AAC Panel Construction
Render Systems for AAC Panel Construction
Overview
The Sto Render System has been developed for maximum system longevity, reliability and weather resistance. The StoArmat Render System is fracture, impact resistant and engineered to provide optimal protection and finish for AAC Panel construction, to compliment, protect and enhance this building element.
Developed in Europe, lightweight, steel-reinforced autoclaved aerated concrete (AAC), approximately 20% the weight of traditional concrete, became commercially available in the 1930s. This innovative building material has gained popularity as a solid, durable, energy-efficient product providing insulation, fire and sound resistant properties.
Sto has developed a comprehensive range of facade renders and solutions to enable specifiers to select an individual style to meet the project requirements, providing optimal protection and finish with warranty for all AAC Panel construction.

StoArmat Render System over AAC Panel
A BRANZ Appraised high-performance render system providing exceptional crack resistance and weather protection. Application includes a stay-dry sealer for AAC Panel, mineral-basecoat render to straighten any irregularities, with uPVC flashings to lock into junctions and joinery forming a neat weathertight seal. Application is followed by StoArmat reinforcement render with glass fibre mesh, providing engineered reinforcement to reliably dissipate tensile, seismic and shear stress. Finished in a choice of different Stolit coloured finishing renders and StoColor.
Installations are carried out by a Sto Registered Licensed Building Practitioner with the added protection of a StoArmat 15 or 20 Year Warranty with StoService Assurance, guaranteeing building code compliant materials are used and application meets building code standards, including a service plan for long-term security.
