Question: Is it possible to “defog” a double-paned window instead of replacing?

Answer: Yes. Windows are a real big deal here at About Home Renovations. Replacement windows are expensive. It’s like the window industry wants to make sure that you take out a second mortgage just for new windows. Why must the answer to all window problems be to call up Pella, replace every single window in your house, landfill 25 windows, and go broke in the process?

Because it’s not the only answer, and there are 4 alternatives:

  1. Replace a broken pane of glass, in single-pane windows. Easy enough to do with a few tools from your local hardware store, and they’ll cut you a pane of glass to size, also.
  2. Replace a double-paned window–just the glass part.
  3. Replace the entire window yourself with a replacement window — not advisable, but it can be done.
  4. Defog the window.

Window Defogging Industry

Yes, window fogging is an industry unto itself–mind you, a small industry. It’s more prevalent in areas where double- and triple-paned windows are common.

Companies like Window Defoggers bore tiny holes in the IGUs (insulated glass units), spray cleaning solutions inside, let the solutions dry up, and then install vents in those holes.

Holes in Your Windows

Don’t be alarmed by the holes in the IGUs. First, these are tiny holes (2mm). Second, your insulated glass units never were completely air-tight in the first place. Surprised?

Don’t be. Your sealed windows have always had venting properties. There is no way that 100% sealed glass units would stand up to the pressures of solar heating and subsequent cooling. You mean to say that the Pella salesman didn’t tell you that?

Lost Krypton and Argon Gas

One caveat to all this. You may ask, “What about my nice expensive Argon or Krypton gas?” Well, that Krypton gas goes the way of Superman…up in the air and away. Never to be seen again.

Personally, I have always been dubious about the value of those gases. Do they slow the transmission of energy? Yes. But Argon and Krypton have become almost like “voodoo” sales language, whereby the big window companies try to spook you into these upgrades or else.

Anyway, rant aside, Window Defoggers quite fairly points out that by the time your window gets fogged up, the seal has already failed and the gas is long gone. So, the window defogging (and drilling of holes) does not release these gases.
