How to insulate your Quonset hut. Spray foam insulation or fiber glass?

Good stuff! Quonset tips and specialized videos like this will help me to eventually make a move. Thank you.

Nice! I was just thinking about this and here was your video.

Nice job man

I like it.

I've considered the quonset hut, but insulation is an issue and the best solution I could find was hempcrete as metal buildings have condensation issues and hempcrete is especially good at mitigating that and also having anti-mildew qualities. They have only just started growing hemp commercially in the U.S.A., so it is still imported and very expensive. CBD sensimilla crops have started happening which can be doubled for fiber/hurd content depending how they are harvested. Seed/fiber Hemp crops are incompatible with sensimilla crops, but it would be nice to have those too. Hope hemp growing picks up and hempcrete gets cheaper in this country!

I'd like to build a different and quirky DIY tiny home (about 800sqf interior space) in rural central Florida using one these buildings. My 1/4 acre residential lot a 750sq feet minimum primary dwelling. I know there will be some challenges to pass Florida Building codes, in particular getting R-30 ceiling insulation. I know I need to get an engineer to build plans for me, I am wondering... I Think I can use really long bolt screws and floating 1x4 furring's to achieve about 8" of wall/ceiling gap. First wrapping and tape a reflective vapor barrier on the inside finished structure, then bolting on the floating 1x4 studs, stuffing in R30 Rockwool bat insulation and then screwing on 1/4 thick wood panel as my finished wall (no drywall). Any thoughts? and is this something that could pass Florida building codes in Zone 2?

Kyle was the quonset hut galvanized? If so did you have to do anything special to remove it for proper bonding of foam to substrate?

any prep on the metal because of oils from the factory?

Curious on what it would cost to do a 50x50x21 quonset house?

😅 can you color the foam or the fire paint if it's staying exposed? How to you prep it to be a house.

How does the foam hold up to the contraction of the steel during hot and cold temperatures. Is there any concern of delamination. Just a thought....

I am going to be doing something similar in Montana soon. it is for my shop - which I will be living in while the house is being built. Since I will be living in it with my family, would you recommend 4" (r-28'ish) or higher? The area of MT it will be is similar weather to Albany, NY (I lived there for a few years so it is a good reference for me). I have been trying to find something that says what R value I should shoot for, but I can't seem to find anything for quonsets, closed cell insulation, and in cold weather. --Thanks in advance

Did you need to prime the metal first? I hear the galvanized metal needs a primer.

What did the 2" of closed cell cost the hut owner?

How much does it roughly cost to spray foam insulate a quanset, or the cost for the job you referred to here.

Great video! Several people have suggested insulating the outside, and I saw your positive response. So if you do this, do you cover it with something? Seems it would look terrible and not stand up to erosion from rain, wind etc.

2 inches so this must be R15? Do you spray in Vermont.? Thank you . Plus you have a new subscriber. I just looked on Google forget it it's 300 miles away thank you but I will continue to watch your videos

Volume?

What would the r value be for only 2" of spray foam?

Is that foam toxic? Dose it off gas? Will carpenter ants eat it like other foams?
