A Guide to R-Values for Insulation

Details

When choosing home insulation, you will likely see the term "R-value" on the products you encounter. The R-value rating system measures and grades an insulation's resistance to heat flow. Here is what you need to know about this grading scale and how to use it for the benefit of your home, comfort, and budget.

What Is R-Value?

R-value lets you know how well an insulating product can prevent heat from entering or leaving your home. The exact value varies depending on the type of home insulation, but generally, the higher the R-value, the greater the heat resistance and the better insulation the product provides.

What R-Value Do You Need?

You don't always need to choose the insulation with the highest R-value. Those products rated on the higher end of the scale are designed for the coldest climates, as they offer the most protection from temperature extremes. 

The Department of Energy has assigned a number from one to seven to different areas of the country; these areas are called climate zones. Most of Indiana and Michigan sit in climate zone five. In this area, attics should be insulated with R-values between R49 and R60, walls between R13 and R21, and floors and crawlspaces between R25 and R30.

What Are the Benefits of the R-Value System?

The system gives you greater insight into the heat flow resistance of different kinds of insulation so that you can choose the right product for the needs of the home. For area homeowners, selecting a material within the recommended range for climate five will ensure dependable levels of protection against temperature extremes. Your home will be warmer in winter and cooler in summer, making the household more comfortable and temperate while reducing the usage of heating and cooling systems. As a result, you can save money on your energy bills and lighten the home's carbon footprint.
