Three World-First Innovations
The only cavity vent system that combines active moisture removal, quality control, and cross-ventilation
Wind-Powered Suction
Harnesses wind energy to actively pull moisture out of cavity walls - not just passive drainage
Removable Insert
World's first inspectable cavity vent - verify installation, check for blockages, prove compliance
Cross-Ventilation
Creates continuous air exchange through cavity walls — replacing moisture-laden air with fresher air so walls dry naturally

Unlike traditional passive vents, Active Vent uses wind power to create negative pressure that actively pulls moisture out of cavity walls
Stop Damp at the Source — With Natural Cross-Ventilation
Most damp, condensation and mould starts the same way: humid air with nowhere to go, settling on cold surfaces until it soaks into the wall. Active Vent uses the power of the wind to draw fresh air in and push stale, humid air out — so moisture leaves before it can cause damage.

The World's First Wind-Powered Cross-Ventilating Vent
Ordinary vents only let air in or out. Active Vent is engineered — and patent-protected — to do both from a single unit, using natural wind pressure for continuous airflow with no electricity, no noise and no running costs.
