How many insulation batts do i need

The next step in this process is to select the type of insulation needed. Some of the most used types are:. 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. You will need this as insulation normally comes in precut lengths or standard rolls designed to fit exactly into between studs. These amounts will make up for odd cavities, nonstandard framing distances and even waste amounts. Make sure that all rooms have been measured and that the stud cavity is the same for the entire house.

Sometimes, due to modifications to structures, the depth might not be the same. Now, that we have determined the amount of square foot required, we need to divide that amount by the square footage supplied in the package. Make sure to check as every manufacturer has its own dimension or size of insulation.

That number will be the number of bundles needed to insulate the walls of your home. Another way to properly calculate and estimate the amount of insulation needed is by using computer software. Some programs will allow you to integrate blueprint takeoff for larger projects, and even can be connected with QuickBooks. This software can be used to automate the process and reduce the guess when estimating insulation from construction drawings.

Now, that you have determined how much insulation you need, is time to set a price or determine the cost to actually install the insulation. This number will depend on the amount of R-value and the room configuration. Write down both measurements beneath the wall's area.

Move around the house determining the area, depth and stud cavity width of each house wall. Make sure to keep the dimensions next to each wall. Add the area of each wall that has the same stud cavity width and depth.

Include height if you're estimating batt insulation that is cut to length. Keep each required batt size separate. Divide the total square footage for each insulation size by the square footage supplied in a package in of insulation to determine the number of insulation bundles needed to insulate the walls of your home.
