StoPoren Panel Facade System

StoPoren Panel Facade Systems creates durable, solid substrates that are incombustible, sound-absorbing and thermally stable, finished with a Sto Render System and complemented with a range of textures.

StoPoren aerated concrete (AAC) panels, reinforced with ductile steel are 2200 x 600 x 50 mm in dimension, fixed and laid horizontally, incorporating a 20 or 40mm ventilated and drainage cavity, building a solid permanent structure. Measured, cut and laid, these solid panels stack up quickly, to close in the exterior effortlessly. This easy-to-use building material can cut residential and commercial build costs and lower construction time considerably. 

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.
