FIREFLY VapourSafe Non-Combustible Sarking is an extra heavy duty pliable, vapour permeable, membrane vapour barrier consisting of a layer of woven glass fabric with a hydrophobic surface.
FIREFLY VapourSafe represents a cutting-edge vapour permeable membrane for walls and roofs, fabricated to serve as a pliable, non-combustible barrier in Type A and B fire-resistant constructions, as well as across various construction types where superior passive fire safety, water ingress prevention and vapour permeability is desired. Its advanced hydrophobic treatment blocks liquid water whilst allowing water vapour diffusion within the wall structure.
Constructed with non-combustible Fortaglas weave, it boasts an Extra Heavy Duty strength classification, ensuring resilience against punctures and maintaining ember protection for all BAL zones.
Available in 1250 mm x 50 m, thickness 0.2 mm, 62.5m² per roll, 14.5kg weight per roll.

Understanding the climate zone where you’re building is essential to selecting the right sarking/building membrane. To help you navigate these requirements, we’ve added the Australian Building Codes Board’s interactive Climate Zone Map below. This tool provides valuable climate-related information aligned with the National Construction Code (NCC), making it easier for builders, designers, certifiers, regulators, and industry professionals to see how climate conditions affect building standards.The map features a combination of dynamic layers and static references, including NCC climate zones, relative humidity patterns, and alpine regions—offering comprehensive insights to guide your material choices and ensure compliance.
