2With the colder winter months just around the
corner, you may be dreading your wintertime hydro
and energy bills to heat your home.

3Part of the reason people experience large
fluctuations in heating costs is often due to
heat loss through the windows on their home.

4Windows take up around 25 of the homes
exterior. Not only are they aesthetically
pleasing, but also allow sunlight to get inside
the home.

5However, what you may not realize, is one pane of
glass can experience 10 times more heat loss
compared to a comparable insulated wall of the
same size!

6To understand how heat loss works, lets do a
quick review of some basic scientific properties
about air. Heated or warm air is lighter and
moves to the upper areas of the room while cooled
or cold air is heavier and moves to towards the
ground.

7In the winter, as the warm air moves near the
windows, it is cooled and heat loss is occurs,
reducing the overall temperature in the home.
This results in your furnace running more often
to maintain your desire warmness level.

8TIP Condensation on windows in the winter means
heat loss is occurring.

9Another source of heat loss occurs when there are
small gaps around the windows. You may notice
this in your home if you feel cool air drafts
near the windows.

10This means the windows are not properly sealed
and are allowing cold air into the home.

11Stopping Heat LossTodays modern windows are
designed to stop heat loss. Most designs are
double-paned, which means there are two layers of
glass with a gap for air in between each pane.

12This creates a type of air insulation to keep the
warm air inside your home where it belongs.
Well-fitted, modern windows also address problems
with air gaps and cold air drafts.

13Replacement, energy efficient and Energy Star
rated windows are highly recommended for homes
with windows that are more than ten years old.

14There have been several advances over the past
decade and these work much better to stop heat
loss.

15In addition, you want to make sure replacement
windows are rated at least with an Energy Star
Rating for Zone 2 due to the cold Ottawa winters.

16Using Zone 1 windows will not be as effective at
stopping heat loss. In some cases, like for
windows that never get any direct sunlight a Zone
3 rating may be more appropriate for your home.

17If you are not looking forward to another winter
of costly heating bills, now is the time to
consider getting Energy Star approved windows
installed on your Ottawa home.
