Wetherby EWI System Achieves BS8414 Fire Performance Standard

Sheets of expanded polystyrene (with mineral wool fire barriers) were adhesively and mechanically fixed to the masonry test wall and a large fire lit to emulate a potential fire within a property.

The flame and heat generated really put the system to the test, yet it passed with flying colours.

This result will undoubtedly strengthen Specifier confidence in Wetherby’s External Wall Insulation Systems and the company’s dedication towards providing quality systems that are technically robust.

This is the fourth Wetherby system to achieve BS8414 certification.
