Frequently Asked Questions

  • What are passive wall vents?

    Passive wall vents are non-powered ventilation openings installed through an external wall. They allow air to pass naturally into or out of a property, helping to support background ventilation.

  • Can passive wall vents help with condensation?

    Passive wall vents can help improve airflow, which may reduce condensation in some cases. However, condensation can also be caused by poor extraction, high moisture levels, insulation issues or a lack of whole-home ventilation.

  • Do passive wall vents let in cold draughts in winter?

    Passive vents introduce outside air, so some cooler airflow may be noticeable during colder weather. Correct positioning and suitable vent selection can help minimise discomfort.

  • Are passive vents enough ventilation on their own?

    This depends on the property and its ventilation requirements. Passive vents may form part of a ventilation strategy but are not suitable as the sole solution for every building.
