Cast iron square downpipes are the historically correct choice for Georgian and Regency buildings, and for any period property where a square section pipe was the original specification. The square profile has a more formal, rectilinear character than round downpipes — it was particularly fashionable from the late 18th century through the Regency period and remained in use on civic and institutional buildings well into the Victorian era. On stucco-fronted terraces, Regency villas, and formal town houses, the square pipe sits flush against the facade with a precision that round pipes cannot replicate.
The Square Pipe Eared is the standard eared cast iron square downpipe section, featuring integral ears cast into the pipe body for direct wall fixing. The ears allow the pipe to be secured to the wall surface without a separate bracket, giving a neat and period-appropriate fixing method consistent with original Georgian and Regency installations.
Available in three sizes: 75×75mm (3″×3″), 100×100mm (4″×4″), and 125×125mm (5″×5″). Supplied in primed or factory black finish. Manufactured in cast iron to BS 460:2002. Part codes: SQ3301E, SQ4401E, SQ5501E, XSQ3301E, XSQ4401E, XSQ5501E. For specification support, call 0333 987 4452.

The School Board Airbrick suits Victorian and Edwardian institutional, civic, and residential buildings where the square-grid airbrick pattern was standard — including school buildings, civic halls, estate housing, terrace houses, and warehouses. It is also appropriate on listed buildings and conservation area properties as a like-for-like replacement for worn square-grid cast iron vents.
Yes. Cast iron rainwater goods are widely accepted by conservation officers and historic environment bodies as the appropriate material for listed buildings. Tuscan Foundry's hopper heads are manufactured in solid cast iron to BS 460 specification and are suitable for all listed building classes. A linseed oil paint finish is also available, which is particularly appropriate for conservation projects.
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.
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
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.

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.
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.
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. 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.
Yes. The Brass Rooflight Pole Winder Opener 300mm is compatible with Lumen Rooflights and most timber-framed skylights. If you have a specific rooflight model, call 0333 987 4452 to confirm compatibility before ordering.
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.
