We can't afford new windows. Carol id caulking and painting. That should limit the damage from mold. What about insulating tape. Is there a good looking white tape we can use or one that will take paint and caulk? |

14 Nov 10 - 03:53 PM (#3032087) Subject: RE: BS: Sweaty windows From: Richard Bridge AFAIK aluminium window frames should include thermal breaks, but even if they do not the loss through frames is fairly low. If condensation is a major problem (1) check air circulation (2) avoid using moist heat (3) use hygroscopic solutions and recycle daily. |

|
14 Nov 10 - 04:41 PM (#3032131) Subject: RE: BS: Sweaty windows From: Q (Frank Staplin) Akenaton and Robert Bridge have diagnosed the cause of the problem. Here in Alberta where it can get very cold and the humidity very low, most people have humidifiers attached to their furnaces. Sweating and ice on the windows is unavoidable if warm moist air is desired in the house, especially if there is a small leak in the double panes. Our water is high in calcium-magnesium; the filters in the humidifiers have to be either cleaned or replaced often, a nuisance. |

14 Nov 10 - 07:57 PM (#3032260) Subject: RE: BS: Sweaty windows From: gnu "When bottled or mains gas is burnt, it gives off water vapour ...moist heat." So, that would be from the hob? I assume the exhausts from the furnace and water heater are vented properly. That being said, there is far more water vapour produced from taking a bath or a shower or from cooking a stew on the hob, which also occur in my house which is heated with electricity. I still don't understand how "moist heat" adds much to the humidity in a dwelling. Perhaps you could edify me. I really would like to grasp this concept in the full. |

14 Nov 10 - 09:29 PM (#3032311) Subject: RE: BS: Sweaty windows From: The Fooles Troupe "sweaty windows" I wondered whether this had anything to do with computers... "moist heat" - Hydrogen from the hydrocarbon fuel combines with Oxygen in the air to burn and produce H2O - water - the carbon -> CO2. Coal or coke fires produce less water vapor than wood or gas fires. The old wood stoves (which vent outside) produce 'dry heat' - they elevate the temperature thus reducing the humidity. Humans need some humidity, totally dry air is not good for us and can promote illness - so one often has some water boiling on the old wood stove. |

The moisture will condense out on any cold surface and aluminium window frames without a thermal break are a disaster. We replaced ours with UPVC. Before we had saved up emough to do that, I wiped the condensation away a couple of times a day to discourage the mould. |

15 Nov 10 - 02:40 PM (#3032857) Subject: RE: BS: Sweaty windows From: Alan Day If the window is cooler/colder than the inside temperature then condensation will form on the windows. Shops have major condensation problems and they have to fix a blower system to dry the moisture on the windows to enable people to see their stock. This problem is not to be confused with double glazed systems that have "Blown" where the seal in the unit is leaking , and moisture forms between the two panels which form the double glazed unit. Secondary double glazing is the best for reducing the problem, but many dislike it for aesthetic reasons. Al |

15 Nov 10 - 03:45 PM (#3032914) Subject: RE: BS: Sweaty windows From: JohnInKansas You could use the method used in air conditioned autos. I haven't checked on recent models, but a few years back whenever the AC compressor was run it held the evaporator at a constant temperature, typically 40F (4C). (Anything colder could cause it to ice up.) If you wanted anything "less cold" than that, the heater re-heated the cold air that came through the evaporator, and/or mixed hot air with it. Since nearly all the moisture in the air that came through the evaporator was "wrung out" and reheating it additionally reduced the relative humidity, the re-heated air was very dry, and (theoretically) your windows didn't fog up. Usually, anytime the defroster/demister setting was selected, the AC was automatically turned on, but if the OAT was below 40F/4C of course it wouldn't run. At temps that low, a relative humidity of 100% is pretty close to an absolute humidiy of "nothing much," so it didn't matter whether it ran or not. So the simple solution is to turn your air conditioner on to wring out the moisture, and at the same time turn on your furnace to warm things up. You should have nice dry air in the house so that the windows won't drip. Just be sure that the condensate drain on the AC doesn't freeze up and drip back inside. John |

16 Nov 10 - 02:54 AM (#3033229) Subject: RE: BS: Sweaty windows From: Donuel Wrap in shrink wrap and caulk repeatedly until sweaty???? I had some success with using those dissicant packs that come in electronic packaging to keep them dry. Put them between the plastic and the glass window. I used the shrink wrap and have taken large foam insulating sheets and made round windows with plastic wrap or plexi glass. Plastic wrap worked best. Light wieght and reuseable for years. Just seal with theclear insulating tape which is great stuff. Using the foam panels with smaller clear plastic windows put an end to the sweaty large window that was near the bathroom door. I had previously used a plexi glass insert but the condensation on the glass part was awful. |
