What Are External Grilles Used For?
External grilles are a crucial part of any ventilation system. Typically installed on the outside wall, they protect your ducting from potential harmful external elements like rain, pests, and debris while allowing air to flow freely in or out of the building. Whether you're installing an extractor fan for a bathroom, kitchen, or any where else you need one, using a quality external grille helps maintain efficiency and prolong the lifespan of your ventilation.
Types of External Grilles
Our collection includes plastic and metal grilles in various sizes and styles to suit your need. Choose from fixed louvre grilles, gravity grilles, and weatherproof hoods – all designed to prevent backdrafts and improve ventilation performance.
Need Help With Sizing or Installation?
When selecting parts for your ducting system, it’s essential to ensure all components are properly matched. For example, if you're purchasing a 150mm external grille, your ducting, inline fan, and connectors must also be 150mm in diameter to ensure a secure fit and optimal airflow. We stock external grilles in popular sizes like 100mm, 125mm, and 150mm, with product filters to help you quickly find the right fit. If you’re unsure about which grille you need, speak to one of our ventilation experts today!
