Mould on the other hand produces substances

Ventilation of the home through the floor is done by having vents and grilles so fresh air can be let in and out through the ground. Sometimes though, this is not adequate.

Sub floor ventilation is a system of pumps, vents and fans that draw in air from the outside, eliminate the stale and circulate the one beneath. The system also draws out excessive moisture from the air. This part of the house is particularly susceptible to high humidity because of howclose it is to the ground. Wet earth and rainwater can evaporate and find their way into the room through the floor.

Basically, the fans will create a vacuum when they propel the air, so the drier, cleaner air from outside will rush in. Fan forced systems heat the air. Inline fans are placed along the vents, and these force the air to move where it cannot do so on its own. The pumps move the air to and fro, while the vents are the channel for the air. This system with all its components qualifies to be a fully operational HVAC System. (Heating, Ventilation and Air Conditioning)

Sometimes vents are actually present but they could be blocked. In that case, they have to be cleared. For them to be most effective, fans have to be added. A good system will work quietly but efficiently. It will also be made out of material that does not rust.

The risks of not having this type of ventilation are:

• Mold multiplying-when the damp air condenses, the moisture create a conducive environment for blow mould. Mould on the other hand produces substances that trigger allergic reactions and affect the nervous system. • Rot-timber floors especially can be destroyed when mold grows on them. Apart from being unsightly, they are very hard to eliminate. Replacement costs have to be borne in that case. • Termite infestation- the humid air attracts termites which bore holes into wood and causes them to collapse. • Unpleasant odor.

When mold is present in large numbers, the home develops a musty smell that always hangs in the air. This creates a very uncomfortable environment for both the occupants and guests.

The system can be used in conjunction with the heat recovery ventilation system where the layout of the floor is accommodative. They can also be installed independently. The benefit of having this kind of system in the home is that it saves you heating and cooling costs in the cold and warm season respectively.

Much as it works beneath the floor, the room above also gets to be ventilated. There are diffusers that distribute the clean air and get rid of the spent one.

Before you do it, your home will be assessed, measurements taken, and a little reconstruction may have to be done to accommodate the new structure. From then on, you can live in a clean comfortable and healthy home.So save yourself the nightmare of having to replace entire floors by getting floor ventilation system. Only in doing so, make sure you go for the best dealer. Be wise and perform checks on the kind of material and installation method that will be used.
