BRE Global Certificate 158/12 - PermaRock External Wall Insulation and Render Systems

PermaRock’s BRE-Global Certification Certificate (No. 158/12) expands on our existing scope of external wall insulation and render systems accredited. PermaRock External Wall Insulation and Render Systems (PEWIRS) consist of (mono- or dual-density) mineral fibre, phenolic foam, expanded polystyrene (EPS), or polyisocyanurate (PIR) foam insulation finished externally with polymer modified renders, polymeric coatings with aggregate finishes, brick slips or polymer bound brick effect slips to simulate brickwork. PermaRock Systems are for application to external vertical walls of new or existing buildings of masonry, dense and no-fines concrete, timber or light gauge steel frame construction. Carrier rails can be used in conjunction with EPS to provide a 20mm drained cavity where required.
