We have double pane windows in our almost 4 year old house. The inside
of the window has lot of condensation and water drops forming and
collecting on the window sill. Is this normal? My homeowners manual
says that this happens "due to good insulation" and it's not under
warranty?

Could someone please explain what I should do? Is this because of good
insulation or poor insulation? Is there anything I can do to prevent
this from happening?

Thanks.


i've been going thru the same problem for years. we had wooden double hung
windows w/ alum.storm windows. last year we installed Certainteed vinyl
replacement windows, only because i didn't need a permit and that any
rennovations involving new window installation required egress windows which
would not have been an attractive feature or space friendly for our floor
plans in our home. i've found that on extremely cold and dry days, the
moisture inside starts as soon as the sun goes down and that even running
the hot water in the kitchen can cause the windows to start clouding
quickly. i've resorted to keeping a couple windows cracked open slightly
throughout the house and try as hard as i can to keep the humidity level
below 35% (very difficult) and bumping the heat to 70-71 deg.F from 5pm to
about 10:30pm. on cold and rainy days, there is zero build up or when the
humidity level outside is great than the level inside the house. i also
found that ceiling fans in reversse mode help rather well too. on nice days
don't be afraid to open t he windows and let some fresh air in.

good luck,.....
