1/2" Walls

[webbaldo]

I thought someone may have posted something similar but im struggling to find anything in the search,

anyway,

After alot of thinking, im pretty sure im gonna go for 1/2" plywood walls to keep the weight down. Im insulating the roof but not bothering with the walls anymore. To keep weight down i'd prefer to use 12mm (1/2) ply with alu skin instead.

My main question is, would this be enough meat to screw items such as the door piano hinges too etc?

Im not bothered too much about the thickness for the roof edge fitting as im using Aggie's awesome idea of one continuous nailer block from plywood. So in reality for the roof edge ill have the 1/2" wall + 3/4" nailer block

Im just concerned about other items like the doors. And also finding t moulding for the doors which is 1/2 and not 5/8

What are your views?

My tear is 1/2". No problem attaching any thing!

Web.

I have built numerous trailers with 1/2" plywood sides.

BUT!

Don't think it can't be done without insulating???

I glue a "Foam backed Rug" to the inside of my Tears.

Now..whats the "R" value of a "Foam Backed Rug"?? Not a clue!

But whats the "R" value of a sweatshirt...a blanket or a wool coat? Don't know that either.

But they all work! Some things are just not assigned an "R" value because there not associated with insulating.

Covering the inside walls with rug does insulate, makes a nice interior finish, makes it quiet and is an option.

If you use 3/8" (or even 1/8" or 1/4") on the outside, 1" spacers, and 1/8" on the inside you can use 1" foam to insulate it, the weight gain will be marginal, the stiffness will increase significantly, and you'll have 1 1/2" (or so) of "meat" to attach to. Far "betterer" IMHO.
