Composite doors are made up of a variety of materials, which are fused together to create a strong and durable door. The materials used in composite doors can vary, but most commonly include:

• uPVC: This is a type of plastic that is often used in window frames and doors due to its durability and low maintenance requirements.

• Foam: A foam core is often used in composite doors to provide insulation and improve energy efficiency.

• Wood: A solid timber core is often used in composite doors to provide strength and stability. Wood is also a natural insulator, which helps to reduce heat loss.

• GRP (Glass Reinforced Plastic): This is a type of fiber-reinforced polymer made of a plastic matrix and reinforced by fine fibers of glass. GRP is often used as a veneer on the surface of composite doors to provide a durable and weather-resistant finish.

The combination of these materials ensures that composite doors are strong, durable, and energy-efficient. They are also low maintenance, requiring only occasional cleaning with a wet cloth to remove dirt. Composite doors are a popular choice for homeowners who want a door that looks great and performs well in a variety of areas.
