The under-insulation of homes is a huge problem that has a far-reaching negative impact on climate change and poverty. The North American Insulation Manufacturers Association (NAIMA) reported that approximately 90% of U.S. single-family homes are under-insulated and are wasting energy and money, as well as decreasing homeowners’ comfort levels. A little over 14% of all energy use in the United States is consumed in homes, and heating and cooling is one of the biggest energy uses in the home. NAIMA estimates that, on average, properly insulating older homes will keep an average of one ton of CO2 out of the atmosphere; this is not a one-time savings but year after year for as long as that house is in use.
