Owners of
Existing Homes – Retrofits:
How do I know if I need to add more insulation
to my home?
Any one of the following conditions can be an indicator
of inadequate insulation:
- Heating and cooling bills are high
- Rooms in the home feel drafty
- Snow melts quickly off the roof
- The furnace or air conditioner runs constantly
- Outside noise is audible inside the house
- Icicles and ice damming occur on the roof
Ice Dams
Ice
dams not only indicate inadequate insulation, they can
cause damage to the structure of the house. Heat escaping
from the house through a poorly insulated attic warms
the shingles on the roof, melting the snow, which runs
down the roof to the eaves. Since the eaves overhang
the house and are cold, the melted snow freezes when
it reaches the eaves. When enough ice
has formed at the eaves, it begins to stop or
dam additional water from draining off the roof. The
ice dam eventually grows under the shingles, causing
melted snow to enter the ceilings and walls.
Determining Additional Insulation
Needs
The
best way to determine if you need additional insulation
is to measure the depth of insulation currently in your
attic. If there is less than R-49, (19 inches of blown
fiber glass, or
12-13 inches of cellulose), you could benefit by adding
more insulation to your attic.
If your attic has ample insulation and your home still
feels drafty and cold in the winter, or too warm in
the summer, the exterior walls may not be well insulated.
Basements and crawl spaces need proper amounts of insulation
as well. Of course, doors and windows should also be
checked for air tightness.
Heat escaping through the attic may be responsible for
up to one half of your home's heat loss. Adding insulation
here is one of the best ways to improve your home's
energy efficiency.

Adding Nu-Wool Insulation will help keep the heat where
it belongs — in the house in cold weather and
outside the house in hot weather.
