Cast Iron Air Bricks Double Brick Sized (nom 9x6 inch)

Cast iron air bricks are ideal for installation in period properties and building renovation. They are made from grey iron, cast in sand moulds to a fine cast finish and can be supplied bare or painted. Mainly for exterior use, the double air brick can be used to provide air under suspended floors, for room ventilation to reduce condensation or provide combustion air for solid fuel appliances. The air bricks are mortared into the walls in the place of two bricks and designed to sit flush with surrounding brick work. The double air brick is often used in larger properties to provide additional ventilation for reduction of condensation and damp. Here we look at the eight different types of double air bricks commissioned by us from English and Scottish foundries

Cast Iron Air Bricks Single Brick Sized (nom 9x3 inch)

Mainly used as an exterior air brick in the place of a clay brick. The single air brick can be used to provide air under suspended floors and for room ventilation to reduce condensation or provide combustion air for solid fuel appliances. . One of the simplest and our earliest design is the grid pattern air brick. It was a design used during Georgian and Victorian period and its no surprise that weve supplied many fine and glamorous properties across the country (including Royal crescent, Bath) as well as hundreds of simple single fronted terraced houses. Weve supplied the REG3 for Maccreanor Lavingtons restoration of a Bastwick street property in London. The MAX3 with 7800mm2 free area of ventilation is our most efficient single air brick as its name suggests.

Cast Iron Air Bricks Triple Brick Sized (nom 9x9 inch)

Here we look at the seven different types of our largest triple air bricks and the 12 x 6 inch. Mainly used as exterior air bricks for large properties and commercial buildings, the triple air brick is predominantly used to supply room ventilation especially for combustion of solid fuel appliances and to reduce condensation. They are also suitable for use as extractor ventilation grilles from kitchens and exhaust grilles for restaurants and commercial premises.

Cast Iron Channel Drainage

The Quatrefoil cast iron gratings are exclusive to the Cast Iron Air Brick and although they can be used vertically for ventilation they are more often used as Drainage gratings in conjunction with the Manthorpe plastic channel. These are often specified to create elegant drainage and landscaping along paths and pavements of feature gardens and around fountains and pools. This design is an authentic reproduction of quatrefoil symbol found in many gothic churches across Europe and in Paris and Florence. It is therefore fitting that it was chosen to drain surface water along the steps of the entrance to the Italian garden in Hyde Park, London. This has been part of the Royal parks renovation scheme and is Grade2 listed by Historic England.

Cast Iron Coal Hole Covers

As the name suggests, these coal hole covers are brand new castings suitable to either replace worn or damaged existing covers or to install as dummies along pedestrian walkways. Our coal hole covers are standard imperial coal hole size which is 12 inches across (300mm diameter). They are often seen along high streets, especially in London along walkways and pavements and are even seen as dummies to give the impression that they are original and this is particularly effective in recreating period shopping centres and mews. Coal hole covers are available as solid or ventilated covers complete with frame. We also sell the cover or frame separate.

Cast Iron Conservation Cowled Vent

Mainly used as an exterior vent to extract damp and moist air from inside a building. Hob extractors, kitchen extractors, cloakrooms, wc, bathrooms, ensuites and tumble dryer outlets are the main uses. It does suit period properties although its quite a statement piece even on contemporary buildings. It has been used on a significant number of listed buildings and properties in conservation areas. The conservation vent has been instrumental in improving extractor efficiency as installers have been able to extract close to where the fan is positioned whereas in the past theyve ducted metres and metres of flexi pipe to terminate on a back wall to comply with building consent. It can also be used as an interior vent to allow air in for combustion especially with regards to stoves.

Rather than replacing ugly plastic metric air bricks when the builders have gone with the Windsor cast iron its far easier, more cost effective and creates a much better impression with clients to install them during the build. They are available in just one size but are interlocking and are predominately used singularly, double or triple. Our metric Windsor air bricks are the only cast iron air bricks fully interlocking with modern metric cavity wall sleeves and periscopes and are exclusive to the cast iron air brick company.

We've replicated cast iron square hole grilles for Kier constructions restoration of the 13th century college of Peterhouse at Cambridge university and other more recent buildings across the country. Cast iron made to measure grilles are cut to order from 3ft long grey iron grilles we have in stock. Using these grilles (nine different widths) we then cut them to create over 250 different sized grilles. We can supply them drilled or undrilled in the corners, with or without copper fly screen and paint them before delivery. The made to measure grilles are normally ready for dispatch the following week after the customer has placed the order.

Cellar, Basement, Soil and Sewer Vent

Cast iron stand alone vent, used for centuries in properties around the country and now very much in vogue. This charming vent has two functions, either to connect to the stack of a sewar pipe to prevent loss of water traps when WC are flushed or to allow air down into cellars and basements. The sewar vent function prevents smells escaping from sewars by an ingeneous and simple non return brass flap fitted onto the removable front panel. For basement and cellar ventilation this flap is replaced with mesh to allow a flow of air in either direction. Both options use the same cast iron cellar/soil vent body with 4" (100mm) spigot and are available with aluminium or brass front plates.

One of the farms that might be especially familiar to many is Emmerdale Farm, the fictional TV soap on ITV whose cobbled streets are now drained using one of our 12 cast iron slotted grilles. Larger properties, especially Georgian and Victorian manor houses had numerous round grilles fitted when they were built and we see a number of like for like replacements.

Using Cast Iron Imperial 9x3 Air Bricks with Metric Cavity Wall Duct and Periscope

Imperial air bricks are about the size of a Victorian brick which is around 9 x 3 inch or 225 x 75mm. They are quite a bit smaller than a metric air brick which is 8 ½ x 2 ½ inch or 213 x 66mm. The Cast Iron Air Brick Company have therefore designed an aluminium adapter to convert the metric duct so it will engage with many of the imperial air bricks we have. We call the adapter the metimp the name which conveniently translates to metric imperial. It is essential to use the adapter to connect all our 9x3 air bricks to metric ducting where the air brick doesnt have a cutaway frame. Please see the specification guidance for full details of each design.
