A method of forming a polymeric vacuum insulation board is provided, the polymeric vacuum insulation board including a plurality of evacuated, closed-cell pores therein. In one embodiment, the method includes intermixing a polymer with zeolite particles that contain water and extruding the resulting composition under high pressure. During extrusion, water in the zeolite particles evaporates and creates a porous, closed-cell microstructure within a polymer matrix. As the polymer matrix cools and solidifies, water vapor is reabsorbed by the zeolite, which at least partially evacuates the closed-cell pores. In another embodiment, the method includes intermixing a polymer with expandable graphite particles and extruding the resulting composition under high pressure. During extrusion, the expandable graphite particles define evacuated voids.
