During a recent addition I've found that an open grid box frame on 18-24" centers with two 3/4" cross laminated layers of pink extruded foam is MUCH lighter than the plywood and foam combination. This will hold up to about 40 lbs in a typical 18" box. I'm using 1x3"s for the frame. a typical 2' by 8' section of foam and grid weights about what the plywood alone weights
