Product Description

Powerlon VCLs are polyethylene-based vapour control membranes reinforced with a scrim to provide sufficient tensile strength in wall and roof installations.

Air Barriers ensure that the building envelope is properly sealed to control ventilation and prevent heat loss in compliance with Building Regulations Part L. Installed on the warm side of insulation, Vapour Control Layers (VCLs) protect insulates from interstitial condensation. As impermeable air-barriers, VCLs also increase the building’s air-tightness.

UltraBlock is a range of thermo-reflective reinforced Vapour Barriers incorporating encapsulated aluminium foil or metallised barrier layers to maximise energy efficiency. The reflective foil surface improves the insulation characteristics of the installation reflecting heat back in to the building. FR suffixes indicate Flame Retardant grades.

The membranes’ lightness, high performance and ease of installation provide cost-effective vapour control systems for the building envelope.

Grade: 210gsm.


  • Suitable for roof, wall and floor installations.
  • Reinforced polyethylene with high tensile scrim reinforcement.
  • Controls vapour to minimise interstitial condensation.
  • Air barrier for controlling ventilation.
  • Choice of grades.
