Crittall strengthens W20 with PAS 24 certification

Latest News Mon, Aug 24, 2026 4:01 PM

Crittall Windows has 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. This gives architects, specifiers and developers confidence when choosing steel glazing solutions.

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 within the construction sector, where security is assessed alongside thermal performance, weather resistance and sustainability. PAS24 certification also ensures compliance with Approved Document Q of the building regulations – ‘Security in Dwellings’

Crittall® W20 has been developed to retain the slim sightlines and refined appearance that have made Crittall’s steel glazing a defining architectural feature for almost two centuries. Manufactured from galvanised steel and available in a wide range of configurations and finishes, the system combines robust construction with the flexibility needed for a variety of applications.

The thermally enhanced W20 TE® variant delivers U-values as low as 1.4 W/m²K while maintaining the characteristic aesthetic associated with the Crittall name.

Russell Ager, Managing Director of Crittall Windows, said: “Steel has always been associated with strength and durability, but today's market demands independently verified performance.

“Achieving PAS 24 certification for our Crittall® W20 and W20 TE® door systems demonstrates that architects and specifiers can achieve the security standards required for modern buildings without compromising the slim profiles and design flexibility that make steel such an enduring choice.”
