Accufoam Open Cell Foam is a two-component, one-by-one-by-volume spray-applied polyurethane foam. Accufoam Open Cell Foam is a high yield, low-density, no-mix, spray-applied insulation foam, which contains zero ozone-depleting blowing agents and is designed to provide good thermal performance and a significant control of air infiltration of an air-barrier assembly. Accufoam Open Cell Foam is 100% water blown.
