Description

CONSTRUCTION


FIREFLY MEMBRANE WP is a strong, breathable woven glass substrate aluminised on one side, suitable for jointing with foil tape.


KEY BENEFITS

  • Weatherproof and breathable, FIREFLY Membrane WP is designed to be a vapour permeable, reflective insulation layer in commercial facades and rain screen cladding systems
  • Classified A2 (EN13501-1), suitable for use over 18m – combining non-combustible fire resistance with traditional construction membrane performance requirements
  • Ideal for upgrading fire performance both on remedial work and new installations of cladding and rain screen systems
  • Outstanding strength and durability both before and after age testing, demonstrating sustainable performance attributes when weathered
  • Lightweight, flexible, simple to install and resistant to damage during installation at temperatures as low as -40°C
  • Jointed by foil tape
