Description

The Enviro Cladding System is a non-load-bearing external wall cladding fixed to battens on an external load-bearing wall.

The Enviro Cladding System consists of 50 mm-thick steel-reinforced Autoclaved Aerated Concrete (AAC) panels, 2200mm wide x 600mm high, mounted horizontally on H3.2 treated timber or high density expanded polystyrene (EPS) cavity battens and screw fixed to the external loadbearing wall. The Enviro Cladding System includes a plastered rendered coating to the exterior face of the panel.
