Novia Breather Membrane Lap Tape

Product Overview

Novia® Breather Membrane Lap Tape (BMLT) is a sealing and bonding tape which has a high strength acrylic dispersion adhesive and has a non-woven polypropylene carrier. Novia® BMLT is suitable for use in temperatures as low as -10OC with care. This tape is suitable for overlaps and joints on Breather Membranes within both roof and wall applications to seal all membrane overlaps to protect against external environmental conditions and improve airtightness. 

Novia® BMLT can be used with Novia Breather Membranes as an edge and lap sealing tape. To fully complete a breather membrane seal and further reduce the air-leakage of the construction, this tape should be used in conjunction with Novia Double-Sided Adhesive Lap Tape.

Novia Breather Membrane Lap Tape may need to be used in conjunction with breather membranes for use on roofs to meet BS 5534 wind uplift requirements. Please see individual Breather Membrane technical datasheets for guidance and geographical data.

Two sizes are available from stock: Roll size 50mm x 25m and 75mm x 25m. We recommend using the 75mm width, as a wider tape makes it easier to install the membrane on site and a larger surface area provides a better seal.

Novia® BMLT can be found on NBS Chorus and NBS Source software packages. They are available for specifying as additional products, and fall within a variety of relevant clauses.

Full installation and technical details can be found on the datasheets available for download below.
