How Much Does It Cost To Replace Double Pane Windows?

Double pane windows have become increasingly popular in recent years. They offer improved energy efficiency, sound insulation, UV protection, and durability. However, replacing your old, single pane windows with double panes will cost more. In this article, we’ll take a closer look at the costs involved and the factors that can affect the overall cost of replacing windows with double panes. On average, the cost to replace a double pane window ranges from $200 to $1,500 per window. The exact cost will depend on the size and type of window, materials used, and installation factors. In addition to the cost, we’ll also discuss the features and benefits of double pane windows, so you can make an informed decision about whether to upgrade your windows.

How Much Does It Cost To Replace Windows With Double Panes?

On average, you can expect replacing windows with double panes to cost about $450 each. This price is based on a traditional double-hung window with standard features. However, the total cost to replace a double pane window can vary. Factors that impact the total cost include the size and type of window, the materials used, and local labor costs.

Depending on those factors, the average cost to replace a double pane window ranges from $200 to $1,500 per window. A basic double-hung vinyl window can cost around $200 to $650, while double panes with low-E coating and gas fills can cost around $800 to $1,500.

It’s worth noting that the costs of installing new windows can be offset by lowering your energy bills and increasing the value of your home. You can also consider checking with the local government for any available rebate programs.

What Is a Double Pane Window?

A double pane window has two window panes instead the one. Also called dual-pane windows, the glass panes are separated by a small space called an air gap or spacer. This space is typically filled with air or an inert gas, such as argon or krypton, to improve your energy savings.

The purpose of the double pane construction is to improve the thermal insulation of the window, reducing the amount of heat that is transferred through the window. This can help to keep a building warmer in the winter and cooler in the summer, reducing your energy bills. In addition to saving on heating and cooling bills, these features also help reduce outside noise.

Double-glass panes are available on nearly all window types, but the costs will vary depending on the style and options. Some manufacturers also offer windows with triple or even quadruple window panes. However, they may not be available in all types and sizes.

What Factors Determine the Cost To Replace a Double Pane Window?

There are several factors that can affect the cost of double-pane windows:

  1. Type of window: The biggest cost factor is the type of window you choose. Single and double windows are typically the less expensive, while double pane bay, bow, and picture windows are the most expensive.
  2. Size and shape of the window: The size and shape of the window will affect the cost of the window itself, as well as the cost of installation. Larger windows or non-standard shapes will typically cost more.
  3. Materials: The type of materials used for the window frame, such as wood, vinyl, or aluminum, can affect the cost. Some materials, such as wood, may require more maintenance and may be more expensive in the long run.
  4. Energy-efficient options: While double pane glass is usually considered an energy-efficient option, you can also add other features. Low-E coatings, Argon or Krypton gas fill, and other advanced features can increase the cost of the window.
  5. Installation: The cost of installation can vary depending on the complexity of the project and whether you choose to hire a professional or do the work yourself.
  6. Additional features: If you want to add additional features to your windows, such as grills, screens, or custom shapes, it will add to the cost.

However, there is no added cost to upgrading to double panes from single-pane windows. Since the entire window is removed and replaced, the number of panes in the old window does not impact the price.

Average Cost by Frame Material

From vinyl to fiberglass or wood, the cost of replacing windows with double panes can vary depending on the frame material used. Here is a rough estimate of costs by material:

  • Vinyl: $200 to $650 per window
  • Fiberglass: $800 to $1,200 per window
  • Wood: $800 to $1,500 per window
  • Aluminum: $800 to $1,200 per window
  • Composite: $800 to $1,500 per window

When considering a frame material, it’s important to keep in mind the specific needs of your home and your budget. Also, consider the maintenance, durability, and energy efficiency of each frame material.

Average Costs by Window Size

Size is another important cost factor when it comes to double or dual pane windows. Here is how much you can expect to pay by window size:

  • Small windows (up to 24 inches wide and 36 inches high): $200 to $450 per window
  • Medium windows (24 inches to 48 inches wide and 36 inches to 72 inches high): $450 to $1000 per window
  • Large windows (over 48 inches wide and over 72 inches high): $1000 to $1500 per window

Again, these are only estimates. The exact costs will depend on other factors, like frame material and window style.

Average Cost by Window Style

The cost for double pane windows can vary depending on the window style. Here is a rough estimate of the average cost for double pane windows by style:

  • Double-hung windows: $200 to $800 per window
  • Casement windows: $500 to $1,200 per window
  • Awning windows: $500 to $1,200 per window
  • Sliding windows: $500 to $1,200 per window
  • Bay windows: $1,500 to $3,500 per window
  • Picture windows: $300 to $1,000 per window

In addition to the cost of the windows, you many need to factor in higher installation fees if you can changing from one style to another.

What Are the Advantages of Upgrading To Double Pane Windows?

There are several advantages to upgrading to double pane windows:

  • Energy efficiency: They have two panes of glass separated by a sealed space filled with air or an inert gas, such as argon or krypton. This creates an insulating barrier that helps to keep heat inside during the winter and outside during the summer, which can significantly reduce energy costs.
  • Sound insulation: The space between the glass panes will also help to reduce noise pollution from outside, making your home more peaceful and quiet.
  • UV protection: Many windows with double panes come with a low-E coating that reflects UV rays, which can help to protect your furniture, flooring, and artwork from fading due to sunlight.
  • Increased comfort: Their energy efficiency helps to maintain a consistent temperature inside your home, which can make your home more comfortable year-round.
  • Improved home value: Upgrading to double pane windows can improve the overall appearance of your home, which can increase your home’s value and appeal to potential buyers.
  • Durability: Windows with double panes are more durable than single pane windows and can last for many years with proper maintenance.

Disadvantages of Windows With Double Pane Glass

While windows with double pane glass offer many advantages, there are also some potential disadvantages to consider before upgrading:

  1. Cost: The price is one of the biggest factors, both in terms of the window itself and the cost of installation. That said, prices have come down dramatically over the last few decades. And the energy savings alone typically make up for the added window costs.
  2. Condensation: Although rare with quality windows, you can get condensation between the glass panes. While it’s usually not a problem, it can lead to mold or mildew eventually. Sometimes condensation is a sign you have a seal leak.
  3. Seal leaks: If you have gas fills between the panes, the seals can leak over time. While this does reduce the efficiency of the windows, most leaks are so slow the impact is extremely minor. Seal leaks can also lead to condensation forming between the panes.

Despite these disadvantages, the benefits usually make the added cost worth the upgrade. This is especially true if you live in areas with either very warm summers or very cold winters.
