Novia 500 Gauge Vapour Control Layer
Application

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

Description

A traditional specification, single-ply, non-laminated, virgin-grade blown polythene material. Its 2.7 m width makes it particularly suitable for use in residential timber frame applications. To provide an airtight seal, it must be installed in conjunction with the Novia two-tape sealing system.


Features and Benefits:

  • Air-leak barrier and vapour control layer (AVCL).
  • Supplied centre-folded in 2.7 m width, ideal for timber frames.
  • Virgin-grade, high-quality material.
  • CE approved and CPR compliant.
  • Complies with BS EN 13984.
  • Easy to install, can see battens (translucent green tint).
  • Minimizes interstitial condensation.
  • Improves the insulation performance.
  • Low cost solution.
  • Helps buildings meet 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 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.
