The Ornamental Airbrick is a decorative cast iron ventilation grille produced in a Gothic foliate pattern — a design closely associated with the high Victorian aesthetic that dominated ecclesiastical, collegiate, and civic architecture from the 1850s through to the 1890s. Where the louvre and school board patterns prioritise utility, the Ornamental Airbrick is a statement piece: a grille that is meant to be read as part of the decorative programme of the building rather than as a purely functional element.
The face presents an interlaced foliate pattern derived from Gothic tracery — pointed arches, leaf forms, and interlocking curves filling the grille area within a moulded outer frame. The casting has good surface definition, with the foliate relief clearly legible at typical viewing distances. Available in three sizes — 225mm × 75mm, 225mm × 150mm, and 225mm × 225mm — it fits standard airbrick positions in brick coursing, with drilled fixing lugs to each face for solid bedding into masonry.
The Ornamental Airbrick is most naturally specified on Victorian Gothic buildings: churches, chapels, vicarages, school buildings, almshouses, and estate architecture where decorative ironwork was part of the original specification. It is also appropriate on listed buildings and conservation area properties where an existing ornamental grille is being replaced in kind, and on high-specification heritage new build where the client expects period accuracy in the detailing rather than a plain functional alternative.
UK-cast in solid grey iron and supplied in your choice of finish. For conservation officer-approved specifications, listed building projects, or to discuss suitability, call 0333 987 4452.
Our cast iron hopper heads are available with 65mm, 75mm and 100mm round outlets, 75mm, 100mm and 125mm square outlets, and 100x75mm, 125x100mm and 150x125mm rectangular outlets, to match the downpipe already on site or specified for the project.

Yes. Cast iron is the original material for external soil stacks on most period buildings, and like-for-like replacement in cast iron is usually what conservation officers expect. Check with your local planning authority whether listed building consent is needed for the works.
The Gothic foliate tracery design of the Ornamental Airbrick provides a good free-flow ventilation area relative to its face size. The open area is comparable to other standard cast iron airbrick patterns. The visual density of the pattern at a distance reads as solid ironwork, which suits formal and decorative elevations without compromising subfloor ventilation effectiveness.
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.
Our cast iron hopper heads are available with 65mm, 75mm and 100mm round outlets, 75mm, 100mm and 125mm square outlets, and 100x75mm, 125x100mm and 150x125mm rectangular outlets, to match the downpipe already on site or specified for the project.
Yes, provided they are sized for the lower water temperature. Outputs are published at ΔT50; at ΔT30 a section gives about half that, so heat pump systems usually need more sections or a deeper pattern. We can prepare a radiator schedule at your heat pump design temperature.
Half round gutter has a simple semicircular profile and is the most widely used pattern across all building types and periods. Ogee (OG) gutter has an S-shaped decorative profile, historically associated with Victorian and Edwardian properties. Moulded ogee profiles, such as the G46 and Regent No.16, have a more elaborate cross-section with additional mouldings and are typically found on larger or more architecturally significant buildings. The correct choice depends on what is already present on the building and any requirements set by a conservation officer.
