I have used this product in every room I have...I have used this product in every room I have gutted in an old house, including the ceilings. It is dusty to work with, wear a mask, but has significantly improved the warmth and coolness of the rooms I have done. The product used in the ceilings was very helpful in noise insulation - our kitchen is right below our teenage gamer - so cutting down on the commentary from his room was key. I love the product and will continue to use it in my own home.
