Important

Air bricks are designed to allow air to flow either in or out for the purpose of ventilation. So, when comparing air bricks remember not to look just at the design but also the free air flow of the air brick - If good air ventilation is essential choose an air brick with a high free air flow. 

 




 Installation

Most of our cast iron air bricks should be suitable for listed properties (subject to conservation approval) and should  be ideal modern replacements for defective and missing grills in restoring many other Georgian, Victorian and Edwardian properties.

Period Property Extensions

- Extensions to Georgian, Victorian and Edwardian properties deserve sympathetic care and treatment so your extension works in harmony with the existing building. 

Your building control will insist you meet modern ventilation requirements and may expect vent fans in kitchens, cloak rooms and bathrooms. The conservation department will be more concerned with how it looks - the cast iron reproduction vents should appease both parties.

Please check individual product web pages to see full specifications and product free air vent flows.

New Ranges

We are always evaluating our products and looking for designs that will compliment period properties.

The 6inch x 6 inch drilled vent grille above is ideal to cover 110mm outlet ducting from bathrooms and kitchens and looks infinitely better than the modern plastic grilles installed by new build developers.

Heavy Duty Range

The heavy duty 9" x 3" Cast Iron vents weigh nearly 2KG and the 9" x 6" and 9" x 9" even more. They are up to 1/2 inch thick in places and therefore should last several lifetimes, but all that metal comes with a price; They have a much lower free air flow rate than simpler designs so if good air flow is important, fit plenty of these air bricks or choose another design.

Square Hole and Vertical Slotted Range

Almost exact replicas of Victorian and Edwardian utility square hole air bricks and slotted grilles, these ranges are relatively lightweight but have excellent flow rates for good ventilation.

Rodents and Insects
Fly Screen Cast iron Air Bricks and Vents

If mice or rats are a problem or flies are getting into your home via your air vents then there is a solution.
Fit a fly screen cast iron air brick to ensure your house is safe from unwelcome visitors.



Fly Screens are a copper or phosphor bronze mesh designed to exclude pests but allow air through for ventilation.  The mesh is washable and can be removed from the air brick by unscrewing the removable front.  Fly screens are also fitted to a select number of vent grilles and are held in place by the screws attaching the cast iron grille to the wall (screws not supplied).

Please Note:- It is not possible to put mesh behind a standard air brick.  This is because the mesh will become clogged with dirt very quickly and prevent the air brick from working, blocking the air flow. The mesh must be able to be removed for cleaning and the only way to do this is to have an air brick with a removable front , as above.  These air bricks are available on our website  in 3 sizes, 9x3, 9x6 and 9x9 as items FLY3, FLY6 and FLY9.
