Sealing & Insulating
Keep it in, keep it out—this isn't a child's game, it's a ground rule of home energy efficiency as it relates to the movement of air in your home. Try these techniques on for savings.
Add it up. The recommended insulation level for most attics is R-38 (or about 12-15 inches, depending on the insulation type). In the coldest climates, insulating up to R-49 is recommended. If your insulation is level with or below the attic floor joists, you probably need to add more. Check out this helpful fact sheet about insulation.
Analyze and seal. Insulation is just part of making your home more efficient. Sealing air leaks is very important, but don't seal too tightly. Hire a home energy rater like Energy Smart Home Improvement, an iConservePA partner, who can analyze your home with diagnostic tools, make strategic recommendations, and perform the improvements themselves or refer you to someone who can. The PA Energy Store, another iConservePA partner, can arrange such services.
Reflecting about conservation? Applying reflective window film can result in significant savings in the cost of cooling your house in the summer and warming it in the winter. In addition to conserving energy, window films can enhance privacy, reduce glare, and limit harmful UV radiation. They are inexpensive and easy to install. Window films can be purchased at Lowes, Home Depot and other retailers.
