Foil Membranes – Sarking – Vapour Permeable

Vapour permeable foil membranes are designed to allow moisture vapour to escape from the building envelope while providing protection against wind, dust, and water ingress. These membranes are essential in wall and roof systems where breathability is required to prevent condensation build-up and maintain healthy indoor environments. The following range of high-performance products is suitable for residential and commercial applications across various climates.

Key Benefits:

• Allow moisture vapour to pass through, preventing internal condensation
• Provide a weatherproof barrier against wind-driven rain and dust
• Enhance thermal performance when used with air cavities
• Improve indoor air quality and building durability
• Suitable for walls and roofs in both residential and commercial buildings
• Compliant with Australian Standards and NCC requirements

Product Range:

• Ametalin Brane – Very High Permeance (VHP)
  • Extremely high vapour permeability
  • Ideal for cooler climates or buildings with low internal air exchange
  • Suitable for roof and wall applications requiring maximum breathability
  • Water-resistant and UV-stabilised for short-term exposure
• Ametalin VapourTech – Roof Wall Commercial (RWC) Medium Duty
  • Medium duty membrane with controlled vapour permeability
  • Balances breathability with water resistance for commercial use
  • Recommended for both roof sarking and external wall wraps
  • Reinforced for added strength and durability
• Proctor – Commercial Wrap (CW)
  • Highly breathable commercial-grade wall wrap
  • Designed to minimise condensation risk in ventilated cavities
  • Compatible with a wide range of cladding systems
  • UV and weather resistant for external wall applications
• Proctor – High Tensile Sarking (HTS)
  • Vapour permeable with enhanced mechanical strength
  • Suitable for pitched roofs and wall systems in demanding conditions
  • High tear resistance for long-lasting performance
  • Engineered for use in high wind and bushfire-prone areas

These vapour permeable sarking membranes provide advanced moisture management and protective benefits, making them essential for compliant, energy-efficient, and healthy buildings.
