Also, for your application, i highly recommend you look into building codes and use a non-flammable adhesive. I'm sure you don't want another grenfell tower disaster (they used same polyiso boards as hexayurts). at the least seal the seams and you probably want to add a layer of sheet rock on the inside. With 4" panels and glue you won't be able to kick your way out of a fire and escape the fumes.
