You might be wondering were the insulation is. Well it is no longer on the floor of the home and is located on the wall. Our SilverGlo insulation is under the CleanSpace and won't be a breeding ground for mold because it isn't made of organic material. Now the crawl space will remain about the same temperature as upstairs because we have blocked the vents and doors. We don't even have to heat or cool the space. It stays comfortable all year round!!!
