Difference Between Single vs. Double Paned Windows

Difference Between Single vs. Double Paned Windows

If you’re looking to upgrade your windows, consider replacing your single-paned windows with double-paned ones. There are pros and cons to both types, but double-paned windows have far more benefits than the single-paned style. In order to better understand the benefits of upgrading your windows, this article will break down the difference between both styles.  

What are single-paned windows? 

Single-paned windows are the most simple, standard style of windows, and are made with a single layer of glass. They are less common than double-paned windows, and are usually found in older homes.  

Pros and cons of single-paned windows 

Most homeowners install single-paned windows in their home due to their lower cost, but they aren’t common in newer builds or homes that have been recently remodeled. Since they only contain one layer of glass, these windows are poor insulators. The outside weather can affect the temperature of the glass, which in turn affects the temperature of the house. Because of this, the lower cost of single-paned windows and installation are usually negated by higher energy bills down the line. If you live in a fairly mild climate, single-paned windows might be appropriate, however in the Mid-Atlantic our temperatures swings suggest double-pane windows are the best choice. 

What are double-paned windows? 

Double-paned windows are also known as double glazed windows, and are similar to single-paned ones except that they have a second layer of glass. This style was developed in the 1930s and was designed to add a gap of air in between the two layers of glass to add insulation.  This style now has an inert gas between the panes to act as an insulator.   

Pros and cons of double-paned windows 

The gap of air inside of double-paned windows acts as a barrier between the weather outside and inside your home, which improves your home’s energy efficiency and reduces your energy bills. This barrier is also effective in reducing outdoor sound, making your home a more peaceful space with less noise pollution. The initial cost of double-paned windows is slightly higher than single-panes but is made up for in energy savings and an increased resale value of your home.  

When should you upgrade your windows to double-paned? 

 

If you still have single-paned windows, upgrading to double-glazed ones is a good investment for your home.  

Here are good times to install double-paned windows: 

  1. If you’re looking to sell your home in the future, upgrading your windows has proven to provide a good return on investment 
  2. If you’re noticing your home’s insulation is lacking, or you are looking to save money on your energy bills, upgrading to double-glazed windows with a high R-value which measures a window’s insulation is a good place to start. Depending on the size of your home, you could recognize hundreds of dollars in energy savings annually. 
  3. If you are building an addition or looking to change the façade of your home. It’s a good idea to fold new windows into your renovation budget. 

How do I know if I have double or single paned windows? 

Determining if you have double or single-paned windows is easy. Your first clue is the age of your home. If your windows were installed before 1980 they are likely to be single paned windows.  

To be certain, take a look at your window’s outside edge where the glass meets the window sash. If you have double paned windows, you will see a metal divider at the window’s outside edge.
