Condensation – Top Tips



Autumn is approaching and it’s that time of the year again – yes condensation is back!

Here are some simple tips to reduce condensation……….


  • When taking a shower or a bath, keep the bathroom door closed and if there is an extractor  fitted, make sure it’s on.
  • Don’t forget to pull the plug and drain the water out of the bath as soon as you’ve finished!
  • Drying clothes on radiators generates plenty of moisture, it will reduce condensation considerably if you use a tumble dryer instead and extract the moist air outside.
  • Modern windows have trickle vents fitted to allow a little air to keep condensation down, if these aren’t fitted, opening the window just a tiny bit will help reduce condensation
  • Hob extractors are great for removing moisture but only if they are set up to extract to an outside wall and they’re used every time the oven or hob is on. If they’re the recirc type then they won’t remove any moisture, just smells – consideration should be given to extracting outside if condensation is a problem in kitchens.
  • People generate moisture just by breathing so the more people in the property the more likely condensation will be a problem – public houses, village halls, community centres, offices and properties with large families are particularly vulnerable so ensure ventilation is adequate.
  • Fix leaks – Check inside the house to make sure there are no plumbing leaks. Particular attention should be given to overflows , double check that overflow pipework is connected to the outside and works. Checks drains aren’t leaking under the sink and under the bath.
  • Fix leaks – Check outside that rainwater gutters are clear and downpipes are connected and not blocked. When its raining hard, go outside and take a look to ensure the rainwater is flowing away from the property and not soaking into outside walls.
  • Put the heating on – warm air holds considerably more moisture than cold air but don’t be tempted to seal up the house by closing every window, see next tip……..
  • vent vent vent vent vent – we can’t stress this enough but ventilation is the key to reducing condensation, combined with improving insulation, reducing damp and heating the property.
Mr Chins House

Shipping All Over the World

After many years of supplying cast iron vents and drainage gratings it will come as no surprise to hear we ship all over the world.  One of our more remote deliveries has to be to Mr Chins House in Borneo, Malaysia. It was an order we especially remember because Mr Chin sent us a link to his blog showing the property and you can see from the picture above, what a surprise it was! Quite often we get photographs from customers and builders asking were they should put the vent or how to install it but normally the property isn’t at such an early stage as Mr Chins. It was very interesting looking at the way properties are built in the Jungle of Malaysia but what sounds so familiar is even in such a remote area Mr Chin had quite a job with the planners. Interesting but no matter were you are in the world, legislation is never far away!

One of the benefits of our new website has been the automation of global shipping rates. It has seen a significant increase in the number of overseas customers buying our British made products.

Throughout the website we showcase some of these customers and their properties including a wine cellar in Hungary and a windmill in Sweden as well as the many splendid properties at home in the UK.

To date our overseas customers include clients in Canada, Australia, New Zealand, Norway, Netherlands, Italy, Sweden, Hungary, Ireland, France, Spain, Germany, Switzerland and a substantial number of customers in many of the states in USA including Idaho, New Jersey, New Hampshire, Texas, Florida, Maine and Massachusetts.

Cast iron used for bridges, steps and walkways

Cast Iron for Steps, Bridges and Walkways

Cast iron has been used for centuries in properties for ventilation and drainage but it’s original use would have undoubtedly been in castles as covers for wells and as walkways and bridges. In more modern times, Georgians and Victorians used cast iron grilles along pavements to allow light through to the basement below and as bridges over streams and to create steps into properties.

We now find an increasing number of architects specifying not just the utilitarian square hole gratings  for steps and bridges but also the more decorative, Ecclesiastical and English Scroll  gratings for more elaborate projects.

Below, we feature an installation of gratings used as steps and a bridge over a small stream.  It’s an unusual combination, clients would normally require a step into a property or a walkway over a stream but not often both, but it illustrates the possibilities and the opportunities and benefits of using cast iron gratings.

Measuring for installation of cast iron gratings

The brick pillars or risers, when weathered, will blend in with the brick used around the window reveals of this stone outbuilding.

And then the gratings are fitted into the cast iron bearers onto the risers……….

In this example, the bearers are screwed into the steps and then covered with hardwood (below). Drilling is not always required, quite often, bearers are simply mortared in place – every installation is different! We have seen clients slot the gratings into rebates cut with a disc cutter into stone slabs or into existing concrete paths without using the bearers which is very effective.

Exporting to Sweden

Cast Iron Air Brick Outlet in Sweden

We’re proud to announce our cast iron air bricks and vents are soon to be available to property restorers and architects in Sweden.
Last week we were very excited to welcome a visit from Henrik Ulin, the owner and founder of Gamla Majeriet, the online building materials company based just south of Malmo, Sweden.

Henriks company specialises in quality building materials for the discerning property owner in Sweden and features many British made products. As well as our British made Conservation vents and Heritage vents, Gamla Majeriet also stock Thomas Crapper toilets, Drummond bath tubs (photographed) and various cast iron products including rainwater goods, bollards and radiators.

Of course it’s not the first time we’ve supplied to Swedish companies, our first Swedish customer were the owners of the wonderful Stavik lighthouse at Karlstad a number of years ago, but Gamla Majeriet will be our first retail outlet in Scandinavia.


British manufacturing – The New Micro Foundries

The Cast Iron Air Brick Company have been champions of UK made products for years. Our products are made in foundries of all shapes and sizes across the country from Somerset to Scotland. Many of these foundries have been producing iron castings since the 19th century, but our newest foundry is, by far, the most interesting. Situated in a tiny unit on an industrial estate, the little “micro foundry” supplies us with the 4″ and 5″ cowled cast iron Conservation vents. Our photograph (attached) features the entire workforce (yes both of them) turning out a crucible of molten iron to cast four of our Conservation vents.

To see more on the “micro foundry” and our vents being cast see the full story in pictures on Youtube, or view our foundry art section on Pinterest.


Supplying Windsor Air Bricks to Celebrity homes

In the 10 years or so we’ve been supplying cast iron vents and drainage gratings, we’ve supplied vents for all sorts of homes and they’ve been installed in “celebrity houses” such as Mrs Thatchers house, the colleges at Oxford and Cambridge, the PMs residence at Chequers and even Buckingham Palace!

We’re always thrilled when our vents are installed in these wonderful period properties and in the nations famous buildings.But there’s nothing to compare with our latest order for more than fifty of our beautiful Windsor air bricks (show picture of WIN3 ).

Our vents are not only going to be installed in one celebrity home, they’re being installed in an entire street of them! Around 40 homes in total and everyone of these homes is (and has been in the past) occupied by some of Britains most famous people (or should that be “Characters”). Where can it be?

Well, were else than Britains favourite street featured in Britains favourite TV programme, Coronation Street.

Conservation Vents – Before and After

Our cast iron Conservation vents are known as conservation vents for a reason. They’re ideal for use in conservation areas and especially suited to installation on listed buildings*. They can be used for outlets for extracted air from tumble dryers or fan outlets from bathrooms, kitchens and hobs or to supply air (up to 8000mm2) into a property for combustion appliances such as log burners and boilers. They are available in two spigot sizes either 4″, 100mm (7200mm2) or 5″, 125mm (8000mm2) diameters.

The picture before and after (attached) illustrates just what an impact our vents have in improving the look of ventilation outlets. Although especially suited to brick properties, our CON4 installed on this very tricky slatted wooden wall looks fantastic.
