How Subfloor Ventilation Can Prevent Termite Infestation
Ever gone through drastic measures just to get rid of a termite infestation only to find out that a handful survived and are likely to make the situation worse? Did you know that termites thrive in damp dark places? You may be thinking that you don’t have such areas in your home, but what about your subfloor? Your subfloor could be the source of all your woes because it is dark, and damp, especially if you do not have a form of ventilation to aerate the place. So instead of dealing with getting rid of them, you should deal with ensuring that there is no warm, dark and moist place for them to form a habitat.
How Subfloor Ventilation Works
Subfloor ventilation involves supplying clean air to the subfloor while sucking out stale moist air. A poor version of this type of ventilation will involve placing fans around the building which will direct air into the subfloor. However, with no exhaust, the stale moist air will have nowhere to go. A better ventilation system will draw out stale moist air, which in turn will create negative pressure inside the subfloor thus allowing fresh air to be drawn in. Most ventilation systems use fans, insulated ducting and humidifiers. You can easily find subfloor ventilation systems that are not only efficient but cost effective too.
Different Types Of Subfloor Ventilation
Now that you know how ventilate your subfloor, it would be to your advantage to know the different types that are available on the market.
- Air vents ventilation. This is the simplest form of ventilation and is made out of bricks. It involves creating vents which are positioned in various parts of the subfloor. The placement allows for damp air to flow out from one side, and clean air to flow in from the other. For this type of ventilation to function properly, it is important that these vents stay clear or any blockage such as dirt or debris.
- Forced ducted ventilation. This type of ventilation is suitable if your main concern is proofing your house against pests and decay. This type of installation does not involve making any changes to your house. It focuses more on creating more flow of air to areas that are prone to be stale and moist. This system achieves this through the use of special ducting and fans which help in drawing out stale air while drawing in fresh clean air.
- Powered fan ventilation. This is the most popular form of subfloor ventilation. It works by creating negative air pressure through the fans. The stale air is then drawn out through strategically positioned vents, which also allow in dry replacement air. Most of these types of systems are constant or timed, with the latter being more energy efficient and cost effective. The timed versions means that the system will only operate during warm and dry weather, to ensure that the humidity inside your house remains balanced.
