USE AREAS
FIREFLY® VapourSafe® Membrane is specifically designed with modular and offsite construction in mind. Its lightweight, durable composition makes it easy to handle in factory conditions, while its Class A2-s1, d0 fire classification ensures compliance is built in to every panel before arriving onsite. Typical applications include:
- Modular and offsite construction – pre-fabricated wall and façade panels where consistent fire safety and weather proofing must be assured during manufacture, transport, and installation.
- Rainscreen and ventilated façade systems – providing a vapour-permeable, weather resistant layer behind cladding systems.
- High-rise and high-risk buildings, residential, commercial, healthcare and education projects where non-combustible materials are essential above 18m.
- Refurbishment and remedial works – upgrading the fire performance of existing façades without compromising breathability.
CONSTRUCTION
VapourSafe® Membrane is a strong, breathable coated woven glass substrate, suitable for jointing with foil tape.
KEY BENEFITS
- Weatherproof and breathable, FIREFLY® VapourSafe® Membrane 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
- Excellent strength and durability both before and after age testing, demonstrating sustainable performance attributes when weathered.
- Lightweight, flexible, resistant to damage during installation at temperatures as low as -40°C
- Jointed by FIREFLY® membrane / foil tape
