What is the Clima63 door and why is it perfect for your new home?

Congratulations on your new home! Now it’s time to make it truly yours. One of the most important choices you’ll make is your front door. It’s the first thing people see and it plays a big role in keeping your home warm, safe and stylish. That’s where the Hörmann Clima63 composite door comes in.

What makes the Clima63 different?

The Clima63 isn’t just another composite door, it’s designed to give you style, security and energy savings all in one. With a 63mm thick insulated slab and triple-glazed glass, it keeps the heat in and the cold out achieving a U-value under 1 W/m²K for excellent energy efficiency and lower heating bills. It’s also built to meet the Future Homes Standard 2025, so your home is ready for tomorrow.

Made in the UK using sustainable processes, the Clima63 is as kind to the planet as it is to your home. And when it comes to security you can feel confident knowing it includes multi-point locking, a 3-star security cylinder and is Secured by Design accredited, the police-approved standard for protecting your home.

How does it compare to other composite doors?

Most composite doors on the market like Hörmann Truedor’s Classic44 range are around 44mm thick and use double glazing. The Clima63 takes things further with a 63mm insulated slab, triple glazing and a steel-free thermally insulated frame that’s 30% more efficient than traditional designs.

It also includes a triple seal system for maximum draught protection. This means the Clima63 offers better insulation, improved security and performance that meets upcoming standards making it the smart choice for modern homeowners.

How much energy could a Clima63 door save you?

Upgrading to a Clima63 door doesn’t just make your home more comfortable it can also save you money. Thanks to its superior insulation a Clima63 door can reduce heat loss by almost half compared to a standard composite door. For a typical UK home, that means saving energy and reducing your carbon footprint. While the savings may vary, every little helps and combined with other energy-efficient choices the benefits really add up.

Is the Clima63 door future-proof for new building regulations?

Yes, the Clima63 has been designed with the Future Homes Standard 2025 in mind. With its 63mm insulated slab, triple glazing and triple seal system, the Clima63 delivers U-values under 1 W/m²K and A-rated energy performance making it one of the most thermally efficient doors available.
