Part of LAST-A-FOAM® R-9300 Continuous Insulation Block Series, Precast/Tilt-up Concrete Wall Panel Blocks are made of high-density rigid cellular polyurethane material, which prevents thermal energy transfer between building and ground when installed under load-bearing precast, tilt-up, brick, and block walls. Closed-cell structure is inert and prevents absorption of moisture so it does not rot or dissolve in subgrade applications, or promote corrosion of steel components.
