Low-Emissivity or low-e units as they are more commonly referred to, were origianlly designed for
very cold climates. Emissivity is a measure of the ability of a surface to absorb and re-rediate energy, and for this reason
they were great in cold climates where heating was the dominating factor for development. By re-radiating energy, it reduced
the need to run a home's heater because the window would increase heat inside the home.
Today, units are coated to produce a high solar gain, moderate solar gain, or low solar gain
window, depending on the desired function of the window and the climate. The low solar gain units are the ones that most
resemble solar control window film. Although these units act in a similar fashion to film, they do not perform as well. The
best units will only block about sixty five percent of the solar energy, compared to the top performing films that
block as much as eighty eight percent. This is a difference of twenty three percent more solar energy that passes through
a low-e unit, reducing the amount of energy savings that can be provided had window film been installed.
Cost is another factor to consider when choosing to buy low-e units compared
to window film. The current price for a 4' x 4' insulated low-e unit to buy is $385-$425. This does not include
installation costs. The average price for window film installed on a window this size is $120-$160, depending on
the type of film chosen to buy. The film costs a third of what the window alone costs, and again, will out-perform the
low-e unit by more than twenty percent for heat blockage.
