4” pipe outlet
Cowled universal roof vent.
Designed for roof space ventilation and mechanical extraction/ soil stack termination.
Designed to provide a quick and simple solution to the problems of roof space ventilation and mechanical extraction/ soil stack termination through a wide variety of roof coverings. It is especially useful on jobs where the installer may not know what the roof covering is.
Designed to suit both large and small format interlocking tiles, both flat and profiled in design, including deep bold roll styles of tile. The vent is fitted with a versatile flashing skirt which can be dressed to match the relevant profile of the roof covering and comes with an adhesive mastic backing which securely seals the flashing down to the roof.
The hooded cowl protects the opening from the elements whilst providing an airflow path into the roof space. An integral 4 mm louvred grill within the cowl prevents the entry of debris and large nesting insects.
When using the vent for mechanical extraction or soil stack/ vent pipe termination, the lower outlet is stepped to allow for 4", 5" or an oval 6" connection. The 4" connection can be joined to one of the Manthorpe range of GRPA Flexible Pipes to continue the ducting further into the roof space.
