Case #345, titled “The Rooster’s lost his head” has a Mr. Fogazio Legano, aka ‘Foghorn Leghorn’ a nickname he picked up in grade school, due in part to his schoolmates from the local farming community having difficulty pronouncing his name, along with this term of endearment somewhat reflecting his large, boisterous manner, waking up to a foggy day.
In actuality, the morning was a little cool, but quite clear, with a bright sun rising slowly over the silos. What fooled Foghorn was the fact the thermal pane glass in his bedroom double hung window had suffered a broken seal, and had basically fogged up.
A thermal pane unit is essentially two sheets of glass united by a spacer, then further sealed with a rubberized type of air-tight band. Thermal pane glass is also referred to as an insulated pane because the space between the two sheets of glass is filled with argon gas, along with a clear film of material (Low-E) attached to the inside panel.
Argon gas is a colorless, odorless, and harmless gas that’s five and a half times heavier than air. The argon’s weight factor is what makes it several times superior to air when it comes to insulating a space. The clear low-E film allows light and some solar heat to pass through, while reflecting the heat provided by the home’s furnace, back into the room. Having both argon gas and Low-E film in a sealed unit is what creates a glass pane of optimal efficiency.
When the seal on a thermal window breaks, the argon gas escapes into the atmosphere, and is replaced with air. On a cool fall morning, this air will condensate in between the panes of glass, causing what’s simply known as a foggy window.
What really upset Fogazio though, was that due to him thinking the climate outdoors was so unfavorable, he ended up binge watching seasons 1 through 8 of ‘The Gilmore Girls’ with his girlfriend Juanita, aka Miss Prissy, basically wasting what was a beautiful weekend.
As a result of this lost opportunity, and with a few other windows in his home experiencing this same condensation issue, Foghorn began ranting and running about the place like a chicken, er, rooster with his head cut off. With his head still in a buzz, Fogazio called the number off a flyer he had seen in the mailbox some weeks before — it simply read as “Freddy’s Fog Removal” specializing in removing condensation from thermal glass panes, just call Freddy, aka ‘fast Freddy’, aka ‘Freddy the fog’.
Within days, Freddy showed up, and proceeded to drill a hole in each thermal pane, followed by the installation of a vent valve to help keep the window clear. This type of venting process, or strategy, can work, and if your goal is simply to have a clear window to look out of, then this is certainly a convenient, and less expensive (at least initially) solution to a foggy window. However, there’s a downside to convenience. The mini spare tire that allows you to drive your car home after a blowout, is convenient, as is using duct tape to hold up a sagging muffler, or having a bag of mixed nuts in your glove compartment, should you get a bout of the hungries. Convenience is good, but it’s inefficient, and only temporary. Without the argon gas, and with air moving freely into the pane, the glass panel has lost 50 percent of its capacity to retain heat.
As the months passed, these re-conditioned windows began to once again condense, along with a few other random panes. After evaluating the situation with Fogazio, it was decided the only two acceptable solutions to his window condensation problem would be to either replace the failed glass with new thermal panes, or in the case where the window was having operational difficulty, replace the window entirely. This way, maximum efficiency and home value would be maintained.
Case #345 closed. Good building.
