The most popular combination of materials is GRP (Glass Reinforced Plastic) or Fibre Glass skins with a polyurethane (high-density foam) core, but really, they could be made up of any combination of materials. Increasing in popularity because of their strength is "Solid Timber Core" Composite Doors, which typically use an Engineered Wood section in place of the foam. Other materials used to create varied brands of composite door include PVCu, Polystyrene, and more

Composite Windows on the other hand only have an exceedingly small market share in the UK, although this seems to be increasing. Options here typically include Glass and Fibre Glass, Aluminium with Timber Internals and more. The idea here is often to provide a robust outer surface with a softer more natural internal finish, like timber. Composite Windows are currently paused for availability until Spring 2022

These varying materials all have their benefits, and it is important to review the options, know the construction, and talk with an experienced supplier who isn't tied to just one or two brands so you can get unbiased advice to help you make the right choice for your home. They all exist for a reason, so select the right system for you, your home and your budget
