Novia 500G Vapour Control Layer 2.7m x 50m Roll

Novia 500g Vapour Control Layer is a traditional specification, single-ply, non-laminated, virgin grade blown polythene material for use as an air leakage barrier and vapour control layer (AVCL) in insulated wall, roof and floor applications. It is is particularly suitable for use in residential timber frame applications as it is 2.7m wide. Novia 500g must be installed in conjunction with Novia two-tape sealing system to provide a fully airtight seal.

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.
