Insulation reduces the heat flowing out of your home during the winter months. Ensuring that your home is properly insulated will help your save energy when the temperatures drop.
- Insulate your attic. In older homes, thin can be the most cost-efficient way to cut home heating costs. Prior to energy efficiency standards, homes were often built with little or no insulation. As a result, large amounts of heat is lost through walls, floors, and ceilings.
The amount of insulation that you should install depends upon where you live. Insulation is measured in R-values, or the resistance to heat flow. The higher the R-value, the less resistant the product is to heat flow. Ask the salesperson at your local hardware store about the recommended R-values for your location.
- Weather-strip and insulate your attic hatch or door to prevent warm air from escaping out of the top of your house. Since warm air rises, this type of heat escape is common.
- Seal holes in the attic that lead down into the house, such as open wall tops and duct, plumbing, or electrical runs. Any hole that leads from a basement or crawlspace to an attic is a big energy waster. Cover and seal them with spray foam and rigid foam board if necessary.
