NCC Roof Ventilation Follow-Up: BAL Zones, Vermin Gaps & Anticon vs Ventilation

This video is a follow-up to our popular breakdown of Roof Changes to the Australian National Construction Code (2025). In this update, we address crucial aspects that weren’t fully covered in the original video — including vermin control strategies, BAL (Bushfire Attack Level) requirements for fire-prone areas, and the pros and cons of using traditional Anticon insulation versus ventilated roof solutions. We dive into how ventilation systems can be a valid alternative to Anticon when it comes to acoustic performance and condensation management — and what builders, architects, and certifiers should watch out for when it comes to compliance and long-term durability. ⚠️ Whether you’re specifying roofs for BAL-rated zones or dealing with condensation issues in cool or humid climates, this is essential viewing. ✅ Topics Covered: Vermin proofing vented roof systems BAL zone requirements & NCC compliance Anticon vs roof ventilation for acoustic & moisture control Managing condensation risks and roof longevity 👉 Watch the original video here:    • Roof Changes to the Australian National Co...   🔔 Don’t forget to like, subscribe and share if you find this useful! 00:00 Intro 00:33 BAL 02:38 Vapour Permeable Air Tight Foil Wrap 03:44 Vermin Solutions For roofs 05:10 Anticon 11:28 Sound Transmission 13:21 Low Pitched Roofs
