A translucent reinforced polythene membrane VCL for use with metal profile clad industrial buildings or commercial properties. STRP is supplied in single-wound extra-wide 2m widths. Vapour Control Layers (VCLs) are used to manage the transition through the building envelope of naturally occurring moisture vapour, which is produced by general building use. Our range of VCL membranes are formulated with a wide variety of construction designs in mind, delivering specific solutions for various applications and requirements. Novia STRP (Super Tough Reinforced Polythene) VCL is a high specification reinforced polythene laminate material, suitable for use as a vapour control layer within metal profile clad industrial buildings within the education sector, commercial properties and high specification residential timber frame constructions, or where control of the passage of water vapour is required. This product performs the additional task of an air-leakage barrier, to prevent losses due to unwanted convection flows. We advise the use of Novia compatible butyl and foil sealing tapes to ensure complete barrier integrity throughout the entire life of the product. Novia STRP VCL should be used in combination with Novia breather membranes to provide an air-tight and vapour resistant system.  There is a flame resistant coating on one side of this product to grade E: EN 13501-1. This product is CE Approved to EN 13984 and CPR compliant. Propertes Length: 50m. Width: 2m. Roll size: 100m2. Weight: 250gsm. Roll weight: 25kg. Reaction to fire: Class E to EN 13501-1. Certification: CE approved to EN 13984. CPR complaint. Installation guide VCLs should always be installed on the warm side (i.e. 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 (i.e. the outside). Novia membranes will only perform their job if they are correctly installed using Novia tapes as part of a system. Novia uses a two-tape sealing system on all of our VCL products. It is essential that Novia membranes are installed correctly using our tapes, otherwise these products will not provide the necessary building design outcomes. One of the major causes of condensation problems within finished buildings is due to poorly installed membranes and where incorrect tapes have been used. All Novia VCL products should be 100% fully sealed to the structure using one of our double-sided butyl tapes, and one of the foil or BOPP lap tapes to professionally complete the installation. The wider the tape used, then the stronger the final seal will be, and the easier it will be to install as there is more margin for error, so choose a tape based on your own particular application and budget. Novia recommends our 30mm wide butyl tape and our 60mm Metallised BOPP tape for all standard VCL installations.
