A Ventis Subfloor System works by creating a ventilation flow in the subfloor area. We do this using a fan unit to introduce fresh outside air in and expel subfloor air out.
The number of fan units can change based on the area and the levels of moisture present. Upon a home visit, a Ventis technician will specify the best solution for your home.
Depending on the lay of the land under your home, water may pool after rainy weather, and then slowly evaporate and rise into the home. Ventis Subfloor Ventilation effectively ventilates and expels this moisture, however you may need to look at solving the problem with drainage solutions to prevent water pooling in the first place.
With the addition of decks and increased vegetation from gardens and shrubs, the natural cross-flow ventilation under homes can be negatively impacted and the usual humidity released from the ground therefore cannot escape the subfloor space. Moisture is constantly released into the atmosphere from the earth and is dispersed by the wind. However, when a house is built over the earth without adequate ventilation, there is nowhere for the moisture to go but into the building materials.
