Completely Modular foam board building...(WIP)

[Dropshipbob]

Do all structures made with foam board warp at some point?

I'm in the planning stages for a fairly big building and I was going to use foam board mostly because it was cheap and to cut down on weight. If I tried building it out of insulation foam I'd have to make it even bigger to compensate for the thickness of the walls, which in turn would make it heavier AND it would make storing it a nightmare.


My plan is for a two floor, multi-room building. The footprint for each floor will be as big as a standard sheet of foam board.

Suggestions?

I would suggest attaching it to a sturdier surface in order to avoid the chance of warping. Thin panel of basswood perhaps.

None of the stuff I've made with it has warped and it's been collecting dust for years.

So I might be able to build this big a structure out of foam board and it will be fine?

Depends where it will be I have my stuff in the basement & I'm guessing posterboard wouldn't last to long in the April humidity I will find out soon

Yeah, I don't think I'd waste my time building a diorama out of poster board...unless it was for a school project.

I'm thinking that unless you have some cinder blocks resting atop your foam structure, you'll be just fine.

I was thinking I'd make the base out of the think blue or pink insulation foam, then build the structure out of foam board. I seem to recall seeing a really thick version of the stuff at Hobby Lobby, like 1/4" thick. But even that is too thick for me to use for the walls.
