Energy Efficient Doors and Windows

New and replacement doors and windows
Energy efficient doors and windows are an essential component of thorough insulation and air sealing. Replacing old doors and windows of existing buildings is the most complete method of lower heating and cooling costs and more efficient energy use.

If you’re building a new home, you should consider buying the most energy-efficient doors and windows possible. When selecting doors for energy efficiency, it’s important to first consider their energy performance ratings in relation to your climate and home’s design. This will help narrow your selection.

Storm doors and windows

Storm windows are an economical way to increase the efficiency of older, single-pane windows. They reduce the flow of outside air into your home. The airspace between the storm window and your existing window works as added insulation. Adding a storm door can be a good investment if your existing door is old but still in good condition. However, adding a storm door to a newer, insulated door is not generally worth the expense since you won’t save much more energy.

Weathersealing older doors and windows

Small cracks and crevices around doors and windows may not seem like a problem, but did you know that a 1/8″ space between a standard exterior door and its threshold is equivalent to a two square inch hole in the wall? Closing those gaps can save you up to 15 percent in heating and cooling costs and also can reduce the demand on your heating and cooling system.

Energy efficiency for doors and windows is achieved by:

  • Weatherstripping around standard doors and windows
  • Storm doors and storm windows
  • Replacing old doors and windows with new energy efficient models
  • New construction using energy modern designs
