homes, composite doors have the advantage with their multi-layered design.
