Cement Breeze Blocks, often called Screen Blocks or Ventilation Blocks, are available in many colors, and ideal for separating and defining spaces while providing sun protection and maintaining openness and airflow. Please note that breeze blocks are decorative, and should not be used as structural units, such as in load-bearing walls.
Solid concrete blocks being larger in size weigh more than the bricks and are a little difficult to handle. However, hollow and porous cement blocks are lighter in weight and are easier to work with. Concrete blocks are more durable and can carry heavy loads as compared to bricks.
