EPS-Premium External Wall Insulation Systems

PermaRock EPS-Premium external wall insulation systems are high-performance, cost effective, light-weight systems based on low lambda expanded polystyrene (EPS) insulating panels that incorporate microscopic particles of graphite for enhanced thermal performance and to dissipate heat.

The systems are suited for the upgrade of existing buildings and for new buildings, particularly where exemplar levels of thermal performance are required.

Key Features

  • BIM Level 2 compliant (NBS BIM Library)
  • Graphite additive gives the insulation improved thermal performance over standard (white) EPS
  • Low U-values possible – insulation thicknesses up to 300 mm
  • Can assist in achieving Code for Sustainable Homes Levels 4 - 6 and Passivhaus Standards
  • Suited for situations where low imposed loads are critical
  • Class O fire rating* (flame retardent insulation)

*Non-combustible fire breaks should be introduced at each floor level above second floor level up to a maximum building height limit of 18 metres.

Environmental & Quality Standards

  • The system is manufactured and supplied in accordance with BS EN ISO 9001 (Quality Management)
  • The system is manufactured and supplied in accordance with BS EN ISO 14001 (Environmental Management)
  • EPS-Premium insulation is manufactured to EN 13163 and is CFC and HCFC free
  • The insulation has zero Ozone Depletion Potential (zero- ODP) and low global warming potential (GWP) of less than 5
  • Recycling facility for uncontaminated insulation boards is available for site waste
  • Low U-Values are achievable in order to meet or exceed Code for Sustainable Homes, BREEAM and Passivhaus Standards, etc
  • Green Guide to Specification A+ Rating achievable
  • Extremely airtight façades can be achieved
