A composite door is a high-performance entrance door made from a combination of materials, including a solid timber core, reinforced PVCu, insulating foam, and a durable glass-reinforced plastic (GRP) outer layer. This innovative construction combines the best properties of each material, resulting in a door that is incredibly strong, energy-efficient, and weather-resistant. Designed to replicate the look of traditional timber doors without the maintenance, composite doors offer a timeless aesthetic with modern benefits, making them a popular choice for homeowners seeking style, security, and long-lasting reliability.
