204 x 60mm Slimline Horizontal Louvre Airbrick (Brown)

This low-resistance airbrick has been designed to comply with the latest Building Regulations Approved Document F, which requires ventilation outlets to provide a free area equivalent to at least 90% of the ductwork cross-sectional area. A single airbrick is easier to install than a double airbrick and offers greater flexibility in positioning.

Suitable for use with 100 mm and 125 mm diameter round ducting, as well as 204 × 60 mm rectangular ducting, the airbrick features integral guide vanes that help align the ducting with the spigot for quicker, easier installation.

For first-fix applications, a 500 mm length of 204 × 60 mm ducting is available, ensuring duct connections remain accessible once building works have been completed.
