Use it in your ATTIC to reflect the summer heat back up to the attic ceiling. Just staple it up to the attic ceiling across your attic. I placed styrofoam sheets 1/4 inch thick in my attic.... and reduced my attic temperatures from 140 degrees down to 110 degrees. This brought my HOUSE temperatures down from about 93 degrees to about 82 degrees. Now i dont need to use my air conditioner much in the summer!!! I wish i had put reflective mylar up there instead of the styrofoam though. Then i could have ADDED the styrofoam later. BE SURE to have ventilation out the attic for the space ABOVE the mylar and other ventilation for attic BELOW the styrofoam to assure your attic does not retain moisture. That is a VERY good use for your mylar.
