Triple pane windows have been gaining popularity among homeowners who are looking for energy-efficient windows. Compared to double pane windows, triple pane windows offer more benefits such as better insulation, noise reduction, and improved security. However, like any other products, triple pane windows have their disadvantages. In this article, we'll explore the downsides of triple pane windows.

1. High Cost

Triple pane windows are more expensive than double pane windows. The extra pane adds to the manufacturing, installation, and transportation costs. While triple pane windows can significantly reduce energy costs, the initial investment may be too high for some homeowners. If you're on a tight budget, you may want to consider alternatives such as double pane windows or improving the insulation in your home.

2. Weight

Triple pane windows are heavier than double pane windows. This can make installation more difficult and increase the risk of breakage during transportation. The added weight can also put more strain on the window frames and hinges, leading to more frequent maintenance and repairs. If you're replacing your windows, you may need to reinforce the frames to support the additional weight.

3. Reduced Sunlight

One of the benefits of triple pane windows is their ability to block harmful UV rays. While this is great for preventing sun damage to your furniture and flooring, it can also reduce the amount of natural light that enters your home. If you enjoy a lot of natural light, you may want to consider tinted or low-E glass options instead of triple pane windows.

4. Condensation

Triple pane windows are better at insulating your home, but they also trap more moisture. This can lead to condensation forming on the windows, which can cause mold and mildew growth and damage to your window frames. To prevent this, you'll need to make sure your home is well-ventilated and use a dehumidifier if necessary.

5. Limited Availability

While triple pane windows are becoming more popular, they may not be readily available in your area. Some suppliers may only offer double pane windows, while others may have limited options for triple pane windows. If you're set on installing triple pane windows, you may need to shop around or consider ordering from a manufacturer that specializes in energy-efficient windows.


While triple pane windows offer many benefits, they may not be the right choice for everyone. The higher cost and weight may be too much for some homeowners, while others may prefer more natural light in their homes. If you're considering triple pane windows, make sure you weigh the pros and cons carefully to make an informed decision. Remember to compare different suppliers and manufacturers to find the best price and quality for your needs.
