Okay we couldn’t help using ewe in the title. But how can you write about wool insulation and not use it?

Every insulation has benefits that make us love it, so making the choice will have to depend on what your needs are. So for the third in our series on insulation we are going to be highlighting wool insulation.

Wool insulation brings to your home the same ability to adapt to the environment that sheep have. Living in hot, cold and wet environments and still be protected is a major advantage inherit in wool. As a building insulator wool can retain these properties to create and maintain a healthy, safe, and environmentally responsible haven in your home.

Another advantage to wool is it’s ability to absorb and release moisture. So in wet and cold conditions removes the water and in doing so actually release heat. If the air is saturated with water vapor wool can absorb up to 40% of its dry weight and produce 960 kilojoules of heat energy kilogram of wool. This warmth will not be felt inside the building but this acts to prevent condensation in cavities by keeping the tempature above the dew point.

In warm conditions this insulation will actually release moisture into the air helping to slow and cool the flow of heat into the home. This has a major impact on the internal temperature of a building.

Wool insulation has also been shown to absorb and breakdown the harmful chemical formaldehyde. Formaldehyde has been classified as a carcinogenic, cancer causing agent, and many building products emit this throughout the home. Products such as timber, glass, glues, and even upholstery has been shown to release this dangerous chemical

Wool has been long know to break down formaldehyde into safe molecules. This ability is also inherent in Sheep Wool Insulation, this reducing the formaldehyde threat to building occupants. The Central Testing Facility in Tokyo, Japan found that when formaldehyde was released into a chamber wool insulation was able to absorb 96% of it within seven hours. Imagine that working within your home making your interior environment free of harmful chemicals.

It’s durability is another plus as it is able to adjust to fit. So an air tight fit will be achieved as it fills in cracks and crevices. It also has a life expectancy of over 50 years. Wool also has a higher fire resistance than cellulose/cellular plastic insulations, it melts rather then burns. It melts away from the source of ignition source and extinguishes itself, making it extremely fire safe.

Last but not least, is the fact that it takes less energy to manufacture wool insulation then glass fiber insulation.
So wool making your list of to look at for insulating your home is a definite must. Each type of insulation we highlight all have something we love about them but for open …

If you are thinking of going off-grid or even just trying to cut your current energy cost then an important key is insulation.

You can change all your appliance to energy star, replace old drafty windows, change lighting to fluorescence, unplug what is not in use and still be using way more energy then needed if you have little or no insulation. Insulation should also not be something you only think about for your roofs and walls. Insulating pipes, duct work and water heaters also make a dent in your energy consumption.

Today we are lucky enough to have many options for insulation that is not only good for the environment, works on par or better then synthetics/man-made products, but has long life and cost close to conventional methods. Some of the choices we will be highlighting are cellulose, wool, straw, and cotton.

All of these organic and environmentally friendly types of insulation have benefits that make them truly lovable. So choosing the right one comes down to what your individual needs are. Cellulose can be blown into enclosed walls, wool can breakdown and absorb formaldehyde, cotton is made from recyclable jeans, and straw in a bountiful organic product.

Just how much insulation you need can be found through the Department of Energy insulation program. This website will help you determine what R value you really need to insulate the different areas of your home. As each environment has different needs so does each area of your home. To the left a picture of where insulation is needed to make your home comfortable and energy efficient. Since homes that are older tend to not have insulation in walls and floors these spaces will usually need a blown in type since opening a wall to add insulation is to expensive if you’re not planning on major renovating.…

Since we talked about going energy efficient, we thought we tell you about energy calculators. Energy calculators can give from a rough estimate to a detailed one of your energy consumption and costs to run your home.

We have found several free on the internet and would like to share them with you. If you want a in depth one go to Home Energy Saver , this one may take a while so you can come back just save your session id#. For a quick estimate we found one from East Central Energy, also Santee Electric Cooperative has one with a little more input necessary. When doing our search we found that most government sites send you to the Home Energy Saver, and power companies use the East Central Energy version.

So take the time to do at least the quick one, then make some adjustments and you can see how that can either save or cost you in your energy costs. When your hooked or if your ready to have a more in depth one move to the Home Energy Saver.

Good luck and good savings. We’ll all be living off-grid sooner then we thought if we all take one small step at a time.…
