Cotton Armor Blanket Insulation

1. Scope

This specification provides information relevant to the installation of Cotton Armor insulation in attics, walls and floors. Cotton Armor insulation delivers superb R-value per inch, and excellent sound control qualities.

2. Components

Cotton Armor blanket insulation contain 85% recycled content, and is primarily composed of cotton. A proprietary fire retardant penetrates and strengthens the fibers while providing permanent flame resistance. When installed properly and under normal conditions of use, these materials are nontoxic to humans and will not adversely affect other building components.

3. Purpose

3.1 Thermal Insulation

Cotton Armor insulation helps buildings stay warmer in the winter and cooler in the summer by effectively controlling all 3 methods of heat transfer: convective, conductive and radiant, helping your home be more comfortable and lowering your heating and cooling bills.

3.2 Acoustical Insulation

Cotton Armor insulation provides superior sound attenuation to conventional batts, in large part, because it is press fit and has a strong rebound. Both the press fit and strong rebound help to ensure a better seal of the building envelope that minimizes the acoustical shortcuts that are created by less rigid batt insulations. The rebound allows Cotton Armor to fill gaps and voids in odd shaped cavities and around obstacles such as plumbing, air ducts and wiring.

4. Performance Standards

Cotton Armor insulation conforms to the requirements of ASTM Standard C-739. Cotton Armor insulation is tested by independent third-party laboratories.

4.1 Thermal Resistance

Thermal resistance R-values up to R-3.9 per inch calculated using ASTM C-518.

4.2 Non-Corrosive

Cotton Armor is tested and certified to be non-corrosive in accordance with ASTM Standard C-739. The test regimen includes aluminum, copper and steel.

4.3 Fire Safety

Cotton Armor meets or exceeds all necessary fire safety requirements conducted in accordance with ASTM standards:

Flame spread 15 (class A)
Smoke developed 40 (class A)
Smoldering Combustion: <15%

4.4 Moisture Absorption

Cotton Armor complies with ASTM Standards that require less than 15% weight gain under test conditions. Normal relative humidity variations do not adversely affect the insulation.

4.5 Health and Indoor Air Quality

Cotton Armor does not contain fiberglass, formaldehyde or other materials associated with increased health concerns.

OSHA or CAL OSHA carcinogen warning? : No
Contains respirable glass fibers? : No
Contains formaldehyde? : No
Itch? : No

4.6 Other Properties

Cotton Armor passes ASTM C-739 tests for odor emission and fungi growth.

4.7 Sound Control

Cotton Armor is an excellent insulation 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.

R-21 Cotton Armor insulated wall: 54 STC
R-19 Cotton Armor insulated wall: 53 STC
R-13 Cotton Armor insulated wall: 52 STC
(STC ratings calculated according to ASTM E-90 testing for sound transmission loss in 24" o.c. steel stud walls and one 5/8 th inch layer of type X gypsum on each side.)

For party walls:

R-19 Cotton Armor insulated wall: 59 STC
with two layers of Cotton Armor: 62 STC

R-13 Cotton Armor insulated wall: 57 STC
with two layers of Cotton Armor: 60 STC
(STC ratings calculated according to ASTM E-90 testing for sound transmission loss in double 24" o.c. wood stud walls and one 5/8 th inch layer of type X gypsum on each side.)
