Our cast iron airbricks are available in three standard sizes: 225mm × 75mm (single course), 225mm × 150mm (double course), and 225mm × 225mm (square format). These correspond to the standard airbrick positions used in Victorian and Edwardian brickwork. Each size is available across the School Board, Louvre, and Ornamental pattern ranges.
Available in two sizes: 225mm x 82mm (single airbrick course height) and 225mm x 150mm (double course height). Both sizes fit standard brick coursing positions and install flush into the wall face.

Yes. Cast iron hopper heads are the historically correct choice for listed and period buildings, and a like-for-like cast iron replacement is generally accepted without objection by conservation officers. We manufacture to BS 460 for genuine heritage character and durability.

Yes. Cast iron airbricks are the appropriate material for listed buildings and conservation area properties where the original ventilation grilles were cast iron. They maintain the character and material authenticity required by most conservation officers and listed building consent conditions. We recommend confirming the specific pattern with your conservation officer before ordering.
At the foot of each stack above the shoe or gully, directly above offsets and bends, and below hopper heads where trees overhang the roof. On tall or long runs, an extra access point part-way up makes clearance easier.
