The louvre cast iron air bricks are almost exclusively used in external positions. The great advantage of this type of air brick is its ability to deflect driving rain and also to reduce the possibility of back draught in exposed conditions. Cast iron louvre air bricks are made from grey iron, cast in UK in sand moulds bonded with resin to a fine cast finish and are available in two sizes (9x6 and 9x9) The air brick is constructed from grey cast iron and is used for supplying natural ventilation to interior rooms and also as an extractor outlet vent grille over core drilled duct holes. In this instance the louvre air bricks are used as the terminal grille for fans extracting air from living rooms, kitchens, bathrooms,WCs and hob extractors.
