Novia Vapour Control Layer overview sheet

Vapour Control Layers (VCLs) are used to manage the transition of naturally occurring moisture vapour, which is produced by general building use. VCL membranes are formulated with a wide variety of construction designs in mind, delivering the most suitable product for specific solutions for various applications and requirements. A wrongly specified VCL that does not fully consider the intended building use may produce unwanted results. Choosing the correct vapour control membrane for your application is key to any insulated building construction, be it timber frame, steel frame or any other style. The passage of moisture through a building envelope needs to be managed in order to limit unwanted and damaging precipitation or condensation within the interstitial layer.
