Two of FAS’s flagship fire protection products – FAS Fire Door Foam™ and FAS Fire Door Intumescent Acrylic Sealant have recently been selected for national standardisation by a leading UK housebuilder. This milestone underscores growing industry recognition of the need for reliable, tested, and installation-friendly fire door solutions across large-scale residential developments. 

 

Engineered for Safety and Simplicity

 

Both sealants have undergone rigorous testing to close gaps between fire door frames and walls, achieving compliance with BS 476 20&22:1987 and BS EN 1634-1 standards. In addition, Certifire certification by Warringtonfire reinforces their trusted fire protection performance. 

 

But performance isn’t the only priority; usability matters too. FAS worked closely with installation teams to evolve its foam product from pink to its distinctive orange, clearly distinguishing it from general-purpose alternatives. This also inspired the development of a matching orange intumescent acrylic sealant, designed to stand out on site and eliminate confusion with traditional white mastics. 

 

Trusted by Professionals, Backed by Support

 

The decision to adopt FAS sealants at scale was driven by their unique combination of testing credibility, installer-friendly application, and clear visual identification. Equally important was the support framework provided, including on-site toolbox talks, installation guides, and video tutorials, ensuring confident and consistent use across developments. 

A senior site compliance manager said: 

“Restricting the use of varied products and moving to standardised solutions delivers real benefits. The selected sealants stood out for their ease of application, test data, and manufacturer support – a winning combination for modern housing.” 

 

A Step Forward for Fire Safety in Housing 

 

This latest adoption reflects a wider shift in the construction industry toward higher safety standards and tested, fit-for-purpose materials. By working hand-in-hand with installers and supply partners, FAS continues to set new expectations for quality and reliability in fire door installations.
