The hangar is at Bremerton. It has about 6 inches of insulation on the
ceiling. One wall is on the outside end of the hangar row and has a fire
wall on that side. Just metal is between the individual hangars.

Where are you in the northwest?

I assume that you have a metal roof. It needs to be insulated. My rented
hanger has an uninsulated metal roof. When frost or snow accumulates on
the roof, then is warmed by the sun: drippy ceiling. Conversely, my shop
building at home has a metal roof with 2 inches of fiberglas insulation:
No drip. No wet insulation.

This causes a huge amount of water to condense in my hangar. The floor
will have 1/8 inch of water on it. This has only happened once in 5
years. But today I bought a couple of big fans and plan to cut holes in
the hangar door and continuously vent with the fans.

Do you think I should blow air in, or out. Or should one be in and the
other out. Or is this just a dumb idea and something else would work much
better. The builder of the hangar did not consider condensation and there
are no roof vents.
