We didn’t experience cold weather anything like what recently struck the Midwest and Eastern US. However, the intense cold weather can serve as a warning to everyone—many homes do not have proper levels of insulation. The North American Insulation Manufacturers Association estimates that 90% of homes are under-insulated.
Poor insulation means immense amounts of energy go to waste attempting to make up for the heat that escapes through the walls of a home. According to the Environmental Protection Agency, a house can save around 15% on its annual heating and cooling bills with better insulation.
Newer building codes have improved insulation, but there are many older buildings still around with subpar heat sealing on them. You might be living in one of those and paying higher bills than you should without realizing it.
