I was thinking about this problem…
Let's say you have 4 40' containers lined up next to each other. If we cut the sidewalls to walk through, we have the above mentioned problems:
- roof sags; rain on the roof goes to the center of the roof into the cracks perhaps in the house
I'm planning a container house in a very cold environment (though dry) and need insulation on the roof somewhere. That would mean I have to use wood to put a regular type of roof on top with something like fiberglass shingles.
Now I'm exploring the idea:
- There is a crack between each container. Fill in the gap with as much spray insulation as you can reach in there.
- weld a strip completely over the top of the crack joining containers on the roof, trying to make it a continuous weld, so no water (or much air) will leak into the container
- stack a second container on each container
- insulate under the floor of the second one and perhaps have a raised floor
- seal up any cracks with spray foam
- weld another strip completely over the top of the crack on the top containers and maybe on the sides.
- paint over the strip of metal with water proof paint.
- use the top floor like a storage attic, workbench area, or greenhouse
- I'm guessing it's a lot less labor than constructing a standard roof
- pretty easy to do insulation between the 1st and 2nd floors for the living space in the 1st floor
- probably has a cool raw industrial look
- could remodel expand the house into the top floor in the future
- right now I think the cost of containers might be more expensive than standard roofing material, though not that much different.
- I wonder if you only filled the crack between containers with spray insulation and welded a strip with a continuous bead to join containers at the crack how waterproof (or possible) that is.
- The Platoon has an open roof deck. I think the whole drainage scheme probably breaks my budget.
