The main purpose of insulation is to cover the space with appropriate material so that it can provide benefits associated with it. The thermal protection results in lowered utility bills, reduced moisture infiltration, and packed surfaces, keeping the environment healthy. While the initial cost of crawl space spray foam insulation may be higher than traditional insulation, the energy savings, improved comfort, and reduced risk of moisture damage often make it a sound financial choice in the long run.
