What is Insulation R-value?

If you’re considering ways to increase the energy efficiency and performance of your home, insulation should certainly be on your list of potential solutions. There are plenty of things to consider as you research insulation and perhaps the biggest factor is R-value.

Simply put, the R in “R-value” indicates resistance. This is used as the basic measurement of the heat resistance of the insulation material and is calculated per inch of width.


How is R-Value Calculated?

To explain this, let’s start with an example. Solid wood has an R-value of 1. R-value is calculated per inch of width. Therefore, a three-inch-thick board has an R-value of 3. Blown fiberglass installed in an attic has an R-value of 2.2 per inch, so 12 inches would give you an R-value of 26.4 in your attic insulation project.


How Much Insulation is Needed?

There are a variety of factors that can affect the specific amount of insulation you will need for your home, including:

  • Regional location
  • Type of heating and cooling system you have in your home
  • Size and age of your home
  • Areas of your home that need insulation

The most influential factor in how much insulation you will need will be your regional location. Consulting with an experienced professional, such as the experts at Valley Insulation, can help you determine exactly what type, and how much insulation will work best for your needs.
