A1 Steel Frame Carrier Board Brick Slip System

ROCKWOOL Wall Systems Carrier Boards are designed to provide steel frame structures with a rendered or brick finish, where the framed substrate already meets the required U-values. The A1 ROCKWOOL Wall Systems Carrier Board can be fixed to either metal cavity rails or timber battens, creating a protective cavity behind the non-combustible board.

Carrier board systems provide a high-impact, durable and aesthetically pleasing façade whilst taking up minimal space; using the minimum 15mm Cavity Rail means the full system is less than 50mm in depth.

The Brick Slip Carrier Board system achieves an A1 non-combustible fire rating to BS EN 13501-1, allowing installation on projects of any height. The unique ROCKWOOL Wall Systems RagRail is available in multiple sizes and simplifies installation, ensuring exceptional flexibility in design options.
