If you have noticed it is time to replace your windows, you may have started to think about which replacement windows are right for your home. Replacing your windows in your home is not an easy decision – you have to consider the buying price and cost of installation, energy efficiency, lighting, aesthetics and much more. And, while most people spend time thinking about whether they want vinyl, fiberglass or wood replacement windows, there is another perhaps more vital consideration: choosing between double pane glass and triple pane glass. At WoW, we often get asked the difference between double and triple pane windows, which is why we will break down what you need to know about window panes so you can make an informed decision about what is right for your home.
Sound and Noise Pollution
When it comes to sound and reducing noise pollution, many home improvement contractors will tout triple pane windows as the ultimate window. However, the truth is the difference in sound and noise prevention between double and triple pane windows is negligible. In reality, the biggest impact on sound transmission comes via the type of glass you choose, not the number of panes the window has. Which type of glass is best at reducing noise? Laminated glass has been shown to be one of the most effective ways to limit noise.
Window Weight and Functionality
Triple pane windows are inherently going to be heavier than double pane windows due to the additional pane of glass. While this coupled with more robust framing makes the window heavier, it should not be a deciding factor on which windows to choose. The counterbalance mechanism that supports triple pane windows holds the majority of the weight, and if it is properly installed, the additional weight of a triple pane window should not be any more noticeable than its double pane counterpart. And if you are curious about functionality, a heavier triple pane window works in the exact same way as a double pane window.
Energy Efficiency
Energy efficiency is where the main difference between double and triple pane windows is stark. Triple pane windows are exceptionally better in terms of energy efficiency, offering superior performance in thermal resistance. The additional pane in triple pane windows offers an extra space that is filled with a special gas that reduces heat and cold transfer. The more energy efficient your window, the better long term impact on the heating and cooling costs of your home.
Price
Generally speaking, triple pane windows will cost more than double pane windows. However, as mentioned before, the long term heating and cooling costs of your home make triple pane windows a sound investment. Most companies will vary on cost between double and triple pane windows. At WoW for example, labor and install costs are fixed for both double and triple pane windows, meaning we only charge for the additional materials in a triple pane window.
Finding the Right Replacement Window Contractor
Finding the right contractor can definitely make the whole process of replacing your windows that much simpler and less stressful. You want to ensure your contractor is familiar with installing triple pane windows. Triple pane units are significantly heavier than double pane and may require small changes in the installation application. You do not want to spend good money on the best product and then have a substandard install ruin the project. Remember: even the most energy efficient window on the planet - if installed poorly - will not perform as intended.
When trying to find the right contractor, never hire one without asking for a few references. You can start with websites like Angie’s List, Yelp, or Houzz if you want to find information about how contractors have worked on past projects and read reviews from previous customers. Finally, make sure your contractor is licensed. Before you hire them, it is important you ask to see their license and proof of insurance.
