Introducing FIREFLY VapourFlex

18 June 2024

Non Combustible, Vapour Permeable Sarking

FIREFLY VapourFlex is a cutting-edge, extra heavy duty, 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 and vapour permeability is desired.

Its enhanced hydrophobic treatment blocks liquid water whilst allowing water vapour diffusion within the wall structure.

Constructed with non-combustible Fortaglas weave, it boasts “extra heavy duty” strength classification ensuring resilience against punctures and maintaining ember protection for all bushfire (BAL) zones.
