What are the Best Double-Paned Windows?

What Are the Best Double-Paned Windows?

Choosing new double-paned windows for your home can be daunting, but we’re here to help you sift through the options to find your perfect fit.

There are several choices when it comes to double-paned windows. Sliding or casement windows? Argon or krypton gas-filled? Choosing the optimum thermal efficiency, usefulness, and appearance can be difficult with so many possibilities.

To make the process easier, here is everything you need to know about double-paned windows.

What Are Double-Paned Windows?

Double-paned windows are two pieces of glass separated by an inert gas space. These are the best windows for insulation because their dual structure reduces heat transfer between the interior and outside environments. 

To help with insulation and soundproofing properties, double-pane windows are often filled with an inert gas, typically argon or krypton. These gases help keep heat in during the winter and out during the summer.

Double-Pane Windows Vs. Single-Pane Windows

Unlike double-pane windows, only one sheet of glass makes up a single-pane window. Older homes typically have single-pane windows, particularly those with wooden frames.

Due to their poor energy efficiency, manufacturers rarely offer single-pane windows today. Switching from single to double-pane windows can save annual energy costs. This update will also add value to your home during a remodel.

Double-Paned Windows Vs. Triple-Paned Windows

As you likely inferred, a triple-pane window has three glass panels. Both double-paned and triple-paned options are durable windows.  Superior energy efficiency is provided by triple-pane windows, which is advantageous in extremely cold or hot climates; however, the added energy efficiency carries a 10–20% price premium.

The cost advantage of triple-pane windows over double-panes might not be realized for 30 years or more. As a result, a double-pane window is preferable in mild regions with warm weather.

Advantages of Double-Paned Windows

We’ve already touched on some of the benefits of double-paned windows. These are some of the most durable, energy-efficient windows available. 

Here are some other advantages to consider:

  • Window condensation – If you’ve ever lived in a home with single-pane windows, you’re probably already accustomed to the significant condensation that accumulates during winter. The varying temperatures inside and outside are to blame for this.

    Window condensation might be irritating, but it also indicates a far bigger problem. Single-pane windows allow chilly air to enter your home, which results in ineffective heat transmission and higher energy bills.
  • Tight seal – In comparison to single-paned windows, double-panes offer a considerably better seal around their edges, resulting in less air leakage through gaps and lowering heating expenses.

    The inner and outer sealed layers of a double-paned unit operate as a barrier against drafts and keep warm air inside your home. This seal is also built to withstand the tests of time, so you won’t need to worry about re-sealing year after year.
  • Noise reduction – Double-pane windows are an excellent option if you live in a busy neighborhood, near a highway, or wish to shut out outdoor sounds during your quietest hours.

    These durable windows effectively filter out noise far better than single-pane windows do. Finally, you’ll be able to wind down for bed in peace instead of hearing the whoosh and horns of passing cars.
  • Sunlight – Double-pane windows are the best windows if you want to keep out heat or sunlight to keep your house cool. Double-pane windows block more solar rays and keep a room much cooler than single-pane windows.

    The additional layer of gas between the two panes in double-glazed windows acts as insulation against both hot and cold temperatures entering your home through the windows.

Types of Gas

Glass manufacturers have the option of using air or one of three types of gas to fill the area between the double-glazed panes. Gas fills offer superior insulation over the air, despite being more expensive. Here are the various forms of gas that are used:

  • Argon – Argon is the most often used gas in double-pane windows. It is six times denser than air and hence, provides greater insulation.
  • Krypton – Krypton is another commonly used gas. Krypton is six times denser than argon but also more expensive.
  • Xenon – Xenon is the rarest and densest gas used as a window insulator. The expense of xenon is typically not worth the energy savings it delivers.

Types of Double-Paned Windows

If you’ve ever shopped around for windows, you probably know just how many options there are. Here are some selections to learn about to help you choose the best windows:

  • Double-hung – These double-paned windows, also called double casement or double hung, look like traditional single-pane windows. Still, they allow for ventilation from two separate sashes which slide up and down independently of each other.

    They are especially helpful for insulating homes– the interior side has a gas fill that helps to keep cold air out in winter months while absorbing heat during hot weather.
  • Sliding – These windows glide horizontally as opposed to swinging open like conventional double-hung versions, which allows for better ventilation. The drawback is that they only give access to a portion of the outside or inside world.
  • Dualpane vinyl windows – One of the most common types of double-pane windows is the dual-pane vinyl window. Depending on the model chosen, they come in double-hung, casement, or sliding variants and can be used for both vertical and horizontal applications.

    Low-E glass is used in these windows to increase insulation against energy loss. When you need noise reduction the most, such as during a storm or loud parties next door, dual-pane vinyl windows also provide excellent soundproofing qualities.
