Have you ever found that you wake up in the morning with a white fluff between your double glazed windows which looks like cotton wool? If so, you are in good company. This is a rather unusual situation that may raise many questions in the minds of homeowners as to what could be the cause and if there is something wrong with the system. However, there are a number of reasons why this unusual look may be so and it is not as strange as it might at first seem. From water stains to dead insulation, here are some things that could be going on right behind your window glass.
This white residue is probably one of the most frequent issues associated with foggy windows and it is caused by moisture trapped between the glass panes. Double pane windows have a space between the glass panes that is sealed with gas or air to provide insulation and this space can become compromised. At times it does get a little humid and when this occur moisture gets in and cause condensation. This moisture gets trapped and after some time it leads to formation of mineral deposits or may lead to growth of mildew or mold which may appear as a furry substance. However, this situation may not be bad, but it can be an indication that the insulation of your window is no longer in its best state.
Another possible cause of the Leiden dilemma might be decay of the materials used in window construction. The use of spacers in construction of double glazing windows is common and these may include the use of fiberglass to enhance insulation. Fiberglass can sometime come off or start to chip off especially for older windows. In this case, fibers can get out and gather on the space between the panes to create what looks like white substance. If you see this kind of accumulation this could mean that it is time to replace, or at the very least, repair the window in order to regain its insulating abilities.
The fuzz might as well be plant material, including cottonwood seeds or other particulates from plants and other vegetation. Cottonwood trees shed cotton like seeds in white clusters and these may get trapped in window sills or any crevices. If your windows aren’t well fitted, then there is a high probability that this material will get trapped between the panes. While it is not dangerous at all it is a clear sign that the window seals need a bit of attention so that no more debris or moisture can get in.
It does not matter what the reason may be for the white fuzz between your window panes it is generally a clear indication that there is an issue with the windows seal or insulation. This could be due to several factors including; water accumulation, worn out insulation or plant debris and it is more advisable to have it checked and sorted as soon as possible. If such a situation is left unaddressed, it results in poor insulation, increased energy costs, and other dangers such as growth of mold. This can only be done by a professional window inspection in which you will be able to know exactly what has caused the problem and the most ideal way to see that your windows are back to their normal state.
