Firstly, Envirofan can induce dry air from outside and force it into the underfloor area by the use of solar powered ventilation systems, which are installed on the exterior wall (see picture below) or by the utilisation of wire mesh vents. We then use brick size ventilation systems that are established in the sub walls to direct air flow from room to room at a rate of 2.5m3/per minute at 27db. Then extraction ventilators, which are mounted on the other side of the home, preferably on the east or south aspect, draw the damp air out. This is the objective of what is deemed cross-flow ventilation. In exceptional circumstances, where there is no accessible exit point for an extraction system, the use of flexible duct to the nearest external point is unavoidable and is used sparingly.

So the conclusion is: for optimum cross-flow ventilaton, keep your sub-floor clear and use flexible ducting sparingly.
