Sure, foggy windows in your home are annoying, but they may also be an indication of a larger problem. If you notice fog in your windows, this is usually a sign of poor insulation.
A properly insulated window should prevent fog from forming. However, if this isn’t happening, it’s probably time to replace your window. The reason for your foggy windows could be due to worn seals, or damaged glass or sash. Your local window manufacturer will be able to help you with any necessary repairs.
In the meantime, there are a few things you can do on your own to resolve the issue. Here are several tips for what to do when your windows get foggy:
Why the Windows in Your House may be Fogging Up
Foggy windows in your home can be largely attributed to worn or damaged seals. Insulated windows are designed using two glass panes with air filling the space between the panes. Argon or krypton gas air is used to enhance the energy-efficiency of your windows. This, of course, helps to keep the air inside of your home from escaping.
Most windows also contain an insulated glass unit (IGU). The IGU increases the energy-efficiency of your glass windows by doubling the R-value. Over time, the seal around the IGU can experience wear and tear, causing your windows to fog up.
There are many reasons your window seal may become damaged:
- Water Exposure: You should check your window seals after there has been a heavy rainstorm or flood. Too much water exposure and water buildup can damage your perimeter seals.
- Excess Heat Exposure: Because warm air expands, the air between your window panes can stretch out your seals and cause damage. This is a particular concern in warmer months when your windows receive more direct sunlight.
- Aging Windows: Every few decades or so, you may notice fog on your windows that just won’t go away. Wear and tear from everyday use and harsh weather conditions can damage the seal around your windows over their lifespan.
Fog in your windows forms when moisture seeps between the glass panels and condenses. The fog is most noticeable in cooler weather when heat from the interior mixes with the cold air outside.
Can Foggy Windows be Fixed?
If you have foggy windows in your home, the best way to fix them is to have them replaced. However, if a complete window replacement just isn’t in your budget right now, here are a few things that you can try:
- Get a new IGU Unit: You can replace the IGU unit or get new glass to replace the second pane of your insulated window. This is a relatively inexpensive repair to make, although it is much more complicated than simply replacing the window. If your windows are a couple of decades old, it’s probably more cost-effective to have the entire window replaced.
- Purchase defogging spray: Defogging spray can be used as a preventative measure to protect your windows from fog. This will keep your windows clear — at least for a while. However, the only permanent fix is to have your windows replaced.
How to Avoid Window Fog in your Home
- Buy energy-efficient windows: It’s important to invest in energy-efficient windows to control your home’s energy use and ensure you’ll have windows that will last you for decades.
- Have your windows professionally installed: Only allow an experienced professional to install your windows. Otherwise, you risk the failure of your direct-set glass and seals.
Foggy windows can be hazardous to your family’s health. The moisture promotes the growth of mold, which is especially concerning for allergy-sufferers. Replace old, worn-out windows and create a safer, more energy-efficient home.
