The interior window condensation is formed by the moist air in the rooms, and converting to water on cold surfaces. The window panes in this case would be the colder surfaces. If the moisture shows up on the exterior of your home, and it is very cold outside with ample moisture in the air, you have another recipe for condensation to form.
@@john99776 Most dehumidifiers don't go below 35%. My windows still sweat and have water pooling on mine near where the bottom sash and window frame meet. They caulk the area but water comes through the caulk (i guess it is the coldest part of the area). My window manufacturer says to keep humidity below 30% when it is below 20 degrees. How the heck am I supposed to do that?
@@john99776So now that I’ve sealed by house up, on the promise of energy efficiency & savings, now that I’ve done allll that, I have to payout more to get a dehumidifier, which I had never needed before, pay to have it installed (maintenance not included)& and pay for the energy used to operate it? Wonder if the real numbers & math tell would tell me a lie too? Seems in our haste to achieve our goal we only look to the peak taking steps without looking if they’re forward or backwards.
@@Tbay007 bro you just need either triple glazed windows, or you need some other additional barrier, like plastic or storm windows so that the innermost pane of glass does not get below the dew point.
I work for Window World and I am in Birmingham, Alabama point. This video was perfect as I had this happened to me with a sliding glass door that is right by Customer‘s kitchen. She did not take my word for when I talk to her and told her that the window was fine. When I showed her this video, she totally got it, thank you very much, sir
Guys you cant prevent from the condensation if a temperature is different between outdoor and indoor. No matter how new windows you get the condensation will be there, especially during the winter if you dont open the windows to refresh the room in a very cold days. All you need to do is to use some dehumidifiers around the house by placing them on the windows.
We have louvered blinds on our new windows. North side master bedroom window gets no sun in Wisconsin winters. Our room stays cooler than the rest of the house and we get the condensation on that window. We leave the bottom of the louvered blinds about and inch off the window seal and open the blinds just enough to allow warmer air to pass through to the window. It helps until the zero temps hit and then raising the blinds or opening them all the way gets the condensation to go away.
In Germany they saw through this problem and figured that the rubber inlays are possibly installed wrong… manufacturing problem, yet the use double - double glass windows and they keep the temp around 21.4 degrees Celsius and they get no problem like this.Also it depends on what the material that your house was made of.Anything that absorbs moisture will give back later on and mold will be able to grow.
Yep you are managing humidity vs temperature differentials the right way. Glass only tells you, you have to make an adjustment to managing routines.. Through winter I run the furnace fan 24 seven, shower fans as needed, and stove fans when stemming/cooking. When I have differentials of -15 C and lower outside to normal +20-21 C inside I crank down inside to 18. And Blinds WELL THE curse so few realize the effect and damage created by incubating your glass and creating a closet of still air that hits dew point and unloads precipitation. Then the game is on as the knew lower surface chomps and draws on more delicious dew point 31 years in the window business..................seen it all................same old..same old.
Basically, condensation forming in your windows (so long as it's not inside the interior of a double pane window where the dessicant is) is completely normal if the difference between inside and outside temperatures are high enough. You can't do much to stop it. It's just an indicator that the window is doing its job. You can get more panes of glass to reduce it, sure, but you would need an impractical amount to stop it completely. Any three-pane window will condense if it's, for example, -1°C outside and 22°C inside, especially if it's over 70% humidity inside. Just imagine the conditions of colder areas. The only way to stop it completely is to use the radiators below your window. However, you'd have to keep them on all night, which is a waste and not really respectful with the environment. Just open your windows once you see moisture, and close them when you can't see condensation anymore (this can take more than an hour). Try to keep it to a minimum by pulling down blinds and curtains.
Pulling down blinds has the exact opposite effect for my windows! It creates even more moisture on the windows because the air is even less circulating and that keeps the moisture on the window instead of circulating in the house. Maybe you wanted to say to pull up the curtains and blinds? Also, opening windows isn't practical in cold weather especially if the heating bill is huge and you can't afford it. Could a dehumidifier help a lot maybe?
In Europe, they have double-pane windows/double glazing with a thermal break between the panes, it costs a lot more, and you still get condensation inside. They also have vents that can be slid open to let some air in, which helps a little. I turn on the dehumidifier during cooking and shower times, and that helps too.
Why is no one ever talking about the seal around the window? In the winter months cold air can come through the uninsulated bordet behind the trim and reach the inside worm window glass. Lots of condensation issues from this.
That can be a possibility, but warm surfaces will not condensate. If the air is leaking past the window frame, there are bigger issues than just condensation on the glass.
You need to insulate around your windows period. You should not have air gaps around your windows. Pull your trim and insulate with low expansion foam or fiberglass insulation. If you use fiberglass be sure to not pack it to densely as this will actually transfer the cold. Hope this helps you😊
Good lesson, good speaker, thanks, - but the bad disturbing, unnecessary pounding noise, why? .The cause being excess humindity seems strange, since I learnt that the air indoors is too dry during the winter!? Have to check the ventilation, it is annoying when the noise disturbs. Ventilation-overtones are even dangerous for health.
I am in Florida and it is very humid and hot outside. We use air-conditioning and it is not possible to open the windows during the summer months, the entire house would be humid and moldy. During the summer time I have condensation in my windows and a lot. What can I do about it?
grit residue on glass panes that is left on the glass after 'cleaning' is often why they fail early,,, guys in the asembly area use the house mix of blue window spray cleaner,this plastic 'grit' is applied after the glass is cut into sheets then packed tightly in wooden crates, what removes this 'grit' is rubbing compound pumice that od time glazers used,or cerium oxide,, applied with a wet clean rag and warm water,wipe off till dry,one more dusting w the cerium powder,=,clean glass,,the grey adhesive used to join the 2 panes together will stick snug on the glass and not fail for 30 years
just lower the humidity, now trouble is, have to often open a window for that, kinda defeats object right... even bran new windows can suffer, need nearer 50% and not closer to 60% plus..
Hi there, the answer is it depends. What type of interior condensation do you mean? A lot of interior condensation can be attributed to sealed up windows and high humidity within the room. If you mean structural condensation like on an aluminum framed window, that is based on the aluminum not being a great insulator and not so much the glass if it is high performance dual or triple paned units.
It doesnt, i have high quality 3 pane windows and still get condensation when outside is below 0. I measure moisture and its always 40 60 so it in healthy range. I am afraid that window condensation actually dryes the air making it unhealthy. You can cover the window to limit contact with air
Much of the condensation here forms in the winter, especially on the coldest days when it's not practical to be opening windows for hours.
Use a dehumidifier

Vents in my window were a nuisance I've them packed with foam and covered them with aluminum tape , when the room needs fresh air just open the window
@@ElDubz420 I guess it depends on the climate. They worked great for us, living in the UK.
@@rickcrammond6330 yeah true i suppose especially this time of year when you got heating on more

Any work arounds (for interior condensation) when it’s less than say, 20F outside? Don’t wanna open windows and let frigid air inside the house
What so you sleep in cold weather with your windows open 🤔

grit residue on glass panes that is left on the glass after 'cleaning' is often why they fail early,,, guys in the asembly area use the house mix of blue window spray cleaner,this plastic 'grit' is applied after the glass is cut into sheets then packed tightly in wooden crates,
what removes this 'grit' is rubbing compound pumice that od time glazers used,or cerium oxide,, applied with a wet clean rag and warm water,wipe off till dry,one more dusting w the cerium powder,=,clean glass,,the grey adhesive used to join the 2 panes together will stick snug on the glass and not fail for 30 years
So whichever window is sweating, crack it?
Does the condensation does it turn white some people think its mold
Another informative and well explained video.
Thank you Nathaniel!
just lower the humidity, now trouble is, have to often open a window for that, kinda defeats object right... even bran new windows can suffer, need nearer 50% and not closer to 60% plus..
If the seal is broken will that cause a room to not cool down?
my concern of leaving windows open too long is creepy spiders and annoying flies getting in
Hi our window just change few days ago but we see condensation inside glass
Same
how to open the window in cold north east winter

absolutely, the triple pane surface is warmer than a dual pane and warmer is better when you don't want condensation.
Thank you for the information.
It stopped showing up for me because i had them open like 1 cm for months
I fell stupid now, I spend most of the time in my room on computer and never realized "Ohh maybe I should open the window now and then"
Dude this is the stupidest advice ever!!!! Don’t share stupid things… just don’t record anything…
