What causes the moisture in between my double pane glass?
Can the water deposits be removed by cleaning between the glass then reinstalling in the window?
Also once the sealed unit has broken the seal and you see the first signs of moisture it is too late. Once the units seal has been compromised the chemical moisture absorber or chemically called “molecular sieve” has done all it can do. Much like a sponge it will collect all the water to a point then it just can’t hold any more and at this point the chemical is forever dead. To try to separate clean then reinstall is a waist of time and you will again start seeing the signs of moisture almost immediately or when the next rain storm comes.
If you fail to fix the problem though the unit will eventually get worse with time to the point that you will not even be able to see through it
Factors that can cause the unit breaking its seal
… The glass is installed into the frame of the window from the outside allowing water to reach and set at the bottom of the seal for days after a good rain. Water sprinklers contribute to this problem than rainy days.
… The seal was not incorporated on to the unit properly from the day it was fabricated at the factory.
… If what is called “Hot Melt” is used at the factory the hot melt could have been applied to cool or to hot making it not seal well to the glass.
… The factory had a bad mix of sealant from their supplier. This is more evident if a lot of units go bad soon after installation of the new windows.
…Chemicals such as oil, WD-40,or acidic solvents reach the seal.
…Small unseen cracks in the glass. It only takes a pin size hole to break an insulated glass seal.
…Bathroom windows tend to get a double whammy from the shower and the outside elements.
