THANKS!
The first question is the hardest. You have to decide that one before you start.
I compared my panels to standard ply when I was finished. I think they weighed 1/3 less.
The cost is pretty similar. I used 1/8in luan for the faces which is pretty cheap.
Sandwich walls are more labor intensive and takes some planning. You have to know where things will attach (shelves, bulkheads, etc) before you build your wall. There is an easier way which involves using 3/4in ply as the center structure, but I've heard the the ply isn't actually 3/4in thick where insulation is. One more thing, if you're gonna stick build it, don't use furring strips, they are not 3/4in.
