Johns Manville Closed-cell Spray Polyurethane Foam
Johns Manville Closed-cell (cc) SPF is the premium insulation solution. It acts a a barrier to keep the indoors from the outside climate, creating thermal, air and moisture isolation. Because it will not shrink or settle, its incredible thermal and acoustical performance lasts the life of a structure.
JM ccSPF is a spray polyurethane foam building insulation. The product is generated on site by combining an isocyanate and a polymeric resin through a dual-component proportioner. Fast, easy and adaptable, it can achieve an R-value of 19 in 2x4 construction. JM ccSPF is well suited for residential, commercial and industrial applications. As one of the most advanced insulation solutions, it offers climate isolation between indoor and outside environments.
This system is a sprayable, rigid, closed-cell polyurethane cellular plastic foam insulation designed to insulate buildings. The sprayed product, properly installed, results in a seamless, monolithic and durable insulation fully adhered to the substrate.
- Walls - JM ccSPF may be applied to the exterior or interior of walls in both residential and commercial buildings to a desired thickness and R-value. Suitable substrates include but are not limited to plywood, OSB, any foam sheathing with or without foil facers, rock, brick, CMU, concrete and painted or primed steel. JM ccSPF may be applied to these substrates without studs as well.
- JM ccSPF may be used as a nonstructural thermal insulating material in Types I, II, III, IV and V construction.
- Cathedral roofs - JM ccSPF may be applied directly to the underside of roof sheathing between the rafters to the desired thickness. Traditional venting is not necessary and should be avoided (section 806.4 of the 2006 IRC).
- Hybrid solutions - Combine JM ccSPF with JM Formaldehyde-free building insulation to create a custom insulation solution.
- Application temperature range - can be applied at temperatures between 45°F and 90°F.
- Meets incombustible exterior commercial wall requirements in accordance with NFPA 285.
- Superior moisture performance - resists mold growth and meets all current vapor retarder codes.
