Energy-Efficient
Windows
|
When purchasing a new
home, homeowners want their home to be correct in
every detail while costing as little as possible.
 However,
savings to a homeowner can also occur after the home
is purchased, by using energy-efficient windows.
Energy-efficient windows have a tremendous
impact on energy performance (and costs) of heating
and cooling a home, as well as seasonal comfort
level experienced by the homes occupants.
While energy-efficient windows will cost more
initially, they often return their additional cost
investment through substantial savings to the
home-owner on monthly energy bills.
Windows
provide less resistance to heat flow than walls,
ceilings, and floors of your home.
Even when windows comprise a small area of a
home, they are the area of greatest heat loss and
gain, and air leakage.
Windows can account for as much as 25-30% of
the heat loss in a home.
This increases energy use and costs, and
decreases your comfort.
Therefore, with the installation of Thermalizer
energy-efficient windows you can cut back on
such expenses.
A
windows ability to resist heat flow, its insulating
value, is defined by its R-Value or U-factor.
The U-factor is the reciprocal of the R-Value
(R=1/U). The
larger the U-factor the greater the heat flow
through the window.
Glass by itself is an extremely poor
insulator. A
single-pane window of clear glass is the least
effective. But,
by upgrading to a double-pane, double-strength
window with Low-E2 Glass this becomes a very
efficient window to have in your home.
To
help alleviate confusion associated with window
energy performance and ratings, the National
Fenestration Rating Council (NFRC) has developed a
window rating system based on whole window
performance. The
NFRC rating accurately accounts for all product
components and presents window information in a
concise and easy to understand format.
The
NFRC energy ratings take into account the window’s
resistance to heat flow (U-factor), the amount of
heat admitted as radiant energy (solar heat gain
coefficient, SHGC), and the amount of visible
transmittance (VT).
