Weatherization is the first line of defense when looking to save energy in the home. Heating and cooling costs account for almost half of our household energy costs. While we all know the blocking drafts during the colder months of the year will reduce heating costs, it’s also important to realize that weatherization measures will cut cooling costs in summer by reducing the loss of cooled indoor air. Weatherization measures are the least expensive ways of saving energy in the home. Most of the products we carry, such as window insulation kits, caulking supplies, foam insulation and draft guards costs less than $10. And these products are easy to install by the homeowner – no professional help is required.
