Triple Pane Window Cost Breakdown

Your windows are an important component of every room. They let natural light into your home, enable you to enjoy a cool breeze when the weather’s nice, and allow your cat to bird-watch on demand.
The main factors that influence the cost of triple pane windows are materials and labor.
Number of Windows
The number of windows you'll need will significantly impact your total costs. For example, a home with 20 windows will cost $6,000 to $54,800 for materials and an additional $2,000 to $6,000 for labor.
Materials
Triple pane windows typically cost $300 to $2,740 per window. Wood-framed windows are usually more expensive than windows with vinyl or aluminum frames. Larger size windows also tend to be more expensive.
Window Type
Large windows will naturally cost more than average-sized windows. Triple pane windows need extra care during the assembly process, and, with increased size, they also require more materials. The same is true of uniquely-shaped triple pane windows. Bay windows and large picture windows can cost up to three times more than average windows.
Labor
Labor costs for installing triple pane windows range from $100 to $800. Overall labor costs will depend on how many windows you’re installing and the size of your windows. Labor costs also vary depending on whether you’re installing the windows on the ground floor or an upper story. It can take up to an hour longer per window for upper-level installation.
Spacer
The term "spacer" refers to the gas or material between multiple panes of glass. A spacer helps aid in insulation and noise reduction. A higher quality spacer gas or material will affect the overall price per window.
First, Second, or Third Story
When creating a budget for your project, you'll need to consider the location of your windows. Windows on second stories and higher require more safety precautions and care. Usually, this results in additional time and thus an increased labor cost. You can safely assume that most upper-level windows will take at least an extra hour to install.
