Comment,
It is our cold damp climate is where bees benefit most from an insulated
hive top.

Try putting the insulation UNDER the inner cover. Or, better still,
throw it away and use the insulation year around.

It's been 25 to 35 for over a week and 45 today. Last summer I made
insulated covers per David Cushman's directions. I went out three
different times during this period. The lids are dryer than I have ever
seen in this kind of weather.

The space between your inner cover and the insulation is not heated as
much as the hive space by heat loss from the cluster. Therefore the
water is condensing there. It is not condensing under the inner cover.
Water does not condense on the insulation or an insulated cover.
