FAQS

Q: What is a GRP composite door?

A: A GRP (Glass Reinforced Plastic) composite door is a high-performance entrance door designed to mimic the appearance of traditional timber while offering superior durability, security, and insulation. It features a tough GRP skin, a high-density polyurethane foam core, and a reinforced frame to provide long-lasting performance with minimal maintenance.

Q: Are GRP composite doors energy efficient?

A: Yes, GRP composite doors are highly energy-efficient. They feature a high-density polyurethane foam core that significantly reduces heat loss, making them up to 20% more thermally efficient than solid timber doors. They also meet and exceed UK Building Regulations for thermal performance, with U-values that ensure excellent insulation.

Q: How secure are GRP composite doors?

A: GRP composite doors are designed for maximum security. They come with a multi-point locking system, high-security steel hooks, and reinforced door frames to prevent forced entry. The doors also include Secured by Design-certified hardware, anti-bump, anti-drill, anti-pick, and anti-snap locking cylinders for added protection.

Q: Do GRP composite doors require maintenance?
