Polystyrene Block Construction
StoArmat Miral Plaster System - BRANZ Appraisal Certificate 515 (2007)
Combined values of different construction methods
Polystyrene block (EPS block) construction is a snap together hollow block, constructed for a reinforced concrete mass masonry core that is pored into the supported EPS block walls. An established method in the New Zealand construction industry, combining the values and properties of diverse materials.
EPS blocks are light, quick and easy in their installation, giving the designer the ability to form straight and curved walls with exceptional insulation and acoustic properties. Having years of experience in facade insulation, supported by a complex range of modern analytical equipment Sto pursues innovative technology that will meet ecologically acceptable standards. Using this approach Sto has developed a comprehensive range of facade plasters, finishing renders and cladding solutions to enable the specifiers to select an individual style to meet the project requirements.
