Let’s dive in — see this B1 fire retardant polyurethane foam insulation panel in action. In this video, we demonstrate its self-extinguishing behavior, show how the foil facing creates a vapor-tight seal, and walk through installation details for walls, roofs, and ducts. You’ll learn how the closed-cell structure supports stable thermal performance and moisture resistance, and what to check for sealed joints and a proper vapor barrier. A clear, practical look at real use insights for B2B buyers.
