How Do Double Pane Windows Work?

Double pane windows, also sometimes called dual pane windows, are windows that have two panes of glass inset into the frame of the window. The panes of glass are separated, creating an insulating air pocket that inhibits heat transfer much better than single pane windows.

The separation between the panes of glass can vary, but it is approximately a half-inch in most windows. Depending on the window manufacturer, the separation may be filled with a non-toxic insulating gas to further insulate the window. All Weather Shield double and triple pane windows contain inert insulating gas to improve energy efficiency.

What is Conduction in Windows?

Conduction is the transfer of heat between materials and varies depending on the type of material used. Most windows are composed of one of four materials: wood, vinyl, aluminum, fiberglass, or a combination of these materials. The low conduction properties of insulated double pane windows combined with a low conduction material like fiberglass, wood, or vinyl can create exceptionally energy efficient windows.

Advantages of Double Pane Windows

Double pane windows have several advantages over single pane windows. The most notable advantages are:

  • Better insulation – double pane windows, especially those with insulating gas, offer superior insulation.
  • Noise reduction – better insulating properties not only help regulate the temperature in your home, they also help insulate against exterior noise, making them especially beneficial for homes near roads, train tracks, or other sources of noise.
  • Lower energy bills – superior insulation from double pane windows decreases the amount of heat transfer in your home, lowering the work load on your heating and cooling systems – the highest source of energy use in the average home.
  • Increased comfort – decreased heat transfer will not only help lower your energy bills, but also increase the comfort level of your home. Double pane windows will help eliminate uncomfortable hot and cold spots in your home, allowing you to enjoy all rooms without discomfort.
