A2 Steel Frame Stone Wool Acrylic Brick Slip System

The Wetherby Direct Fix Steel Frame System has been developed to allow installation of A-rated Wetherby systems to a sheathed steel frame substrate. The direct fix application allows the system to be directly mechanically fixed with adhesive (where required) removing the need for a cavity and the cavity fire-stopping behind the A1 Stone Wool insulation. Suitable for use on a variety of project types such as schools, student accommodation and high-rise reclad projects, the system has proven incredibly popular since its launch in 2022.

Our Stone Wool Acrylic Brick Slip system emulates traditional brickwork with its lightweight, durable design. Crafted from quartz sand and acrylic resin, these slips offer flexibility and achieve an A2-s1,d0 fire rating to BS EN 13501-1 when paired with a Wetherby Stone Wool insulation system.
