The most common form to insulate a home from heat, cold and even sound waves is a roll or blanket insulation. They are rolled and made of fiberglass and is at least expensive cost. Use our roll insulation calculator to determine how much insulation you need to purchase for your home. Our attic insulation calculator uses the values of width and length of the area which needs to be insulated as input to calculate total square feet need to be insulated.
Calculate the fiberglass roll needed to be filled in a room of width 10m and height of 25m?
Square feet needed = 10 x 25
Therefore the approximate square feet of insulation material needed is 250m².
