What is the least expensive material to insulate an attic?
Fiberglass is the most common and least expensive material used to insulate attics. Blown-in fiberglass insulation doesn’t settle after time has elapsed, so if you blow in 16.5” of fiberglass, it will remain at 16.5” of fiberglass.
What is the R value of insulation?
The cost of the job will depend on the amount of blown-in insulation R-value used or how much R-value you desire. R-value is defined as a material’s ability to slow the heat traveling through it. The higher the R-value, the more it slows the escaping heat and the better your home is insulated. Recommended R-values run from R25–R60, depending on the climate where you live. Very cold climates need a higher R-value.
How much does it cost to seal an attic?
Typically, the cost for air sealing runs from $350 to $1,500. If you have a complex attic with lots of ductwork, bathroom fans, and ceiling fixtures, more air sealing will need to be done. Use expanding foam or caulking to seal any air leaks in your attic.
New work requires netting
In new construction, dense-packing insulation requires stapling an air-permeable netting (Insulweb is the brand we use) over the framing to contain the insulation while we dense-pack.
Getting the right density
To achieve the critical 3-1/2-lb.- to 4-lb.-per-cu.-ft. density, installers need to fill the cavities with a small-diameter hose. Our blowers are connected to a hose that steps down gradually. First there’s 100 ft. of 3-1/2-in.-dia. hose connected to 50 ft. of 2-1/2-in.-dia. hose, which ends with a 6-ft.-long 1-1/2-in.- or 2-in.-dia.
Having the right stuff
Our company carries insulation and equipment in our two 20-ft. Isuzu box trucks equipped with Accu1 9400 cellulose blowers. The blowers are reliable and easy to field-repair, requiring only a few simple tools and a small collection of spare parts.
A dense-packed day in the life
We typically run a three-person crew. When we get to the site, two people begin air-sealing and installing the netting that holds the cellulose, a process we call netting. The third runs power to the insulation blower and runs the hoses to the work area.
What Is Blown-In Insulation?
Blown-in insulation is a loose-fill material blown via machine into otherwise uninsulated cavities. Blown-in insulation is one of the many material types that can be used to insulate a home. It comes in three basic types - fiberglass, cellulose, and rockwool. Cellulose can be further broken down into two categories - wet spray and dense pack.
Blown-In Insulation Cost by Type of Installation
Most blown-in insulation is added to existing homes. The material means it is easier to blow it into existing spaces, adding insulation to places that batts or spray foam have a hard time reaching. You can use blown-in insulation in some areas of new construction.
Cost of Blown-In Insulation per Square Foot
The cost of blown-in insulation averages $1.65 to $3.80 a square foot. Total costs vary due to how many inches of insulation, material, and where it is going. Typically, in-wall insulation can only use about 5 inches of material at once, but you can use up to 18 inches of material on an attic floor.
Average Cost of Blown-In Insulation by Material
Three materials create blown-in insulation - fiberglass, rockwool, and cellulose. Cellulose can be broken down into two types - wet spray, which is used in vertical applications and exterior walls, and dense pack, which can be used in attics, crawlspaces, and other open areas. Each material has costs, pros, and cons to consider.
How Many Bags of Blown-In Insulation Will You Need?
All blown-in insulation is sold in bags. The number of bags needed to complete a job varies, depending on the square feet you need to cover and the insulation depth. The deeper the insulation, the higher the material’s R-value or insulating factor.
What Is the R-Value of Blown-In Insulation?
R-value measures how well a material resists thermal transfer. The higher the number, the better job it does at insulating. Most materials are given an R-value at 1 inch of thickness. The thicker the amount of material, the better the total R-value. Below are the R-values for each cellulose type when measured at 1 inch in depth.
