wrote:
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?

That "due to good insulation" us pure BS. It is not due to insulation.
it is because of the moisture in the air is high enough to raise the dew
point high enough that it is above the temperatures of some part of the
window. The water then condenses on the window.

It may be condensing on the window glass or the window frame (especially
if it is metal and lacks a thermo break as most cheap windows do.

It may be considered the result of cheap windows. If they are metal
without a thermo break then I would say that was the problem.

It may be due to too high a moisture content in the house. It may also
be due to some sort of drape or curtain keeping the warmer room air from
getting to the glass and warming it a little.

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.
