Introduction


An extensive number of buildings in Australia have suspended flooring with an easy-to-access subfloor area, which is usually damp, confined, and inadequately ventilated. Such a space creates an unhealthy environment that impacts the health of humans as well as property. Thus, it is indispensable to have an appropriate subfloor ventilation system in place for this purpose, enhancing the overall quality of living. 

These systems are also effective in fighting against the problems of pests, mould, and mildew that often reside as a result of abysmally ventilated spaces. So, let’s dig deeper into the working of a subfloor ventilation system!

 

The Working 


The subfloor ventilation system works by getting rid of the suspended damp air from your enclosed area and replacing it with warm drier air. The easiest way to do so is by installing multiple vents in the subfloor area that provide natural ventilation. Nevertheless, there could be situations where natural ventilation may not be adequate. In such cases, it is recommended to install subfloor fans along with vents for proper air circulation. These fans draw in the fresh air from outside, circulate it in the area, and push the moist air back out. 


It is imperative to note that cross ventilation works only whenever the air enters from one side of the building and is thrown out by fans from the other side. Cross ventilation may not be adequate in case some pockets hinder the free passage of air. In such a situation, the ventilation can be done by ducting the fans to one or more points for extracting the damp air from the subfloor area.  


While setting up the subfloor ventilation system, it is essential to keep the following points in mind:


  • Carefully select the appropriate areas for installing the fans.
  • To get rid of the moist air, easy availability of replacement air is crucial, and that can be achieved via strategically positioning the vents to allow the air to enter the enclosed subfloor area.


Advantages of Subfloor Ventilation Systems

 

  • Protection against Termites

 

It has been observed that a moist environment creates ideal conditions for termites to thrive. The chances of termite infestation increases in places where timber has become damp and begun to decay. Proper subfloor ventilation can come to your rescue in such cases as it lowers the chances of termite infestation to a large extent.

 

  • Confined Growth of Mould


Moulds prefer damp or wet surfaces. If you see mould growth in your subfloor space, it certainly is a reason to worry. Mould triggers several health problems, including respiratory disorders that can be mistaken for allergies. Adequate subfloor ventilation cuts down the moisture in the air that helps limit the mould growth.


  • Fewer Chances of Cosmetic & Structural Damages

 

A damp subfloor area often leads to structural and cosmetic damages. The dampness in the air can cause healthy timber to start decaying and further invite termites. Proper ventilation is a must to ensure that the timber, which is the foundation of any building, remains healthy and dry without any decay or rot.


  • Prevention against Health Issues


With exiguous ventilation, radon gas that otherwise cannot be seen or smelt may be present in your home at dangerous levels. A high concentration of this gas can be quite harmful to you. Allergens can also accumulate over a period of time in poorly ventilated spaces, thus giving you all kinds of allergies. A subfloor ventilation system can help avoid these health concerns, along with many others.


  • Cost Advantage


We cannot put a price tag on the cost of good health. Dampened subfloor areas infested by termites, rot, or mould can result in many health issues. The expenses incurred for treating a termite attack and potential structural damages can be quite high. Many times, even the insurance would not provide coverage for damage caused by termites. In comparison, the expenditure involved in setting up a subfloor ventilation system is lesser. 

Why You Require a Subfloor Ventilation System?

It is easy to overlook the fact that the area under your home requires proper ventilation. All things considered, you are not down there to check on the quality of air. However, it does not imply that it’s not essential. In case there is no proper aeration in your subfloor space, it can have a significant impact on your overall living environment and health. 

Damp areas make way for rotten timbers and mould growth. Even worse, infected wood can also be a home for termites. In the worst situations, moisture from under the building can cause many illnesses. Thus, it is essential for you to keep yourself and your loved ones healthy by averting dampness in your enclosed subfloor space. And to do so, a proper subfloor ventilation system is required.
