If the void has inside sleeper partitions, provision should be made for air flow to pass by way of those barriers and give safety, so as no part of the floor void is left to stagnate and become susceptible to moisture. As all manufacturers’ underfloor ventilators have different airflows, an open specification could result in using merchandise which give a lower fee of ventilation than initially meant leaving the sub-floor under ventilated. The Building Regulations Approved Document C states suspended timber flooring and suspended concrete floors (including block and beam) have a provision for air flow on two opposing external partitions of not lower than 1500mm² per metre run of external wall or 500mm² per metre² of flooring space, whichever works out to give the higher quantity of ventilation.
Sub Floor Ventilation – How Does It Work?
For instance, where the sub-floor area has the lowest clearance from the ground to the ground an Envirofan single-brick sub-ground ventilation system would exchange a vent beneath that specific space, whereby the extraction course of the humidity is drawn out and changed with fresh air. This then ingresses by way of other current passive vents.
