Slimline Airbrick with Internal Damper 204 x 60mm Terracotta

Available in various colours, this low resistance air brick has been designed to comply with the latest Building Regulations Approved Document F, which requires a ventilation outlet to achieve a minimum of 90% of the cross sectional area of the ductwork. Installing a single air brick is much simpler than a double air brick and offers more versatility for locations. Suitable for 100mm and 125mm diameter and rectangular 204 x 60mm ducting. Attaching duct to the air brick is simplified by the use of guide vanes which help locate the duct onto the spigot. A 500mm section of 204 x 60 duct is available for first fix which ensures that connections are accessible after completion of building works. Colour options ensure that the low resistance air brick will be a match for almost any application.
