Insulation R Value


A well insulated home will be much easier and a lot less costly to heat and cool. There are all sorts of different types of insulation that you can choose from these days. One thing that should be a major factor in your decision of which insulation material to use is the insulation R value.

The insulation R value is a measurement of how well the insulation keeps hot air from moving from one side of the insulation to the other, meaning how well it will keep your home warm in the winter and cool in the summer.  The insulation material is creating a thermal barrier to keep you home comfortable.  The types of insulation products available include foam board, spray foam, fiberglass, and cellulose.  The higher the insulation R value the better the insulating properties of the material.

This is important when you are installing insulation, whether you are putting in attic insulation, wall insulation or basement insulation. Foam insulation, especially spray foam insulation, tends to have a relatively high insulation R value, which has made it a popular choice when this type of material is suitable. However, some people prefer the ease and relatively low cost of using blown in insulation for places like the attic.

Some types of insulation definitely work better in some places than others, so it is important to look into other characteristics of your insulation as well as the r-value. Keep in mind that you can use a thicker layer of an insulation with a lower r-value in order to get the same effect, so it might be cheaper to do this if the space is available and the less expensive type of insulation material is suitable for the location.

Another factor you will probably want to consider is the ease of installation. Some people like to do as much work as possible themselves, and others would rather hire professionals to do the work. Those who are do-it-yourself types tend to like rolls and batts since these are pretty easy to install on your own without a lot of mess. They are great to use for unfinished rooms.

As you can see, there are a number of things you should consider when choosing your insulation material, including the insulation R value. All other things being equal, you should choose the insulation with the highest r-value.
