Novia STRP Pro is our premium specification reinforced and foil laminated polythene vapour control membrane. It is designed for use in insulated wall, roof and floor applications, including warm flat roofs, where very high concentrations of moisture vapour need to be controlled. Novia STRP Pro is particularly suitable for use in metal profile clad industrial buildings, the education sector and commercial properties, but can be used in all insulated building constructions. This membrane must be professionally installed in conjunction with our 2-tape sealing system to ensure a fully airtight seal. PropertiesLength:50m. Width:1.6m. Roll size: 80m2. Weight:27kg. Nominal weight:314gsm. Reflectivity:57%. 2-tape sealing system:to be used with 30mm butyl tape & 60mm metallised BOPP tape. InstallationVCLs 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.
