The Ornamental Airbrick is most appropriate on Victorian Gothic buildings — churches, chapels, vicarages, almshouses, collegiate buildings, and high-specification estate architecture — where decorative ironwork was part of the original design. It suits listed building replacements in kind and heritage new build where period accuracy in detailing is expected.

The School Board Airbrick (F020801AFC) is available in three standard sizes: 225mm × 75mm, 225mm × 150mm, and 225mm × 225mm. These correspond to one-, two-, and three-brick-course heights and allow ventilation requirements to be met across a range of subfloor and wall opening sizes.

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.

Our cast iron airbricks are supplied in primed finish, ready for on-site painting. This allows them to be finished to match the existing ironwork or masonry colour of the building. Standard black gloss is the most common finish for conservation and heritage projects.

Yes. All our mild steel brackets are supplied in either silver or black zinc plate. This coating protects the metal however, both will need painting prior to installation.

We have chosen to use zinc plating for two reasons; firstly that it is a more environmentally friendly than galvanising and secondly that it does not block up the threaded part of the rise and fall cups in the way that galvanising does.

This opener is particularly well suited to period and heritage properties — Georgian and Victorian terraces, conservation area houses, traditional orangeries, and listed buildings where a brass finish is required to complement existing ironmongery. It is compatible with Lumen Rooflights and most timber-framed skylights.

Yes. Cast iron airbricks are frequently specified for listed buildings and conservation area properties precisely because they replicate the material and pattern of the original Victorian and Edwardian ventilation grilles. Local conservation officers and building control typically accept like-for-like cast iron replacements without objection. We can provide product specifications and material datasheets to support applications.

The louvre face provides directional airflow and offers some resistance to driven rain entering the subfloor void, making it a practical choice for exposed elevations or properties in areas with significant prevailing wind and rainfall. The square-grid (school board) pattern offers a larger open ventilation area but less weather protection.

Yes. Polished brass ironmongery is historically appropriate for period buildings and is generally acceptable to conservation officers for listed building projects. If you require confirmation for your specific scheme, we are happy to advise — call 0333 987 4452.

We manufacture a wide variety of brackets for many different cast iron gutter and pipe profiles. More common types are the rise and fall, top fix and side fix rafter and the holderbat or pipe clip.

We can also offer traditional drive brackets, repair brackets and fascia brackets in both steel and cast iron.

It is always advisable to replace like with like because quite often the brackets form and important part of the buildings architecture. Occasionally buildings have special decorative brackets and our UK manufacturing allows us to produce small quantities of bespoke brackets when required.
