Double Pane vs Triple Pane Windows

When it comes to selecting windows for your home, one important decision is whether to choose double-pane or triple-pane windows. Both options have their advantages and considerations, and understanding the differences between them can help you make an informed decision. In this article, we will explore the features, benefits, and considerations of double-pane and triple-pane windows, helping you determine the best choice for your specific needs.

Double Pane Windows

Double Pane Windows

Double pane windows consist of two glass panes separated by a layer of insulating gas, typically argon or krypton. They have become a popular choice for homeowners due to their energy efficiency and affordability. Here are some key features and benefits of double pane windows:

  • Energy Efficiency: The insulating gas between the panes helps to reduce heat transfer, improving the overall energy efficiency of your home. This can lead to reduced energy consumption and lower heating and cooling costs.
  • Noise Reduction: Double pane windows provide better sound insulation compared to single pane windows, reducing noise from outside sources and creating a quieter indoor environment.
  • Condensation Control: The insulating gas and sealed design of double pane windows help prevent condensation buildup on the inner surface of the glass, reducing the risk of moisture-related issues such as mold and mildew.
  • Cost-Effective: Double pane windows are generally more affordable compared to triple pane windows, making them a budget-friendly option for homeowners.

However, there are a few considerations to keep in mind when choosing double pane windows:

  • Insulation: While double pane windows offer significant energy savings, they are not as efficient as triple pane windows in terms of insulation. If you live in an extremely cold climate, you may want to consider triple pane windows for enhanced insulation.
  • Soundproofing: While double pane windows provide noise reduction benefits, they may not be as effective as triple pane windows in blocking out loud noises, especially if you live in a noisy neighborhood or near busy roads.

Triple Pane Windows

Triple Pane Windows

Triple pane windows, as the name suggests, consist of three glass panes with two insulating gas layers. They offer enhanced energy efficiency and soundproofing compared to double pane windows. Here are some key features and benefits of triple pane windows:

  • Superior Energy Efficiency: The additional glass pane and insulating gas layer in triple pane windows provide enhanced thermal insulation, reducing heat transfer and improving energy efficiency. This can result in further savings on heating and cooling costs.
  • Exceptional Sound Insulation: Triple pane windows offer superior soundproofing properties, making them an ideal choice for homes located in noisy areas or near airports, highways, or busy streets.
  • Increased Comfort: The extra insulation provided by triple pane windows helps maintain a more consistent indoor temperature, reducing drafts and cold spots near windows and enhancing overall comfort.
  • Condensation Control: Triple pane windows are highly effective in preventing condensation buildup, reducing the risk of moisture-related issues and maintaining a healthier indoor environment.

While triple pane windows offer numerous benefits, there are a few considerations to keep in mind:

  • Cost: Triple pane windows tend to be more expensive than double pane windows due to the additional materials and manufacturing processes involved. Consider your budget and energy savings potential when deciding if the investment is worth it for your specific needs.
  • Weight: Triple pane windows are heavier than double pane windows, which may require additional structural reinforcement or adjustments during installation.

How much do triple-pane windows cost in Calgary?

The cost of triple-pane windows in Calgary can vary depending on several factors such as the size of the windows, the quality of the materials, and the complexity of the installation. On average, triple-pane windows in Calgary can range from $800 to $1,500 per window, including installation. However, it’s important to note that these prices are estimates and can vary based on the specific requirements of your project and the window supplier or contractor you choose. It’s recommended to obtain quotes from multiple suppliers or contractors in Calgary to get a more accurate cost estimate for your triple-pane windows.

Should You replace Double to Triple Pane Windows in your house?

Deciding whether to replace your double-pane windows in Calgary with triple-pane windows depends on several factors. Triple-pane windows offer improved energy efficiency and soundproofing compared to double-pane windows. If you live in a region with extreme climates or noisy surroundings, upgrading to triple-pane windows can provide significant benefits. However, the decision should consider your specific needs, budget, and the condition of your existing windows. While triple-pane windows offer superior performance, the cost of replacement might not always justify the energy savings. It’s recommended to consult with a professional window installer who can assess your current windows and provide personalized advice based on your circumstances.

What are glazed windows?

Glazed windows refer to windows that have a glass pane or multiple glass panes sealed within a frame. The term “glazing” refers to the process of fitting glass into windows. Glazed windows are commonly used in residential and commercial buildings and provide several benefits. They enhance natural light transmission, improve insulation, and reduce heat transfer, thus increasing energy efficiency. Glazed windows can be single-glazed, double-glazed, or even triple-glazed, depending on the number of glass panes used. The space between the panes may be filled with air or inert gases to enhance insulation properties. Glazed windows also come in various types, such as casement, sliding, or fixed, offering versatility in design and functionality. Overall, glazed windows are a popular choice due to their aesthetic appeal, thermal performance, and noise reduction capabilities.


Both double-pane and triple-pane windows have their advantages and considerations. The choice between them depends on factors such as your budget, energy efficiency goals, noise reduction needs, and local climate conditions. Consulting with a reputable window professional can help you evaluate these factors and make an informed decision. Ultimately, investing in high-quality windows, regardless of the pane configuration
