Double Pane Windows Fogging On Outside

Then you have a revelation.

Double pane windows fogging on outside. There is no such thing as a fail proof thermal pane window. Heat softens or weakens double pane window seals which leads to later moisture penetration and fogging. Double paned windows provide home and property owners with security from outside elements and some degree of protection from breaking and entering. This same fogging can occur on any side of the home but tends to be more visible on the sunny sides because the additional heat from the sun can accelerate the seal failure.

Most window seal failure and window fogging occurs because of seal breakdown and water puddling or other major moisture exposure. Maybe it s happened to you. As the sun hits the window the trapped moisture condensation get released. Wood framed windows tend to last 20 to 24 years if well maintained.

The downside to double windows is that they can be prone to collecting condensation that results in parts of the window fogging up and decreasing visibility. Double pane foggy window repair can be done by drilling 2 small holes on the outside pane of glass. Then glue small plastic tubes in the holes to prevent further moisture from getting into the window. The buildup is a result of aging sealant that breaks down and cracks which allows moisture to enter.

You wake up one morning and notice one of your double pane windows or patio doors is a little cloudy. Luckily there are some remedies to the problem. If the fogging or condensation is on the exterior of the outer pane this is normal and indicates your windows are operating normally. Only explanation i can think of is that the double glazing is falling a long way short of what we were promised and that the cold from the airconditioning is communicating through the double glazing to the outside surface.

Condensation on the inside of double paned windows insulated windows or thermal windows is usually caused by the window seals failing around the window panes. You wipe the inside pane with the sleeve of your bathrobe and the cloudiness remains. Every double pane window eventually fails. Some days and especially at night the cloudiness disappears but then it reappears and over time the cloudy area becomes larger thicker.

Intense heat often because of too much direct sun could be the actual cause in many cases. The reason this happens is because the glass get much cooler at night on the new windows than with the old because the heat is not transferring from inside your house to the outside as readily. This typically occurs in older windows or doors. Also with the sun shining through the glass the fogging can be more visible and readily apparent.

When the sun comes up the warm rays hit the cooler glass causing it to warm up quickly and the surrounding air reaches it dew point causing moisture in the air to. It s not uncommon to walk into older homes and see windows on the sunny side of the home with a glass seal failure that allows condensation and fogging between the panes. You wipe the outside pane and get the same results.
