Exterior walls for hunting box blind?

I’m looking to finish my box blind project. I have the framework (untreated 2×4’s for the box on top of my treated base) essentially done, but I don’t want to fully put it out in the elements until I get the outside wall material on hand.

We have some tin material to use for the roof, but we are looking for something to use for the sides. Treated plywood would be great, but I’m wondering if there is anything else that would keep the insides dry and be cheaper to use. I’m certainly not opposed to oddball or unconventional exterior siding if you guys have any ideas…

I have a few 4×8 plastic-like sign/advertising boards that might do the job, but I don’t have enough to do the whole thing. Know where I might find more??? Any other ideas?? I’ll need about 7 4×8 sheets altogether… 5 more if I use those signs that I have…

Thanks!

I saw an ice house made from aluminum/tin coated styrofoam. I’m not sure what it was called, but I think he got it as scrap from an RV manufacture.

When I built the Ramada Inn for my Dad to stay in, I used 2″ foam and the tin side walls from a swimming pool. Even though it has a tin exterior, the foam really helps to deaden the noise. I made sliding plexiglass windows. Remember to keep water running OUT and down.

we made one 5 yrs ago and just used osb board and put a coat of primer on and then 2 coats of paint and it is still in pretty good shape the roof however we used the same and put a couple of 2x4s on one end to give it a slight pitch and shingled it however it sagged in the middle and began leaking and became a complete mess, we actually just finished replacing it today with rafters and tin
