Novia VC8 Reflective Air Leakage and Vapour Control Layer 1.5m x 50m Roll

Novia VC8 Reflective Air Leakage and Vapour Control Layer is a technologically advanced, 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 prevents any surface condensation problems that may occur and remains highly reflective and so delivers greatly improved R and U-values. Novia VC8 must be installed in conjunction with Novia two-tape sealing system to provide a fully airtight seal.

CHARACTERISTICS

• High quality low cost solution,
• High reflectivity and low emissivity surface, which can deliver improved U-values,
• Technically advanced ultrasonic bonded laminate,
• Minimises interstitial condensation,
• Improves the insulation performance,
• CE approved to BS EN 13984,
• Meets the requirements of BS 5250: 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.
