Before we get into the differences between double pane and triple pane windows, let’s identify what a double pane window is, and why it’s different and better than a single pane window. A double pane window is exactly what it sounds like — a window with two panes of glass. However, an energy efficient double pane window has a layer of argon gas between the two panes, which acts as a buffer to the elements. This is different from a classic single pane window, in that single pane windows have no gap to fill with argon, and just provide basic single glass pane separation between the inside and the outside of your home.
Why buy triple pane?
Some people tend to think of triple pane windows as a luxury, and in some regards, they may be correct. Triple pane windows are certainly not the cheapest type of window on the market, but they do truly outperform double pane windows in providing warmth and comfort inside your home.
For instance, if you had a triple pane window installed a few feet away from a double pane window and stood next to each of them in the dead of winter, you will surely notice that the triple pane window lets much less cold through compared to the double pane window. Also, triple pane windows are less prone to condensation buildup than double pane windows, which add to the lifespan of the windows and frames.
What is R-Value?
R-Value is a method of measuring efficiency – the higher the R-Value, the better the window resists heat. Normal R-Values fall between 0.9 and 3.0. The number of glass layers used, quality installation by contractors trained to identify leaks, the size of the space holding the argon gas, and how well the frame resists conducting heat or cold all play a part in a window’s R-Value.
This means that any consumer who wants to improve the energy efficiency of their home should pay close attention to the R-Value of the windows they are considering. The higher the R-Value, the better the energy savings. The better the energy savings, the higher the return on investment will be in the long run.
What do experts recommend?
Well, experts recommend getting the most energy efficient windows you can afford. Ideally, this would be a no-brainer for choosing triple pane windows, due to their increased efficiency and return on investment.
