Roof & Wall Sarking

Roof & Wall Sarking

Roof & Wall Sarking is a pliable building membrane installed beneath external cladding or roofing materials to improve thermal performance, manage moisture, and protect against weather infiltration. Available in both vapour permeable and non-vapour permeable options, sarking is a vital component in modern construction, enhancing energy efficiency, durability, and comfort in residential and commercial buildings.

Key Benefits:

  • Acts as a secondary weather barrier, protecting against wind, rain, and dust
  • Improves thermal performance when used with reflective air cavities
  • Contributes to building compliance with the NCC and Australian Standards
  • Enhances structural durability by managing internal moisture and condensation risks
  • Suitable for pitched metal or tiled roofs and external wall systems

Types of Sarking:

  • Non-Vapour Permeable Sarking:
    • Blocks both moisture and vapour
    • Ideal for use in metal roofing and general weatherproofing
    • Includes heavy-duty options for bushfire compliance (BAL zones)
    • Common products: Ametalin Trade Select HD/XHD, Firesark
  • Vapour Permeable Sarking:
    • Allows internal vapour to escape while keeping external moisture out
    • Reduces risk of condensation in roof and wall cavities
    • Ideal for climate-sensitive or tightly sealed buildings
    • Common products: Ametalin Brane VHP, Proctor CW, Ametalin VapourTech RWC

Roof & Wall Sarking is essential for creating a well-insulated, weather-resistant, and breathable building envelope—tailored to meet the demands of various climate zones and construction types.
