Blow-in Insulation: What Is It and What Are Its Advantages?

According to roof repair experts, insulation is a very important component that homeowners should keep in mind. After all, it not only keeps your home at a comfortable temperature no matter what time of the year it is but it also helps prevent your roof from sustaining damage from too much heat or cold. Of the numerous options that you have when it comes to insulation materials, blown-in insulation has numerous advantages for any home.

Here, 3JM Exteriors, Inc. reveals the advantages of blown-in insulation.

Easy to Install

Whether you’re conducting a DIY or you’re having a professional install your blown-in insulation, roof repair and insulation experts say that this material is one of the easiest to install around your home compared to other insulation material. This is because thick blankets of insulation can easily be blown across your attic’s floor through a single hose that runs up through the attic hatch, allowing it to cover every inch of the room within an hour or two.


In terms of material costs, professionals say that blown-in insulation has the advantage as blow-in cellulose costs around $30 for a 19-pound bag, which can cover around 40 square feet of your attic at minimal R-value.


Compared to fiberglass batts, blown-in insulation has a higher R-value, allowing it to keep your home more comfortable compared to other insulation materials. In fact, blow-in cellulose has an R-value of 3.2 to 3.8 per inch while fiberglass batts only offer an R-value of 3.7 per inch.
