The G935 Combination Cavity Sleeve should be fitted to the back of a G930 Combination Airbrick 9’’ x 3’’ and adjusted to fit the desired cavity width. It can be used in any combination required and built into the brick course as normal although care should be taken to keep the airflow passage clear from mortar droppings.
This product should be used in conjunction with other products from the Manthorpe range to provide a complete through wall ventilation system.
