Tips to Warm Your Winter from Union of Concerned Scientists
Insulation prevents heat from leaking out of your home in winter and into your home in summer, making it more comfortable year-round and reducing your energy consumption, global warming pollution, and heating and air conditioning costs.
The many options on the market today include fiberglass rolls, spray foam, rigid foam, and loose-fill cellulose made from old newspapers. To determine the best fit for your needs, consider these factors:
R-value. This number represents an insulation’s ability to resist heat; the higher the R-value, the more effective the insulation. The U.S. Department of Energy recommends specific R-values for different areas of your home, based on where you live and what heating fuel you use (see the related links). If space is limited, choose the option with the highest R-value for the given thickness you need.
