Why You Need The Right Sub Floor Ventilation

Copyright (c) 2016 Matt Reardon

A safe and healthy home and work environment is a must if you are to be in good health. You should be able to breathe in clean fresh air as you go about your activities in the building. A musty and damp room can cause you to develop allergies and respiratory infections whereby you end up coughing and wheezing. You can however stay in a healthy home by ensuring that it is well ventilated. You should also ensure that you have sufficient sub floor ventilation in your home in order to have a safe environment to live in.

How Sub Floor Ventilation Works

If you have a sub floor that is damp, has mold and a stale smell then you definitely need some form of sub floor ventilation. Ventilation gets rid of the damp air and replaces it with dry fresh air. The simplest form of ventilation is natural ventilation where vents are set up on the walls of the building. This allows fresh air to move into the rooms and the basement.

If natural ventilation does not work well enough, you can install fans in the sub floor. The fans will get rid of the damp air and will replace it with fresh air from outside. The fans should be placed strategically to ensure that fresh air comes in from one side and the damp air is expelled from the other side. If fresh air comes in from opposite sides, there is a risk of the damp stale air rising into the building thus causing a health hazard.

What Causes Dampness?

Dampness occurs when moisture accumulates inside a building and does not have a way of getting out into the open. The moisture gets trapped in the building due to poor ventilation. An accumulation of moisture results in the growth of mould which can easily spread in the sub floor. The mould then gives rise to fungal spores which become airborne.

The fungal spores are a health hazard when inhaled because they are known to affect the respiratory system. You can end up developing respiratory conditions such as asthma, bronchitis and you may also experience chest pains.

Planning For Sub Floor Ventilation

It is always better to plan for sub floor ventilation during the design of your house. This will ensure that you do not have to modify your house later on in order to accommodate ventilation. The ventilation rate of your sub floor should therefore be established so that you can get the ventilators that will give your under floor sufficient air flow.

When planning your landscaping, you should ensure that the vents that are meant for ventilating the under floor are not obstructed. You should also consider the positioning of the vents if you want to build in an area that is prone to flooding during the rainy season. The vents should be raised to avoid water getting in and increasing the risk of dampness.

Benefits Of Sub Floor Ventilation

Once you have the right sub floor ventilation in place, you will keep your home free from condensation, mildew, mould and dampness. Your home will also be free from bad odors and from termites which can cause great damage to the structure of your home.
