Application

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 with DSLT.


Novia BMLT is required for use with some breather membranes in accordance with BS 5534 wind uplift requirements. The installation of a two-tape system using both BMLT and DSLT will provide a high specification finish.

Description

A sealing and bonding tape which has a high strength acrylic dispersion adhesive, and has a non-woven polypropylene carrier.


Features and benefits:

  • Suitable for installation temperatures starting from -10°C. For best results, a temperature of +5°C is recommended.
  • Suitable for overlaps and joints, on breather membranes within both roof and wall applications.
  • Seals membrane overlaps, and will protect against external environmental conditions and improve airtightness.
  • Should be used in conjunction with Novia Double Sided Lap Tape (DSLT).
