As the name suggests, a composite door is made from different materials that are compressed and glued together under high-pressure conditions. The materials used in it has several beneficial properties and were put together to counteract the common flaws of single-material doors. That’s why it is more secured and durable, and it provides better thermal efficiency and simple maintenance.

The composite door is composed of many different materials which include:

  • PVC (Polyvinyl chloride) – PVC is a synthetic material commonly used in construction materials due to its is water-resistance and durability.
  • Wood – Composite doors exhibit a wood grain appearance; however, due to its composition, it does not fade nor rot over time.
  • Insulating foam – Using polyurethane foam creates higher thermal resistance and better insulation.
  • Steel – The uPVC waterproof frame is steel-reinforced, making it impact-proof.

Compared to other doors made from a single material, composite doors have a higher resistance to abrasion and weathering despite seasonal changes. It will not fade or discolour, thanks to its quality build. It can last up to 35 years without requiring any maintenance beyond an occasional wipe clean with a damp cloth.

  • A CFC-free insulating polyurethane (PU) foam core designed for thermal insulation
  • 2mm PVC banding at the edges with an ash-grain effect that matches the hinge and lock faceplate
  • 2mm glass-reinforced plastic (GRP) with a grained surface that helps to ensure that the skin of the door will be resistant to scratches, dents, cracks, twists, and warp
