8 gal. E84 (HFO) System-8 Closed-Cell Spray Polyurethane Foam Insulation | HAN-P23000

HandiFoam's E84 System8 8Gal HFO Spray Polyurethane Foam Insulation (P23000) strengthens building envelopes by sealing air leaks, resisting moisture, and contributing to fire safety. Classified as ASTME84/Class1 fire rated at 2.5in. thickness, this foam resists flame spread and smoke development under fire exposure. Its density and closedcell structure provide moisture resistance, mould and mildew control, and minimal water absorption. Covering roughly 1,015 board feet in theoretical yield (realistic yields somewhat less depending on application thickness and substrate), the System8 is efficient for midsized jobs, retrofit insulation, crawlspaces, and other cavity fills. The fast tackfree and cure times keep installations moving.

• Achieves approximately R'6.6 per in. of thickness which improves overall insulation value
• It uses an HFO blowing agent for reduced environmental impact and regulatory compliance
• Its closed'cell structure resists moisture, mould growth, and water absorption
• ASTM E84/Class'1 fire rated at 2.5'in. thickness which helps meet fire and code requirements
• It applies between 40°F and 100°F ambient temperature which increases workability across seasons
