Handi-Foam® E84 Spray Foam Insulation II-205 is a low-pressure, two-component, medium-density SPF system designed for professional use. It delivers top-tier thermal insulation, air sealing, and structural reinforcement, while meeting ASTM E84 Class 1 (A) fire ratings.

Key Features & Design

• High Thermal Efficiency: Exceptional R-value of 6.6 per inch (initial), reducing to 6.1 aged — ideal for enhancing energy efficiency in residential, commercial, and industrial applications.
• Durable & Reliable: In-place density of 2.11 lbs/ft³ and >90% closed-cell content ensure robust insulation with excellent resistance to moisture, air infiltration, and structural movement.
• Quick Application: Fast tack-free time (30–60 seconds) and cuttable within 10 minutes. Designed for ease of use with controlled expansion and consistent coverage.
• Versatile Use: Suitable for filling and sealing voids of various sizes, dampening sound, and reducing vibrations in wall cavities, crawlspaces, rim joists, and more.
• Safe & Code Compliant: Meets fire performance standards (ASTM E84 Class A), with low VOC emissions (37 g/l) and excellent fungal resistance (ASTM G21: No Growth). Chemically inert when cured and safe for use around wiring, PEX, PVC, and most common building materials.
