Insulation - SST Basement Systems
We don't recommend insulating the crawl space with fiberglass batts. Batts will absorb moisture, compress, fall onto the crawl space floor and encourage mold growth. The best way to insulate your crawl space is to install SilverGlo® rigid foam insulation against crawl space walls and TerraBlock™ foam insulation over the floor. Both types of insulation offer high R-value, stability and durability. SilverGlo™ and TerraBlock™ won't absorb moisture, support mold or deteriorate over time.
