1. Scope
This specification provides information relevant
to the installation of Mother Nature’s Insulation
in attics, walls and floors using pneumatic
equipment. Mother Nature’s Insulation delivers
superior R-value per inch, exceptional resistance
to air infiltration and superb sound-deadening
qualities.
2. Components
Mother Nature’s Insulation contains more
than 85% recycled, natural cellulose fiber.
A proprietary two-stage process injects dry
and liquid fire retardants that penetrate
and strengthen the fibers while providing
permanent flame resistance. When installed
properly and under normal conditions of use,
these additives are nontoxic to humans, will not
adversely affect other building components,
and actually help create an environment that is
inhospitable to the labeled insects.
3. Purpose
3.1 Thermal Insulation
Mother Nature’s Insulation helps buildings stay
warmer in the winter and cooler in the summer
by effectively controlling all three methods
of heat transfer: convective, conductive, and
radiant. Buildings are more comfortable and
less expensive to operate and maintain. MNI’s
R-factor of 3.7 is a 48% increase over the U.S.
Department of Energy’s allowance of 2.5 R for
loose-fill fiberglass.
3.2 Acoustical Insulation
Mother Nature’s Insulation provides superior
sound attenuation, in large part, because it is
blown or sprayed in. This provides a custom fit
that eliminates the acoustical shortcuts that are
created by batt insulations: gaps and voids in
odd shaped cavities and around obstacles such
as plumbing, air ducts, and wiring.

3.3 Pest Control Insulation
MNI Thermal, Acoustical, and Pest Control
Insulation is a ready-to-use insect control
insulation. The product is tested to help
control the listed insects and is intended to
prevent their infestations in building voids
(attic, wall, between-floors, crawlspace)
where the product is applied. Its effect begins
only after insect contact with the product.
Controls: Cockroaches, Termites (including
Formosan Termites), Ants, Silverfish, Earwigs,
Crickets, Sowbugs, Darkling Beetles, Millipedes,
Centipedes, and Booklice. Not recommended
as sole protection against termites. Use of
this product does not substitute for pre- and/
or post-construction mechanical alteration,
soil treatment or foundation treatment. For
active termite infestations, get a professional
inspection.
4. National Standards
Cellulose insulation sold in the US must
conform to CPSC Standards 16 CFR Parts 1209 &
1404. Mother Nature’s Insulation also conforms
to the requirements of ASTM Standard C-739-
00. Mother Nature’s Insulation is tested only
by nationally certified, NAVLAP-approved
laboratories.
4.1 Thermal Resistance
Thermal resistance calculated using ASTM C-518
is R-3.7 per inch. 4.2 Non-Corrosive Mother
Nature’s Insulation is tested and certified to
be non-corrosive in accordance with ASTM
Standard C-739- 00. The test regimen includes
aluminum, copper and steel. 4.3 Building Codes
Mother Nature’s Insulation, when properly
installed, meets the following building code
requirements for thermal insulating materials:
BOCA, CABO, ICBO, ICC, SBCCI, & the Model
Energy Code.
4.4 Fire Safety
Mother Nature’s Insulation meets or exceeds all
necessary fire safety requirements conducted
in accordance with ASTM standards:
Critical Radiant Flux: >0.12 w/cm 2
Smoldering Combustion: <15%
Flame Spread (ASTM E-84): 15
Smoke Developed (ASTM E-84): 5
Fuel Contribution (ASTM E-84): 0
|
4.5 Density
As tested by federally required methods, the
maximum anticipated density of Mother
Nature’s Insulation after long-term settling of
dry application is determined by ASTM C-739-
00 to be 1.45 lb/ft 3.
4.6 Moisture Absorption
Mother Nature’s Insulation complies with ASTM
Standards that require less than 15% weight
gain under test conditions. Normal relative
humidity variations do not adversely affect the
insulation.
4.7 Health & Indoor Air Quality
Mother Nature’s Insulation does not contain
fiberglass, formaldehyde, or other materials
associated with increased health concerns.
OSHA cancer warning? No
Contains glass fibers? No
Contains formaldehyde? No
4.8 Other Properties
Mother Nature’s Insulation meets or exceeds
ASTM C-739-00 tests for odor emission and
fungi resistance.
4.9 Sound Control
Mother Nature’s Insulation is an excellent choice
for reducing sound transmission through
walls, ceilings, and floors. The following Sound
Transmission Class (STC) ratings demonstrate its
effectiveness in attenuating noise. The higher
the STC number, the greater the reduction in
sound.
Cellulose insulated wall: 44 STC
Fiberglass insulated wall: 39 STC
Uninsulated wall: 35 STC
