With the abundance of insulation products on the market today, choosing the most energy efficient insulation for your attic can seem overwhelming. Although it’s best to get professional advice before you make a choice, it’s good to understand the various qualities of insulation and how they affect energy efficiency.
Insulation’s purpose is to slow the movement or flow of heat energy. An insulation product’s effectiveness at resisting heat flow is called R-value, and this value varies depending on the type of insulation and the material it’s made from. Installing the right total R-value matters too, and in our climate region, the recommended amount for attics is R-49 to R-60. R-value is cumulative, as well, so if you have some insulation already in place, your installer can calculate its R-value and then add new insulation to reach the optimal level.
While the total R-value matters a lot, the type of insulation you choose can ultimately determine how much improvement in efficiency you gain. Here are three of the most common types of insulation used in attics, and how they perform:
