How do you calculate square footage for blown in insulation?
Determine the square footage of the area where the insulation is to be installed. Measure the length and width of the area. Multiply these to numbers to get the total square footage.
How do you estimate insulation?
To determine the amount of insulation needed, start by measuring the height and length of each of your room walls. Multiply the wall’s length by the wall’s height and don’t forget to write down the spacing of the studs so you can then determine what type of the insulation will be purchased.
How thick should blown in insulation be?
about 7.5 inches
When blown into attics and wall spaces, loose-fill fiberglass offers an average R-2.5 thermal value per inch (the higher the number, the greater the insulating effect). You’d need a thickness of about 7.5 inches of insulation to match the insulating value of a batt of R-19 insulation (R-19 is a common batt value).
How long does it take to blow insulation into attic?
It takes one person about 25 minutes to blow one bag of insulation into the attic. The number of days for project completion depends on how many workers are present. Materials chosen – there’s a huge difference in price between the oft-used cellulose and fiberglass vs. natural wool per square foot.
How much does a bag of blown in insulation cost?

How many bags of insulation do I need for attic?
How many bags of insulation do I need for attic? For example, if the square footage of the room you’re planning on insulating is 1,000 square feet and you want to achieve an R-value of 60, you will need approximately 17 bags to fully insulate your room.
How big is a dense pack insulation wall?
Dense Pack Sidewalls: R-13, 2” x 4” wall, (30lb./bg) = 27 bags Dense pack Sidewalls: R-20, 2”x 6” wall, (30lb./bg) = 40 bags * 30lb. bag dimension = 14” x 15” x 28” long or 3.4 cu./ft. per bag Loose Fill Attics: R-30, 10.5” deep, (33lb./bg) = 13 bags Dense pack walls: R-13, 2” x 4” wall, (33lb./bg) = 13 bags
