Crittall Windows is adopting new Low-Earchitectural powder coatings that can significantly reduce the energy required to finish its steel windows and doors.
The company has adopted the Interpon D1036 Low-E and Interpon D2525 Low-E from AkzoNobel. The coatings offer the same performance and longevity as the established formulations, but can be cured at 150°C rather than 180°C. That 30°C reduction in curing temperature means less energy is needed during production, helping to reduce carbon emissions while improving manufacturing efficiency.
Interpon D1036 Low-E is suitable for internal and external applications, while Interpon D2525 Low-E is designed for external surfaces where enhanced durability is required, including windows, doors and building facades. Both coatings are Qualicoat certified and available in all RAL and BS colours including custom shades, giving architects and designers complete freedom over the finish.
For specifiers, choosing a product manufactured using a lower-energy coating process can contribute to reducing the embodied carbon associated with a building project, without compromising the durability or appearance of the finished steelwork.
Crittall’s steel windows are manufactured using recycled steel – a product that remains infinitely recyclable without impacting overall quality. Steel windows installed a century ago are still in use today, meaning the whole-life cycle cost of Crittall is spread across decades.
Russell Ager, Managing Director of Crittall Windows, says: “Sustainability must be about making practical changes throughout the manufacturing process, and this is a good example of that approach. By adopting a coating that cures at a significantly lower temperature, we can reduce the energy used in production while maintaining the performance, durability and finish that Crittall products are known for.
“It’s an improvement to a sustainable product made from recycled steel designed to last generations. It also gives architects and specifiers another way to make more responsible choices when developing building projects, without having to compromise on design or performance.”
Crittall Windows has also secured PAS 24:2022 certification for its Crittall W20 steel door system and thermally enhanced W20 TE variant, providing independent verification of their security performance. The achievement is proof that the systems meet one of the UK’s most widely recognised security standards for doors and windows.
PAS 24, overseen by the British Standards Institution (BSI), assesses the ability of doorsets and windows to resist the methods of attack commonly associated with opportunist burglary. Products undergo rigorous testing to demonstrate their security performance under sustained physical attack. The certification reflects the growing importance of evidence-based specification, where security is assessed alongside thermal performance, weather resistance and sustainability. www.crittall-windows.co.uk
