Here are a few things to think about before you install:

• Leave fiber glass insulation in its packaging until you're ready to use it.  Packaged insulation is highly compressed and expands greatly when the package is opened.
• Use continuous rolls in floors because of longer joist spans.
• To cut insulation, lay it on a board with the kraft or foil facing down, if applicable.  Lay a yardstick (or 2 x 4) over the area of insulation to be cut. Press your straight edge down hard and cut with a utility knife, using the straight edge as a guide.
• Do not compress the product when you install it. The insulation should be in full contact with the studs or drywall on all sides and the front and back.
• Avoid leaving any gaps around the edges or around pipes or wiring.
• Look for specific guidance when installing insulation around pipes and wiring.
• Do your homework to see if you need a vapor retarder.

Think you need more insulation?

• If your home was built before 1980. Only 20% of homes built prior to 1980 are well insulated.
• If you are uncomfortably cold in the winter or hot in the summer. Adding more insulation creates a more uniform temperature, and increases comfort.
• If you're building a new house or addition, or installing new siding or roofing, it's a lot easier to access the areas that need insulation.
• If you notice your energy bills seem to be steadily rising.
• If you're bothered by noise from the outdoors-insulation helps to muffle sound.
• If you are concerned about the effect of energy use on the environment.
