Track-EPS External Wall Insulation Systems

The PermaRock Track-EPS system is a mechanically fixed external wall insulation (EWI) system which can be installed to create a drained cavity space behind the insulation panels to meet the specific requirements of NHBC, Zurich and other building insurers for external wall insulation application to timber and metal frame constructions in new buildings.

The use of tracks to support the insulation enables greater flexibility in overcoming deficiencies in irregular or uneven backgrounds, to achieve very flat surfaces upon completion.

Key Features

  • For buildings up to 18 m in height.
