Siderise Supports SCi’s research into Cavity Barriers in SFS Masonry Facades

Siderise Insulation were delighted and proud to be involved with the creation of the Steel Construction Institute’s (SCi) Technical Information Sheet on ‘Cavity barriers in light steel frame buildings’, collaborating on a programme of cavity barrier testing in these applications. 

The purpose of SCi Technical Information Sheet P438 is to provide clear and evidenced guidance on the performance of cavity barriers in light steel framed buildings. To meet this aim, we worked closely with SCI Light Steel Forum— in partnership with other passive fire protection manufacturers, industry leaders and the UKAS-accredited test house, WarringtonFire— to undertake multiple tests with Siderise EW Cavity Barriers for Masonry External Walls. These were completed  to EN1366-4:2021 - Fire resistance tests for service installations – Linear Joint Seals, using a masonry outer leaf and an inner leaf  of various light steel frame wall constructions, and with a masonry inner leaf for comparison. The results showed that the equivalent performance of cavity barriers can be obtained for  cavity barriers between masonry cladding and an inner leaf of masonry or an inner leaf of  light steel framing.

Speaking of the collaboration, Chris Hall, External Affairs Director at Siderise Insulation revealed: “At Siderise, we are great advocates for industry collaboration and resource sharing, believing it is vital to creating a better, more accurate and ultimately safer built environment. To be able to support this testing scheme, in partnership with the SCI Light Steel Forum, was very important to us as a business and we hope its results are beneficial to the light steel construction sector, and our industry as whole.”
