3D Ventilation Block, also known as breeze block, is a type of 3D concrete block that is designed to allow for air circulation while still maintaining privacy and security.
Ventilation blocks come in a variety of shapes and sizes and are designed with various patterns and configurations that allow for different levels of airflow. Some blocks are designed with small openings that allow for a modest amount of air circulation, while others feature larger openings or perforations that allow for greater airflow.
