Ventilation

Good building practice dictates that any suspended ground floor requires ventilation. The NHBC recommends that the rate of ventilation is not less than 600mm² per metre of external wall. The combined air brick and ventilator supplied by CUBE6 provides a free vent area of 6600mm² and should be fixed at no more than 3 metre centres. Opposing external walls should have ventilation points to provide a free air path.

If another type of air brick (especially one made from clay) is to be used it may be necessary to increase the number of ventilation points.
