Examining Insulated Windows: Advantages and Disadvantages

Insulated windows use one or more techniques to minimize heat transfer through the window. Because insulated windows are versatile and energy efficient, these common windows offer a number of advantages.

Advantages

The advantages of insulated windows are:

  • Versatility. Insulated windows are double or triple paned. They include one to several low-emittance (low-e) coatings that offer insulation against heat and cold. Low-e coatings can be added to any window type. Insulated windows perform well with all materials, but wood, vinyl, and fiberglass are the most common.
  • Energy efficiency. Insulated windows help reduce the power requirements of the home by preventing heat loss during the cold season and keeping cool air in during the hot season. A window that isn’t insulated can have a surface temperature of 30 degrees or lower. For an insulated window, the temperature jumps to 56 degrees.
  • Noise reduction. Insulated windows, whether double or triple paned, help reduce the sounds of noises from outside the house. The air between the panes doesn’t allow as much noise to pass through. Adding insulators such as argon or krypton gas between panes can reduce noise even more.

Disadvantages

The disadvantage of insulated windows is: 

  • Cost. Insulated windows can cost twice as much as other types of windows. Installation costs more too. Although initial costs can be high, the savings on energy bills will eventually catch up to the costs for the windows, and then some.
