Gillfab® 5023A


Gillfab® 5023A is a lightweight and low smoke emission sandwich panel made from woven fiberglass reinforced phenolic facings bonded to foam core.


The panel is designed for use in aircraft cabin interior structures as well as aerospace service carts and trolleys. Panel can also be used for non-aerospace applications where a foam core panel with fire resistance and low smoke emission is desired.


  • Low smoke emission
  • Fire resistant
  • Easily cut and machined
  • Uniform, non-porous facings facilitate the application of paint or other decorative overlays with minimal surface preparation
