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.

Northshield replaced 9 windows in our house. Our only complaint would be that the colour doesn't really match the sample we were shown. The woman we first encountered in the showroom was pleasant and helpful. There are only so many things she could tell us in the showroom but it was enough to convince us to book an appointment with a salesman. Walter, the fellow who came to our house, wasn't really a salesman at all and yet he knew exactly what he was doing. Answered all of our questions, clearly knew his business inside and out, was patient with us, made some really helpful suggestions, and just generally made us feel confident and comfortable. Next came Vladimir. He came to do the final measurements and to verify the details of each window. Another very very knowledgeable guy. Clearly an expert in his field and yet friendly and patient with us. The team of men who came to do the install were all very much polite and professional. Their workmanship is first rate. In the end, what I know is this, the new windows are in, the drafts and rattles from the old ones are gone, the price was fine, the quality is A1, and every single individual along our journey was a genuine pleasure to work with.

We chose Northshield because of the rave reviews on Google, but unfortunately the experience was a disappointment. The sales guy was nice enough, but like most suppliers in their industry, installation came 6 weeks past their original estimate, which was fine since we were not in a big rush, although we had to delay the painting of our kitchen because of it. The two big issues were: 1. To install our new patio doors, the opening had to be widened, which our sales guy mentioned, and which was fine to us. The problem came when the installers were on site and insisted that they did not need to replace the header. I know nothing about construction but luckily my colleagues told me to make sure that they install a new header because they were widening the doorway. Luckily I was home and I persisted that they install a new header, and after a while they finally realized that they needed to do it as well. They went off to the store to get the wood and the drywall and finished the job, which looked fine. 2. Only a few months later big cracks appeared along the new header. I called Northshield only to be told by Alex that my painter should've known that the patchwork on the header was very minimal and that "any professional painter should've known to make sure the drywall was ready to be painted." So they refused to do anything about it. I guess I should've said back to him "any professional installer should've known you need a new header when you widen a doorway!" So now I have a wall that I will need to re-patch and re-paint all over again. If you decide to use Northshield, please do your own research and make sure that you oversee their work, because they will never take responsibility for it, or admit that they didn't know what the heck they were doing.

Professional, clean, good customer service. Fast and efficient. No surprises or hidden costs, did not try to upsell me and worked within my budget. Very happy with the finished product and will continue to use in the future for replacing my remaining windows.

We had 4 windows installed by this company. The windows were installed in no time at all, and the guys were very professional and efficient. Love the windows and would recommend this company to anyone.
