What is a U-Factor for Vinyl Windows?
Vinyl windows protect us from harmful elements of nature. When evaluating energy efficient windows, we have to examine what is known as the u-factor.
High performing double window pane set-ups will have a U-factor of 0.30 or lower. In fact, triple-pane windows go down to as low as 0.15, which speaks a lot for their energy efficiency. Some window manufacturers have begun to add coatings that emit lower as well as use gas in spaces to decrease the U-factor level.
A few people also take into consideration the center of glass factor — this refers to the rating of the glazing on the glass alone. Though not common, it is sometimes asked for as well.
