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.

11 new windows, 3 entry doors, 2 patio doors, phenomenal look and installation. Hydro bill dropped significantly even with the increase in rates. Team was fast and efficient. Broke one window and had it ordered and installed within a few days! Will use these guys for all my future window and door needs! A++++ experience.

Love our new windows and doors. We had all our windows replaced on the main floor, side door and front door, as well as the storm doors. The installation team was great. They removed the existing awning and were really great at cleaning up after the work. There were a couple of issues after the install, but the after sales service team of Alex and Walter were able to resolve it promptly. Great advice from Walter about keeping the humidity inside the house to maintain the windows, and also how to operate them properly. And thanks very much Alex and team for buying the doorbell and installing it for us, as well as fixing the bottom part of the door frames to cover holes on the flooring. Appreciate all your hard work and for going the extra mile. Will definitely recommend your company to friends, neighbors and family.

Jim came by to give us a quote on a window and door he was very friendly until we sat down and decided what we wanted in are window and door. He was saying that are home was not are forever home. Insulted our house how does he know this is not our forever home very rude. Then he ask us the other company that came by we told him and the quote that they gave us, and he started being argumentative saying that it cant be its too low they cant be cheaper then me. And also pushing us to get a storm door which we said we just want a door then he said if we go to home depot there doors are not good. Sorry but dont want someone that insults are home and is rude instilling are window and door.

NorthShield did an excellent job with our house. They were the lowest price our of 4 companies I contacted for quotes. The windows look beautiful, and the molding is very well done. The installation was very quick, they replaced all of the windows in our house in about 4 hours. They cleaned up everything completely afterwards inside and outside, you can't even tell they were here! Very professional, very high quality installation, materials and work. I would highkly recommend them.

Firstly, I received a quote from Northshield in September - When I called to go forward with the windows it was early November and the price had jumped up close to $1,000. We had many quotes for windows, Northshield was not the cheapest but I went with them due to good reviews. They seem to have an issue with customer service as my windows were ready for over a month with no installation date in sight. I called and left several messages trying to get an idea of installation date before anyone called me back. The only reason I am giving more than 1 star is because the final product and installation team was good, aside from the slight crack in one of my frames and the mess left behind in my yard including many cigarette butts. In the future I will be going with a different company and would not recommend them.
