Handi-Foam® E84 Spray Foam Insulation II-105 is a premium two-component, low-pressure spray polyurethane foam (SPF) designed for professional use in residential, commercial, and industrial applications. This medium-density foam is engineered to deliver superior insulation, air sealing, and sound deadening performance—making it ideal for filling voids, reducing vibration, and enhancing energy efficiency.

Key Features:

• 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: Delivers an initial R-value of 6.6 at 1” and 13.2 at 2”, maintaining strong thermal resistance over time.
• Superior Air Barrier: Achieves 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.
• 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).
