Material, size, and style are the most influential cost factors for double-pane windows, but there are a few other things to consider, outlined below.
- Add-ons: Additional window features, such as an insect screen, low-emissivity (low-e) coating, tint, or coloring, increase the cost.
- Glass design: Double-pane glass comes in several designs. Though glazed is the most common and the least expensive, for an additional price you can choose from textured to mirrored.
- Glass type: Laminated glass is most common, but you can opt for tempered or argon gas-filled glass for an additional cost.
- Hardware: Window hardware isn’t always included in the price. Consider this expense when estimating the cost, especially if specialty hardware is required.
Energy Efficiency Upgrades
Replacing your windows with double-pane windows or choosing Energy Star-certified products can increase your potential energy savings. In fact, Energy Star states that upgrading from single-pane to Energy Star double-pane windows helps you save an average of $101–$583 annually.
Energy-efficient windows can also help keep your home’s temperature consistent, increasing its efficiency and comfort while lowering carbon emissions.
Number of Windows Installed
It’s more expensive to replace just a few windows than many at the same time. The labor for replacing one window costs an average of $150–$250 per window. Replacing 20 or more windows costs $80–$180 per window. So, if it’s within your budget, replacing many windows simultaneously is an excellent way to reduce your overall project cost.
Retrofit Replacement vs. New Construction Window
A retrofit replacement window involves less labor than a new construction window. A new construction window requires the installer to build framing and trim, essentially building out the window from scratch. It can involve modifying the structure of your home’s interior and exterior.
Retrofitting a replacement window means removing the old window and replacing it with a new one of the same size and style. It doesn’t usually require modifications. If any modification is required, it’s usually minimal to ensure a proper fit within the existing framing.
Most top-rated window companies manufacture and install double-pane windows. Some companies specialize in specific dual-pane window types, while others offer various options. Some companies will even create custom double-pane windows for your specific needs.
