Warm thermal polyurethane foam is injected into the spaces between the other internal parts to create effective insulation and make the composite door energy efficient.

Most composite doors are designed and built using a 48mm thick solid timber core such as Comp Door doors. This core creates a robust and durable composite door, much better than most of the other doors available on the market today.

On top of all this, the multiple layers of material alongside the solid timber core actually help to make your composite door more soundproof, making sure you aren't as bothered by outside noises.

Glass Reinforced Plastic

A composite door usually features GRP, Glass Reinforced Plastic or Polyester. GRP is a fibre-reinforced polymer that is made from a plastic matrix and is then reinforced with some fine fibres of glass.

You can gain more advantages from a composite door than from one made of GRP only, thanks to the materials used in its construction. Composite doors have a solid wood core underneath a decorative layer that has the classic appearance and feel of wood but performs better.
