SealTite PRO One Zero is a two-component, medium-density, spray-applied polyurethane foam with an Ultra-Low Global Warning Potential. SealTite PRO One Zero complies with all state environmental regulations and is free of hydrofluorocarbons (HFCs) or flammable blowing agents. Specify it for use in lieu of more traditional forms of insulating materials such as fiberglass, cellulose, or other loose fill products in exterior wall cavities, vented attics, and unvented attic assemblies. SealTite PRO One Zero can also be applied as continuous insulation to above and below grade exterior walls of commercial buildings to reduce thermal bridging while eliminating the need for any additional air, water, and vapor barrier products.
