INSULATION & WINDOWS: It's What's Upstairs That Counts
No matter where you live, your home will be more comfortable and cost less to heat and cool with the right insulation. That could mean more money in your pocket all year round.
Unless your home was designed with energy efficiency in mind, adding insulation can be a good way to save money. Most older homes were built without much insulation, which can mean high energy bills. Even if your home is new, more insulation can pay for itself in a few years and increase your home’s resale value.
ATTIC ENERGY SAVERS
- If you're in the market for new windows, consider high-efficiency alternatives. Look for the National Fenestration Rating Council (NFRC) label, an independent industry rating system for the energy performance of windows, doors, and skylights.
- Look for windows made of low emissivity—or “low-E”—glass. Low-E glass has a special thin coating that lets in light, but reduces heat transfer. In warmer climates, consider windows with “spectrally selective coatings”—glazes that let light in, but keep heat out. In colder climates, select windows that are gas-filled to reduce heat loss.
- Plant a tree. Landscaping is a natural way to shade your home. Well-placed trees and shrubs not only save on air conditioning costs, but add value to your property, too.
- Shade room air conditioners from direct sun to reduce their workload. Clean the filters once a month and replace them as necessary.
The ABCs of Insulation
The FTC requires insulation manufacturers and sellers to test and label their products. Generally, the higher the “R-value” the more energy you can save. When you buy insulation, installers and retailers have to give you an R-value fact sheet. New home sellers must give you information about the type, thickness, and R-value of the insulation in each part of the house. Many state or local building codes include minimum requirements for home insulation. Be sure your new home or home addition meets those codes. It will save you money in the long run.
The amount of insulation you need depends on the climate, the part of the house, and the type of heating and cooling systems (gas, oil, or electric) you have. Your attic is the best place to start. The Department of Energy has an online calculator to help you decide what’s right for you. Visit the Zip Code Insulation Program website.
