The longevity of the subfloor structure can be increased preserved by effective sub floor ventilation. The toll that uncontrolled damp can take on timber structures can be significant. When subject to this kind of damp, this enlarges the timbers cell, expanding the timber itself. This creates flexibility in the timber which can cause bouncing in floor structures. Damp can cause timbers to increase in volume, thereby pushing itself on internal or external wall structures and causing cracking. If the cracking persists, these walls may need to be rebuilt.

Attraction to termites

Sub floor damp which is not controlled can expose the home to termite attack. This is obvious as termites are attracted to moisture and the food source they thrive on in these moist conditions. Effective sub floor ventilation will address this situation.

Most materials used in the construction of building are porous. When humidity (internal damp) is above acceptable levels this allow a bacterial spore to get a foothold into these crevices and propagate. Where the infection has reach overwhelming proportion, this will release more spores into the air, contaminating it. Where there are people occupying this dwelling, this can have a profound effect on their health as they are ingesting these spores into their respiratory tract. This can ultimately make them quite sick.

Headaches, nauseating, breathing difficulties, eyes, nose and throat irritations are likely. Internal humidity may be added to by poor underfloor ventilation. At what cost will effective sub floor ventilation be administered.
