How much rolled insulation do you need for a house?

Answer by  Latin4 (11170)

Take this information to a local home store. Tell them what you are using this for. There are different types of insulation, grades, sheet vs rolled. Also the local city department has information for this type of work. Check and see if you need a permit.

You could do some math to get an answer. Calculate the surface area of surfaces to be insulated. This will give a rough estimate of the amount of rolls needed.
