STONE wool insulation manufacturer ROCKWOOL has announced the creation of a new cavity barrier called SCB.
The product is an expansion of the firm’s range of cavity fire stopping products and is tested to meet the requirements of BS EN 1366-4:2021.
ROCKWOOL SCB combines the functions of the currently available TCB and PWCB, building and expanding on their scope of application to replace these products. SCB will be available in two widths: 110mm as standard, and 200mm for use where a party wall meets the external cavity.
The product is said to be suitable for use in masonry, timber frame and steel frame cavities up to 290mm, and can be installed horizontally or vertically.
“Responding to customers’ requests, our new SCB has been tested with a steel frame substrate in addition to timber,” said Will Wigfield, product manager HVAC & fire protection at ROCKWOOL. “With a fire rating of up to E120, I45, subject to the application, we are confident that SCB will support specifiers seeking to meet and exceed performance guidelines – for example, the E30, I15, Approved Document B (ADB Volume 1) criteria relating to dwellings.”
TCB and PWCB will be phased out following the launch of SCB and ROCKWOOL recommends switching to SCB specification in advance where possible. Specifications written prior to the expiration of the TCB and PWCB certifications will remain valid and the products remain available until November 15 this year.
