What does U-Factor mean?


When you consider the insulation of your home, two terms are particularly relevant the R-Value and U-Value. Both are relevant to the thermal resistance of various elements of your home's structure. The R-Value is normally used for rating walls, roofs, and floors. The U-Factor, on the other hand, is used to determine the energy efficiency of windows. It's also good to note that a U-Factor of 0.25 equals an R-Value of 4.

The U-Factor or U-Value measures the rate at which heat is lost through a particular surface or substance. The lower the U-Factor, the better. Lower U-Factors reflect a greater level of insulation and a higher level of energy efficiency. This means that investing in a quality window will pay off in the long run since you'll spend that much less money keeping your home warm in winter and cool in summer.

When measuring the U-Factor of a window, there are several parts that need to be considered. It's not just about the window glass itself and the type of glazing but also the other parts of the window. Triple-pane windows will have a higher rating than double-pane ones, for obvious reasons. High-quality, specialized window coatings can also help improve the rating as well as the type of gas used to fill the spaces between the window panes.

The window frame and spacers also need to be inspected and put to the test as part of their U-Factor evaluation. For those who are in the market for energy efficient windows,  you should look for double-pane windows with a U-Factor of 0.30 or less, or a triple-pane window with a U-Factor of about 0.15.

Even if you don't use any kind of cooling system during the summer, you will still feel the benefits of quality windows. The right windows can make a great difference in the comfort level of your home. Instead of allowing the hot summer air to sneak in, they keep the heat outside where it belongs. While some might be tempted to air their home throughout a hot day in the middle of summer (in an effort to make the most of a nice breeze), it's best to air your home in the morning while the air is crisp and at its coolest. After a few minutes, or once the air in your home is well circulated, you should close all of your windows and keep them shut throughout the day. High U-Factor windows will then do their job and help maintain the lowest possible temperatures in your home.

During the winter, you want to keep your home comfortably warm without making your heating system work overtime. Leaky windows or windows with poor U-Factors will allow the heat inside your home to escape. The harder your heating system has to work, the more it will cost you on a daily, weekly, and monthly basis

LoĒ-180 glass also helps improve the efficiency of your windows by reflecting heat. In winter, the heat will be reflected back into your home whereas, in summer, it will be reflected away to keep your home cooler.

Alex and the team at north shield were amazing. Great customer service, along with a great team of installers. North shield replaced my 2 front living room windows in 1 day. They even took away my awning! Highly recommended

Jim gave us a great price, and I was also very happy with the installation team. Great workmanship, product, hey we’re friendly and clean. I am left feeling good about the company we chose to do our windows. I would certainly not hesitate in recommending them.

Andy and his crew installed the windows as agreed and were extremely pleasant. The cleanup was exceptional. They arrived on time. I would recommend North Shield to anyone looking for new windows. The service was incredible, The pricing was very good. The sales person Jim Scammel was very informative and knowledgeable. We had quotes from five (5) companies and feel good with our decision. The overall product was exceptional, but Andy was the STAR!!!! We did 17 windows and a door, so this was an important decision to our family.

We love our new windows. It was a challenging job for the guys as we are on the second floor of a condo but they were very professional and up to the task. Windows look great inside and out.

We had our windows installed last summer and absolutely love them - especially the large kitchen window. Our sales rep Jim S. was terrific and knowledgeable. The installers did a professional, skilled job of installing our windows. And the windows themselves are high quality, easy to open and easy to clean - as well as reasonably priced. We are very happy with our entire experience with this company and highly recommend them. Thank you!
