High noise reduction coefficient, low density acoustical tiles
Acoustical tile including a dried base mat of: about 70 to about 90 wt% mineral wool; about 5 to about 15 wt% perlite; 0 to about 10 wt% starch; about 3 to about 10 wt% latex; 0 to about 5 wt% gypsum; and less than 5 wt% water. The dried base mat without including glass fibers and without a laminate layer or coating and without perforations has a NRC of about 0.70 or greater, a density of about 10 pcf to about 12 pcf, and a thickness of about 1/2 to about 1 inch. The acoustical tile can further include a back coating at a surface weight of about 5 grams per square foot (gsf) to about 40 gsf to the dried base mat, wherein the acoustical tile has the CAC rating of about 30 to about 35.
