About Our Air Bricks

Britannia has been manufacturing and supplying traditional cast iron and aluminium air bricks for the past 25 years to individuals and trade customers.

All of our air bricks are manufactured in the UK using traditional methods and are supplied from stock.

Our cast iron and aluminium air bricks are produced using a very similar process, the difference being that green sand is used for aluminium and furnace self-set sand for cast iron.

Our Britannia foundry is located in Hoddesdon, which is managed by Chief Engineer Russell who has 35 years’ experience in the industry.
