Step 1
Grab your house plans and make a list of the areas that will need insulation. This is best to do in a numbered list that you can reconcile with the plans. This list should include all walls, floors, ceilings, crawlspaces and the attics.
-
Step 2
Decide which areas will get batt insulation and which will have other forms of insulation. Generally, blown insulation is used for walls, but batt can be, too. Batt is also used for crawlspaces, attics, floors and ceilings because of the small areas needed for access.
-
Step 3
Take measurements of the areas for the batt insulation. Since batt insulation comes in rolls, you need to know how long a section a roll will cover. This should be done first by noting the lengths of each of the areas for the insulation, then finding the square footage you need. This will be best for ordering purposes, though linear footage will be used to cut and install the insulation.
-
Step 4
Comparison shop the batt insulation in your area and online to find the best deal. Multiply the cost by roll to estimate the entire cost, estimating a slight overage. Also, ask about whole house discounts, as you can sometimes get a discount by purchasing all your insulation materials with one business.
