R15 vs R13 Insulation: Which One Should You Choose?


When it comes to insulating your home, there are many factors to consider. One of the most important decisions you’ll make is choosing the right type of insulation. Two of the most common types are R15 and R13 insulation. In this blog post, we’ll explore the differences between the two and help you decide which one is right for your home.

R15 Insulation

R15 insulation is a type of fiberglass insulation that has a higher R-value than R13 insulation. The R-value measures the insulation’s ability to resist heat flow. The higher the R-value, the more effective the insulation is at keeping your home warm in the winter and cool in the summer. r15 vs r13 insulation is typically used in areas with colder climates, where the winters are harsher and the need for insulation is greater. It’s also a good choice for homes with larger attics or walls that require thicker insulation.

R13 Insulation

R13 insulation is another type of fiberglass insulation, but it has a lower R-value than R15 insulation. It’s typically used in areas with milder climates, where the winters aren’t as harsh and the need for insulation isn’t as great. R13 insulation is also a good choice for homes with smaller attics or walls that don’t require as much insulation. It’s more affordable than R15 insulation, making it a popular choice for homeowners on a budget.

Which One Should You Choose?

The decision between R15 and R13 insulation ultimately comes down to your specific needs and budget. If you live in a colder climate or have a larger attic or wall space, R15 insulation is the better choice. It will provide you with better insulation and help you save money on your energy bills in the long run. However, if you live in a milder climate or have a smaller space to insulate, R13 insulation is a more affordable option that will still provide you with adequate insulation.


Choosing the right insulation for your home is an important decision that shouldn’t be taken lightly. R15 and R13 insulation are both effective types of insulation, but they have different R-values and are better suited for different climates and spaces. By understanding the differences between the two, you’ll be able to make an informed decision and choose the insulation that’s right for your home and budget.
