So many IG Units have filming, wipe marks, fingerprints, scratches, and many more defective markings "in between" the two plates of glass. These defective units cannot be repaired. They must be replaced. Window manufacturers and sales companies don't even know about this problem most of the time. This is the number one reason why windows MUST be cleaned by a professional window cleaning/consultant before a house is purchased/sold or immediately after a house is built. Forget about scratches and defective/scratch sensitive surfaces;...as I have just said, this is the number one problem that must be addressed when house or store front windows are cleaned. Also this is New England, and IG Units are the most common type of window out there. This is also a problem that no one can blame the window cleaner for. We should do our best therefore to educate our customers about defective IG Units.
IG Units are manufactured in a factory for the window manufacturers. The glass sheets come from the glass manufacturers. Which is also where the hard and soft low e coatings are applied. The glass is cleaned here too. And should be inspected by the IG Unit manufacturer for perfection. But usually is not. The workers in the IG Unit Manufacturing Plant should inspect the glass sheets to make sure they are "good". To make sure they have been properly cleaned and are free from all surface defects before they are used to make the IG Units. They will use spray cleaners and paper towels or rags. The low e coatings will show imperfections much better than glass. Low e hard coats can be cleaned. However low e soft coats cannot even be touched without permanent damage. Soft coats are always intended for placement in between the two sheets of an IG Unit. Hard coats can be used between the two sheets of IG Units or exposed to the inside or outside of the building. The picture below is of an IG Unit with the Low E coating in between. Sometimes however low e coatings are not used at all when the customer is charged for them. Or they are reversed so they are put on the outside. Another mistake. This is a big part of what we offer when we clean windows. And believe it, people do care. When they pay very high prices for the home, or are looking to put the house on the market for a nice price.
Once a low e window loses its seal and develops the effect shown below it cannot be repaired. Further this usually begins very slow and becomes worse over time. It doesn't just remain barely visible. It usually cannot be detected at all if the window is dirty. Once the window has been professionally cleaned it can be detected by the trained eye. Once it becomes worse it can be easily seen by the untrained eye. To reiterate this is what we can offer as NEGSA Professional Window Cleaners.
