Grid9 Air Brick


9 x9 Square Hole Air Brick with choice of finishes, bare as standard or painted black ( £10).

Although not as efficient as the MAX9 cast iron air brick, the GRID9 is especially suited to period properties requiring a little less ventilation. It has been used in National Trust properties and most noticeably in the National Monument of Nelsons flagship, HMS Victory
