How do I order a rooflight opener handle?

How do I order a rooflight opener handle?

Rooflight opener handles can be ordered directly through tuscanfoundry.com. For volume orders or project-specific queries, please call 0333 987 4452 or use the contact form on our website.

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.

What finishes are available on cast iron airbricks?

What finishes are available on cast iron airbricks?

Our cast iron airbricks are available in a choice of finishes including primer and painted options. If you require a specific finish for a conservation project or to match existing ironwork, please call us on 0333 987 4452 to discuss.

My house has a plastic guttering system. Can I use your brackets to replace my exisiting broken ones?

My house has a plastic guttering system. Can I use your brackets to replace my exisiting broken ones?

Our brackets are more commonly used on cast iron rainwater systems. Unlike plastic, cast iron is heavy and the weight keeps the gutter in position. As such our brackets do not normally have retaining clips which could lead to plastic or lightweight gutters blowing out of the bracket. The profile of your gutter should match that of our bracket but without the weight to keep it in place you may well encounter problems in bad weather.

What sizes are the Iron Works Patterned Hit & Miss Vents available in?

What sizes are the Iron Works Patterned Hit & Miss Vents available in?

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.

Please can you advise whether we will require 1/2″ or 3/4″ BSP connections for our new cast iron radiator.

Please can you advise whether we will require 1/2″ or 3/4″ BSP connections for our new cast iron radiator.

All of our cast iron radiators are availbale as standard with a 1/2″ BSP (15mm) connection. We are though also able to supply many of our radiators and valves with 3/4″ BSP connections. Due to the size proportions of some radiators and valves 3/4″ connections may be more suitable.

What building types is the School Board Airbrick suited to?

What building types is the School Board Airbrick suited to?

The School Board Airbrick suits Victorian and Edwardian institutional, civic, and residential buildings where the square-grid airbrick pattern was standard — including school buildings, civic halls, estate housing, terrace houses, and warehouses. It is also appropriate on listed buildings and conservation area properties as a like-for-like replacement for worn square-grid cast iron vents.

My builder has calculated out our heating requirement in each room of our house in BTU’s. Can you tell me what BTU’s stand for, and is this different to KW.

My builder has calculated out our heating requirement in each room of our house in BTU’s. Can you tell me what BTU’s stand for, and is this different to KW.

BTU stand’s for British Thermal Units. This was the old (Imperial) measurement for heat in connection with plumbing. Although BTU’s is a term still commonly used within the heating and plumbing, the industry is now going over to KW’s Kilowatts.

Do other materials offer the same benefits as cast iron?

Do other materials offer the same benefits as cast iron?

The drainage and guttering market has matured considerably over the past 20 years and there are now many more product choices for consumers to consider.

Despite the influx of new materials it appears that the benchmark for rainwater systems is still cast iron. Cast iron rainwater goods were introduced in the late 18th Century as an alternative to lead. As well as being easier to produce, the material enabled eaves gutters to be installed more simply, since lead could only be used in this location as a lining for timber gutters.

Many modern materials focus on replicating the appearance of cast iron but those materials can vary rarely offer any of the benefits. Cast iron gutters and pipes offer great strength and durability, a proven history of long life, low noise operation and fire resistance. Most old buildings have cast iron rainwater systems that should be maintained and preserved however; these inherent benefits make cast iron an ideal choice for both traditional and modern installations.

It is not uncommon to see modern alternative products marketed with terms like low maintenance or easy to install and cost effective. It has even been said that ‘plastic guttering systems provide a way of achieving a traditional look with modern convenience’. These terms tend to refer to possible cost savings rather than any real product benefits. It is also difficult to quantify the benefits of modern convenience over traditional build quality.

It is worth remembering that all rainwater goods will require some element of maintaining to ensure they are unblocked by debris and remain functional. No rainwater system cleans itself. Today most suppliers of cast iron rainwater systems offer products in both primer or pre-painted with a 10 year protective coating. When describing modern materials, the term ‘cost effective’ is used rather than simply saying cheap. There is no doubt that the initial cost of many modern materials is less than cast iron but you might be surprised to know that over its lifespan, cast iron will cost around a third of plastic.

It is easy to forget about your rainwater system but it does need to be maintained and inspected at least twice a year regardless of the product material. It does not matter whether the property is hundreds of years old or brand new, the message is the same; ‘maintaining your rainwater system contributes to the external appearance of the building as well as keeping it free from damp and structural damage.
