Glass panes are the main elements of any window, therefore it is most important for them to be of the highest quality. Harsh prairie climates usually require a minimum of 2 panes for adequate thermo-insulation. We, at Ecoline Windows, go as far as making 3-pane units, especially beneficial for areas with prolonged winter where temperatures remain lower for longer.
In addition, windows get a large part of their energy efficiency from low-emissive (LoE) coatings on interior panes of glass. Gases like Argon and Krypton are injected into the sealed glass unit to further lower the amount of heat transferred through the window.
Triple pane windows feature an additional pane that is located between the two exterior panes. This means you get the additional benefit of an extra layer of Argon or Krypton Gas between the panes, which leads to better insulation. Triple pane windows are also set in sturdier, higher quality frames and are equipped with stronger hardware, making them more durable and better performing when compared to double-pane units.
For ENERGY STAR®, there are three climate zones in Canada (1, 2, 3), based on an average annual temperature indicator called a Heating Degree Day (HDD). Zone 1 is the mildest and Zone 3 is the coldest. Colder areas require windows that are more energy efficient.
LoE Coated Glass
Approximately 75% of the window area is glass. Although windows provide beautiful views and wonderful natural light, they can also be responsible for the majority of the annual heating costs for a home, through heat loss. It is important that new windows effectively retain heat inside, while keeping extreme hot and cold weather outside.
Three most important values to pay attention to are U-value, R-value and Solar Heat Gain Coefficient (SHGC). The lower the U-value (higher R-value) the better windows at keeping out the heat and cold. The combination of three layers of the coating has the lowest U-value number. It offers high insulating properties, blocks heat and UV rays. These glasses appear to be slightly darker than the clear glasses. To allow more solar heat to enter the home choose the combination of glasses with higher U-value.
Think of LoE coating as invisible insulation that helps to provide a shield:
Unique combinations offer different protective properties allowing the sun heat to get through or block it completely.
In the winter, LoE coated glass helps keep your home warm and cozy by blocking heat loss through windows while allowing the sun’s heat inside.
In the warmer weather, LoE coating blocks the sun’s harmful UV rays, protecting the interior of your home and keeping your furniture from fading. At the same time allowing in more visible sunlight.
Ecoline Windows uses high-performance Cardinal Endur insulating glass spacers for optimum durability and efficiency. Spacers are made from warmer edge stainless steel to improve temperature control and condensation resistance.
LoE coated glass is simply the best way to help minimize energy costs and maintain comfortable temperatures inside your home all year round.
LoE glass retains more interior heat than ordinary glass, helping to maintain a comfortable temperature.
Cooler in the summer
LoE glass filters out harmful UV rays and reduces solar heat gain.
Argon and Krypton Gas
Triple pane technology is designed to reduce the window’s heat conductivity and stop the cold from getting inside the house. To achieve this, Argon or Krypton Gases are utilized to fill the space between the panes. Both gases conduct up to 50% less heat than air, and when coupled with triple pane construction and Endur IG spacers you get added protection against heat loss, condensation and cold weather. Less heat loss translates directly into more energy cost savings for you.
