11. Stone Wool Brick Slip System for a Steel Frame Substrate

Steel Frame Stone Wool 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 it’s launch in 2022.

This system offers a cost-effective alternative to traditional brick façades, with an A1 fire rating to BS EN 13501-1 when paired with Wetherby Stone Wool insulation, it ensures energy efficiency, non-combustibility, and superior soundproofing.

*Some new build insurers such as NHBC, Premier Guarantee and LABC insist on a drainage cavity on new build housing projects. Therefore a Wetherby cavity rail system would be the best solution.  Please see the links below to view suitable Wetherby cavity rail systems.

Product Information

At the core of our Stone Wool Silicone Render system lies Rockwool insulation, providing outstanding thermal performance, unparalleled breathability and superior acoustic properties in comparison with other insulants on the market. Stone Wool is classified as A1 non-combustible as an individual product.

  • Outstanding thermal and acoustic properties
  • Non combustible
  • Easily cut and shaped
  • Can be installed to flat & curved surfaces
  • Open cell structure allows the façade to breath

Wetherby Brick Slip Systems stand out as a game-changer, particularly in scenarios where real brick usage is unfeasible or impractical. The brick slips are manufactured in the same way as real brick providing an identical finish, attaining A1 properties. Brick slip ‘pistol’ corners are manufactured as corners, with no visible joints, ensuring a real brick appearance across a façade.

  • Professional-grade, authentic brick finish
  • Enhanced precision and alignment
  • Exceptional impact resistance & adhesion properties
  • A1 fire rated
