This kit has been put together by Novia to offer all materials and fittings needed to secure a long-lasting and high-performance vapour control layer. Novia 500 VCL can be used as a vapour control layer for timber framed walls and it acts as an air barrier too. The tapes provided in this kit, Novia double-sided butyl tape and Novia foil tape, will give a tight seal and make Novia 500 VCL perform for longer. Manufactured from 125-micron thick blown polyethylene, Novia 500 VCL is lightweight and it can be used alongside other Novia breather membranes for an air-tight and vapour resistant system.
