Novia VC2 Air Leakage and Vapour Control Layer 1.5m x 50m Roll

Novia VC2 Air Leakage and Vapour Control Layer is a technologically advanced, flame resistant, reinforced and air-tight vapour check membrane for use as an air leakage barrier and vapour control layer (AVCL) in insulated wall, roof and floor applications. This membrane adds an extra level of safety to building designs as it will not readily ignite, nor will it continue to burn in small fires. Novia VC2 must be installed in conjunction with Novia two-tape sealing system to provide a fully airtight seal.

CHARACTERISTICS

• High quality low cost solution,
• Easy to install,
• Translucent,
• Tough and tear-resistant,
• Scrim reinforced,
• Minimises interstitial condensation,
• Improves the insulation performance,
• Flame resistant to EN 13501-1 Class E,
• CE Approved and CPR compliant,
• Complies with BS EN 13984,
• Meets the requirements of BS5250:2011,
• Ideal for use with Novia Breather Membranes in insulated frame applications
  

APPLICATION

• For wall, roof and floor applications as an air leakage barrier and vapour control layer.

INSTALLATION

• VCLs should always be installed on the inside within all wall, roof or floor insulated frame applications, and would normally be used in conjunction with Novia external breather membranes which are situated on the cold side (on the outside).
• Fix the membrane to the structure using suitable galvanised or stainless permanent fixings,
• All VCL membrane joints should have a minimum 150mm overlap and be situated on a stud, rafter or timber,
• To improve overall airtightness, butyl tape is pre-applied to all the areas where a fixing is to be made.
• Ensure that the membrane is not damaged during installation, and that all service entry points are properly sealed.
