The material for these two panels are the following? I need the correct material so I can determine the weight.

PANEL-1

2/2 PLY EPOXY/ 7781 GLASS/DIVINYCELL
CORE FLAT SANDWICH PANEL, .375 THK

PANEL-2

HIGH DENSITY PVC FOAM INSULATION, .50 THK

I also attached the 3D models saved in 2017 Solidworks.
