Tags:

The PermaRock EPS external wall insulation (EWI) system is a light-weight, low-cost system based on expanded polystyrene (EPS) insulating panels. The low density of the system makes it especially suitable for situations where low imposed loads are critical and is especially suited for low-rise applications.

EPS insulation can also easily cut on-site to enable features such as ashlar groves and horizontal bands to be created.

Features:

  • Light-weight – suited for situations where low imposed loads are critical
  • Low U-values possible – insulant thicknesses up to 350 mm
  • Class O fire rating
  • Suitable for use below dpc and below ground level
  • UKAS Accredited (BRE Cert No. 158/12)
