Replacing the windows is a significant investment, and when you’re investing so much in your home, you want to make sure you understand all the options and are making the smartest choices for your situation. The average cost of home window replacement can be quite high, and it can be overwhelming to make all the right decisions. Choosing the window type is important when considering energy efficiency and long-term investment in your home.

Single Pane Windows

Single paned windows are commonly found on homes built prior to 1980 that haven’t had any window upgrades yet. A single pane window consists of just that – a single pane of glass. There is no insulation, making them a less efficient choice. They also do little to block out any noise. Single pane windows are usually chosen entirely by those on tight budgets. If you’re located in an area with consistent mild temperatures in a quiet neighborhood, y

ou may be ok with single pane windows. But when it comes to insulation, you won’t get much at all.

Double Pane Windows

Double pane windows are constructed with two panes of glass, separated with a space filled with air in between. This air space is what insulates your home and makes these windows significantly more energy efficient than single pane windows. If you make the switch from single pane to double pane windows, you will notice the difference in sound and temperature immediately. Double pane windows are also more durable, more secure, and, as a long-term investment, a very smart choice.

The Average Cost of Home Window Replacement

Single and double pane windows have big differences in energy efficiency, strength, and cost. Single pane windows can be installed for as a little as $100-200 for each window, including installation. Double pane windows often run between $400-$600 a window, which is a significant difference. However, when factoring energy savings, security, durability, and comfort, double pane windows may be the smarter long-term investment.

In almost every case, all windows are replaced at once, so given the average cost of home window replacement, most homeowners are looking at a big financial investment. A good window is about more than just the glass. The frame and seal are just as important in making a quality window installation.
