Why You Cannot Do Without Sub Floor Ventilation
Reasons Why Every Home Should Have Sub Floor Ventilation
Subfloor ventilation offers air flow in places where it is common to find mold, mildew, rotting wood and pests, usually in the subfloors of most houses and buildings. If left untreated, such conditions can lead to health complications.
How It Works
The whole point of a subfloor ventilation system is to replace the moist stale air with fresh dry air. The most basic form of this type of ventilation involves placing air ducts in strategic places around the building. After installation, natural ventilation is meant to take care of the rest. As stated, this is the most basic form, but in most cases it is not sufficient.
Simply having air ducts allowing air into and out of the subfloor is not enough, and you need the help of fans that help speed the process along. These fans will aid in expelling the moist stale air and replacing it with clean air from outside the building. Other forms of subfloor ventilation involve placing fans on one side of the building to draw in fresh air, then exhaust fans on the opposite side which are meant to expel the moist air. Some of these ventilations can be modified to not only extract moist air from the subfloor, but from other parts of the building that tend to be over moist.
It is important to note that subfloor ventilation only works well if you have avenues for replacement air.
Why You Need It
Below are a few reasons why subfloor ventilation is important:
1. Inhibits the growth of mold. Mold thrives in moist conditions, and one of the best places is your building’s subfloor. If its growth is left unchecked, mold can lead to a number of health problems mostly respiratory conditions. Symptoms that mold causes include coughing, sneezing, asthma attacks, congestion, wheezing, and allergic reactions. The proper circulation of clean air will help in eliminating the mold.
2. Termite protection. Termites enjoy wood, and more so, are attracted to moist areas, such as a subfloor lacking proper ventilation. If the wooden structures have already started decaying as a result of the increased moisture, then the termites will only worsen the condition. They will eat into the wood, causing it to become weak.
3. Moist conditions in the subfloor can pose a risk to the building’s structure. This is because moisture can increase the rotting of the wood. This weakens the timber, which in turn weakens the entire structure. You can prevent this from happening by installing subfloor ventilation.
4. Reduction in potential costs. If you think about the damage that moist conditions can cause, then you will realize that repairing them will cost quite some money. This will cater for the medical costs as a result of the respiratory issues caused by the mold as well as the repairs to the building’s structure as a result of decay and termite infestation. All this can be prevented by simply installing a proper subfloor ventilation system.
