Powerlon AVCLs act as barriers to prevent moisture within the building’s warm air from reaching the insulation layer and forming interstitial condensation.

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

Powerlon Ultrablock barriers are thermo-reflective reinforced vapour control layers incorporating encapsulated aluminium foil or metallised barriers layers to maximise energy efficiency.

Powerlon VCLs and UltraBlock membranes have CE Marking for "Flexible sheets for waterproofing – Plastic and rubber vapour control layers."

Industrial Textiles & Plastics Ltd is ISOQAR Quality Assured and certified to ISO 9001.

Application

Suitable for roof, wall and floor installations, Powerlon VCLs can be used on warm and cold, supported and unsupported, ventilated and unventilated roofs. It is suitable for all roof types and walls in timber frame constructions. For high humidity builds, Powerlon UltraBlock is recommended.

Installation

Powerlon VCLs are installed on the warm side of the insulation. Vapour control layers are impermeable: they prevent moisture and warm air from reaching the insulate. Installed on the warm side of the insulate VCLs protect insulates from interstitial condensation. As impermeable air barriers, VCLs also increase the building's air tightness. The reflective foil surface improves the insulation characteristics by reflecting heat back into the build.

Full illustrated installation instructions are supplied with each roll

Powerlon Tapes, including Penetration Tape, FR Aluminium Tape and Double-sided Jointing Tape, complement the Powerlon UltraPerm range for professional installation. See Powerlon Accessories.

Certification

CE Marking is required for many products. It

  • shows that the manufacturer has checked that these products meet EU safety, health or environmental requirements
  • is an indicator of a product’s compliance with EU legislation
  • allows the free movement of products within the European market
