Air bricks are small rectangular objects made of clay, concrete or plastic that contain small holes and are integrated into the structure of a building to allow air to circulate through the walls and floors. They are typically located at the bottom of exterior walls and under floors, where they help ventilate crawl spaces and prevent the buildup of moisture, mold and other harmful pollutants. Air bricks also help maintain a healthy level of air circulation throughout a building and prevent the accumulation of stale or damp air.
