How Do You Calculate Blown Insulation Coverage In An Attic?
Whether you are insulating a space for the first time or adding additional insulation, you will need to know how much insulation to buy. It would be very frustrating to begin a blow-in insulation job (setting up the machine, getting all your safety gear on, etc.) only to run out of insulation material before completing the job. Determining the amount of insulation needed is a reasonably easy and quick task that can save you some headache later. Determine the square footage of the attic space. Use a tape measure to get the length and width dimensions. Multiply these together to determine the square footage. For instance, if the attic is 12 feet by 20 feet, the square footage will equal 240 feet. Measure the existing insulation depth. Use a tape measure to check the distance from top of the insulation to the attic floor. If there is no insulation installed, or if you are removing the old insulation, you can eliminate this step. Determine the R value that you want to achieve. The R value
