I think my concern is what appears to be a wall much taller than a tear. Simply, the forces on a member, like a bean, column, or wall, is proportional to the square if the length. So a wall twice as tall needs to be four times as strong.
I appreciate your dislike of plywood, but it does have some great structural attributes.
1/4" thick strips let into both sides would be stronger than 1/2" on one side, but not the way I would go.
I'll try to reread whole thread and see if something else comes to mind.
Thanks for looking into this.
Would for example routing and gluing 1/4 by 2 inch wide plywood strips on both sides of the foam, in such a way as to mimick classic framing with 1 inch lumber be a possible solution, then attach the strips to this 1/4 inch framework and then encapsulate everything in fiberglass, work ?
The easiest i see if to just glass the foam, attach glassed walls to the cleats and the floor with a 4 to 5 inch glass strip going from the underside of the floor up the bottom of the walls, tying walls, cleats and floor together. Tape nailers with epoxy to the glassed walls and attach the wood strips to the nailers ? Doing it this way would give continuous layer fiberglass. I don't see a difference with a classic foamie and canvas sock method apart from the extra nailers on the outside. The gap between the walls and the strips would mean airflow to dry out the strips for example, and extra insulation.
Important to know as well is i don't intend to put any cabinets higher than waist level making the inside feel as spacious as possible, maybe apart some small shelves higher up.
