All FAQ
Is a cast iron airbrick suitable for use on a listed building?

Is a cast iron airbrick suitable for use on a listed building?

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.

Do your steel brackets have a protective coating?

Do your steel brackets have a protective coating?

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.

What building types is the H528 cast iron hopper head suited to?

What building types is the H528 cast iron hopper head suited to?

The H528 measures 760mm wide x 370mm deep x 565mm high, making it well suited to the largest properties in the range — substantial country houses, civic buildings and ecclesiastical projects.

How do I choose the right size rooflight opener for my rooflight?

How do I choose the right size rooflight opener for my rooflight?

Size selection depends on the distance between the mounting point and the rooflight frame, and the desired throw (opening distance).

For guidance on sizing for your specific rooflight, please call 0333 987 4452 or use the contact form.

What is LCC cast iron soil pipe?

What is LCC cast iron soil pipe?

LCC is traditional cast iron socket-and-spigot soil pipe made to BS 416-1:1990. Each length has a socket at one end and a spigot at the other, and joints are packed with caulking cord and finished with a jointing sealant. It is supplied with a black bitumen coating and is the like-for-like choice for external soil stacks on Victorian and Edwardian buildings. See the Traditional LCC range.

Is cast iron soil pipe suitable for listed buildings?

Is cast iron soil pipe suitable for listed buildings?

Yes. Cast iron is the original material for external soil stacks on most period buildings, and like-for-like replacement in cast iron is usually what conservation officers expect. Check with your local planning authority whether listed building consent is needed for the works.

Where should access pipes be fitted on a downpipe?

Where should access pipes be fitted on a downpipe?

At the foot of each stack above the shoe or gully, directly above offsets and bends, and below hopper heads where trees overhang the roof. On tall or long runs, an extra access point part-way up makes clearance easier.

What sizes are your cast iron airbricks available in?

What sizes are your cast iron airbricks available in?

Our cast iron airbricks are available in three standard sizes: 225mm × 75mm (single course), 225mm × 150mm (double course), and 225mm × 225mm (square format). These correspond to the standard airbrick positions used in Victorian and Edwardian brickwork. Each size is available across the School Board, Louvre, and Ornamental pattern ranges.

Do cast iron radiators work with heat pumps?

Do cast iron radiators work with heat pumps?

Yes, provided they are sized for the lower water temperature. Outputs are published at ΔT50; at ΔT30 a section gives about half that, so heat pump systems usually need more sections or a deeper pattern. We can prepare a radiator schedule at your heat pump design temperature.
