Storage / Well House steel door indicates not insulated too well. Where did they miss at the factory?

Out door ambient 29°F / heavy frost - RH 100%. Indoor temperature 44°F - RH 54%.

It is probably insulated, its just more likely that the insulation has de-laminated from that part that is showing. Keep in mind, the overhang will keep it slightly protected/shielded from the North facing ski so not is cold either.

Where it will be warmer (i.e. edges and covered) is where it will be less likely to form dew/condensation.

If I can think to do it , the next time I see that on the door I'll slip my moccasins on and go take some temperatures of the 2 areas. I would think there would be enough significant difference for a cheap General infrared to pick up.

With more info. I believe we can safely say the manufacturer cut corners during the insulation process on all 4 corners + 2 sides + top and bottom, but I suspect it's legal to claim this can be sold as a insulated steel door.
After 37 years it's a little late to claim foul play so I suggest doing some investigation before purchase.:wink2:


Outdoor ambient temperature 29°F, dew point temp. 29 degrees , RH 100%, indoor well house temperature 51°F , RH 49%.

Bottom half of the door gets more battered by heat and therefore expansion and contraction. It is likely the foam has either pulled away along the bottom or shrunk slightly.

After 37 years...you are winning on this deal.

Also...as I said above...the upper part of the door that is shielded from the North sky...will be warmer. The North facing sky actually pulls heat away.

It probably doesn't matter this A M but the door faces east and has had plenty of blistering summer sun in those years. Thanks for the information about shrinkage, didn't know that. That also makes me question what foam insulation does in walls with age. This pic was a recent A M shot and the sun still wasn't quite awake.
