Is Your View Blurred on Rainy Days? Fix Your Foggy Windows

Are rainy days blurring your windows? Fog in your insulated glass could be the culprit. To figure out the reason for your foggy windows, you must first identify where the fog is taking place. Is the fog on the interior, exterior or between the panes of glass?

What Causes Your Foggy Windows?

Fog on the inside of the window occurs when the temperature inside your home is lower than the outside temperature. On a hot, humid day when your AC’s blasting, this is a normal occurrence. The glass naturally becomes the coldest spot in your home, causing the condensation.

The exact opposite situation causes condensation build-up on the exterior of the window. When the temperature on the outside is lower than the temperature inside your home, the result is moisture on the exterior glass. Interior condensation is frustrating because it dampens your furniture, window frames and wallpaper.

Moisture and condensation build-up between two panes of glass is when you have a real problem. This is a clear indication that you have an insulation problem with your glass.

Insulation Problems Pose Risks

When there’s fog building up between two sheets of glass in your windows, the likely answer is an insulation issue. Older windows typically allow rain, fog, and snow to seep through the seal, which is an easy way to damage your windows and decrease energy efficiency. The fog is actually condensation on the glass in between the panes. The moisture builds up causing damage and blocking your view. In addition, the windows will continue to allow heat and/or cool to escape.

Protecting Your Windows

The most energy efficient windows to date are double pane or triple pane windows. The windows efficiency is due to the application of argon and krypton, extra panes, and the use of coatings. Not only will these elements minimize condensation, but also lower your heating bills during the winter and cooling bills in the summer. Unfortunately, if the seal fails cold air and warm air enter between the glass panes, leading to higher energy bills.

Insulate Your Glass

So how are insulated glass units made? IG units are windows made from two or more panels of glass separated by a sealed air space. The metal tube around the perimeter of the insulated unit that separates the two panels of glass is called the spacer. This spacer comes in thicknesses of 3/16″ and larger. It is filled with a special moisture-absorbing material called a desiccant. The perimeter of the entire unit is sealed with a high-grade sealant.

So How Do We Do It?

We take large sheets of flat glass cut to size based on your dimensions. Before the glass can be assembled in an IG unit, we thoroughly clean it. We load the glass onto a conveyor that feeds the glass through our washer.  The glass washer uses carefully maintained water and cleaner solutions to remove all impurities from the glass surfaces. Next, we add spacers between the glass to ensure the perfect space between panes. If the unit requires the inclusion of grills between the glass (GBC), we insert the GBC to the unit. Lastly, we feed the assembled IG unit into our glass seal oven. Our oven heats the unit to a specific temperature and feeds the unit through a press that provides the final seal between the glass.
