JM Corbond 2.8
JM Corbond® 2.8 closed-cell spray polyurethane foam (SPF) is a premium, two component, 2.8 pcf insulation system designed for applications such as storage tanks, agricultural and other Class U buildings, underground, and geological operations. Its high compressive strength and outstanding dimensional stability, superior thermal and moisture performance, and exceptional sprayability and adhesion make it an ideal choice for situations where a high-performance foam is paramount.
ADVANTAGES:
Complete Coverage: Expands and adheres without shrinking or settling.
Energy-Efficient: Reduces air and moisture infiltration.
High-performance Foam: High compressive strength and outstanding dimensional stability.
Moisture Performance: Resists mold growth; meets current vapor retarder codes.
