Suitable for providing a ventilation inlet or outlet for extraction systems in new cavity brick walls.
The thru...air product is designed to provide a ventilation outlet or inlet using a 4 or 5 or 6 inch telescopic pipe to a Manthorpe single, double or triple airbrick. Each thru...air unit allows for an extraction system to be conveniently built into the brickwork, eliminating the need for retrospective core drilling. The telescopic element allows the installer to extend or reduce the length of the pipe to suit the thickness of the wall and ducting connection.
During installation, if required the detail can be finished off with a suitable cavity tray (including weep vents) above the product to prevent water ingress.
