Koala Insulation Guide to Understanding R-Values in Insulation

When choosing the proper insulation for your home or business, understanding R-values is essential. R-value is a measure of insulation's ability to resist heat flow. The higher the R-value, the more effectively the insulation reduces heat transfer. At Koala Insulation of St. Paul, we understand the importance of R-values in choosing the right insulation for your needs. In this guide, we'll explain R-values, how they're calculated, and how to choose the right R-value for your insulation.

What are R-Values?

R-values measure an insulation material's ability to resist heat transfer. The higher the R-value, the better the insulation reduces heat flow. R-values are measured in units of thermal resistance, or "R," the temperature difference ratio across the material to the heat flow through the material. For example, an R-value of 20 means that the insulation material reduces heat flow by a factor of 20.

How are R-Values Calculated?

R-values are calculated based on the thickness and thermal conductivity of the insulation material. Thermal conductivity is a measure of how well a material conducts heat. The lower the thermal conductivity, the higher the R-value. R-values are also affected by factors such as air leakage, moisture content, and temperature.

How to Choose the Right R-Value for Your Insulation

The right R-value for your insulation depends on several factors, including the climate in your area, the type of heating and cooling system you have, and the insulation's location in your home or business. In general, colder climates require higher R-values than warmer climates. Additionally, areas of your home or business exposed to more heat or cold, such as attics or basements, require higher R-values than areas that are more protected, such as walls.
