Differences Between a Composite Door and a uPVC Door

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.


Composite Door and uPVC Door Differences

Thermal Efficiency

Whilst uPVC profiles provide good thermal benefits to homes, composite doors have the advantage with their multi-layered design. The core comprises sixteen alters of laminated veneered timber, then wrapped with GRP, uPVC and natural fibres. These materials work together to enhance the thermal performance of your home

The advanced manufacturing of composite doors makes them the stronger choice compared to uPVC. As you take in the insulating benefits of our supply, you can rely less on using your heating. By choosing to spend money on this high-quality product, you will reduce your energy bills and lower your carbon footprint.

Our products are designed to last for years to come and prevent unwanted draughts and water ingress from entering your home
