Attic Insulation
Your attic is a very important consideration in determining the energy efficiency of your home. An attic that is not insulated will be cold during the winter and boiling hot during the summer, thus causing your furnace and air conditioner to work harder. A well-insulated attic leads to bills and less frequent repairs of major HVAC appliances.
Instructions
1. Go up into your attic and inspect for insulation. If your attic has insulation but you can still clearly see the joists, or if you find a leak in the attic roof, you need new insulation. If your attic has no insulation at all, you'll soon enjoy lower energy bills.
2. Take measurements to estimate how much insulation you'll need.
3. Go out to your local hardware store and purchase batt or fiberglass roll insulation. You can purchase blown installation, but you will have to rent an insulation blower and follow strict safety guidelines (for this insulation method it is best to hire a professional). Minimum recommended R-values are:
* R-49 for the U.S. northeast, north, midwest, northwest, and southwest
* R-38 for the Texas and Louisiana coastline and Florida, Hawaii, and California
4. Install insulation between the joists using manufacturer's instructions. If using batts, make sure to close all seam gaps between batts. Also make sure not to compress insulation when installing it.
