New home windows fogging up

So we'll see what happens. Happy to know it's supposedly normal, but if reoccurs with little temp change or only rain they will replace. Hope that isn't necessary! What would they replace it with? The only thing that would prevent it from re-ocuring would be less efficient glass.

I'm a little confused by that too. Saying it's normal, but also saying others have only had fogging occur a couple of times when first installed and others had it repeatedly occuring and resolved when replaced with new window of the same is a bit of a condradiction.

What was odd was the perfect symmetry of the fogged area, like a smaller perfectly cut frosted glass was layed over the center. Also odd that last night it poured rain was much cooler out and warmer in and no fogging.

Beats me. I have the same problem with my newly installed dual pane windows. It occurs mainly on all my west facing windows. I panicked when I saw this too and called the company who installed them. He had me speak with the sales rep in the area, who told me it was normal. I believe they should warn people about this. It is rather annoying not being able to see out any windows in the morning.

It last for several hours too. I did not have this in my last house, but those windows were installed when the house was built and were not retrofit windows. They also were not low e. So, the low e might be the main problem. Fogging on the outside of the glass is normal and actually means the window is working well by preventing the heat from the home from transferring to the outside surface. This will become more of a problem as triple pane windows become more popular.

There are some folks entertaining putting a low- or mid-emmissivity coating on the outside surface to prevent since this would prevent the glass from signicant radiant cooling that causes it to drop below the dew point. I need a coating like this on my car windshields! Like NEAT it is an "easy clean" surface 1 coating but with the intended added benefit of eliminating surface 1 condensation - basically morning or evening dew. Two weeks ago my daughter is reading the forecast for the next week actually last week and she says "oh good, it's going to be above zero all next week, well except for in the morning when we go to work, it will still be below zero then".

Yep, I am tired of scraping my windshield! I think we have well passed 50 days total below zero this winter and we have hit or colder maybe 7 or 8 times.

Not to mention the five or six feet of snow. You know it's a real winter when you go outside wearing a sweatshirt no hat or gloves and you think "not bad at all kinda nice out", then you look and it's eight below zero. Kinda reminds me of winter when I was kid Did the window fogging ever stop? We have the dame story Did Home Depot fix problem? And how?

Only way to "fix" the fogging is to replace the glass or sash. The seal is broken and is not fixable. If it is between the panes, you will need to have the glass replaced and this will be clearly evident because the condensation does not go away with the change of the daily temperature. Less than a month ago we had new windows installed in our home.

We have noticed that with the cooler nights and some nights where it has rained we are getting fogged up windows On the outside! The first time it happened I reached out to the salesman, and he told me, that this was normal.

It has now happened several more times. It starts at around 9 pm. This fog stays on the windows all night, and does not dissipate until after 9 am in the morning. This is very disturbing and embarrassing when we have company over for the evening I find it hard to believe that this is normal.

To me it is an indication that the windows are failing, whether from installation or the window itself. Living in the lower mainland of BC, where we get rainfall 70 percent of the year, I feel that I am being fed a line and that I have just wasted thousands of dollars on substandard windows.

Has anyone had this issue with their new windows? Also, with the last rain we had, we also found that on several windows there were thousands of water droplets left on the outside of the window. These water droplets took half the morning to disappear. Once the droplets disappeared, it left water marks behind.

Not impressed AT ALL. The first 2 pictures attached are taken from the inside of the house, but the condensation, or fog is actually on the outside as shown in the last picture of the patio door. The other picture is all the water droplets after the rainfall. In regards of this supposedly being normal Why was I not made aware that fogging may be a possibility? To be told once the windows were installed, and I reported the issue , that this behavior in normal is unacceptable.

It can be a normal phenomena depending on the moisture and temperature conditions of the outside air. What kind of Low-e did you get in the patio door? The windows are double pane with argon gas low-E , u-factor. The fogging can happen on all the windows throughout the house and has. There are plenty of reasons for moisture build-up, and a few of them are simple fixes.

What Causes the Fog? To figure out the reason your windows are fogging up, you must first identify where the fog is taking place. Is the fog on the interior, exterior or between the panes of glass?

Water is forming on your new windows because one of several things is happening. The temperature of the inner glass surface is at or below the dew point for the amount of humidity in your inside air. The humidity of your indoor air is quite possibly much higher now with your new windows because the air leaks around your old windows were eliminated once the new windows were installed. Cold, drier air that leaks into homes from the outdoors lowers the relative humidity indoors.

This is one reason people have static electricity problems in drafty homes during the winter months. Dry air makes it very easy for the static sparks to transfer from your hands to grounded objects. This tool will allow you to get accurate readings of indoor humidity. Start to take daily readings and then look around to see if you have things that add too much water to the air. Make sure crawlspace soil is covered with high-performance vapor retarders. This is a fantastic high-quality hygrometer.

It says Psychrometer on it, but that's the fancy name for hygrometer. Minimize the number of indoor plants you might have. Run kitchen exhaust fans if you boil lots of water when you cook. If you have a vent-free fireplace, limit its use as it produces vast amounts of water vapor when it burns natural gas.

Many factors may contribute to a foggy window. Exterior condensation on windows occurs when the temperature inside the home falls well below that outside, like on a hot humid day. When dramatic differences in interior and exterior temperatures and humidity levels occur, moisture condensation can build up on the coldest surface—the glass.

Likewise, when interior humidity is high, as temperatures drop outdoors, condensation can occur on interior glass surfaces. To protect your investment in your home and home furnishings, reduce the level of interior moisture inside your home. The use of a dehumidifier may help alleviate the interior glass condensation. Moisture and condensation between panes of insulating glass can occur when the seal between the panes of glass fails and allows moisture to leak in.

This typically occurs in older windows or doors. This same fogging can occur on any side of the home but tends to be more visible on the sunny sides because the additional heat from the sun can accelerate the seal failure.
