U9 Black Silicone

£12.60 +VAT

Low modulas black silicone for common half round, ogee, deep half round, moulded G46 cast iron guttering and round pipes.

U9 Black Silicone is a low-modulus black silicone sealant formulated for jointing cast iron gutters and pipes. Low-modulus silicone remains flexible after curing, accommodating the thermal expansion and contraction that cast iron guttering undergoes through temperature cycles across the year without the joint cracking or losing adhesion. This flexibility makes it significantly more durable than standard frame or construction silicones on cast iron joints.

Supplied in black to match the standard factory black finish of cast iron gutters and pipes. Compatible with all standard cast iron gutter profiles: common half round, beaded half round, deep half round, moulded ogee, G46 moulded ogee, Notts OG, and No.46 moulded. Also suitable for ogee and moulded gutter joints where a flexible waterproof seal is required. For specification support, call 0333 987 4452.

Is a cast iron hopper head suitable for use on a listed building?

Is a cast iron hopper head suitable for use on a listed building?

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 grades. A linseed oil paint finish is also available, which is particularly appropriate for conservation projects.

What building types is the Iron Works Hit & Miss Vent in Antique Black suited to?

What building types is the Iron Works Hit & Miss Vent in Antique Black suited to?

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.

Are hit and miss vents suitable for listed buildings?

Are hit and miss vents suitable for listed buildings?

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.

Is a brass rooflight opener suitable for use on a listed building?

Is a brass rooflight opener suitable for use on a listed building?

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.

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.

Are ornamental cast iron vents suitable for listed buildings?

Are ornamental cast iron vents suitable for listed buildings?

What building types is the Pultney Tapered Hopper Head suited to?

What building types is the Pultney Tapered Hopper Head suited to?

The Pultney Tapered Hopper Head is well suited to Georgian and Regency townhouses, Victorian terraces, rural farmhouses, barns, and functional estate buildings where a plain, period-correct hopper is the appropriate specification.
