Novia VC2 Air Leakage and Vapour Control Layer
Application

For use as an air leakage barrier and vapour control layer (AVCL) in insulated wall, roof and floor applications.

Description

A technologically advanced, flame resistant, reinforced and airtight vapour check membrane. The flame resistant additives mean that the membrane will not readily ignite or continue to burn in small fires, which adds an extra level of safety to building designs. To provide an airtight seal, it must be installed in conjunction with the Novia two-tape sealing system.

Features:

  • Air-leak barrier and vapour control layer (AVCL).
  • CE approved and CPR compliant.
  • Complies with BS EN 13984.
  • Easy to install, can see battens (translucent).
  • Tough, tear-resistant (scrim reinforced).
  • Minimizes interstitial condensation.
  • Improves the insulation performance.
  • High quality, low cost solution.
  • Flame resistant to EN 13501-1, class E.
  • Helps buildings meet the requirements of BS 5250.
  • Install with Novia two tape sealing system.
  • Ideal for use with Novia Breather Membranes in insulated frame applications.

Tape:

  • 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.

Application:

For use as an air leakage barrier and vapour control layer (AVCL) in insulated wall, roof and floor applications.
