High Quality Vinyl Windows Are Getting Condensation Why

Just like the dew evaporates off of your car and your lawn it will evaporate off your windows as well.

High quality vinyl windows are getting condensation why.

If there is moist air coming into the house around a particular window that moisture will collect on that window pane first. All 3 of these windows were replaced 15 plus yrs ago. For double or triple pane windows. But new windows often seal air leaks and a tighter house means elevated humidity.

Their old windows didn t do this so the new ones must be defective. High humidity isn t the only reason for interior condensation. Try cleaning the windows. In fact the new windows are performing better than ever before.

As the sun warms up the windows the condensation will evaporate. This even happens on newer homes that are well insulated. Take a closer look at the condensation on the windows. If you live in an old house with equally old windows take note of where this window condensation appears.

If you have this problem the humidity level in your home is probably a bit too high. None of the other windows sweat. New windows are not supposed to get wet inside. All of the others were replaced at the same time maybe 10 yrs ago.

Most high quality double pane windows manufactured today have two perimeter seals an inner seal that resists water aging and corrosion and an outer seal that provides rigidity and strength. The odd thing is the mbr has 2 windows but only the one on the back side sweats. Some windows may have just a single seal. If one seal fails resulting in a broken window seal the other can at least for a while pick up the slack.

3 windows on the back of my house get condensation in the winter which is right now. Condensation on new windows makes homeowners angry. With double pane windows you should be able to sustain somewhere around 50 to 55 percent relative humidity indoors on a 40 degree night and not get condensation on your windows. I am a new house homeowner with what i thought were high quality fiberglass triple pane windows and i too have condensation on the bottom of my windows when the outdoor air temperature is very cold below 0 f and the indoor air temperature about 60 f even though the indoor rh is usually less than 35 because i use an hrv.

If the problem is only occurring on select windows it s possible you have a draft problem.
