When purchasing a new
home, homeowners want their home to be correct in
every detail while costing as little as possible.
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.
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
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
larger the U-factor the greater the heat flow
through the window.

efficient window to have in your home.
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
NFRC rating accurately accounts for all product
components and presents window information in a
concise and easy to understand format.
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
