Handi-Foam® E84 Spray Foam Insulation II-105 is a premium two-component, low-pressure spray polyurethane foam designed for professional use in residential, commercial, and industrial projects. It delivers superior insulation, air sealing, and sound deadening in a single, easy-to-apply system—perfect for filling voids, reducing vibration, and boosting energy efficiency.

Key Features & Design

• Class A Fire Rated: Meets ASTM E84 as a Class 1 (A) system with a Flame Spread Index of 5 and Smoke Developed Index of 450 (at 2" thickness).
• High R-Value Performance: Initial R-value of 6.6 at 1" and 13.2 at 2", maintaining strong thermal resistance over time.
• Superior Air Barrier: Ultra-low air leakage at 0.003 cfm/ft², making it an excellent choice for air-sealing projects.
• Closed-Cell Construction: Over 90% closed-cell content for maximum moisture resistance, durability, and dimensional stability.
• Low VOC: Emits only 37 g/l when mixed, supporting healthier indoor air quality during installation.
• Fungi-Resistant & Chemically Inert: No mold growth and safe for use around electrical wiring and common plastics (including PVC, PEX, and Romex®).
• Recommended Applications: Wall cavities, rim joists, and crawl spaces; attics and roof decks; around windows, doors, and mechanical penetrations; soundproofing and vibration reduction.
• Installation & Safety: Apply between 40°F and 100°F on clean, dry surfaces. Condition chemicals to 75–85°F before use for optimal results. Use appropriate PPE: certified respiratory protection, gloves, goggles, and protective clothing.
• UV Consideration: Not UV resistant—coat or paint if left exposed.
• Storage & Shelf Life: Store in a dry area, away from open flames and temperatures above 90°F. Shelf life: 24 months (unopened, properly stored).

Engineered for professionals, Handi-Foam E84 II-105 delivers reliable performance and ease of use in demanding environments. If you’re aiming for a tight building envelope, reduced vibration, and quieter spaces, this SPF offers the right balance of fire safety, insulation, and durability.
