A2 Steel Frame Cavity Rail Stone Wool Acrylic Brick Slip System

The Wetherby Stone Wool Acrylic Brick Slip Cavity Rail system is an ideal solution for steel frame substrates requiring a drainage cavity between the sheathed steel frame substrate and insulation.

The cavity is ‘partially ventilated’ meaning the effect on the through wall U-value is minimal, with small drainage holes in the base track allowing any moisture to escape from the system. New build insurers such as the NHBC, Premier Guarantee and LABC insist on a cavity on new build projects, making the Wetherby Cavity Rail system an ideal solution.

The unique Wetherby RagRail helps to simplify the installation of this system and combined with the Stone Wool and Acrylic Brick Slips, achieves an A2-s1,d0 fire rating to BS EN 13501-1, allowing installations to a building of any height. Our Stone Wool Acrylic Brick Slip system is quick to install and emulates traditional brickwork with its lightweight, durable design.
