When shopping
for windows there are some terms you need to know
so that you can compare performance and quality
among the various brands. We'll list the basic
terms for you here:
U-Factor
- U-Factor measures overall energy efficiency.
It tells you the rate at which Heat flows through
the entire window or door frame. The lower the
U-factor, the more energy-efficient the window
or door.
R-Value - R-Value measures
the transfer of temperature through an object.
The higher the number the more energy efficient
the window, door or object is.
Solar
Heat Gain - SHGC measures how well the window
blocks heat from the sun. The lower the SHGC,
the less solar heat the window lets in.
A few other
things you need to consider when looking at windows
are related to the construction of the frame.
How thick is the vinyl making up the frame. The
frame on a vinyl window must be welded for strength
so check to see if the corners are welded together
when looking at samples. Vinyl windows also need
to have multiple hollow chambers between the frames
for optimal thermal performance.
In Iowa
the ideal window should have a U-Value of .30
or less according to Energy Star because we are
in the northern zone. Find out more by visiting
The
Energy Star Website!
We
have an entire line of windows manufactured here
in the Midwest. Our triple glazed windows have
a U-Value of .22.
