The Panel Vent consists of a matrix of air passages. Each air passage has internal dimensions of 146mm by 146mm (X and Y axes respectively), and the Z axis dimension is made to be the same as the thickness of the wall. It is evident that more or fewer air passage columns, and/or rows can be used depending on ventilation requirements. The 146mm by 146mm openings are too small for even a child’s head to go through, and are lined with steel plates welded together, which are in effect permanent shutters. The spaces around the air passages are filled with 60 MPa reinforced concrete. The final construction is extremely strong and robust.
