Condensation forms on the outdoor surface of glass when its temperature drops below the outdoor dew point temperature. Evolution windows are manufactered using thermally efficient glass. The glass keeps heat inside the rooms of your house and reflects heat from radiators and fires back into the room. As a result, the outer pane of glass does not get warmed by heat escaping from inside the building through the glass and remains cooler in comparison to much less thermally efficient windows.
It is possible that external condensation will appear on the same windows but not on others, due to the position of windows in the house. If condensation appears externally on your windows, this is in no way a defect of the unit. It must be seen as a positive indication that your windows are thermally efficient and are reducing heat loss.

I'm just wondering whether there are any downsides other than diminishing returns. It is possible to install interior storm windows, yes, but there is a cost involved and depending on the condition of the main frames some condensation may get stuck between the panes which is why they often unclip or swing out so interior cleaning is possible.
Depending where in the world you are and the temperature and humidity differential between inside and outside, one simple and cost effective temporary improvement for the winter months can be to install a clear window film inside that tensions with a hairdryer.
Also, work on that all important ventilation, and the reduction of the interior humidity by all the suggestions in the article. Hi August, can you elaborate a bit on your question? Not sure if you mean insulation of the frame, around the frame, or even the insulating pockets of gas or air between panes.
Condensation forms on cold surfaces, so the warmer a surface is then the less risk there is of condensation forming. Triple pane windows are war mer than doubles, so less moisture from the air will condense on it, same goes for frames and even the rough openings if they aren't properly insulated to protect against thermal bridging.
I'm not sure if that answers your questions but feel free to go into more detail. My bedroom window is about 6. Every winter when I open the curtain the window and wall are covered with water. The metal frame is also. Sometimes I use a towel, but most of the time I just leave it. It is horrible. The floor tile was yellow, there is still black mildow in the corners, but it is much better than it was, I think I will never get it all cleaned up, but at least if I can stop any more moisture issues and more mold and mildew growing that will be a great help.
My curtain has turned a bit orange in places now and another pull down curtain inside is black, I don't know how to clean it I have wiped down the big areas of the curtain that were problematic but I need to wash the whole thing, I know. So a thought I had is run a small, quiet dehumidifer behind the curtain during the nights while we sleep in order to suck up only what is behind the curtain, but the smaller ones may not be able to do enough.
The ones I have found can only take about 10oz of water ever 24 hours, that is not nearly enough for the problem. And I do not want to put the big machine behind the curtain, it is loud and overkill and it is not good to sleep with a dehumidifer on as it is.
I have no plants in my room. And like I said, we keep it dry doing the day, but that window faces NW, no sun in the morning, and the temp difference is part of hte problem I think. I need to get the condensation under the control. I have even considered to run a small clip fan behind the curtain to just get air flow, but doubt it would work. I am going to buy some damp boxes to suck out the moisture from the air behind the curtain as well, but those are very slow, usually they are for closets, so doubt they will be effective Do you ever put put plastic over the windows?
I think that would help a lot. There is seems to be a lot of moisture in the room, I don't know why that is but that is also worth figuring out. But as for avoiding condensation, I think the plastic is the first step as it will be a much warmer surface than the glass, so that will cut down on moisture accumulation a lot.
My other suggestion would be to run a fan. You say you don't think it would work, but I think you may be pleasantly surprised. It would be difficult for condentation to form on a surface that has a breeze blowing across it. It should also be quieter than a dehumidifier. Lastly, if all else fails, if you lay a towel or something absorbent at the base of the window that you can remove in the morning and dry out, it could also prevent water getting to places where it can do harm.
Hopefully something in there helps! It seems like you have a pocket of cold air trapped between the curtains and the window. To prevent condensation, every surface in the pocket needs to be above the dew point of your indoor air. When I close the curtains in my bedroom on a cold night 20F or so , the air temperature in the pocket drops to about 45F. The window pane temperature is even lower. You need to raise the temperature of the air in that pocket above the indoor air dew point.
The fan suggestion might work, by pushing warm room air into the pocket. Leaving the curtains open would do the same thing. In theory, completely sealing the pocket off from indoor humid air would work, but I've never tried that. Sign Up to Comment. The thing about condensation on windows, is that there can be a number of causes. What climate zone are you in? I some regions there can still be quite a bit of humidity even in cold air, that could be a factor. Here is a good page to start reading that may have your answers —.
Condensation on windows and how to deal with it. Humidity in homes can be from drying building materials, and general human occupation of a home such as cooking, cleaning, bathing, etc, and whether or not you have sufficient source removal in the form of bathroom fans and range hoods. The quality of your windows will also impact how much ice you see forming, because the glazing surface of lower quality windows will be cooler and that will lead to more condensation.
Do you use bathroom fans when showering? And your stove fan, do you use that as well? Other things that can help would be stuff like putting lids on pots when cooking, shaking snow off boots and jackets, not leaving clothes to dry inside etc. Do you also have a dehumidifier in your basement?
That would be a smart addition too. Condensation on double-glazed windows in cold climates is fairly common unfortunately. Despite being common it can be a problem, particularly in extreme cases, which yours seems to be. First I would point you to a page we have that should give you all the info you need —.
Condensation on windows — what causes it and how to stop it. But running all the way down the wall to create a puddle on the floor is quite a lot. In order to be able to fix your problem, I would first recommend you get a hyrometer, which will measure the relative humidity in your home. As for the source of humidity — here are a few more questions — do you have basement and is it humid? Do you have and use a stove hood, and does it vent out? Do have you have and use a bathroom fan?
And how old is the house - do you know the year it was built? The answer is actually pretty easy but not one you probably want to hear, and I know I risk getting lots of different opinions and comments - but in our opinion you should probably remove the poly vapor barrier.
Any moisture that may have leaked in through unsealed windows would be a drop in the bucket compared to the amount of water in the concrete foundation , which takes years to fully dry. And even that can only happen if it is protected with a membrane to prevent it from absorbing more moisture from the ground.
Either there is no exterior moisture protection separating concrete from the ground and it will just stay wet forever, or it is protected from absorbing moisture on the outside, but still the only way the moisture in the concrete can dry is to the interior, which is currently being stopped by your poly vapor barrier.
So the short story is, despite that fact that so many builders keep putting vapour barriers on the interiors of basement walls, it is the worst thing you can do down there since the main source of moisture is not interior humidity in the air, it's the wet ground and or the concrete itself. Here is an article that will better help you understand why the walls are wet and how renovations should be carried out - ]. Having to remove all the poly is probably not the news you were hoping for but you are at least fortunate in the sense that there is no drywall on at this point.
Most people only find out their basements are rotting many years after they've been finished. We can help you with whatever steps you take moving forward, so feel free to send along some pics if you can, or at least let us know the following - Are the wood studs right against the foundation or is there any rigid insulation panels or membrane separating it from the concrete?
Is there any damp proofing spray on the exterior wall, and or a dimple membrane? Do you get condensation on windows in the home? All are factors to consider for health and home durability.
