SWEATING WINDOW PROBLEM SOLVED!!!!!!!!!!!!!!!!
YAHOOOOOOOOOOOOOOOOOOOOO

I too would get excessive window sweating on ALL windows in my house.

When I built my house I failed to properly apply the house wrap and tape around the windows and all seams. This was allowing cold air to flow around the perimeter of the window within the rough opening. The lose fiberglass insulation I inserted between the window and the Rough opening had little affect. The window would easily get much colder than the inside temperature which would encourage sweating.

Finally I contacted Ken of Ken Spears Construction of DeKalb County Illinois.
He suggested the following.

-Remove the window trim from around the window.
-Remove all of the lose fiberglass insulation between the rough opening and the window and any house-wrap paper which might be in the space.
-Spray Window ”Insulation Foam Sealant between for Windows & Doors” between the window and the rough opening.
-Replace the window trim.

PROBLEM SOLVED!!!!!!!!!!!!!!!!!!!

Hi
We installed several windows in our home and they are sweating. They are double pane hurd windows. Our moisture is only 14%. What else can cause sweating? Can the seals cause it?

Hi Keith,
If the gas logs aren’t vented, that could be part of your problem, since gas generates a lot of moisture when burned. Try the other solutions listed above, such as installing and using fans vented to the outside in the bathroom when showering, and see if that helps.

We built a brand new house less than three years ago and the back side of the house, the windows sweat really, really bad.

Can you help us with what to do. Our house is so very energy efficient that our power bill (total electric) with gas logs only that we only burn in extreme cold, never exceeds around $ 150.00 per month. Heat pump is under the house and is 13 sears. Windows are double pane insulated windows. House is total brick to the top of the house and the house is around 2,500 square feet. My wife and I are the only occupants besides our grandson who my wife keeps Mondays thru Thursdays (2 yrs old). We have asked everyone but nobody seemes to be able to help us.

Thanks for your advice!!

our office is located in Tampa Fl. We have offices along the front of our building with large windows at each office. We have noticed that the wall below the windows are getting saturated. I can only guess that the windows are sweating at times really bad. lately we have noticed that the mats in each of our offices are molding underneath. our ac system shuts down at night and turns on early in the morning. Do you think that this fluctuation of temp could be causing this problem?

We have lived in our home 4 years now and never had a sweating problem until this year. We live in Star Idaho. The only thing that we did differently this year from any other year was that we closed the vents under the house in the crawl space. which is what I thought we were supposed to do in the winter to help cut down on heating costs. Could this be why we’re now getting terrible sweating windows all of a sudden? Or could we have a plugged vent somewhere?
