Spray foam hangar insulation

[Vansconvert]

Does anyone have a hangar insulated with spray foam insulation? If so, would you please share some details.
Thanks

I have my RV-4 in a connected row of 30'X45' rectangular non-insulated metal hangars and the one next to me was spray foam coated about 15 years ago. Every square inch of metal, wood and the inside of the doors has about 2" of sprayed foam on it, and I can say it makes a significant difference in both summer and winter. If I recall, the guy who had it done (not with us anymore), spent around 3-4 K to have it sprayed. It looks a bit odd, but is very effective.

We had it in our hangar in northern Wisconsin. It does make a difference. That being said, it will cover any wiring, conduit, metal, wood, basically anything... Once covered, access in difficult, if not impossible. It also is not a smooth surface, putting any kind of sheet goods over it can be problematic. There are definitely pros and cons to it...

Just finished construction of 50 x 50 with Higher Power 46 x 16 door. After a lot of research I will be having it all spray foamed with closed cell next Monday. All Electrical was completed with conduit ran anywhere possibility of new wire needing pulled in the future. After the closed cell (1? thick) the framing of interior walls will be done with stick framing, and exterior walls will be filled with open cell foam. As a side benefit the closed cell is reported to make the shell of the building even stronger. Local costs of closed cell is running about $1.20 sq. ft. not including costs to paint the foam with acrylic latex.

I will try to update with pictures, and thoughts of the process.

45 X 40 X 16 uninsulated pole barn hangar built in mid 70's, leaked like a sieve, foam sealed up the hangar as well as providing insulation, hangar also does not seem to be as noisy on windy days (every day here in Oklahoma ) cost $4K which was about the cost to put in blanket insulation. Seems to work well but does cover absolutely everything as noted above. I also had the roof sealed as well.

I had my shop done. The guy doing it masked off the doors, windows and also the girt, which I wanted to use as a horizontal shelf. Everything they mask off, though, conducts the outside metal wall temp inside very efficiently. The foam needs to be painted with latex for the local fire code and the white I chose brightens everything up nicely. You can choose the foam thickness and check afterwards by sticking a small drill bit or pick into it in various locations.
Like everything else, you get used to the look.

I would be concerned with fire

I would be concerned with corrosion if covering over metal.

It helps tremendously to take photos of the interior before the foam is applied. This will aid in locating wiring, plumbing, etc. when future work is needed.

We did ours and it?s great. Only bad part is you can?t leave most of the foams natural due to fire codes. You either have to paint it with a special paint or cover it with a fire barrier which can be a layer of corrugated metal or drywall.
