Cavity System 2

Cavity systems are extensively used on lightweight framed structures to create a void between the cladding and the sheathed framed structure. Our CS systems 1 & 2 are the next generation of this solution.

These market-leading Cavity Systems consist of Euroclass BS EN 13501 – A1 components, which are mechanically fixed back to the inner sheathing board to create the designed cavity width with either the insulation board fitted directly to the A1 fillets (CS1 system), or a secondary A1 sheathing board and insulation (CS2 system). Our A1 EWI recladding systems are supplied with a mineral top coat finish.

A proprietary base coat render is applied with a reinforcing plastic coated glass fibre mesh prior to the application of the required finishes.
