FireSark® Micro-perforated is a premium, reflective, non-combustible wall wrap engineered for maximum protection and performance in bushfire-prone environments. Ember-proof and suitable for installation across all BAL zones, it functions as both an Air Barrier and a Class 3 Vapour Permeable membrane, combining safety, durability, and efficiency in one solution.

Designed as an Extra Heavy Duty vapour permeable reflective wall wrap, FireSark® Micro-perforated reduces the risk of interstitial condensation within building systems while delivering superior fire resistance that exceeds the requirements of the 2019 National Construction Code for bushfire-prone areas. Its dense pattern of micro-perforations allows controlled water vapour escape from wall structures, making it particularly effective in drained cavity systems within Climate Zones 6–8.

Beyond vapour management, FireSark® Micro-perforated acts as a robust barrier against air leakage, radiant heat transfer, draughts, and dust penetration, contributing to healthier, more resilient building envelopes. Constructed as a flexible three-layer system, it combines non-combustible E-glass fabric, 97% reflective aluminium foil, and a durable fire-resistant polymer adhesive. This advanced composition ensures ultra-strong performance, chemical inertness, and long service life, making FireSark® Micro-perforated a trusted choice for modern construction where fire safety and building integrity are paramount.
