What building types is the Polished Chrome Rooflight Hand Winder Opener suited to?

What building types is the Polished Chrome Rooflight Hand Winder Opener suited to?

The polished chrome telescopic rooflight hand winder is suited to contemporary, Georgian-revival, and high-specification interiors where a bright chrome finish is required to complement existing ironmongery. It is compatible with Lumen Rooflights and timber-framed skylights.

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.

Are cast iron airbricks suitable for use on listed buildings?

Are cast iron airbricks suitable for use on listed buildings?

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.

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.

We are refurbishing our bathroom and wish to place a heated towel rail in the new bathroom. Our plumber has advised that the heated towel warmer would be connected to the heating system, this would mean when we turn the system off in the summer that the towel rail will not work. What can we do ?

We are refurbishing our bathroom and wish to place a heated towel rail in the new bathroom. Our plumber has advised that the heated towel warmer would be connected to the heating system, this would mean when we turn the system off in the summer that the towel rail will not work. What can we do ?

It is possible for us to supply towel warmers with an electric heating element in them. The Electrad system is a unique system available to us, that enables independent heating of towel rails and radiators via the properties electrical system.

What building types is the Paxton H82 hopper head suited to?

What building types is the Paxton H82 hopper head suited to?

The Paxton H82 is a large-format hopper with decorative collar mouldings, making it particularly well suited to late Victorian and Edwardian buildings where the rainwater system forms part of the architectural composition. Typical applications include commercial heritage buildings, civic buildings, large detached houses, institutional premises, and warehouse conversions where a more substantial fitting is appropriate.

How does a hit and miss vent work?

How does a hit and miss vent work?

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.

What finishes are available on your cast iron hopper heads?

What finishes are available on your cast iron hopper heads?

Cast iron hopper heads from Tuscan Foundry are available in Standard Black (a factory-applied primer and topcoat finish) and Heritage Colours. A linseed oil paint finish is also available, providing a vapour-permeable, historically authentic coating that is particularly appropriate for listed buildings and conservation projects. Full finish specifications are available from the team.

What is the difference between satin chrome and polished chrome rooflight openers?

What is the difference between satin chrome and polished chrome rooflight openers?

Satin chrome has a brushed, low-sheen finish suited to contemporary interiors, while polished chrome has a bright mirror finish. Both are available in the telescopic hand winder range at Tuscan Foundry. The choice typically depends on the existing ironmongery specification.

What building types is the Iron Works Patterned Hit & Miss Vent suited to?

What building types is the Iron Works Patterned Hit & Miss Vent suited to?

The Iron Works Patterned Hit & Miss Vent suits Victorian and Edwardian buildings where decorative cast iron or brass ventilation grilles were part of the original specification — including terrace houses, civic buildings, churches, entrance halls, and estate properties. It is appropriate on listed buildings and conservation area properties as a like-for-like decorative vent replacement, and on new heritage-quality construction where period detailing is required.
