Found biggest air leak in garage where forced air furnace exhaust vents outside. Tough to seal as it goes out at an angle and not create a fire hazard. Local fireplace store had a fireproof insulation.
Using a fabric cover over 4" foam block to seal heat loss through skylight no light in winter any way. Stupid skylights those that leak and those that have not leaked yet are the 2 common types here in AK! Have a drop roof between 2 roof lines
with a skylight. Heat loss in winter melts snow that drips on
deck, house entrance, a real pain in the winter. Insulating skylight keeps snow on roof and ice off stairs.
Lots of heat loss on outside wall plugs and switches which are easy to deal with and find in cold temps. Now trying to tighten heat loss on any ceiling penetrations, light fixtures.
