Insulated GRP Doors

Q: What is the Clima63 Thermal Door Range?

The Clima63 range is a new generation of highly insulated composite doors engineered for exceptional thermal performance, security, and modern design. It features a 63mm insulated door slab designed for sustainable, energy‑efficient homes.

Q: What is the Future Homes Standard?

The Future Homes Standard is a UK government initiative designed to ensure that all new homes built from 2025 produce significantly lower carbon emissions. The aim is for new homes to generate 75–80% fewer carbon emissions compared to homes built under older regulations, helping the UK move toward net-zero targets. The standard focuses heavily on improving the energy efficiency of the building fabric, including walls, roofs, windows and external doors.

Q: How does the Clima63 door meet the Future Homes Standard?

The Clima63 thermal door range has been engineered specifically for high-performance, low-energy homes. The door meets the thermal expectations of the Future Homes Standard by combining: A thick insulated door slab that significantly reduces heat transfer High-performance thermal core materials to improve insulation Thermally broken frame construction to prevent heat loss through the frame Advanced weather seals and airtight detailing to minimise drafts Low overall U-values designed to meet or exceed the ~1.0 W/m²K benchmark Together, these features allow the Clima63 door to deliver the thermal efficiency required for next-generation housing regulations.

Q: How energy efficient are Clima63 GRP doors?

Clima63 doors achieve a U‑Value of less than 1 W/m²K and an A‑Rated energy efficiency, exceeding the proposed Future Homes Standard 2025. This makes them ideal for reducing heat loss and improving overall home efficiency.

Q: Are Clima63 doors suitable for new builds and refurbishments?

Yes. IG Doors manufactures the Clima63 range for both new build and refurbishment projects, offering flexibility for developers, housing associations, and homeowners.

Q: What styles and colours are available?

The range includes panelled, cottage, and contemporary designs, along with a wide selection of classic and premium colours. This allows homeowners to customise their door to suit traditional or modern aesthetics.

Q: What is a GRP door?

A GRP door (Glass Reinforced Plastic) is a durable and energy-efficient external door made from a reinforced composite material. GRP doors are known for their strength, weather resistance, and low maintenance requirements, making them a popular choice for homes across South Wales.

Q: What materials are used in the Clima63 door construction?

Clima63 doors feature a 63mm insulated GRP (glass‑reinforced polymer) slab, triple‑glazed units, and a thermally efficient frame with a triple‑seal system for enhanced insulation and weather protection.
