Johns Manville has revolutionized the building insulation industry by introducing an entire line of
formaldehyde-free fiber glass building insulation. JM Formaldehyde-free insulation provides the same
high-quality thermal and acoustical properties as conventional JM fiber glass - just without the
formaldehyde-based binder. Why? Because it's a smart thing to do for our customers and the environment.
Formaldehyde has traditionally been used as part of the binder in fiber glass insulation. Although there
is no health risk with the traditional product, formaldehyde at higher levels may cause irritation and
sensitivity. JM Formaldehyde-free building insulation utilizes an innovative new acrylic binder that
eliminates binder-related formaldehyde emissions during manufacturing and, once installed, will not
off-gas formaldehyde in the indoor environment. No formaldehyde means fewer things to worry about.

DUCT WRAP FIBER GLASS INSULATION
Duct Wrap is sized for use around duct work and other related
applications. Tough, flame-resistant Foil-Scrim-Kraft (FSK) facing makes
it ideal for use around air conditioners, in crawl spaces and behind
stoves and radiators.
Duct Wrap is packaged in 2" thick x 24" wide x 15' long rolls with a 2" tab for
a tight, overlapping seal. Each package covers 30 square feet.
MULTI-PURPOSE FIBER GLASS INSULATION
Ideal for small insulation applications throughout the home, including
around windows, doors, and gaps around air conditioners, outlet boxes
Each 2" thick x 16" wide x 48" long sheet fits a variety of smaller
insulation applications. It is unfaced and cuts easily with a pair of
scissors or knife.
Specialty insulation products are packaged in plastic-wrapped units.

Fiber Glass Insulation" or "Johns Manville Multi-Purpose Formaldehyde-free Fiber Glass Insulation."
Formaldehyde-free Duct Wrap Fiber Glass
and Multi-Purpose Fiber Glass
• Formaldehyde-free-will not off-gas
formaldehyde in the indoor environment.
• Fire-resistant and Noncombustible -
(see Specification Compliance).
• Noncorrosive - does not accelerate
corrosion of pipes, wiring or metal studs.
• Durable - unaffected by moisture, oil,
grease and most acids. It will not rot,
mildew or otherwise deteriorate.
• Resilient - bonded glass fibers will not
pull apart during normal applications
and will resist settling, breakdown and
sagging from vibration.
• Flexible - forms readily around corners
and curved surfaces.
LIMITATIONS OF USE
