Insulating the cement floor in your basement with Owens Corning Celfort® 200 2X8 sheets or CodeBord® 4x8 sheets is easy. Both products can be used for this application. To find that out how many sheets you need, calculate the total area of your home to determine the amount of sheets: multiply the floor length by the floor width, in feet, and then divide the total area to be insulated by measurement of the sheet.
For example:
• If your home basement floor is 10 ft (floor length) x 10 ft (floor width), the total square area of the floor = 100 ft2.
• Divide the coverage area by sheet, or 16ft for 2X8 sheets, or 32 ft for the 4x8 sheets.
• Number of sheets required = 6.25 (7 sheets) for the 2x8 dimensions, or 3.125 (4 sheets) for the 4x8 dimensions.
