condensation inside house on new vinyl windows

I just replaced all of the windows in my house with high-eff double-paned vinyl windows and have noticed that there is condensation building up along the bottom edge of the windows on the inside of the house.

It has been around minus 15 to minus 20 Celsius (that's Canada for you!) fyi... I have turned off the humidifier as I thought that there might be too much moisture inside the house...It has been off for 2 days now and still there is condensation.

Is this just due to the brutal outside temp?? I thought that it might be a poor seal around a window but every one is doing it (there are around 10 windows).. Thanks for your input,

Your new windows are doing just what they are supposed to do....keep air infiltration to a minimum. Turning off your humidifier is a good first step. There is still a lot of moisture in the house and as long as there is and your temperatures are that low, you will get condensation. If you have bathroom and kitchen fans that vent to the outside, be sure to use them. If it continues and you are concerned about damage to the woodwork, you can get a dehumidifier.

It's the "brutal outside temp". What can you expect with R5 or so windows. We actually have about a half cm of frost on the bottom of the windows - but it was -27C last night. The inside temp here is about 18C with RH of 30-35%.

Don't worry it will be +30 before you know it!

Hi,

30-35% RH for that temp. is way too high humidity. T> It's the "brutal outside temp". What can you expect with R5 or so windows.

Yes. You notice the condensation because air infiltration has been reduce to the point that the condensed water is not dried, i.e., the windows are tight. If you are ok with the lower humidity, then turning it off solves the problem. My wife tries to keep the humidity at around 50 percent and is unwilling to reduce the humidity to reduce the condensation. Anyway, the condensation will disappear as it warms up outside, the sun hits the window, the temperature increase in the house, or air circulation increase. Condensation becomes obvious on our windows when it get to about 10 F, that's about -12 Celsius.
