HighFlow™ Ventilated H3 LVL Cavity Battens – NCC 2025 Ready

Highwood Timber’s HighFlow™ Ventilated H3 LVL Cavity Battens are engineered to provide superior moisture management, structural performance, and compliance with the upcoming NCC 2025 condensation requirements. Designed specifically for modern Australian construction, HighFlow™ battens create a continuous ventilated cavity behind external cladding systems, allowing moisture to drain and air to circulate freely.

As Australian homes become more energy efficient and airtight, effective condensation management is essential to prevent mould growth, timber decay, insulation damage, and costly structural repairs. HighFlow™ cavity battens help builders and architects meet evolving National Construction Code (NCC) requirements while delivering healthier, longer-lasting buildings.

Key Benefits
NCC 2025 Compliance Ready E2/AS1(NZ) standards
