MINERAL FIBER BASED CEILING TILE
An acoustical tile having a wet laid mineral fiber basemat, a non-woven porous fiberglass veil adhered to the basemat and covered with a light reflecting air permeable coating, at least 90% of the weight of the basemat comprising mineral wool and binder, a weight of the binder being less than 1/11 of the weight of the mineral fiber, the basemat having a density of between about 11.4 and about 14.2 lbs/cubic foot, the mineral fiber having an average diameter of between 4.5 and 8.3 microns, the composite of the basemat, veil and coating exhibiting good NRC and CAC performance values.
