Roof Changes to the Australian National Construction Code : Ventilation! (2025)

Condensation in Australian roofs is a growing concern—especially as energy efficiency improves and roof spaces become tighter. In this video, we break down the role of vapour permeable wraps in managing moisture, protecting insulation, and extending the life of your building envelope. We compare vapour permeable membranes with non-permeable foil wraps, highlighting the risks of trapped moisture, especially in cooler climates or poorly ventilated roof spaces. You’ll learn best-practice installation tips, how to improve roof ventilation even above construction code, and why ventilation selection is critical to condensation control. 🔍 In this video: The science behind vapour permeability Why some foil wraps can trap moisture and create mould risk How roof ventilation and wrap selection work together Condensation management in Australian climate zones 🏠 Whether you’re building, retrofitting, or designing for performance—understanding roof wrap and ventilation choices is essential. We’ve published a follow-up to this video that dives deeper into important topics we didn’t cover here: 🐭 Vermin control for ventilated roof systems 🔥 BAL (Bushfire Attack Level) zone requirements and compliance 🎧 Acoustic performance of ventilated roofs vs Anticon 💧 Managing condensation risk and improving roof longevity 👉 Watch the full follow-up here: This update is essential if you're building in bushfire zones, humid climates, or comparing insulation strategies under the 2025 NCC!    • NCC Roof Ventilation Follow-Up: BAL Zones,...   00:00 Intro 00:47 Over Facia Vent 04:06 Ridge Vent 06:27 Tiles Roofs 12:02 National Contruction Code Requirements
