Why Do Home Windows Get Foggy?

Construction & Contractors Blog

Do you notice fog on all the windows in your home? If so, it might be time to replace them with new ones. Foggy glass occurs for a number of reasons, and it generally means that the windows are not as efficient as they should be. If your windows are old and foggy, they are probably drafty too, and replacing them is the only way to improve the efficiency of your home.

Why Do Windows Get Foggy?

Fog on windows can be caused by several things, but the first step you should take is to determine where the fog is located, and it could be in one of three places:

  1. Exterior – The only time you should see fog on the exterior side of your house is on a really humid day. This can occur if you have the air conditioning on because the cold air on the interior meets the hot air on the exterior, and this causes moisture to form outside.
  2. Interior – The opposite is true for fog on the inside of your windows. When this happens, it is because of the warm air inside your house is meeting up with cold air outside.
  3. Inside the glass – Moisture inside the glass usually means that the seal in the windows has broken, which means that water is actually inside your windows.

No matter where you see the water, it is never a good thing. When windows get foggy on any of these three areas, it is because the windows are not holding up as well as they should. Windows that are efficient are insulated enough that the temperature differences inside and out do not create condensation.

What Should You Look For In New Windows?

Almost any new windows you get will do a better job than your old windows when it comes to stopping airflow, but there are several things to look for in the new windows you select for your house.

The first thing is the u-factor, which is rated from 0.2 to 1.0. Lower numbers are better because they represent how well the window blocks heat from passing through a window. One other factor to look at is the solar heat gain coefficient (SHGC), which is rated from 0 to 1. Again, lower numbers are better because this represents how well windows can block the heat from the sun.

Getting new windows can make a big difference with your energy bills and with the way your house looks. For more information, visit http://www.newjerseywindow.com or a similar website.
