Now Is the Perfect Time to Check Your Home’s Insulation
(ARA) - The cold and snow have arrived, which means
it’s a great time to make sure your home has enough insulation in the
attic. If you can see the wood beams of the attic floor, it’s probably
under-insulated. What you find out will help you keep your house warmer
and save you money for years to come.
Measure the depth of your insulation. If it’s less than 15.5 inches,
you’re literally losing heat and money through your roof each year. With
home heating prices taking a hefty hike this winter, adding insulation
to your attic is one of the easiest ways homeowners can fight back.
Think of it as an investment that pays for itself year after year.
According to the U.S. Department of Energy, 80 percent of homes built
before 1980 are not insulated to government standards. Even newer homes
may not be as energy-efficient as you think, since state energy codes
are only the minimum insulation requirements for new construction, not
the amount recommend to optimize energy efficiency. So the only way to
know for sure if you have enough insulation is to get up in the attic
and measure.
Insulating your attic not only helps keep your heat and money at home,
but is good for the environment too. A recent study by the McKinsey
Global Institute concluded that insulation is the single most
cost-effective way to reduce greenhouse gas emissions. Bringing the
estimated 60 million under-insulated attics up to Department of Energy
guidelines could save the equivalent of 103 million barrels of oil each
year -- that’s 51 supertankers full.
If a warmer home, reduced energy bills and a greener planet aren’t
enough incentive to add insulation, many states and utilities offer
additional incentives too, so be sure to check for local rebates.
How much insulation do I need?
The amount of insulation needed varies depending on the region of the
country where you live. In most cases, the Department of Energy
recommends attics be insulted to R-49. The R-value represents thermal
resistance to heat flow, so the higher the R-value, the greater the
insulation effectiveness. Attaining an R-49 value requires15.5 inches of
fiberglass blanket insulation or about 18 inches of blown insulation. To
assist homeowners in determining the amount of insulation needed to
achieve recommended R-values, Owens Corning, maker of PINK Fiberglas
insulation, has created a special Web site,
www.InsulateYourAtticNow.com. Simply enter the square footage of
your attic and the thickness of insulation you currently have, and it
will tell you your current R-value and how many rolls of insulation
you’ll need.
Installation is easy
Most do it yourselfers prefer fiberglass insulation, which comes in easy
to install rolls or bats. Widths correspond with standard spacing of
attic floor joists (beams) and lengths can be easily cut with a utility
knife. If your attic currently has no insulation, purchase paper-faced
rolls that include a vapor barrier. The vapor barrier should face down
in an attic. If your current insulation already has a vapor barrier, use
unfaced insulation.
When installing insulation in your attic, you’ll want to lay down boards
or a sheet of plywood over the rafters to sit on while you work. If
joist cavities are not completely filled with insulation, fill them
first. Once the joist cavities are filled, then lay the insulation
crosswise, perpendicular to the joists. Be sure to wear work gloves,
safety glasses, a dust respirator mask and a long-sleeved shirt. You’ll
also want a utility knife and straightedge for cutting the insulation, a
tape measure, portable work light and a stapler.
