Tips for Choosing the Optimal Glazing for New Replacement Windows November 19, 2014 You have finally decided to replace your existing windows in your home. It’s an important decision to make and when you sit down and really think about it, it’s going to be a significant investment. Any time that you invest in something, you should expect or hope for a return on it. That doesn’t mean it always happens and when you are talking about replacement windows, if you end up choosing the cheapest possible kind that you can find, you shouldn’t be expecting to gain much out of that investment. Assuming that you’re focused on quality windows for your Toronto home, you will likely be faced with numerous options. One of those options is choosing between double and triple glazed windows. This essentially refers to the panes of glass that the window contains. Double glazed windows have two panes of glass that are separated by a section of air, usually between 1 to 2 centimeters apart and the air between them is vacuumed out and sealed. You can also choose to have the gap between the panes of glass sealed with argon or krypton gas (more energy efficient). Triple glazing is essentially the same except that you will have three panes of glass instead of two. This means that there will be two spaces between the glass that need to be vacuum sealed. Triple glazing will offer more energy efficiency, which means that it will protect against the cold air during the winter much more effectively, but it is more expensive and much heavier than double glazed windows. If your window frame isn’t going to support the weight of triple glazed windows without significant renovations, then this option would be unreasonable. Speak to a window professional at Platinum Windows and Doors to determine whether you would benefit from triple or double glazed windows for your Toronto home.
