It is often said that a sealed unit has failed & gone misty”, This means that a fault, and it may only be a pinhole to start with, like a small puncture, has developed somewhere in its perimeter, and moisture is getting inside and between the two panes of glass. At different times of the year there will be different amounts of moisture in the atmosphere, and even in the hottest of balmy summer days the atmosphere that we breathe has a moisture content (humidity).

With changes in sonic and atmospheric pressure being put upon the ‘sealed’ unit, moisture will be drawn in to mix with the otherwise arid interior of the unit through this breach. As temperatures change the moisture will condense into a liquid, which will continue to build up and up, as the liquid cannot escape anywhere as easily as the moisture that is being drawn in. of water laying at the bottom of them because the unit is acting like a tank!
When sealed units are manufactured they are not designed to be taken apart again in the future, and therefore in practice they cannot be economically cleaned and put back together. When a sealed unit has failed it will need replacing, and the old glass is usually just scrapped. We undertake to remove and replace these type of faults even if the product was supplied by someone else. |
