What to Use on Double Window Panes that are Fogging?
Removing condensation between the panes is not an easy task. The trouble starts with a small amount of cloudiness that grows over time into a thick blanket of fog. This means that you have a broken seal, which has caused your insulating glass unit (IGU) to fail. So, what are your options?
Vented IGU Units (Window Defogging)
There are companies like Window Defoggers that will come out to your home, drill tiny little holes in the IGU, spray the area with a cleaning solution and install vents into the holes. Some people rant about this type of cure, saying it doesn’t work, while others rave about its effectiveness. Try to find a company that guarantees their work. The cost for this procedure is about one-third that of a complete window replacement.
You can also replace the IGUs. This means that you get to keep your existing sash and frame but must replace the IGU. You can have a glass shop handle the work.
Complete Window Replacement
Keep in mind that window replacement is expensive, but it’s your best option in the long run. You can find a window company that offers a lifetime (or at least 20-year) warranty to get the most out of your investment.
Note: if you choose a window defogger or IGU replacement, your window will no longer be thermal because the insulating gasses (i.e. argon and krypton), have escaped. Hence, the fog.
