Paddy's DIY - Window Condensation Part 3 : Between the panes of glass
Another great video brought to you by Paddy's DIY
This video is the 3rd of three, about three types of condensation that forms on windows and doors.
In this video I’m going to be talking about condensation that forms between the panes of glass in double and triple glazing.
When a double glazed unit is being made up. The two panes of glass are glued onto a hollow spacer bar. You will see this as a silver or sometimes black bar in your windows. The spacer bar is partially filled with a silica desiccant. The desiccant is more or less the same as those little packs of silica beads you get in the box when you buy a new pair of shoes. This desiccant removes the moisture from the air that is now trapped between the two panes of glass. If this desiccant wan't here the moisture that is in the air that is trapped between the two panes would condense and cause a fog on the inside of the glass.
Over years the poly sulfide glue that sticks the two panes of glass onto the spacer bar can let in outside air. Like in this double glazed unit, you can see the small gap where the glass is coming away from the spacer bar. When this happens air and moisture now enters between the two panes.
The desiccant can only absorb so much moisture, and when it gets to the point that it can't absorb anymore moisture it forms between the panes of glass. This depends on the outside temperature. In general, during hot weather, the moisture between the two panes of glass evaporates, and can look like the condensation is gone, only to then condense when the temperature drops. It's this cycle of evaporation and condensation that leaves the unsightly staining between the panes. The staining usually coincides with the amount of moisture that is getting in between the two panes, and can be really bad like this double glazed unit here.
Unfortunately, when the seal has broken down the only real solution is to replace the double glazed unit. I've seen some videos on CZcams of guys drilling a hole in one of the panes of glass and washing the stains out. Another taking the double glazed unit apart cleaning the glass, replacing the desiccant and re-gluing the glass back on. I can't imagine how doing either would be better or cheaper than getting a brand new double glazed unit made and fitted.
Anyway, that's all from me, don't forget to give a thumbs up and hit the subscribe button. Thanks for Watching - Jak na to + styl
Hey lovely people! Why not buy me a cup of coffee or a beer to say thanks. Click on the THANKS button above 👍☕🍺
This was very informative and clear. It wasn't the answer I was hoping for, but it helped non the less.
Thanks for the comment
I was searching for a solution for my dirty windows and I just knew I was going to see another "Replace the lot" video. But this one was actually useful, explaining and demonstrating how the problem occurs. At least I now understand why I am having to replace the lot rather that just taking the word of the window salesman.
Thank you for the comment, someone who actually understood the point of the video.
@@PaddysDiy t
The best solution is to replace, but you can have temporary fixes. Try to find the source of the leakage, normally outside downwards, and fill it with some waterproof filler, drill some small holes on top from inside and then use a hair dryer from inside to evaporate the fog. This just works if you could effectively stop water from coming inside.
I was hoping there was an easy fix but now I understand why there isn't. Thanks for taking the time to make this and explain what's going on.
Glad it helped 👍
there's no easy fix, but these guys are professional, they don't want to share easy fixes. Try to find the source of the leakage, normally downward, and fill it with some waterproof filler, then use a hair dryer
Thank you for giving an honest answer on this issue. I have see other videos that, like you said, show someone drilling holes in the glass and using a chemical to clean out the moisture, and seal the holes. I trust your evaluation that this cannot fix the issue, it seemed too good to be true. I am going to replace my 12 year old double pane glass in my doors that have this issue.
Thumbs up to the honest answer, if not to the (inexistent) DIY solution. Thank you.
Thanks for your demonstration. Now I understand why it happens. Also, your sincere solution is appreciated even though it's the most expensive.
Thanks for your comment. A lot of people seem to missing the point of the video
This is EXACTLY my problem and such a shame to have to replace. Thanks for this. Well explained.
Mine too, I have the exact same problem of staining between the glass.
Thanks for explaining it, it now makes sense to change the windows👍
Thank you, now I know....
It behooves us to try as much as possible to fix something as expensive as a window.
Honest, Informational and To the point; Thank you!
very well explained and thank you for posting!
Cheers
thanks for your prof advice. makes sense for sure
Ah man... I was looking for a miracle cure.. great vid and to the point. Makes perfect sense. Thanks
Glad it helped 👍
I'm not seeing the difficulty in removing/cleaning/replacing.
I'll grant you, if your labor is worth anything at all, it's not cost effective.
But I'm mostly retired, and would rather putter than go do a couple of hours at what I normally do to pay to replace the window.
Just looked at my problem window again - looks to be a tri lobe rubber seal.
I know those can be a bit of a pain to seat, but it's not that bad.
Off to find a guide somewhere.
Great video but sad for my wallet, thanks for ACTUALLY answering these questions! Nice one
Great video man. Straight to the point👍🏼
Thanks for the comment
I learned things from your videos. Unfortunately you told me that I’ll have to replace my dbl glaze because of heavy staining. These are sliding doors here in Chicago. I’ll life with it for now because it’s not in the budget. Cheers and peace
I saw those videos, too. And I'm glad I found this one because drilling holes and such seemed like it would cause more problems than fix. So the answer is they're old and need to be replaced. A pity, but I'd rather know that than wreck something trying to do it myself. Thanks!
Thanks for the comment
Drilling a hole would be much cheaper. They blow it out with an air compressor. Then you can caulk the holes back. It will definitely prolong you having to buy a new one
@@redskinswizards3 🙄 nah man you sould fill it up with water and put a few goldfish in it. Diy aquarium
Just seen another use leaf blower to dry moisture out of window go inside then use hairdryer then use a sealent round edges but don't cork it like other sealent a year later windows still going good
I have this on the doubble glazing in my council flat and they won't replace the windows. The best I could do as some form of solution was find the damaged parts of the sealent and reseal it, it doesn't remove the condensation but it stops it getting any worse. Thankfully it's not as bad for the age of them as some of the examples youve shown here.
That's unfortunate. Wish there was a cheap easy solution for you
Great information. I am just wondering when there's water in between window pane, will that caused mold to grow around the window area? Thank you
i don’t think so because my window has been like that for ages and has no mold or anything gross
Yes it does for us. If the window pane is wood, like ours. Ours has got black mold on the inside. The panes are also rotting away
Only if its wood
I used to make IGU's on a small scale many years ago when double glazing was essentially taking off. All I can say is that it is perfectly possible to re-do the units provided it is approached in a professional manner.
Split the unit apart into two pieces of glass.
Reclaim the spacer bars and empty out desicant or buy new pieces and cut them to length.
Fill spacer bars with new desicant and assemble into a "picture frame".
Thoroughly clean both pieces of glass on the sides that are to be inside the completed unit
Attach spacer bar assembly to one pane of glass appropriately set in from the edge of the glass
Lower 2nd piece of glass onto spacer bar and align
Lightly clamp or tape assembly together to prevent glass/spacer bar movement.
Fill the gap between sheets of glass up to the level of the edges of the glass with sealant
Allow sealant to fully cure, (several hours).
Reglaze window with repaired unit.
You will need something to fill the hole in the wall that used to be a window while you carry out repairs
You will need to purchase new desicant, new spacer bar if original cannot be reclaimed.
You will need a flat area to lay down the prepared unit while you fill the edge with sealant and allow the sealant to cure. The sealant will likely be two part polysulphide rather than hot melt (not silicone sealant).
Of all the chores, cleaning the glass will likely be the most difficult. It will be mortifying to be installing your nice re-assembled unit into the window frame only to notice a smear or some dirt inside the unit that cannot be dealt with.
Good luck ! ! ! ! Properly done the unit will be as good as a purchased new unit. No one said it would be easy, but it is doeable
Never said it wasn't possible to do. I said i would be surprised if someone was providing a service of reconditioning old units. The amount of time involved to recondition a unit far outweighs the cost of replacing with a new one. If there is anyone providing such a service, they either don't value their time or have no concept of running a business.
Because what you describe is FAR from an easy diy job. You are experienced doing it, so it would be a lot quicker for you, but still a slow job.
From my experience, the vast majority of people don't even know how to remove a unit from a window / door, let alone undertake reconditioning a unit.
For people who have plenty of time and have a good level of skill, it is totally possible as you outlined. But for 99.9% of people, it's not an option.
The point of the video is to show the reason why they break down, and to show that there is no quick fix.
nooooo i was so excited to see if i could clean it :( i had no idea it was on the inside. my apartment complex will never give me new windows :,(
Ditto! Was hoping for some solution besides replacement
thanks for your help
Its called cost, buying double glazing isn't cheap.
Very useful
JUST THE INFO I NEEDED.
Glad it helped 👍
Good information
i wad advised to blast the windows with a hairdryer, is this ultimately pointless then and any water will just resettle? i've not long bought my house so ive no real idea how old the windows are but i do know theyre prior to a new standard i forget the name of
I'm afraid it'll just condense again when it gets cold.
@@PaddysDiy Thank you
Anyone know the video where they replaced the desiccants. Thx in advanced yall
641 window manufacturers liked this video.
If the joints can be resealed and using high setting heat gun, wouldn't this solution work? I'm definitely going to try this approach.
If you have the time to do it my friend give it a try. Couldn't tell you if desiccant will dry out and be usable again. Give it a go
cut through the sealant as shown, take it apart, clean old sealant, remove and dry desiccant in the oven. reassemble, seal with PU glass sealer leaving two holes one at the top and one at th ebottom bottom. refill with argon, use cigarette lighter as a gauge, seal holes and you have saved yourself a lot of money
I solved the problem of condensation between the glass sheets. in my case, it's 23°C at home and -5°C outside, and of course the condensation appeared between the glass sheets. I took a roll of food foil (plastic), tore it and made plugs from the foil. with these plugs I plugged all the ventilation holes on the profile (outside) and inside the joinery frame (as you open the window on the frame, there are two ventilation holes at the top and two at the bottom). after a maximum of 12 hours, the water remaining between the glass sheets has disappeared. I must also specify the fact that I was lucky that the water between the glass sheets was clean so that once the water disappeared, there were no traces or traces of dust or mud as the case may be. if the condensation combines with dust or earth particles, then after drying, dust could remain. translate with google translate. good luck.

Thanks for the comment, my friend and I'm glad you solved your problem. But i don't think what you're describing is the same as the double glazing we have in Ireland and the UK
Hi Paddy, can't seem to find your website. Is it still running? Or has the company changed name?
windowanddoorparts.ie is closed down, I'm afraid
Informative video. Shit. Now I have to buy a whole new window unit :(
I have jusg drilled 2 12mm holes in oposit corners inside i thknk th juice they use is ispanol alcohol
Has it worked? I was planning to do this too. Thanks
"Tumbs Up" on buying a new window... WTF was the point of this vid?!?
Would you go buy a new car if you got a flat tire? Why would you buy a whole new window when you could replace the section that needs replacing.
The point of the video is to explain to people what the cause of the condensation.. Read some of the comments, people think that it can just be cleaned.
Window and Door Parts Ireland ok Karen
@@PaddysDiy Yes exactly, thanks for posting this as I'd always wondered if it was possible to fix my old windows but can now see that would be a waste of money, half of the hinges are damaged anyway, so new windows in lovely french gray one day :-)
The only thing I can think of is to use a heat gun from the outside? it wont remove stains, but perhaps it can evaporate the water ?
The sun will warm up the moist air and it will evaporate. The reason why it fogs up and looks wet between the two panes, is because the evaporated moisture can't get back out and re-condenses when it gets cold. So unless you keep the temperature all the time above the dew point it won't work I'm afraid.
@@PaddysDiy damn just had a physics lesson 😢
I don’t understand why you can’t remove the window and then glue it back. Am I missing something obvious? If the glass is still in good condition then why do I need to replace it?
i guess I'll have to make a video explaining why
Cool thanks
Can you advise rough cost to replace one of these panes? I have 5 panes in my bay window and all have misted up. I don’t want to get ripped off.
He's never going to answer. It's a hell of lot more than it's worth. I plan to reseal mine because it's just grunt work and not worth the tens of thousands a crooked glass company will charge. I'll learn along the way or fail, but I'll try. Suggest you do the same.
@@lindahickerson4658 I couldnt agree more! Our pvc is in great condition, we had two companies out both said we needed new windows complete! Rip Off Britain! Im doing mine this weekend & may actually even produce a video to help others!
Although your video is very informative, and to the point - the issue for most of us mere mortals is the companies ive dealt with have both told me i need new windows complete! They will not just replace the glazing units & seals! The one was the company who we bought the windows off originally! I had forgotten but my wife picked it up when she saw the paperwork!
You have 2 scenarios. Either your going to the wrong companies, who are just trying to sell you new windows or you are going to the right companies who are being honest with you and telling you your money would have better value spent on new windows.
You need to determine yourself whether its worthwhile to replace the glazing or the whole windows.
Is all or nearly all your double glazing fogged up? How old are the windows? Are they energy efficient? Some of the things to consider
@@PaddysDiy Thanks for your reply, I think it was the wrong company trying to sell us new windows, Neither one even took ay trims out or anything to look. 8 Years Old our windows are, we have a large glass supplier near us and i went there, the chap i saw was soooo different to the 2 window firms, He said they could make the units up for me to instal, and they would be filled with Argon (They make all the glazing for local Window Companies) & they could deliver. He also had the same of a glazier who would be able to do it and replace the black seals too! So I called him and hes replacing the glass in the big bay window which is 2 big units and 5 of the other smaller windows for £570!! We are delighted, glass on order and he will have a big tip!
@@markc1844 That's great to hear. Sounds like a very reasonable price too. Happy days
Mark C;
Just curious how they turned out and after a year how are they holding up?
Thinking of replacing our old bay patio cover 5 double panes.
I have 4 true seasons, just cleaned yesterday (no rain….they looked better but between the glass is uglier than what shows in the video.
Hope you see this message as I’m curious to if your happy with replacing yours and if the company suggested any maintenance tips to keep this from reoccurring???
@@tinaknutsen Hello Tina, we did find a company to replace our sealed units & seals in the end! The companies that tell you you need whole new windows are talking a load of Bull! The glazed units are a separate item to the window, they can be made for any size. Ours were complicated somewhat in the fact the trims had been siliconed in due to our burglary , however they done a great job. The new units were clearer and keep the heat in better than the older units. I was going to replace them myself, however decided to have it done, as they also took all the old glass away. There is no maintenance really, rubber is bonded to glass to make the units, glass and rubber expands when it gets warm, therefore failure in many years is inevitable. Any other questions please don't be afraid to help, regards Mark.
Do you think if someone breaks your window glass the insurance company will replace the complete window
No they won't. They'll pay to replace the broken glass
So in essence would this make the double glazed glass be as energy efficient as a single plain of glass
If the space between the two panes of glass were filled with argon gas, there would be a reduction in the thermal performance. If the space between the two panes were air filled then there would be no change in thermal performance. It's still air between the two panes even if it's moist air
@@PaddysDiy thank you
If the seals had gone would this likely cause more condensation on the inside glass. Thanks again
No it wouldnt effect anything on the inside. Condensation on the inside surface is just a problem this time of year no matter how good or bad your windows are. The less thermally efficient they are the worse the condensation will be
I thought the space between the windows was filled with some sort of gas that can't hold moisture.
No just air in most cases. Argon gas in newer windows. Its the desiccant in the spacer bar that absorbs the moisture
@@PaddysDiy Thanks.
Bitter truth
Unfortunately, I live in a state where the government interferes to the extent it is actually cheaper to not fully replace them.
Silica Gel desiccant can be reused by heating on a tray in your cooker.
Reuse up to 100 times
It's getting it out and back in the double glazed unit is the problem
I got this from within a few weeks of new double glazing
Contact the company that fitted them. They'll be under warranty
@@PaddysDiy Well in warm weather patches disappear. When he came out the mist disappeared but when the cold weather came the mist was back.
@George Christoforou that's how it starts. Go back to whoever fitted them. They will be under warranty
so ... it cant be fixed ? !!
Exactly
Heartbreak hotel in here
Great, my 2 year old window needs to be replaced.
If your windows are only 2 years old they're definitely still under warranty. Contact the company that fitted them
Why the video? You could have said "trust me, just buy another window".
Would you go buy a new car if you got a flat tire? Why would you buy a whole new window when you could replace the section that needs replacing.
The point of the video is to explain to people what the cause of the condensation.. Read some of the comments, people think that it can just be cleaned.
@@PaddysDiy Now, I'm confused. It sounds like you said just buy a new window in the video.
@@tonyborders7108no i didn't say to replace the window in the video. I said replace the double glazed unit. The double glazed unit is not the whole window. You could have multiple double glazed units in one window. If one of them has condensation between the panes, just replace that one
@@PaddysDiy Thank you for the reply. I appreciate your video and the explanation of what causes the condensation inside.
@@tonyborders7108 Thanks for the comment
Give me one good reason why you can't simply separate the panes (or at least one of them) from the hollow center channel, refill the channel with new dessicant, then reattach the pane(s) to the channel, seal the outer edge, and put the window back? Why do you think the glass and channel need to be scrapped? Talk about wasteful and needlessly expensive...
Sounds so easy doesn't it, take it out, split the glass from the spacer, replace the desiccant, clean the glass and re-glue the glass back on.
Do you realise how long it takes to do that? An absolute age to do it properly. I would be surprised if there is a glazier that even provides this service. If there is, then they have absolutely no value for their time or are charging way more than what it would cost to just replace it. I'll give you a bit of information. When you're hiring any trades person to do work for you. You're paying for their time. From the time they get into their van to drive to you, they are on the clock. So the shorter the amount of time to complete a job, the cheaper it will be. Replacing the fogged double glazing is going to be WAY quicker than what you're suggesting. Which in turn is going to be cheaper.
If you're doing this job yourself that's fine. By all means go ahead if you have the time to do it. But there is absolutely nothing simple about what you suggest. Do you realise how difficult a job it is to do? And dangerous even for glaziers who know what they're doing, let alone a DIYer? I know a glazier who was splitting a unit to use one of the panes of glass. Knife slipped while cutting the glue, glass broke and went straight into his hand. Five hours in a&e and eleven stitches.
How is it wasteful? Glass is probably one of the most recyclable materials in the world. It's just melted down and made into new glass. All the old glass I replace is separated into a skip and sent to be recycled. I'll tell you what's wasteful is the time anyone wastes trying to reseal or repair fogged double glazing. And the time reading your comment and thinking you know what you're talking about.
Anyway, I have to go. I need new tires on my car, but it's too expensive to get new ones, so I'm going to rethread them myself. Don't know what I'm doing but what's the worst that could happen eh? 🙃
@@PaddysDiy omg that response was so funny 😂 I understand how the initial commenter feels.
Us regular folk are just trying to save money and being highly suspicious of tradesmen comes with that territory. But thanks you made a great vid with clear explanations 👍🏾
best of luck with that ! the inside of the glass is normally coated with a metallic oxide coat ,if you try to use vinegar or alcohol to clean you will ruin it ,it will look like an oil slick and lose half the thermal efficiency
My parents entire house is double panned windows. F me.. they all are doing this.
I never hated a person more that I've never met before then the guy who built the house with his own plans. It is a money pit and guess who has to fix/replace this stuff. Me.
Is there another solution instead of replacing every single one of these? For my sake lol.
In my experience trying to cut corners to save money usually ends up costing more
Tint those windows withe film
@@JosePerez-ok5rd what will that do with window condensation in between the double pane glass?
@@CoD_Maj3st1k It will atleast cover it up and hide it if the person cannot afford to replace all of the old windows.. its ugly! I have this problem too, and I just cannot afford to replace all my windows, so I am having to cover it with window tints aswell, its effective though, hides it very well
Double Glazing is overrated, in the past the older homes had single glazed windows, when did you ever have to replace a window? Never - unless you hit the cricket ball through it! now the council make it mandatory in new homes, go figure, 2 lots of glass and the machine to make them works out to over three times the cost of a normal window pane. They warrant this by saying your heating bill will be less!! You would have to live until you're 300 to recoup the cost of the dbl glazing then doing it again after 10 or 15yrs!
Double glazing is worth every penny, it's good insulation, and very good for noise reduction, I would hate to have single glazing.
@@MrUniman609 Double glazing is only marginally more insulating than single. Rarely worth the money and replacement windows always look like anachronistic crap on an older home. Make sure your single glazed windows have intact glazing, not cracked or missing. Use a top-notch glazing compound like Sarco Dual Glaze, not DAP/crap.
@@uncurlydiykeratin7860 I Don't work on windows for a living, but in my experience, layering up a clear piece of acrylic to create an air gap (for making 3D printer enclosures), greatly decreases the rate of heat loss with each successive air gap that is introduced. You do have to use a good sealing compound to prevent humidity from condensing on the inside of the panels, but it is more than worth it to layer up window panes whenever you can, and older houses used to do this rather simply by spacing their windows with a 4-in air gap in between, Although, unlike today, those window panes were often separate and moved independently from each other and weren't really affected by humidity because you could easily open the inner or outer windows as needed. It also made replacing those window panes very easy to do. 😊🌎❤️
Everyone died of hyperthermia in those days because of it
Double pane windows seem like a huge waste of money. Who would buy these if your cannot clean them. All the Windows in the house I bought have crap windows that are dirty in between and the answer is to replace all. Replace with what? I live in a colder climate what’s the alternative to these crap windows
The whole idea of double glazed windows is they give way more insulation than single glazed windows. 3 or 4 more. So if you have a whole house of single glazed windows, the money you spend heating your home is absolutely flying out the windows.
Double glazed units are sealed in the factory the day they are made. They're never designed to be taken apart to be cleaned. They are glued together. Good double glazing that is fitted correctly should last for at least 20 years before they break down and let in moisture. That is just the nature of things. Nothing lasts forever. It sounds like the windows in your house are at the end of their life. So replace them with single glazed windows if you want to live in a freezer. Double glazing is you want to have a good level of comfort or triple glazing if you really want to minimise heat loss.
This video was of no help. Could of just took 10 seconds or less and just tell us best way is to replace it 😑

I havev13 windows' he Obviously does not know how much it cost to replace glass. We tapped on his site to find a much cheaper way out so thanks for nothing
Congratulations on having 13 windows. I'm well aware of the cost of glass, and the cost of new windows. After that you lost me, rest of what you wrote makes no sense.
Don't buy Everest....
I cannot understand why you have made a video explaining the ins and outs only to inform us at the end that we need a complete new unit. You are giving people false hopes of a solution, especially on a site called DIY. My window is absolutely massive what has this problem and I was hoping for a cheap solution instead of paying thousand plus pounds.
The video is to explain why and how it happens, because most people don't know. So they don't go off and waste their money trying to fix something that can't be fixed. You're obviously someone that doesn't like hearing an inconvenient truth. I would suggest you go watch the Disney channel if you're not prepared for the realities of this world.

That was completely rude and unprofessional…shocked
Read a comment that he replied back that he went out of business…I felt bad when I read that, but seeing this you know customer service is lacking.
I watched this video thinking the same thing you commented on….looking for a cheaper alternative.
Stupidest design ever!
what if you use a heat gun ?
It'll evaporate the moisture but as soon as it gets cold it'll condense again
