Petrapanel® AAC Cladding System

The Petrapanel® Cladding System is a cavity-based external wall cladding system for residential and light commercial type buildings where domestic construction techniques are used.

The system consists of autoclaved aerated concrete (AAC) panels (Petrapanels) fixed over polystyrene battens to form a nominal 20 mm cavity. The coating system consists of a minimum 5 mm thickness of fibreglass mesh reinforced renders and cementitious mineral finishing renders applied to the AAC panels. The render system is finished with an exterior paint system. The plaster finish can be applied to give different texture appearances.

Always refer to the Appraisal in full and the technical literature.
