What is the Best R-Value for Insulation?

Finding the right insulation for your home can be confusing, and you may have several questions. What is R-value? How much of an impact does it have on my home’s overall energy efficiency? How do I get the most out of my insulation while also staying on budget? These are all valuable and important questions to ask, and thankfully, the answers to these questions make finding the right insulating product much easier than you might think.

Insulation levels are determined by their R-value, which is a measure of the material’s ability to resist heat transfer. Higher R-values are equated to insulating materials that have better thermal performance, which is why higher R-values are recommended for parts of the country that experience cold, frigid winters. Inversely, lower R-value means less thermal performance. Lower R-values are recommended for southern parts of the country that experience warmer temperatures year-round and only mild winters. So, determining the best R-value for your home really depends on where you live.

For example, someone living in San Antonio, Texas, may only need insulation with an R-value of around R35 for an uninsulated attic. Another person living in Boston, Massachusetts, however, will likely need an R-Value closer to R55 or even R60 for an uninsulated attic. Energy Star® offers a chart that makes it easy for homeowners to decide what R-Value will work best for them in terms of performance for their local climate. And, since higher R-values mean a higher price, it allows homeowners to find the right balance for their budget as well.

Here at Beldon®, we proudly install Owens Corning AttiCat blown-in fiberglass insulation that does not compress – or settle – over time, and maintains its R-Value for years to come. We can help you find the perfect R-Value for your home and can install the lightweight, expanding fiberglass material in a way that best insulates your place of residence.
