Insulation is an important part of your home's construction and essential for keeping your
home as quiet, comfortable and energy efficient as possible. Here you will find lots of useful
information that explains how home insulation works and what kind of insulation to use. And
remember: we're here to help you do the job right!
Insulation is one of the smartest investments you can make in your home because it provides
year-round comfort and savings in three important ways:
Lower energy bills
Insulation keeps your home warmer in the winter, which lowers your heating costs. In the
summer, insulation keeps your home cooler, which eases the load on your air conditioner.
Quieter, more comfortable living
Insulation can actually absorb sound, reducing the unwanted noise from appliances, audio
equipment, conversation and other sources of sound that are transmitted through your walls and
floors. Insulation also keeps your family more comfortable by making it easier for your furnace
or air conditioner to maintain a constant temperature.
Healthy home, healthy environment
Reducing your family's overall formaldehyde exposure can make your home healthier and safer.
Fiber glass insulation helps prevent the growth of potentially hazardous mold and mildew in your
walls, air ducts and ceilings that can result from trapped moisture.
Where Should I Insulate?
The more you insulate, the more your energy savings can add up. Insulating attics, walls,
ceilings, and crawl spaces can have a dramatic effect on your energy savings, and can create a
more comfortable home year-round.
Insulating for Optimal Results
The thermal envelope establishes a boundary. Heated and/or cooled areas are entirely enclosed by
the envelope. Unconditioned spaces such as the attic, crawl spaces and the garage are outside the
thermal envelope. You should insulate all exterior walls that separate conditioned spaces from
unconditioned spaces. Insulating attics closes the thermal envelope from above.
