Meticulously engineered to suit both interior and exterior applications. Designed to optimise airflow, these vents effectively cool roof spaces in summer while curbing dampness and mould growth in the winter months. Installed directly under the eaves—the overhanging section of a roof that extends beyond the walls of a house—they allow fresh air to enter the roof cavity, creating a continuous airflow when paired with roof-mounted ventilation systems like Whirlybirds. This airflow helps expel heat, moisture, and stale air from the roof space, reducing the risk of condensation, mould, and dampness, while also keeping pests like insects out through their perforated design.
Constructed from 0.9 mm-thick white powder-coated aluminium, they are robust and durable, ensuring long-term performance. Recognised for complying with fire rating requirements as stipulated in AS3959-2009 up to BAL40, these vents also meet the NCC 2022 10.8.3 compliance criteria, reinforcing their reliability and safety. Each vent provides an expansive open area of 26,250 mm2, maximising ventilation efficiency and helping maintain optimal building standards. With their ability to regulate airflow effectively and enhance indoor comfort, these vents are an ideal air intake solution for any property.
