How Much will you Pay for Blown-in Insulation?

If you’re on a mission to increase the comfort of your home, blown-in insulation could be a worthwhile investment. Like all other home improvement projects, the cost of installing it is a top consideration. We’ll go over a few factors that affect how much you’ll pay to have a blown-in insulation system in your home.

Why blown-in fiberglass insulation?

A major benefit of this system is that it will generate huge energy savings and is more affordable than other options like cellulose. Blown-in insulation increases the R-value of your home, making it more energy efficient so you’re able to save on the overall cost of heating and cooling.

How much you pay for the process will depend on the labor required and the R-value you wish to achieve in your home as well as the materials you choose to use. For instance, if you live in a colder region and want an R-value of around 30 in your attic, more labor hours will be required to achieve a certain level of thickness so expect to spend more.

Blown-in cellulose insulation

Cellulose is sometimes used as an alternative to fiberglass because it’s a more natural product made using recycled products like cardboard and newspaper. This insulation is then treated using a fire retardant called borate to make it resistant to fires as well as mold and mildew. Since cellulose is an eco-friendly insulation product with better properties than fiberglass it’s usually more expensive. Expect to pay about $30 for a 19lb package of blown in cellulose insulation that covers about 40 sq. ft. of space at the recommended R-value. On the other hand, a package of 19lb blown in fiberglass insulation may cost you the same but cover more space (about 150 sq. ft.).

How much should you spend on the attic insulation?

The recommended R-value for attic insulation is 30. This attic insulation will help you achieve optimal thermal efficiency and reduce expenses related to heating and cooling. Attics are usually large, open spaces so the process of insulating them doesn’t require labor-intensive techniques or specialized equipment that will make it costly. Expect to pay about $40 to $70 an hour for labor and about $500 to $1000 for materials for an attic space of about 1000 square feet.

Insulating the walls and floors

Blown-in insulation in the walls and floors is a bit more complicated than attic insulation and is likely to cost more. Before the installation is done, the technician needs a proper understanding of what’s behind those walls and flooring such as the electrical wiring and outlets in order to know just where to drill the insertion walls and the maximum achievable R-value. Unlike the attic space, the space inside of a wall or floor is much smaller which contributes to a lower R-value than for these areas. However, insulation is just important in walls and floors as it is in the attic space. The process is likely to cost you about $1200 to $1800 for materials and labor.
