Insulation

Whether you live in a warm or a cold climate, adequately weatherizing and insulating your house has many benefits. Most importantly, you save money. Even in homes with average insulation, heating and cooling costs account for more than half of the total energy bill. And because most insulating and weather-stripping products are relatively inexpensive, and investment in them can be recovered through energy savings in a short period of time.

A well-insulated house not only saves money, it's easier on the environment because it uses less energy. By reducing energy use, you help reduce pollution and slow the depletion of natural resources. In an average home in a cold climate, it is estimated that reducing energy usage by only 15% can save the equivalent of 500 pounds of cola each year. Finally, a tightly sealed, well-insulated house eliminates drafts and cold spots, creating a more comfortable home for you to enjoy. The three types of insulation you are most likely to encounter are fiberglass, cellulose, and rigid foam.
