What is the R-Value of Insulation?

If you need to install home insulation, you need to take several factors into consideration before even choosing the right type of insulation for your project. One of these factors factors is the R-value. Wondering, “What is R-value?” Read on to find out more about the R-value of insulation!

R-value is indicative of insulation’s resistance (R) to heat traveling through the given thickness of the material. The higher the R-value is, the better the thermal performance of the insulation—and the greater the effectiveness of the insulation.

R-Value of Insulation: A Closer Look

Calculating R-value is dependent on a few things: the type of insulation (including the insulation’s material, thickness, and density) and how much of the insulation is installed. When taking into consideration a multi-layered insulation installment, the R-values of each individual layer of insulation are added together.

In addition to the R-value of insulation, it is essential to properly install your home’s insulation to achieve the maximum R-value. Improperly installed insulation can completely undermine your energy efficiency efforts! When insulation is compressed, bent, squished, or otherwise distorted, the full R-value will not be provided.

Factors That Affect the R-Value of Insulation

Not sure how much insulation (or R-value) you will need? It varies for each household and climate. Depending on your area’s average climate, the type of heating and cooling system you have, and what area of your home needs to be insulated, you will see varying results for the amount of insulation you will need to achieve an effective R-value.

If you live in a colder climate, you’ll need insulation with a higher R-value, whereas if you live in a warmer climate, you will need less insulation—and a lower R-value—to maintain good energy efficiency and comfort levels in your home. Oftentimes, the physical structure of your home will also help you determine how much insulation (or R-value) you will need to properly insulate your home. Homes that were built more than 10 years ago and homes with basements, attics, or crawlspaces typically require more insulation than others.

Need Insulation Contractors in Upstate New York?

You should talk to a local insulation company to get the most accurate estimate of the right amount of insulation for your home. Working with an insulation expert is doubly important since the effectiveness of insulation’s resistance to heat flow depends on how the insulation is installed, and where in your home the insulation is installed.

Typically, the insulation contractor will walk through your home with you to determine where and how the insulation should be installed and then give you an estimate for the work.
