Thermabar 824 Reflective Foil Insulation

Heavy Weight double sided 2-way reinforced reflective foil insulation, consisting of two layers of burnished aluminium bonded to quality high strength kraft paper, skrim reinforced.

Key Features

  • Reflective foil insulation
  • Cost effective
  • Non-Fire Retardant

Advantages

Acts as a vapour control layer sarking when installed beneath the primary roofing material, with good tear resistance. Due to its highly reflective properties, when used in conjunction with a still air-space, provides thermal insulation. Can be used as a vapour control layer, improving thermal performance when installed and taped on the warm side of bulk insulation.
