Attic Insulation
Insulation in your home provides resistance to heat flow. The more heat flow resistance your insulation provides, the lower your heating and cooling costs. Properly insulating your home not only reduces heating and cooling costs, but also improves comfort.
When considering insulation, the attic is generally the first place to start, as most of your heat will rise and go through your ceiling to the attic if there is inadequate or ineffective insulation. It is also often one of the easier places to access.
