ROCKWOOL® has launched a new cavity barrier product, SCB (Sleeved Cavity Barrier) that is tested in accordance with BS EN 1366-4:2021. SCB replaces TCB and PWCB, giving specifiers an option to swap their specification on new and existing projects subject to advice from the ROCKWOOL Technical Team. TCB and PWCB are discontinued as of 15th November 2024.
ROCKWOOL SCB combines the functions of TCB and PWCB, building and expanding on their scope of application. SCB is available in two widths; 110mm as standard, and 200mm for use where a party wall meets the external cavity. It is suitable for use in masonry, timber frame and steel frame cavities up to 290mm, and can be installed horizontally or vertically.
ROCKWOOL SCB also features:
- Suitable for cavities up to 290mm
- Horizontal and vertical installations
- Fire rating up to E120, I45, subject to the application
"Responding to customers’ requests, SCB has been tested with a steel frame substrate in addition to timber,” said Will Wigfield, HVAC & Fire Protection Product Manager 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.”
SCB is also tested for masonry/concrete to concrete, OSB (timber frame) and CP board (steel frame) applications, with a consistent 10mm compression fit.
ROCKWOOL® SCB replaces TCB & PWCB which are discontinued as of 15th November 2024. Please swap your existing specifications of TCB & PWCB to SCB now.
