If you're in the market for a window replacement, you may be researching the pros and cons of different types of windows to make the best choice for your residence. There are three main types of windows available on the market today: Single-pane, double-pane, and triple-pane windows, all named for the number of glass panes situated in the frames. 

These three window options offer different benefits, and which is right for you will depend on greatly on where you live. O'Sullivan Installs has been providing exceptional window installations for homeowners throughout Massachusetts and New Hampshire, and offer expert guidance to our customers on which selection will best suit their budget and offer the necessary protection for their properties.

Single-Pane Windows: Pros and Cons

Single-pane windows consist of one sheet of glass and were the industry standard for residential remodeling until the 1960's. Many older homes may still have single-pane windows installed. The main benefit of these products is their affordability—no matter the size or style, most single-pane windows cost under $200, making them an excellent option for quick fixes and spaces requiring less insulation, such as:

  • Sheds
  • Garages

Unless you live in an area with a consistently mild climate such as Hawaii or the inland Southeast, single-pane windows aren't typically recommended on homes, as they offer poor insulation during winter months, and little-to-no protection when severe weather hits. 

Double-Pane Windows: Pros and Cons

Double-pane windows feature two panes of glass with air sandwiched between. The second glass layer provides improved insulation, and oftentimes the space between the panes is filled with krypton or argon in order to take energy-efficiency up a level.

Double-pane windows offer additional benefits to homeowners in moderate climates as well, including:

  • Allow for Ample Natural Light
  • Reduce Noise Pollution
  • Increase Resale Value of Homes

The only real drawback to a double-pane window installation is that you will end up paying more than you would for a single-pane window, but when considering how much you'll save on your monthly energy bills, this cost will typically even out in the long run.

Triple-Pane Windows: Pros and Cons

Triple-pane windows are made up of three glass panes, with the two internal spaces being filled with air or the inert gases mentioned above. These heavy-duty products protect homes in extreme climates prone to bitter-cold winters, hurricanes, high wind speeds, and more.

Along with superior insulation and the best-quality noise cancellation, triple-pane windows also offer a great sense of security, as the durability and added layer make them much more difficult to break into. 

As expected, triple-pane windows will run homeowners the highest cost, typically 10% to 20% more than their double-pane counterparts, and may not make up for this pricing in mild or moderate climates where the highest-standard insulation isn't necessary. On top of this, another possible setback of these windows is that natural light may be slightly more blocked out than with single or double-pane versions.

For our customers throughout Massachusetts and New Hampshire, O'Sullivan Installs only suggests single-pane windows for outbuildings, while double or triple-pane windows can both provide exceptional insulation, depending on proximity to the coast, where higher wind speeds are experienced. 

We do what we can do keep our pricing competitive to the area, so that our customers have access to energy-efficient window replacements that will keep their homes and families protected all year round.
