Products available in the XTREMEDOOR range

Traditional and Contemporary GRP Composite Doors

Xtremedoor composite doors combine the classic aesthetics of timber with modern security and energy-saving benefits. Designed to enhance both traditional and contemporary homes, they offer the perfect blend of style and performance.

Built with a high-density foam core, composite doors deliver superior strength and thermal efficiency, helping to keep homes warm and energy bills down. The durable Glass Reinforced Plastic (GRP) outer skin—made from the same tough material used in wind turbines—ensures long-lasting protection against the elements. Unlike timber, composite doors require minimal upkeep—just a quick wipe with a damp cloth keeps them looking as good as new.
