A genuine half round beaded cast iron rainwater system with double beading.
The beaded half round cast iron gutter sample allows you to verify the profile, finish, socket dimensions, and material quality before committing to a full specification. The beaded half round is the traditional guttering profile across Scotland and northern England — the double bead along both lips of the gutter section is a defining feature of period architecture from Edinburgh and Glasgow to Newcastle and Leeds, and matching it exactly matters on a conservation or listed building project.
Order a sample to confirm that the Tuscan Foundry beaded profile is compatible with your existing installation, to compare against a surviving section before ordering a replacement run, or to present to a client or conservation officer as part of a specification approval process.
Supplied as a short length in factory black finish. For a full quotation or specification support, call 0333 987 4452.

Yes. The polished chrome telescopic rooflight hand winder opener is compatible with Lumen Rooflights and most timber-framed skylights. Call 0333 987 4452 to confirm compatibility with a specific rooflight model.
The Antique Black finish suits Victorian, Edwardian, and inter-war buildings where ventilation ironwork was painted rather than polished — estate houses, terrace housing, civic buildings, and rural properties. It is also correct for listed buildings and conservation area properties requiring like-for-like replacement of original ornamental cast iron vents.
We do offer a range of Ogee patterned gutters in both straight and radius profiles. The straight profiles are much more common and as such cost less.
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.
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.
Prices are shown on each product page for both sizes and all three finishes. For project quantities, specification support, or conservation enquiries, call us on 0333 987 4452 or use the contact form on our website.
A hit and miss vent has a sliding plate on the back of the grille that can be opened, partially restricted, or closed entirely without removing the vent from the wall. This allows airflow to be controlled from inside the building, making it suitable for underfloor void ventilation and through-wall ventilation where adjustable airflow is needed.
Yes. Cast iron ornamental vents in period patterns are frequently specified on listed buildings and conservation area properties as like-for-like replacements for original Victorian ironwork. Conservation officers generally accept cast iron in period patterns without objection. We can supply specifications to support planning and listed building consent applications.
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.
