Rolled Insulation Prices #
Rolled insulation, often called "batt and roll insulation" is the classic material for home insulation. Batt and roll is typically a fiberglass based product. It provides great heat and cold insulation. It also can be really itchy during installation. That is one of the drawbacks of installing fiberglass insulation if you're the one installing it.
Fiberglass roll insulation is the more economical choice when it comes to choosing insulation. It cost $.70 to $1 per square foot to install. For the typical 2,400 square foot home it will cost $1,700 to $2,400 to install rolled insulation. That is the average cost and varies with where you are located and by the size of the job. Generally, you can get a better price for larger projects.
Blown Insulation Prices #
Blown in insulation is made of cellulose fibers. This type of insulation was invented in the 1920s. It became an advantage to builders to use this type of insulation because it saved them money on supplies. It is possible to reach the same R value using less of this spray insulation than using the typical rolled insulation.
Today, blown in cellulose insulation costs between $.75 and $1 per square foot. For the average 2,400 square foot home it will cost $1,800 to $2,400 to have this kind of insulation used in your home. Some people are reluctant to use this type of insulation because it has caused problems with mold in the past.
Spray foam Insulation Prices #
Spray foam insulation is the new thing in insulation and is going to be the future of insulating homes. Of course it costs more. It costs $1.25 to $3.50 per square foot to install spray foam insulation into your walls, ceiling, and attic. For the average 2,400 square foot home it will cost $3,000 to $8,400 to do the entire home. It is a versatile insulation and can be used anywhere roll insulation can go. It takes more skill to install than other types of insulation which is part of the reason it costs more than the others.
It may cost more up front but it will yield savings in heating and cooling costs over the years. For this reason having blow in insulation is a great bragging material when selling a piece of property. It will raise the value of your property.
Spray foam insulation is a polyurethane product. It expands many times over until every crevasse is filled. It has a great R rating value which makes it a very good insulator. It has an R rating that falls between 3.5 and 6.5 per square inch, depending on the product.
