The National Construction Code 2022 Vol 1: F8D5 / ABCB Housing Provisions Standard 10.8.3 for a Traditional Pitched Roof ≥15°-75° requirement mandates “7,000mm²/lm at the eaves and 5,000mm² at high level.

Achieving this standard is straightforward and easy.

Our G1200N Over Fascia Vent 10mm guarantees a calculated airflow of 11,000mm²/lm, ensuring compliance effortlessly.

For High-level ventilation, the G630 Lap Vent is a quick and easy install that allows high-level ventilation in line with NCC requirements, that requires no change of application to wet fix ridge capping.

  • 3,000mm²/unit
  • Allows warm moist air to escape the roof cavity
  • Perfect for new builds or retrofit
  • Is highly recommended to only apply high-level vents with some form of Over Fascia or Eaves ventilation
  • Requires no change in ridge capping applications
  • No tools or fixing accessories required
  • Must be applied to horizontally laid membranes
