StoArmour Panel Facade System
Description
The StoArmour Panel Facade 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 50 or 75 mm thick autoclaved aerated concrete (AAC) panels (StoArmour panels) fixed over high density polystyrene battens to form a 20 or 40 mm cavity, or timber cavity spacers to form a 40 mm cavity. The coating system consists of a nominal 5 mm thick cement-based render applied to the StoArmour panels, an approximate 2.5 mm thick coat of fibreglass mesh reinforced synthetic resin render (StoArmat Render System only), and an approximate 1-3 mm thick coat of coloured finishing render. The render system is 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 facade from the external wall framing with a nominal 20 or 40 mm drained cavity.
