What Is a Good R-value for Insulation?

A worker is spraying blown fiberglass insulation between attic trusses at a residential construction site. The completed application will be 22” deep providing an insulation value of R-60.

When it comes to choosing the right insulation company for your insulation needs, you should feel confident that they know what they are knowledgeable about the matter at hand. This is especially true when it comes to any conversation regarding the R-value of a particular insulation product.

But we should probably back up a step. First, let’s take a look at what R-value actually means and why it is important when selecting insulation products. Fully equipped with the right knowledge about the various insulation companies and products available, we can then discuss the importance of choosing the right business to meet your needs.

What is the R-value of Insulation?

The R-value of insulation is a measure of the material’s ability to absorb and redirect thermal energy. The higher the R-value, the better able the material to withstand high temperatures by absorbing radiant energy in the environment. Insulation companies use this knowledge to make decisions about the R-value of your home.

Why is the R-value of Insulation important?

Understanding what the R-value of an insulating material actually means is the first step in understanding why it is important. That is because you can then begin to see how choosing a “good” R-value is no simple matter. It isn’t like the measure is equivalent to a scale of quality, longevity or price. Instead, it is simply one of many factors that must be taken into consideration for whatever specific insulation project is in question. We explain further below.


How Does Choosing the Right Company Make a Difference?

Choosing the right insulation company can make a huge difference in the quality of your insulation experience. They will be the ones you turn to for advice and information about insulation, and whether or not they provide useful, accurate and helpful guidance is a critical consideration. This is because the R-value of your insulation is not always set in stone.

You see, depending on the various factors involved, you may require a higher or lower R-value. Take, for instance, an attic insulation project on a house in Anchorage, Alaska. The temperatures in that part of the world fluctuate greatly and regularly, but they are generally on the cooler side. This means a higher R-value insulation—meaning one that can retain more heat for a longer period—is a worthwhile and smart investment.

It seems straightforward, right? Well, let’s take a look at an example on the other end of the spectrum. Say, for instance, insulating a home in Mexico City, Mexico. For being so near the equator, we can reasonably suspect that there may be temperature fluctuations regularly in this city. However, they will tend to be higher temperatures than in Anchorage. As a result, a lower R-value insulation would be more suitable so that it still manages some of the heat but doesn’t block it from escaping.

Using these two examples makes it plain to see how different R-values can have different applications and uses. Therefore, as previously stated, one of the most important things that you can do for your insulation project is choosing the right company to perform the work. You want to ensure that they have your best interests in mind and can perform the work to a quality standard with the right material.
