Superior Sub-Floor Ventilation Installation Methods

Sub- floor Ventilation companies usual practice is to use of flexible ducting (flexiduct) to various parts of the Sub-floor area. It is like an 'octopus' kind configuration. This design just puts more materials into the Sub-floor space which is just another obstacle for airflow to travel around, besides the brick piers, plumbing pipes and sub-walls. Envirofans Sub-floor Ventilation methodology does leave other Sub-floor 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 Sub-floor Ventilation problem area, we would install a Sub-floor 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 Sub-floor 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 Sub-floor Ventilation System. If the ground clearance is higher than the internal floor level, Envirofan Sub-floor Ventilation Systems has also got it covered there as well.
