Deck - Diviny Lam Sched?

[ElBichoMalo]

With 3/8" divinycell core material, how much glass is enough? I glassed the bottom of the dininycell with 1 layer 1708, and planned to "glue" that down the what's left of the old glass (there will be some gaps with no old glass). I wanted to glass the topside after the core is all down, filled, etc. Was thinking two layers 1808 and maybe some 1-1/2 or something.

I know the sandwhich construction gets its strength from both sides of glass, so I know it won't be solid with one side glassed, but it is flimsy. I don't want to find out later that I needed more glass on bottom.

All the old posts I found in search were plywood. Anyone with experience or thoughts on this?

Thanks,
Evan
