Blown In Insulation vs. Rolled Insulation: Which One Is Better?

February 1, 2017 12:30 am Published by Leave your thoughts

Deciding on what type of insulation to use in your home is never an easy job, especially if you are not familiar with the different advantages and characteristics of each type. Cost, efficiency, ease of installation and quality are all points to consider.

Two of the most common types of insulation are blown in insulation and rolled insulation. At Interstate Insulation, we offer both rolled and blown in insulation in Fargo, ND. Blown in insulation is a loose-fill insulation typically made of recycled materials. Rolled insulation is what people traditionally think of when they think of insulation—flexible sheets of insulation made of fiberglass or rock wool. So which type of insulation is better? Let’s compare.


R-value refers to a rating system used to measure the thermal resistance of insulation. The higher the R-value, the higher the efficiency. The R-values for rolled insulation and blown in insulation are nearly equal. The R-value for rolled insulation ranges from about 3.1 to 3.4. The R-value for blown in insulation is about 3.2 to 3.7. The R-value will vary depending on the specific materials your brand of insulation is made of and the area of your home being insulated.


There are several variables that can impact the final cost of an insulation installation: the type of insulation, the quality (R-value), the square footage needed to insulate the area and the part of the home to be insulated. However, when you are simply looking at the cost per square foot of similar quality brands, blown in insulation is slightly more expensive than rolled insulation.


There are installation pros and cons for each type of insulation as well. Rolled insulation is easier to install in some respects because you can simply roll it out, cut it to fit your space, and then lay it down. However, rolled insulation can be difficult to install in hard-to-reach places. Blown in insulation, on the other hand, is perfect for insulating hard-to-reach areas like attic corners or inside existing walls.

A few other things…

If you’re looking for a green option, blown in insulation is the more environmentally friendly way to go because it is more energy efficient and it is made of recycled materials. Keep in mind, however, that one of these recycled materials is paper. Blown in insulation is treated so it’s fireproof, but it is not waterproof. This should not be a problem unless you are intending to install it in an area prone to condensation, leaks or flooding. As your local source for blown in insulation in Fargo, ND, we can work with you to determine if moisture will be a problem.

Overall, we recommend using blown in insulation over rolled insulation in most cases, but there are some times when rolled insulation may be the better choice. As your local insulation experts, the team at Interstate Insulation can work with you to determine the type of insulation that will work best for your project. To get started, give us a call today!
