Insulation is one of the most important yet overlooked parts of a house. Proper insulation can make living in your house more comfortable, and save you money. Insulation works by keeping the interior of your home the temperature you want it at. For instance, if your air conditioner is on it will keep the cool air in your house, and if your heat is on it will keep your house warm and toasty. It works by not letting the indoor air that is at the desired temperature escape and keeping the outdoor air out.
