What is a U Factor?

 The U Factor is probably the most important score for a window because it reflects what window company's strive to do; create heat efficient windows. The U factor is scored by measuring the amount of heat loss that occurs through the window, which is very important to people in colder climates. Most windows have U factor ratings between 0.2 and 1.3, with the numbers on the lower end of the scale being the best. For example, windows that have a U factor of 1.3 are usually old metal casement windows, while some of the most efficient thermal windows that have triple panes of Low­ E glass have U factors of 0.25. New single pane windows may be able to get a U Factor of 1.0, and a dual pane window with low E glass will usually score significantly better at around 0.4.


What is the solar heat coefficient?

This is basically like the U Factor, but instead of measuring the heat loss, it measures the amount of heat coming in through the window. This is about as important as the U Factor if you live in hotter climates. Ratings of solar heat gain coefficient range from between 0 and 1 with lower numbers being more efficient.


Should I consider the condensation resistance of windows?

If you live in humid climates, it's very important to consider this rating. Problems with condensation, however, can occur in any home that has a well insulated house with poor ventilation. The higher these scores are, the more resistant the window is to condensation.


What does visible transmittance mean?

Visible transmittance is the amount of visible light that can pass through the window. Note that this only includes visible light, so it does not affect efficiency as much as the other scores. This is mostly a personal preference on how much light you want entering your rooms, where higher scores allow more light to pass through the window.
