StoPoren Panel (AAC) Cladding Construction
Description

StoPoren Panel creates durable, solid substrates that are incombustible, sound absorbing and thermally stable. StoPoren Panels are 2200 x 600 x 50mm in dimension and are laid horizontally to build a solid permanent structure. The materials are easily cut allowing the designer freedom to create clean straight lines.

The autoclaved aerated concrete (AAC) panels (StoPoren panels) are fixed over high density polystyrene battens to form a 20 or 40 mm drainage cavity, or timber cavity spacers to form a 40 mm drainage cavity, allowing for a dry zone between the interior and exterior claddings and are coated in a Sto Plaster System of your choice.

Installations are carried out by a Sto Registered Licensed Building Practitioner with the added protection of a 15 or 20 year Sto System Warranty and 5 year renewable Workmanship Warranty plus Maintenance Schedule.
