Cavity System 1

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

Our 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.

Used to allow insulated structures to easily release excess moisture vapour into the atmosphere and keep the internal elements of wall structures dry.
Beads for a rendered façade will ensure the best finished look, ensure durability and help protect the render from water damage and cracking.
The Benx range of silicone, acrylic and mineral renders are a great way to achieve a perfect and long lasting finish.
