The insulation value of any window
depends on air films adjacent to the glass
surface and, any air spaces enclosed
between two or more layers of glass. The
thickness of the glass has little bearing on
the heat transfer through the window.
The first step is,to make sure the windows
are properly sealed- This means caulking
around frames and trim, sealing individual
panes of glass, and weatherstripping all
movable seams.
Once this is done, the trick is to install an
extra layer of glazing, thus providing an in-
sulating air space between the inner and

From the inside, the most inexpensive op-

must be airtight so that condensation will

and can be installed inside for protection
and convenience. However, factory sealed

that face south, should be- shuttered only
from the outside.

there are many types of insulation
„ There are many types of insulation
materials. Each has specific,characteristics
and should be used only asdirected. The ac-
companying list shows the most common
types and the recommended applications
for each.
The RSI(R) value indicates the relative
resistance to heat flow of each product. The
higher the RSI(R) value, the better the
material insulates. RSI is metric and R is
imperial measurement.
A suitable air -vapour barrier, such as 6
mil (0.15 mm) polyethylene sheeting, must
be used with most insulation. It must be ap-
plied to the warm side of the insulated sur-
face. Air leaks should be sealed to ensure
that the air -vapour barrier works effective-
ly.
If you're adding insulation, upgrading the
quality of the air -vapour barrier should be
included as part of the job. If there isn't one
in place, every effort should be made to add
one. Where this can't be done without major
disruption and expense, a quality air -vapour
barrier paint will increase the resistance of
the walls to moisture flow.
When you are choosing insulation,- you
should ask yourself these questions:
• Does the product exhibit good` heat reten-
tion?
• Has it been evaluated under a CMI
materials evaluation report?
• Will the material resist high temperatures
or fire?
• Will it withstand highimoisture levels?
• Will it resist air infiltration and exfiltra-
tion?
