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.
Features 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, floors and ceilings for thermal and sound control, as well as basement wall insulation. Retrofit: adding insulation to attics, crawl spaces and above suspended ceilings.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 floor or ceiling assemblies.Superior Performance: bonded glass fibers are dimensionally stable and will not slump within the wall cavity, settle or break down during normal applications
Environmental and Sustainability Formaldehyde-free: will not off-gas formaldehyde in the indoor environmentFire Resistant and Noncombustible: se.
Design Considerations Kraft and standard foil facings on this product will burn and must not be left exposed. It must be covered with gypsum board or another approved interior finish. Where an exposed application is required, use FSK-25 flame-resistant faced insulation. In colder climate areas, vapor retarders (whether attached to the insulation or applied separately) are often placed toward the heated or conditioned side of the wall. This is done to reduce water vapor penetration into the wall from the building interior.
