How to Determine the Amount of Cellulose Insulation Needed for a Project How to Determine the Amount of Cellulose Insulation Needed for a Project
Cellulose insulation is a very environmentally friendly way of keeping your home energy efficient. This type of blown in insulation is made up of recycled newspapers and other types of organic materials. After they are coated with a flame retardant chemical, they are ready to be used in your home. Before using this cellulose insulation, it is important to know how much you need to use. It is important not only to have enough, but also for the weight calculation.
Step 1: Measure Insulating Area
Use your measuring tape, and take the measurements for the height and width of the area where you are going to be using the cellulose insulation. You will also want to know the thickness of the wall. The thickness of the wall should be measured from the back of the drywall and the exterior shell.
Step 2: Calculate Cubic Footage
For many projects, you only need to find out the square footage of an area. However, now you're working with something that takes up volume within your home, and you need to find out the cubic footage. Find this number by multiplying the height by the width by the depth of the wall.
Step 3: Calculate Weight
The cellulose insulation needs to be at a weight of 2 1/2 to 4 pounds per cubic foot. Determine this by multiplying the weight number of the insulation by the total cubic footage.
