  • Aquwall Press

    The Aquwall Press is an easy to install, pressure controlled, passive external wall vent. The Aquwall Press will automatically regulate incoming airflow to avoid overventilation during periods of high wind.

    The Aquwall Press will restrict the incoming airflow based on the pressure of incoming air, if pressure of airflow is too high the vent will restrict and only provide the required ventilation rate.

    Acoustic duct mounted silencers are available to reduce noise ingress from outside and provide a more comfortable indoor environment. The Aquwall Press silencers are available in both melamine and polyester to suit the equivalent area requirements. Both options provide an equivalent area in excess of 2,500mm2 to ensure full compliance with TGD Part F.

    The Aquwall Press is suitable for both new build and retrofit projects on exposed sites where high winds can be an issue.

  • Click 3000 PVC

    When you want the neatest finish to your PVC windows the airvent click PVC is a superb choice. The vent comes complete with sleeve and collar for easy installation and springs into action with a simple touch.
