Cast Iron Air Brick – Single (3 × 9 inch)




Cast Iron Air Brick – Single (3 × 9 inch)
• Material: Made from solid cast iron, these air bricks are cast using traditional methods for strength and longevity. Natural variations and minor surface textures are part of the process, giving each piece its own character.
• Design: Classic Single 3 × 9 inch format with a traditional grid design, providing effective airflow while preserving original period detail.
• Style advice from Mark: The Single 3 × 9 inch is a versatile choice for smaller walls, outhouses, or subtle elevations where you want the detailing to blend quietly into the architecture. It works especially well in Georgian and Victorian restorations where authenticity matters.
• Installation: Built directly into brickwork or blockwork during construction or renovation. Designed to sit flush within the wall as part of a ventilation system.
• Craftsmanship: Carefully handcrafted in a British foundry.
Finish Notes: Cast iron air bricks should generally be painted, ideally prior to installation, to protect them from rapid weathering. Left unpainted, the iron will quickly oxidise when exposed to the elements, developing a rich surface patina and an authentic, timeworn look that blends seamlessly with historic brickwork.
