Insulating cabin floor for Alaska cold at the off grid homestead.
Ойын-сауық
We are installing 2” foam board and 3 1/2” fiberglass insulation in the floor for a total of R23 insulation value.
Then it will get 3/4” T&G sub flooring on it.
Who are the "Mitchells In Alaska?" Retired brothers, Tony & Perry. as well as Perry's wife Carolyn and their son Tyler and his wife Ginny + 4 dogs and 2 cats.
What are we doing? We are building an off-grid homestead in the Alaskan wilderness that consists of three cabins. We will clear land, saw our own lumber from trees we cut, and build cabins and outbuildings. We have already built a couple of our outhouses and an outdoor shower, etc.
Currently, we're all sharing one tiny cabin while clearing land and milling logs to build 2 more cabins, gardens etc. It's an adventure most would not even attempt & most think we are crazy for doing. An experience of a lifetime & the biggest adventure we've been on. We're learning many new things along the way as well as applying the skills we already have.
Come along on this adventure with us & laugh at our goofs. Connect with us on Facebook at / mitchellsinalaska

My advice, protect the foam insulation on the underside from rodents and other critters with chicken wire net . You won't regret it. Keep going strong with the build!

Darn good job on insulating the floors. I agree with the wire mesh on under side of floor. You'll be glad you took the time with an air stapler. Be worth every penny of it. Great looking build my friend. Steve

I think I would use a two inch wider rim joist and lay full 4x8 foam directly on your timbers with the joists then attached with hangers or ledger boards to the rims in the normal way. That way it would go quickly as well as eliminating all the thermal bridging going on with the joists. For me I prefer 1 1/8 plywood for the floor. It is tongue and groove as well and eliminates the finish flooring while making a stronger floor system. Just saying....

We skirted with metal
Been there done that. But the only way to get a truly warm floor is in a climate like (Canada) this is an heated airspace underneath. I'd raise the cabin 2-3 feet and close off the crawlspace with heavily insulated walls and put in a space heater that blows air into the crawlspace. Problem solved. Oh yeah and take out the foam from between the joists. It fights against the heat coming through the floor. oh yah #2 throw down 6 mil poly on the ground in the crawl space.

Using a saw for cutting insulation? Why not install Scribfacing Vapor barrier and sag it between the joist, spray foam between, then saw cut the foam flat to the top of joist, then the 2" foam on top of the joist to prevent thermal bridge, use 1 1/8 T&G on top of the 4x8 sheets, and use 2 -2x4's Dbl. Rim Bd. At the edge of the floor screwed down to your joist using structural grade screws? Don't get me wrong, you guys seem to do quality work. But looks like maybe just an older technology form of style, that would not pass Energy Codes in the Lower 48.

P.S. Too late now but I would have raised the crawl space. Seems you invariably need to get under there to work and slithering like a snake is no fun and hard to work in. For a small bit more in materials it makes living in much nicer down the road.

@@MitchellsInAlaska Well my earlier thought was on the height of your room. 10 foot ceiling looks more roomier but you have to burn more wood too since heat goes up and most of it is above you now. I'm in Tennessee so I don't know everything about there, but I have noticed some things about what I've saw on people's houses in Alaska so far. I haven't saw what you did so far, but I noticed everyone pretty much collects water from the roof and has a wood shed. I would personally for functions sake add more roof overhang and store wood beside the house, it's closer, acts as a shield, helps keep house temperature up with less wood as it acts as outside insulation, then you collect more water too. If you put a door on that other room and built out a few cords in size bigger for most of the winter you could just open that door and grab some wood, plus more water collection too. I would stack it just like a door didn't exist there and work my way into the pile over the course of the hard winter. I don't know if any of this helped you at this point or not.
