Understand and Control the Flow of Household Moisture to Prevent Dampness

in Moisture

If moisture manages to creep its way into a house it can create many problems with the damp that it causes. Top of that list are damage to property (even structural in some cases), allergies, mould, bad odours, loss of energy efficiency.

If you want to steer clear of such problems and improve your humidity, air quality and stifle the effects of damp and increase your households energy efficiency then here are a few tips for you to mull over. One of the most important things is moisture control. If you want to prevent the negative consequences of damp caused by moisture and increase your houses energy efficiency then you need to first effectively control the moisture level in your house.

To improve the flow of water moisture around your household the following three things need to be concentrated on.

1) Attics
2) Foundations/Basements
3) Walls

In order to effectively control moisture flow through a home you need to understand the basics of how it moves. The three ways that moisture travels through a home most typically are: 1) By heat transfer 2) By diffusion 3) Via air currents.

By far the most important way moisture travels is through water vapor in wall cavities via diffusion. The air due to simple physics will of course always move from an area of high concentration (outside) to an area of low concentration (inside) through any gap. Transfer of moisture via air flow currents is by far the quickest method, usually cracks and holes in walls are the number one reason for this occurring and these should be effectively filled in.

The other way of diffusion, through materials and heat transfer takes a lot longer and the uasual household building materials are already very good at preventing this from happening, along with insulation which helps in the decreasing of heat transfer.

It will also be helpful to fully understand exactly how moisture appears in a household. Firstly water is usually carried in the air, the hotter the air the more water it is capable of carrying. If the air temperature keeps reducing it sooner or later it will hit a level where it is not able to carry the water anymore. This is known as the dew point and is when the moisture will immediately condensate on the nearest cold surface and start causing problems.

So by having decent vapor diffusion retarders fitted, filling in all cracks and holes and keeping a good flow of air are the easiest and most effective ways to control the spread of moisture and damp. If you are still having trouble with moisture then seriously consider the use of a home dehumidifier (ebac dehumidifiers come highly recommended) they are very effective at extracting moisture from the air even in very damp conditions. If you follow the above guidelines then you ought to be able to effectively handle most damp and moisture problems either with or without a home dehumidifier
