Why Thermal Pane Windows Fail
All insulated glass units (double pane thermal windows) eventually fail. Poor caulking, rotting frames, house settling, improper installation are chief among the many reasons windows fail, but the primary cause of window seal failure is a process known as “solar pumping".
Most people don’t realize that thermal pane insulating glass units are not completely airtight—if they were, they’d explode! When the sun's rays hit a double pane window the air inside heats up significantly, (think of your car on a hot day!) causing the sealed window unit to expand and pushing air out through the semi-permeable seals. At night the window cools and contracts, drawing in air— and humidity— with it. Every day, year after year, this expansion and contraction occurs, drawing moisture into the space between the two window panes.
Window manufacturers expect and plan for solar pumping. Built into every dual pane window frame is silica desiccant to absorb the small amounts of moisture drawn into the window. The desiccant, however, has a limited lifespan. At some point it has or will have absorbed all the moisture it can hold and that is when a misty fog and moisture cloud your glass window panes. From this point on the window begins deteriorating rapidly. If left untreated, the trapped, silica-laden moisture quickly corrodes the inner window glass surfaces, eventually leaving mineral deposits and a permanent white silica haze. Once this has occurred the sealed window unit is no longer repairable.
So don’t hesitate! As soon as you see fog or moisture inside your thermal pane windows, contact us for a free estimate. The longer you wait, the less chance we have for a successful repair! In fact, if you've already had a number of your windows fail we suggest you consider our Preventative Program. We can re-engineer your windows to be sure they never fail at a much lower cost than repairing them and save you even more money.
