Composite Door - FAQs

Most frequent questions and answers

Composite doors are stronger than uPVC doors because they’re made by combining layers of various materials in a high-pressure manufacturing process. This results in a structure stronger than the individual components.

The surface of a composite door is fibreglass moulded to resemble wood grain. This is fused to a double internal frame of uPVC and hardwood. Thermal polyurethane foam is injected into the door to form its core. The outer frame of the door is made from steel-reinforced uPVC.

UPVC doors are made by bonding vinyl polymer with chlorine to form unplasticized polyvinyl chloride. This rigid plastic is then combined with steel.

Composite door supply and installation prices average around £1,500. The cost varies depending on door size, design, colour, glazing, and hardware.

Manufacturing composite doors is more complex than making a uPVC door, and uses sturdier materials. This makes composite doors more expensive. However, they’re less costly than timber or aluminium doors, with lower maintenance costs. And a composite door is a long-term investment in your home, lasting upwards of three decades.

Unlike timber doors, the colour of a composite door will never fade. The fibreglass (glass-reinforced plastic) surface of the door is highly durable against all types of weather and UV (ultraviolet) rays from the sun. 

This reinforced plastic skin, combined with a robust door core, also ensures your composite door will stay watertight, so there’s no risk of it warping, either.

Besides front doors and regular back doors, GreenCastle supplies and installs other types of exterior composite doors designed to maximise outside views and internal light.

These doors include:

  • French doors
  • Sliding patio doors and balcony doors
  • Bifold doors.
