Sub Floor Ventilation – How Does It Work?
For instance, the place the sub-floor area has the bottom clearance from the bottom to the floor an Envirofan single-brick sub-floor ventilation system would substitute a vent underneath that particular area, whereby the extraction course of the humidity is drawn out and changed with recent air. This then ingresses through other current passive vents. This is where passive vents have their rightful place in building construction, to act as an air intake due to extraction by way of the Envirofan fan-compelled system.
