When choosing the best insulation for your home, Know your “R” s

A poorly or partially-insulated home can make your home a frigid icebox during the winter and make it very uncomfortable from the heat in the summer, with even more unpleasant energy bills to to go along with it. With proper insulation, you won’t just have better temperatures inside, you’ll save some money on those high energy bills.

There are many insulation products out there on the market. The insulation’s R-value, or resistance to heat flow, is the key to comfort and energy savings in your home.

The desired R-value varies in different parts of the home and depending on which region of the USA you live in. The homeowners and contractors need to pick the appropriate insulation for their homes being built or updated.

What are R-values?
In construction, the R-value is the measurement of a material’s capacity to resist heat flow from one side to the other. In simple terms, R-values measure the effectiveness of insulation and a higher number represents more effective insulation. R-values are additive.  For instance if you have a material with an R-value of 12 attached to another material with an R-value of 3, then both materials combined have an R-value of 15.
