StoStucco Render Cavity System

The StoStucco Render Cavity System is a cavity-based monolithic render wall cladding. It is designed to be used as an external wall cladding system for residential and light commercial type buildings where domestic construction techniques are used.

The system consists of a stainless steel lath fixed over timber battens to form the cavity. The coating system consists of an approximate 18 mm thick polystyrene bead saturated, polymer-modified, cement-based render applied to the lath, an approximate 2.5 mm thick coat of mesh reinforced synthetic resin render, and an approximate 1-3 mm thick coat of coloured finishing render. The render is then finished with a Sto coating.

The system incorporates a primary and secondary means of weather resistance (first and second line of defence) against water penetration by separating the cladding from the external wall framing with a nominal 25 mm wide cavity.
