Suitable for use in new-build and renovation projects in roofs and walls.


Thermal, vapour and air tightness barrier foil insulation for use on walls, ceilings and floors.

Features and benefits:

  • Acts as both a radiant barrier and vapour control layer.
  • Vapour and waterproof - resists the passage of warm moist air through walls, floors and ceilings, thus protecting the structure of the building and reducing the risk of condensation.
  • Can be used to enhance thermal performance.
  • Provides a radiant barrier - reflects excessive heat gain during the summer months, and insulates throughout cooler months.
  • Prevents mould and damp.
  • Will contribute to the airtightness of a building.
  • Reduces both convective and radiant heat loss.
  • R-value of up to 2.8 m²K/W.
  • Quick and easy to install.
  • Available in multiple roll sizes to suit project requirements.
  • Manufactured with 40% recycled materials and is recyclable at the end of its useful life.
  • CE marked, and manufactured in accordance with BS EN 13859.
