JM Formaldehyde-free™ thermal and acoustical insulation is made of long, resilient glass fibers bonded with a thermosetting resin. A wide range of thermal resistance R-values is available to provide thermal control for both vertical and horizontal applications. JM insulation is available unfaced or with a variety of facings, including kraft or foil vapor retarder.

Use

• JM Formaldehyde-free™ thermal and acoustical insulation can be used in a wide variety of wood frame, engineered wood and steel frame construction applications, including:
• New Construction: residential homes and commercial buildings interior and exterior walls, doors and ceilings for thermal and sound control, as well as basement wall insulation.
• Retro fit: adding insulation to attics, crawl spaces and above suspended ceilings.

Advantages

• Formaldehyde-free: will not off-gas formaldehyde in the indoor environment.
• Thermally Efficient: provides effective resistance to heat transfer with R-values up to R-49 (RSI-8.6).
• Sound Control: reduces transmission of sound through exterior and interior walls and door or ceiling assemblies.
• Fire Resistant and Noncombustible: see Physical Properties.
• Durable Inorganic Glass: will not rot, mildew or deteriorate and is noncorrosive to pipes, wiring and metal studs.
• Superior Performance: bonded glass bars are dimensionally stable and will not slump within the wall cavity, settle or break down during normal applications.
