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?

A: No, GRP composite doors are virtually maintenance-free. Unlike timber doors, they do not require painting, staining, or regular upkeep. The durable GRP skin resists weathering, scratches, and fading, ensuring a long-lasting and attractive finish with just occasional cleaning.

Q: How long do GRP composite doors last?

A: GRP composite doors are built to last decades with minimal upkeep. Thanks to their durable GRP skin, reinforced core, and weather-resistant design, they do not warp, crack, or fade like traditional wooden doors. With proper care, a high-quality GRP composite door can last 25 years or more, making it a long-term investment for your home.

Q: Are GRP composite doors weather-resistant?

A: Yes, these doors are designed to withstand harsh weather conditions. They feature a high-performance weather seal system, strong stainless steel hinges, and robust gaskets that prevent water ingress, ensuring long-term durability and protection against the elements.

Q: Do GRP composite doors comply with UK building regulations?

A: Yes, GRP composite doors meet all relevant UK Building Regulations, including:

  • Part L Compliance (energy efficiency)
  • Part F Compliance (ventilation where applicable)
  • Part Q Compliance (security standards for new builds)

Q: Can I install a smart lock on a GRP composite door?

A: Yes, GRP composite doors are Kubu smart-ready, meaning they can integrate with the Kubu smart lock system. This allows homeowners to monitor their door’s locking status in real-time via a smartphone app, providing enhanced security and peace of mind.
