This AirGuard Vapour Control Layer bu DuPont is designed to control the transfer of moisture between the exterior and interior of a wall structure in building construction. Intended for installation on the “interior” side of the building structure with the logo side facing into the interior of the room. Use to create an airtight seal across wall studs after adding insulation, before applying plasterboard or drylining products. 

  • Supplied in rolls
  • BBA certified for warm and cold roof applications
  • Use in combination with a Breather Membrane
  • Seal with Butyl tape to create an airtight seal

What is a VCL?

 Vapour Control Layers (VCLs) are designed to manage the passage of moisture through a building's exterior walls, foundations and roofs and limit condensation within the interstitial layer between roofs, walls and floors. Particularly in high-humidity areas like the UK, water-laden air can condense on these structures causing damage over the long term, and reducing the thermal performance of insulation. 

It is advised to seal your Vapour Control Layer with double-sided butyl tape, followed by a BOPP tape to improve airtightness and increase the efficacy of the Vapour Control Layer. 

How do I Apply a Vapour Control Layer?

A vapour control layer should be applied on the interior side of any wall, roof or flooring, over timber studs before the internal lining. It should be 100% sealed to the structure with double-sided butyl tapes, pre-applied to all areas where a fixing is to be made, and finished with metallised BOPP tapes to ensure a complete vapour seal.

It is best used in conjunction with a Breather Membrane applied to the exterior side of the structure.
