    The secret in sub-floor ventilation troubleshooting and design

    Envirofan

    The secret in sub-floor ventilation troubleshooting is not so much a secret, as it is what to look for when sub-floor ventilation problems are present.

    Sub-floor ventilation problems can be detected when looking at the status of the visual sub-floor vents or the lack of them.

    If additional passive vents are going to be installed that does not mean that this will fix sub-floor ventilation problems but certainly more aeration to the sub floor region is a positive step.

    Caution should be exercised in not being over zealous in removing a lot of bricks around the home in the sub-floor region as it is prudent to take the time to get the sub-floor ventilation solution right the first time, as the work that you have done may have to be reversed to make it right.

    Experience has told Envirofan that the effective way in getting the right mix in sub-floor ventilation is to combine the use of passive vents with fan-forced sub-floor ventilation systems.

    Consider this point. If a sub-floor ventilation system is drawing the humidity (damp air) out, air flow will travel from the point of least resistance. So if a passive is in close proximity to a fan-forced sub-floor ventilation system supply air would be drawn through the passive vent and out through the fan-forced sub-floor ventilation system. Sub-floor ventilation systems placement is important that is why it is important to get professional advice from reputable people.

    Another obvious sign of poor sub-floor ventilation is a distinct musty smell inside the dwelling.

    No doubt you are familiar with the expression the writing is on the wall if mould is present on the walls and ceilings this is indicator that poor sub-floor ventilation is present.

    When a sub-floor is inspected and it is apparent that the ground is discoloured (by wetness) from other parts and the presence of mycelia (fungi), this is a visual sign that moisture is finding its way into the sub-floor area. This does not indicate poor sub-floor ventilation, however it does prove that moisture is present.

    What can be done to remedy this problem? One can remedy the moisture flow and rectify its source by subsoil drainage. If the source cannot be determined then bolstering sub-floor ventilation would be advantageous, as it would not allow the humidity from this source to accumulate in the sub-floor area. If nothing is done this may encourage termites.

    If the sub-floor ventilation is increased substantially this should shrink the fungi as usually it thrives in moist humid conditions.
