The Benefits of Triple Pane Glass Windows

Deciding the type of glazing you want for your windows extends beyond the knowledge that double glazing has two panes of glass, and triple glazing has three. There are many factors to consider, such as cost, energy efficiency, and durability, in order to conclude whether triple pane windows are the right investment for your home or office space.


What are triple pane glass windows?


Due to harsh climates, double pane windows are required as a standard for all residential applications in Canada. Double pane windows can reduce heat loss by up to 50%, so your energy costs stay low. Triple pane windows are much heavier by comparison and require a strong frame material that will be durable enough to withstand the weight. Fiberglass frames are recommended, as they are able to withstand heavy loads without warping or sagging over time.

The weight difference between a double and triple pane window simultaneously reflects the difference in performance. The Solar Heat Gain Coefficient (SHGC) measures how well a window blocks the transmission of solar radiation, while thermal transmittance (U-values) indicate the rate of heat transfer and how well a window insulates. Both measurements analyze energy performance, with lower values indicating less solar heat transmission and therefore better insulation. When comparing such factors as the SHGC or U-values, there is an improvement of approximately 20-30% in a triple pane window’s energy ratings over those of a double pane window. U-factor values generally range from 0.25 to 1.25 and 0.19 to 0.26 for double pane and triple pane windows, respectively, indicating the superior performance and thickness of triple glazing. 




Are triple pane glass windows a good investment?


The low U-factor provided by triple pane windows is simultaneously useful during cold Winnipeg winters and humid summers. In fact, windows with low SHGC values help reduce summer cooling demand – skilled technicians, such as the experts at NorthShield, recommend looking for values of 0.25 or less if you have significant air conditioning costs. Similarly, the larger your heating bill, the more important a low U-factor becomes to offset heat loss during the notoriously frosty Winnipeg winters. Standard windows might prove insufficient at transmitting heat, as those with lower U-factors allow for higher interior temperatures and thus greater comfort.


Triple pane windows can also include features such as low-E coatings, gas fills, and insulated spacers and frames to reduce solar radiation, or heat escaping through the glass. Low-emissivity (low-E) glass windows have a thin, transparent coating that reflects heat. It was created to minimize the transmission of infrared and ultraviolet light, without reducing the amount of light entering the space. Because of this property, low-E coatings can significantly reduce solar heat transmission with only a minimal loss in light and view.

Meanwhile, triple pane windows use the same argon or krypton gases found between the panes in double glazed windows, except the gas is injected in both air spaces. Both argon and krypton gases conduct up to 50% less heat than air and further reinforcement onto an additional pane of glass improves the window energy rating by 20%. The low-E film can also be added on the non-exposed surfaces of the glass, thus significantly increasing not only the energy efficiency of triple glazed window but also their ability to reduce the transmission of outdoor noise.

Furthermore, the insulated spacers and frames found in triple pane windows result in their superiority at reducing condensation over standard windows. When the surface temperature of an interior window pane is lower than the given relative humidity of airborne water vapour, condensation will occur on the glass. Therefore, a higher surface temperature coincides with higher insulation values, which lowers the possibility of vapor to condense or frost on the glass.


Invest in the future of your home or office


Triple pane windows achieve higher standards in both solar and sound transmission, and reduce the likelihood of experiencing condensation or costly energy bills. Triple glazed windows offer greater opportunities for energy efficient upgrades and achieve higher performance values in virtually every metric over double pane windows. Reputable companies such as NorthShield proudly manufacture the latest in triple-glass and low-E technology in Canada, so you can be confident their products were especially designed and built to withstand the versatile extremes of Winnipeg climates.

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.
