Lightweight walls

[GeoDrop]

I just weighed my floor.. it is 73.6lbs. Dimensions are 114"x62". Which, after much head-scratching, comes out to 1.49lbs/SF.

My floor is sandwich construction. 1x3 around the perimeter, a couple of cross pieces, 3/4" pink stuff sitting between two pieces of luan ply. It has a coat of CEPS on one side and a layer of Henry 201 on the other, so this is a "finished" weight.

PS - Google search says that rule of thumb... 3/4" ply is 2.34lb/SF.

Thanks, seem s like the plywood skin sandwich method would probably work great for what I'm planning to do.

Was that 1/4 or 1/8 inch thick luan?

Here is a link pictures of the Bluebonnet Teardrop. I've seen this one in person and it is a very nice build. They used the same glass over foam construction for walls and roof:

Hey that's my Aunt and Uncle! Maybe I need to ask them more questions about the weight of theirs. Since I'm looking to build one in the future to haul behind a Fiero, it'll need to be as light as possible.

I just restarted (or started over) on a tear that I thought was going to be too heavy for my needs. My new floor is all cedar wood as will be the framing for the rest of the tear. Planed the boards for the floor to 1/2 inch which will be a sandwich floor with an inch and a half of insulation (blue board). Haven't quite gotten to the stage to get a weight yet but it is considerably lighter that the beast I had in progress.
