The higher the STC rating the better the sound deadening ability of the material. (Above party wall STC ratings were calculated according to ASTM E-90 testing for sound transmission loss in double 24” o.c. wood stud walls with one 5/8th inch layer type X gypsum on each side.)
Cotton Armor is an unique 21st century insulation hybrid, which utilizes the ancient insulating and acoustical properties of cotton that is coupled with a proprietary technologically cutting-edge fiber layering process. Because Cotton Armor is made from recycled cotton fibers it is as comfortable, non-irritating and as safe to use as your favorite pair of jeans. Additionally, it is sized for 16" o.c. and 24" o.c. residential and commercial framing, which combined with its unique layering reduces compression, gaps and voids that can significantly decrease acoustical and thermal performance. Cotton Armor blanket insulation is both easier to properly size and to install, than yester-years batts. Consequently, its reduced installation time and enhanced acoustical & thermal performance are welcomed by both installers and building operators.
Even when used in a single wall configuration, Cotton Armor delivers extraordinary acoustical performance:
An R-13 Cotton Armor insulated wall has a 52 STC
An R-19 Cotton Armor insulated wall has a 53 STC
An R-21 Cotton Armor insulated wall has a 54 STC
(Single wall STC ratings were calculated according to ASTM E-90 testing for sound transmission loss in 24" o.c. steel stud walls and one 5/8th inch layer of type X gypsum on each side.)
Established in 1978, Aaron and his son Terry Applegate began manufacturing cellulose insulation out of a small facility in Okemos, Michigan. Today, Applegate headquartered in Webberville Michigan, is the largest privately-owned cellulose insulation manufacturer in the world, and supplies a variety of insulation products throughout the United States. Applegate currently operates facilities in Michigan, Wisconsin, Pennsylvania, Kentucky, Georgia, Louisiana, and Colorado.
