The Ornamental Airbrick (OAB) is available in three sizes: 225mm × 75mm (2.8kg), 225mm × 150mm (4.1kg), and 225mm × 225mm (5.8kg). All sizes have a uniform depth of 75mm, making them consistent to install across a subfloor ventilation course.

A genuine cast iron rainwater pattern orignally used in and around Nottingham, hence Notts Ogee. The profile is only available in the one size (4.5″) and has a flat base unlike the more traditional ogee (OG) curved pattern.
The cast iron Notts OG 135 degree angle provides an obtuse corner fitting for the Notts Ogee profile, handling bay windows, canted elevations, and building corners that require an obtuse turn. The asymmetric front face of the Notts OG is maintained through the fitting, preserving the profile’s character throughout the run on Nottingham and East Midlands period properties.
As with all Notts OG fittings, the 135 degree angle is handed — internal and external variants exist, and the asymmetric profile means fittings cannot be reversed to suit a different configuration. Identify the correct internal or external type for your application before ordering.
Manufactured in solid cast iron to BS 460:2002. Single size 115mm (4.5″). Supplied in primed or factory black finish. Commonly specified on Victorian bay-fronted terraces, villa-style houses, and civic buildings throughout Nottinghamshire, Derbyshire, Leicestershire, and the wider East Midlands where the Notts OG is the original and historically correct profile.
Compatibility: Notts OG cast iron gutter 115mm (4.5″) only. For specification support, call 0333 987 4452.

Yes. A polished brass finish is historically appropriate for period buildings and is generally acceptable to conservation officers for listed building projects. If you are unsure about the specification requirements for your project, we are happy to advise — call 0333 987 4452.
Yes. Decorative cast iron and brass ventilation grilles of this pattern were widely used in Victorian and Edwardian buildings, and like-for-like replacements are generally accepted by conservation officers for listed building works. We can provide product specifications and material details to support listed building consent applications if required.
Size selection depends on the distance between the mounting point and the rooflight frame, and the desired throw (opening distance). Our telescopic openers are available in 150mm, 250mm, and 300mm; the screw-jack stay is available in 300mm with a 250mm throw. For guidance on sizing for your specific rooflight, please call 0333 987 4452 or use the contact form.

The standards for our cast iron gutters and pipes have remained remarkably constant for many years. The physical properties of cast iron are sustained throughout its lifetime thus maintaining its effectiveness. Coupled with is durability and proper maintenance, we would expect our traditional cast iron rainwater products to last for over 50 years under normal conditions.
The drainage and guttering market has matured considerably over the past 20 years and there are now many more product choices for consumers to consider.
Despite the influx of new materials it appears that the benchmark for rainwater systems is still cast iron. Cast iron rainwater goods were introduced in the late 18th Century as an alternative to lead. As well as being easier to produce, the material enabled eaves gutters to be installed more simply, since lead could only be used in this location as a lining for timber gutters.
Many modern materials focus on replicating the appearance of cast iron but those materials can vary rarely offer any of the benefits. Cast iron gutters and pipes offer great strength and durability, a proven history of long life, low noise operation and fire resistance. Most old buildings have cast iron rainwater systems that should be maintained and preserved however; these inherent benefits make cast iron an ideal choice for both traditional and modern installations.
It is not uncommon to see modern alternative products marketed with terms like low maintenance or easy to install and cost effective. It has even been said that ‘plastic guttering systems provide a way of achieving a traditional look with modern convenience’. These terms tend to refer to possible cost savings rather than any real product benefits. It is also difficult to quantify the benefits of modern convenience over traditional build quality.
It is worth remembering that all rainwater goods will require some element of maintaining to ensure they are unblocked by debris and remain functional. No rainwater system cleans itself. Today most suppliers of cast iron rainwater systems offer products in both primer or pre-painted with a 10 year protective coating. When describing modern materials, the term ‘cost effective’ is used rather than simply saying cheap. There is no doubt that the initial cost of many modern materials is less than cast iron but you might be surprised to know that over its lifespan, cast iron will cost around a third of plastic.
It is easy to forget about your rainwater system but it does need to be maintained and inspected at least twice a year regardless of the product material. It does not matter whether the property is hundreds of years old or brand new, the message is the same; ‘maintaining your rainwater system contributes to the external appearance of the building as well as keeping it free from damp and structural damage.

The School Board Airbrick is suited to Victorian and Edwardian terraced housing, mid-century school buildings, civic halls, public baths, and converted institutional buildings. Its plain square-grid face matches the utilitarian aesthetic of late-Victorian construction and is also appropriate for new heritage-style builds in conservation areas.
