HOME ENERGY EFFICIENCY - Insulation |
Why Insulate Your House?
Heating and cooling account for 50 to 70% of the energy used in the average American home. Inadequate insulation and air leakage are leading causes of energy waste in most homes. Insulation:
- saves money and our nation's limited energy resources
- makes your house more comfortable by helping to maintain a uniform temperature throughout the house, and
- makes walls, ceilings, and floors warmer in the winter and cooler in the summer.

Plug Those Drafty Walls
Cracks that let air escape right through your home's insulation rob you of heat. These leaks are common in the walls of most homes. And they also occur around doors, chimneys, plumbing vents, foundation cracks and other exterior wall openings.
If you have a new home, it may have been insulated with the latest techniques--using gaskets, caulk and plastic.
But if you're not so fortunate, you can rely on a long-lasting, flexible caulk and a can of expanding foam to plug the leaks. It helps to think of the inside of your interior walls and ceilings as air barriers. You can seal with caulk all the edges and the places they intersect, such as electrical boxes and windows.

Windows
Windows can account for 33% of the total heat loss and as much as 75% of the heat gain during the summer. That's why it's a good idea to replace single-paned windows with double-paned, low emissivity coated windows.
Although new windows can be expensive, they offer a great potential return on investment through energy savings as well as the increased home value they will definately create. |
Basics of Insulation
Did you know that insulation installed in homes and buildings saves over 400 trillion BTU’s annually—enough to power the state of Florida for 4 years?
A recent Harvard study on energy consumption found that nearly 65% of U.S. homes (45 million total) have insulation levels that are below the 2000 IECC (International Energy Conservation Code) levels. This translates to more than 800 trillion BTU’s (British Thermal Units) that could be saved each year. Properly insulated new homes would save 300 billion BTUs each year. This equals 28 supertankers of crude oil and 300 billion cubic feet of natural gas.
So, when you think insulation, you’re well on your way to reducing energy costs. Adding fiber glass insulation above minimum building requirements whether in a commercial or residential space significantly increases energy savings, and enhances the overall quality of your indoor environment. |
