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.
Covid 19 update
Due to the Government’s instructions regarding the Coronavirus, CUBE6 will be closed until further notice. We all hope to return to normality as soon as possible.
We would like to take this opportunity to thank everyone for their business and hope you all stay safe. Best Wishes from all of us at CUBE6.
