H25S – Large sand cast socket and spigot box guttering.
This large cast iron box gutter is suitable for larger
buildings and industrial and railway heritage projects, and is available in
the following sizes:
150 x 150mm
The TFH25S is a large sand cast socket and spigot box gutter in the 150×150mm size — a square-sectioned profile providing substantial drainage capacity in a form suited to parapet gutters, valley gutters, and other applications where a concealed or near-flush cast iron gutter is required rather than an exposed decorative profile.
The 150×150mm section makes the TFH25S one of the larger box gutter profiles in the range, appropriate for buildings with significant roof catchment areas and where the drainage load demands a very large cross-section. Typically specified on large Victorian civic buildings, churches, industrial heritage sites, and estate buildings.
Sand cast iron, manufactured to BS 460:2002. Supplied in grey primer or black painted finish. Lead times are typically 8–10 weeks. Contact Tuscan Foundry Products to discuss your project requirements before ordering.
Suitable for: Parapet and valley gutters, large civic buildings, churches, industrial and estate heritage. Call for price: 0333 987 4452.

Yes. Cast iron hopper heads are the historically appropriate choice for listed buildings, and are generally preferred by conservation officers and local planning authorities over modern plastic alternatives. Tuscan Foundry cast iron hopper heads are manufactured in solid grey iron and are suitable for use on listed buildings and within conservation areas. A linseed oil finish is also available, which is particularly appropriate for sensitive heritage projects.
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.
Casting of iron is an imperfect processs. It is possible with some cast iron radiators that you will get minor imperfections in the surface finish. When radiators are painted this will reduce and over the years every additional coat of paint applied will provide a smoother more equal finish.
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.
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.
The Antique Black cast iron version is suitable for external use. The Polished Lacquered version is best suited to interiors or sheltered external locations where the polished finish will be protected from weathering. The Polished Brass version is suited to interior and semi-exposed locations. For external applications on exposed elevations, the Antique Black finish is the recommended specification.
The Ornamental Airbrick is suited to Victorian villas, bay-fronted terraces, Gothic Revival institutional buildings, church halls, and civic buildings where decorative ironwork is part of the architectural language. It is also appropriate for listed buildings and conservation area properties where the airbrick is on a prominent elevation and the ventilation grille is expected to carry decorative character.
