Fogged" double-pane window replacement versus "repair"
Atlas Glass Repair does "fogged" thermal window replacement on a regular, almost daily basis. That is to say we replace the "fogged" insulated glass unit (IGU) yet still utilize the existing frame and sash. This is significantly more cost-effective than replacing the window in its entirety. Quite a bit faster turn-around-time as well.
I'd like to take the time here to differentiate our practice of replacing the thermal-pane unit with the recent proliferation of companies that claim they can actually repair the fogged Insulated Glass Unit (IGU) in place.
I must say upfront, that I am somewhat skeptical of the claims these companies make. A quality thermal-pane IGU is a thing of technological beauty. That said, even the highest-quality, most-expensive thermal windows suffer seal failure and can and do eventually fog. Why is this? There are many reasons, but most likely at work is the the process of solar-pumping - that endless cycle of being heated by the sun then cooled at night. The smallest such breach is enough to allow the unit's argon gas to seep out, to be replace by ordinary atmosphere complete with moisture and nasty little microbes.
I do not know enough about the process they use to repair a window that has suffered a seal failure, nor would I be ignorant enough to dismiss it out of hand. But I do know from experience that most first-generation technological advances, while often scientifically sound, tend to disappoint in the results department. One need to no further than first-generation thermal windows which despite manufacturers claims to the contrary often failed within the first five years.
There is no doubt that these fogged window repair companies can get the windows de-fogged in the short term, other-wise they would already be out of business. But what of the longer-term, say five years from now?
While this could very well be the wave of the future, I would recommend waiting until some of the big-boys of industry, companies such as Sears, Home Depot, Loews, etc, who have deep pockets and whose warranties actually carry weight to them,.get involved in the business. If legitimate, this promises to be a multi-BILLION dollar industry. As it stands now, their absence, to me at least, speaks volumes.
