Novia Metallised BOPP (Biaxially Oriented Polypropylene) tape is a high tack, tear-resistant, low emissivity, and low moisture vapor permeability sealing tape designed for air and vapor control layers and damp-proof membranes. It is essential for edge and lap sealing when used alongside Novia's double-sided butyl sealing tapes, ensuring optimal airtightness and preventing interstitial condensation. This tape features a high-spec acrylic dispersion adhesive for excellent adhesion and utilizes high-performance metallised polyester, enhancing its overall strength and durability. Additionally, it is a crucial component for installing the Novia Methane Pro membrane, serving as a final barrier against methane emissions from construction.
