Скачать или смотреть 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
