|PermaRock External Wall Insulation and Render Systems||
PLEASE SEE IMPORTANT NOTICE REGARDING NEW REGULATIONS RELATED TO FIRE PERFORMANCE AND CLADDING SYSTEMS ON EXTERNAL WALLS OF BUILDINGS WITH A STOREY 18M ABOVE GROUND LEVEL IN ENGLAND IN THE RED BOOK INTRODUCTION BELOW
PermaRock External Wall Insulation and Render Systems (PEWIRS) consist of mineral rock fibre, phenolic foam or expanded polystyrene insulation finished externally with polymer modified renders, polymeric coatings with aggregate finishes or brick slips to simulate brickwork.
The PermaRock Systems are for application to external vertical walls of new or existing buildings of masonry, dense or no-fines concrete, timber or light gauge steel frame construction. Carrier rails can be used in conjunction with expanded polystyrene to provide a drained cavity where required on steel framed or timber framed constructions.
The components of the external wall insulation and renders systems are as follows:
- Carrier rails
- Insulation (mineral fibre, expanded polystyrene and phenolic foam)
- Fixings for insulation
- Base coat materials
- Reinforcing mesh
- External finishes
