All You Need to Know About R-Value for Attic Insulation

Contents

Poor attic insulation is one of the many reasons why households on average deal with high energy expenses every year. In fact, more than 90% of homes in the U.S. are under-insulated. Having a well-insulated attic allows you to control an even temperature throughout your home. With this, you can save on your monthly energy bills and even prevent major issues, such as ice dams.

R-Value for Attic Insulation

One of the important aspects of attic insulation you need to know involves understanding its R-value.

How Does Attic Insulation Work?

Heat can be transferred in three ways: conduction, convection and radiation. While your home’s existing insulation makes sure to slow down the heat flow, heat can still spread from warmer to cooler points in your house until the temperature is the same everywhere. This includes your attic space. Without proper attic insulation, you can’t keep the heat within your living spaces during winter. In the summer months, heat comes into your house from the outside and spreads, making your cooling system work harder than usual to remove the heat from your home.

What Does R-Value Mean?

To keep the indoor temperature at a comfortable level year-round, consider your home’s R-value. The higher the R-value, the greater the insulating power and resistance to heat flow. R-value recommendations for exterior walls are typically R-13 to R-23 while R-30, R-38 and R-49 are common for attic spaces and ceilings. Depending on where you live and the climate of your area, you may need different R-values. If you live in a warmer climate, for example, you need lower R-values than those in colder climates.
