Novia VC200 Reflective Air and Vapour Control Layer


For use in insulated wall, roof and floor applications requiring high moisture resistance. Also suitable for use in conjunction with Novia breather membranes for insulated frame applications.


A highly reflective airtight vapour-control layer (AVCL) that delivers a low vapour permeability solution and helps to prevent interstitial condensation problems.

Features and benefits:

  • High performance air and vapour control layer.
  • High reflectivity/ low emissivity surface.
  • Low moisture permeability.
  • Maximizes the insulation performance.
  • Technically advanced laminate.
  • Delivers improved thermal resistance (R-values) and thermal transmittance (U-values).
  • High quality, low cost solution.
  • Helps buildings to meet the requirements of BS 5250.
  • CE approved to BS EN 13984.

Must be installed with Novia dual tape sealing system to provide a fully airtight seal. Consult manufacturer for information.


  • For professional installation, all Novia® VCL products should be 100% fully sealed to the structure using a Novia® double-sided butyl tape and one of the foil or BOPP lap tapes. The wider the tape used, the stronger the final seal will be and the easier it will be to install.

Novia® recommends the 30 mm wide butyl tape and 60 mm metallized BOPP tape for all standard VCL installations.
