Installation of Energy-Efficient Windows

Only professionals or very handy, experienced homeowners should install windows. A poorly hung window can be very inefficient. Here are some tips:

 

  • Make sure the windows are squarely installed to prevent air gaps.
  • Spray Great Stuff or other foam insulation in the gaps between the wall and the window frame.
  • Caulk all the way around the inside and outside of each window.

 

An energy auditor can measure the leakage around windows. A blower door test will show if air is seeping in around the window frame. If the windows are well-sealed and the home is fairly airtight, be sure fans and ducts are working properly. Otherwise, you may seal in indoor air pollutants.

 

Window frames can make a major difference in overall home energy efficiency. Carefully consider the style, material, and installation before replacing windows.
