You added insulation and windows to fix a humidity problem? That would
only increase it. Are you sure you have a good humidistat, calibrated,
they should be calibrated every few years. Most purchased are way off. I
just bought a taylor, its 15% off. Take a moist rag wrap around
humidistat for 30 min it should read 94 to 96 , recalibrate if it
doesnt.
Did you put foam sheet insulation, does your house have tyvek . do you
have a condensing furnace. Your house isnt breathing enough its to
tight, you should get a blower door test, infiltration, test. You
probably need an air exchanger to move fresh air. Your new windows,
what brand , low e , argon, dual pane do you vent cooking and showers
outdoors, For now open a few windows, air it out see how low humidity
goes, leave a few cracked open see how much of a difference it makes
Find your true humidity, and get some testing done on air exchange.


the house is a 40 year old ranch and in the attic there was only a minimal
amount of fiberglass insulation so i added more on top of what was there,
nothing excessive. i have forced hot air heat and do not have a humidistat
on it and we re-sided on the rear and 2 sides of the house over asbestos and
went down to the tar paper in the front and used foam board over that then
the new vinyl. the windows are certainteed w/ 3/4" double glazed insulated
insulated units. i've been involved in the glass installation and
replacement field for many years and i've never experienced this. the
wireless hygrometer i have is a decent one which gives within 2% accuracy of
the Relative Humidity that is given from the weather channel and the Weather
bug program i have. how much lower should the RH be in the house than 45%-
50%.

thanks,
