Johns Manville Formaldehyde-free™ Fiber Glass Insulation JM FORMALDEHYDE-FREE ™ FIBER GLASS INSULATION JM Formaldehyde-free™ fiber glass building insulation offers superior thermal and acoustical performance —and it improves indoor air quality because it's made without formaldehyde. Why is that important? Because the U.S. Environmental Protection Agency (EPA) recommends limiting exposure to formaldehyde as much as possible, and the California Air Resources Board, a division of the California EPA, recommends that homeowners, builders and architects use building materials and insulation made without formaldehyde when building a home or remodeling. JM is the only company in the industry with a complete line of fiber glass building insulation made without formaldehyde. Visit specJM.com for more information PRODUCT DESCRIPTION Johns Manville ComfortTherm poly-encapsulated thermal and acoustical fiberglass insulation is lightweight and made of long, resilient glass fibers bonded with an acrylic thermosetting binder. ComfortTherm is wrapped in plastic for more comfortable installation with less itch and dust. The product is available with a vapor-retarder plastic facing, and also with a plastic facing that does not act as a vapor retarder for use in hot, humid climates AVAILABLE FORMS • Pre-cut batts - fit standard wall cavities and are faster to install than roll products • Rolls - can be cut to fit any size wall cavity and installed in any part of a building—especially usefu for long, unobstructed areas such as attics or crawl spaces. ComfortTherm insulation carries a Class A rating (ASTM C 665) for low flame spread and has been classified FHC 25/50 by Underwriters Laboratories, meaning it can be used for some exposed (not covered by gypsum wallboard) applications where permitted by the local building code. See National Evaluation Service, Inc. (NES) Report No. NER-549—copies available upon request. Under some conditions, even low flame spread material can burn at a slow rate if exposed to an open flame or other heat sources. Do not use ComfortTherm insulation where encapsulation film will be exposed to sunlight or mechanical abuse • Wood frame construction - residential homes and light commercial buildings • Metal frame construction - commercial buildings • Pre-manufactured homes - modular or manufactured housing • Suspended ceiling systems - sized to fit above 2' x 4' (0.61 m x 1.22 m) ceilings • Interior wall sound control - interior walls and floor and ceiling assemblies (for sound class ratings for wall assemblies, see the appropriate STC values data sheet for either steel or wood framing) • Re-insulating attics (R-25 only) and crawl spaces • Back-fill above suspended ceiling systems ComfortTherm batts are sized to fit standard cavities. You can cut JM ComfortTherm insulation easily with an ordinary utility knife to fit nonstandard cavities, and install it by simply pressing in place between studs or joists. You can secure the insulation by stapling the flanges to wood studs. ComfortTherm is also available in a reverse-flange underfloor configuration with the vapor retarder toward the floor Note: In colder climates, 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. The plastic facing of standard ComfortTherm is a vapor retarder. In predominantly hot, humid climates, many codes make vapor-retarder use optional. ComfortTherm with a non-vapor-retarder facing is available for these areas. Check your local building code for vapor-retarder requirements ComfortTherm insulation is compression-packaged for savings in storage and freight costs RECOMMENDED STORAGE AND TRANSPORT Store insulation indoors. Keep insulation clean and dry at all times. When transporting, cover completely with a waterproof tarpaulin as necessary Thermal and Acoustical Fiber Glass Insulation PERFORMANCE ADVANTAGES • Improves indoor air quality - because it's made without formaldehyde • Poly-encapsulated - wrapped in plastic for cleaner, more comfortable installation with less itch and dust • Thermally efficient - provides effective resistance to heat transfer with R-values up • Acoustically efficient - reduces transmission of sound through exterior and interior walls Specification Compliance. ComfortTherm insulation can be left exposed where building codes permit. • Effective at controlling moisture - the plastic facing is a vapor retarder that resists water vapor transmission. ComfortTherm is also available with a plastic facing that does humid climates • Noncorrosive - does not accelerate corrosion of pipes, wiring or metal studs • Mold-resistant - does not support mold or mildew. Does not supply a food source for • Resilient- bonded glass fibers will not pul apart during normal applications and resist settling, breakdown and sagging from vibration • Flexible - forms readily around corners and curved surfaces.
