When
considering new windows for your home, be sure to ask your window
contractor the following questions:
-
What options
do you carry for high-performance windows?
-
Do your
products feature low-conductivity spacers (non-metal), and are
they at least 1/2 – in wide?
-
What frame
materials are available (metal, wood, fiberglass, vinyl
V-insulated or non-insulated)?
-
What
justification can you offer to convince me to upgrade to a
better window?
-
How long is
the typical payback period (the time it will take for energy
savings to offset the costs of added efficiency), and do you
have documentation to verify your claims?
-
What is the
R-value of the glass (rated from 1 to 5, with 5 being the best)?
-
What is the
ER rating (Canadian Energy Rating System) of the window (from
-50 to +15, with +15 being the best)?
-
How will
replacing the windows affect the air quality in my home?
-
Will I need
to add ventilation to compensate for the tighter seal and
prevent condensation problems?
You will be
able to make a more informed choice, and enjoy the benefits of
both natural light and energy savings for years to come.
