PermaRock EPS-Premium external wall insulation systems are high-performance, light-weight systems based on low lambda expanded polystyrene (EPS) insulating panels that incorporate microscopic particles of graphite (Grey EPS) 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

  • BRE Global Certification
  • BIM Level 2 compliant
  • 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 BREEAM and Passivhaus Standards
  • Suited for situations where low imposed loads are critical
  • Class O fire rating* (flame retardant 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.

Decorative Options

PermaRock’s wide selection of renders and finishes provide almost limitless options for texture, colour and shape. In addition to flexible, through-colour acrylic, silicone and SiliconeUltra Finishes, the PermaRock EPS-Premium external wall insulation system can be finished with PermaRend Mineral K/R Finishes, PermaRock Brick-effect Render or Brick Slips, with tough, durable PermaRock Stone Chip Render or with PermaRock Dry Dash.

With our through-colour renders you can choose from over 1300 colour shades and if you can’t find your exact colour requirements from our extensive colour palettes, PermaRock is able to colour match to RAL, BS4800 and other widely used commercial colour ranges with many of our decorative finishes.

Environmental & Quality Standards

The system is manufactured and supplied in accordance with the BS EN ISO 9001 (Quality Management) and BS EN ISO 14001 (Environmental Management) standards.
