But it depends on how cold it is outside, how wll the windows insulate, and the temp and humidity inside. Usually this happens if the humidity inside is too high. The colder it gets outside, the lower you want the humidity inside. No more than 50% if it's moderate out, going down to maybe 25% if it's 10F outside. You can find charts online. Also this happens in bathrooms, kitchens, more frequently, because humidity is higher there. If it happens in spots like that after a bath, etc, no big deal. It should not be happening in most of the house. |

Metal frames? Frost on the glass or frame? If you live in a cold climate you should have a good double pane window and you will never see condensation. What do you have? What state are you in? |

What do you have? What state are you in? Even with triple glazed you can get condensation if you have 60+% RH and it's -30 out. Mabee even a bit of frost or ice |

Mabee even a bit of frost or ice Kept my house at 40% to 50% and we had temperatures to about -5 with no problems. My first house did though with old windows. Of course, the OP asked a question and never returned. |

Also depends on the humidity level inside the home. Depends almost entirely on humidity inside the house Not as much with double or triple pane glass windows. Having a well insulated window and higher humidity in the home won't produce as much moisture/condensation than with the same humidity and lower insulated glass. |

Any interior surface of the building that drops below dew point will cause water to condense. http://www.dpcalc.org/ |

Actually, to dew point and glass temperature - but the dew point is STILL relative humidity. If the humidity is low enough you won't get condensation on a single pane window at -40. |

I was implying in a higher humidity home, there would be less or no condensation on a double or triple pane glass opposed to a single pane. But overall, with low humidity, it won't show up as you stated. |
