To prevent air leaks, caulk your windows
and doors. If possible, replace old windows with energy efficient
ones.
Tips when shopping for windows
When you're shopping for
new windows, look for the Energy Star label; it means that the windows are performance certified.
Remember, the lower the
U-value, the better the insulation. In
colder climates, a U-value of 0.35 or below is recommended.
In warm climates, where summertime heat gain is the main
concern, look for windows with double-glazing and special
selective coatings that reduce heat gain.
Select windows with air
leakage ratings of 0.3 cubic feet per
minute or less.
In temperate climates
with both heating and cooling seasons,
select windows with both low U-values and low solar heat gain
co-efficiency (SHGC) to maximize energy benefits.
Look for the ENERGY
STAR® and EnergyGuide labels.
Cold-Climate Window Tips
Install exterior or interior storm windows; storm
windows can reduce heat loss through your windows by 25% to 50%.
Storm windows should have weatherstripping at all moveable
joints; be made of strong, durable materials; and have
interlocking or overlapping joints. Low-e storm windows save even
more energy.
Repair and weatherize your
current storm windows, if necessary.
You can save 10% or more on
your energy bill just by reducing the air leaks in your home.
Install tight-fitting,
insulating window shades on windows that feel drafty after
weatherizing.
Close your curtains and
shades at night; open them during the day.
Keep windows on the south
side of your house clean to maximize solar gain.
Warm-Climate Window Tips
Install white window
shades, drapes, or blinds to reflect heat away from the house.
Close curtains on south-
and west-facing windows during the day.
Install awnings on south-
and west-facing windows.
Apply sun-control or other
reflective films on south-facing windows.
Insulation Tips
Consider factors such as your climate, building
design, and budget when selecting insulation for your home.
Use higher density
insulation, such as rigid foam boards, in cathedral ceilings and
on exterior walls.
Ventilation plays a large
role in providing moisture control and reducing summer cooling
bills. Attic vents can be installed along the entire ceiling
cavity to help ensure proper airflow from the soffit to the
attic, helping to make your home more comfortable and energy
efficient.
Recessed light fixtures can
be a major source of heat loss, but you need to be careful how
close you place insulation next to a fixture unless it is marked.

your local building codes for recommendations.
When installing insulation,
follow the product instructions on installation and wear the
proper protective gear.
