Superior Sub-Floor Ventilation Installation Methods
Sub- floor Ventilation companies usual practice is to use of flexible ducting (flexiduct) to various parts of the Subfloor area. It is like an 'octopus' kind configuration. This design just puts more materials into the Subfloor space which is just another obstacle for airflow to travel around, besides the brick piers, plumbing pipes and sub-walls. Envirofans Subfloor Ventilation methodology does leave other Subfloor Ventilation companies in its wake as we believe this is not good practice. It is our policy, that the use of flexi-duct should at all times, be used sparingly.

Where there is a Subfloor Ventilation problem area, we would install a Subfloor Ventilation System right at this point, in the exterior wall as shown in the illustration above and induce dry air from the sunny aspect of the dwelling. This can be achieved by the Envirofan Subfloor Ventilation System or by the installation of hi-flow vents. If there is a reduced external ground clearance to the finish floor level inside the home, then we would use a brick size Subfloor Ventilation System. If the ground clearance is higher than the internal floor level, Envirofan Subfloor Ventilation Systems has also got it covered there as well.
