The benefits of double-pane windows far outweigh those of single-pane versions. Deciding between the two usually comes down to how much they cost. 

Single-panes are, of course, cheaper than double-panes, but this doesn't necessarily make them more cost-effective. 

Understanding why double-pane versions are best is key to making a wise selection. 

How Much of A Difference Do Double-Pane Windows Make?

There are many advantages to double-pane windows over single-pane versions. 

They enhance energy efficiency, 

  • decrease noise
  • boost security 
  • block more UV rays
  • raise property values. 

These windows come with a high ROI (return on investment) and are vital to improving a home's ventilation. 

What Is a Double-Paned Window?

A double-pane window consists of two panes of glass inside a frame, separated by a little gap. 

To make the window more energy efficient, the cavity usually contains an air pocket or gas—typically argon, xenon or krypton. 

This air pocket keeps the internal air temperature constant by blocking the impact of outside air temperature changes.

The Advantages of Double-Paned Windows

Condensation from windows can cause structural damage to your property, as well as the development of mold and mildew. 

By absorbing atmospheric moisture and humidity, desiccants in double-pane windows keep them dry and protected against damage, corrosion, mildew and bacteria. 

These windows also increase a home's insulating value by encasing air or gas between their panes. 

No matter how cold it gets outside, you can always stay warm inside thanks to this gas layer, which lowers the heat transmission between the indoor and external temperature zones. 

In the summer, the gas layer reduces solar heat gain, making your home cooler.

The insulated gas layer does much more than improve a home's heating and cooling efficiency. It also dampens sound waves to reduce noise transmission. 

Windows with wider gaps tend to have the best sound insulation properties. 

The Cons of Double-Paned Windows

When the desiccant in a double-pane window becomes old and stops absorbing moisture, it creates a hazy appearance in the form of a foggy window. 

This condensation becomes worse when the glass encounters temperatures below the dew point. 

Even though you can have a window expert change the desiccant, others say it's better to just get a new unit.

Another drawback of double-pane windows is their noise-reduction potential. Even though they can reduce noise by as much as 50%, the triple-pane versions can reduce it by 20% more. 

If you want to use these windows to reduce noise, keep in mind that windows with smaller gaps between the panes provide less noise reduction. 

This is because the smaller the gap, the higher the amount of reverberation. In fact, windows with extremely small gaps can actually amplify sounds more than reduce them. 

Are You Looking To Replace Your Windows? 

Replacing windows is a fairly straightforward process. However, it can be quite time-consuming and requires expert knowledge. 

This is why it's best to let a professional window replacement company handle the installation for you. 

Experts can remove the old windows, prepare the new openings, install the new units, add insulation, trim and sealant, reinstall stops and apply primer and paint. 


When it comes to making your home more energy-efficient and comfortable, double-pane windows are one of the smartest investments you can make. 

They not only increase your home's value, but they also result in lower heating and cooling expenses. 

Scheduling a window inspection is one of the easiest ways to ensure you choose the right windows for your home.
