A family of acoustical ceiling panels for schools, offices, hospitals and other public buildings provides for one consistent look throughout the building while yet provide a range of desired acoustical performances. The family includes a group of substrate mats of a bonded mixture of mineral fiber, glass fiber, and bi-component fibers. Each mat is chosen from a group including a thickness of ¾'', 7/8'' and 1'' depending upon acoustical performance. The group of substrate mats all have an exposed surface chosen from a group including fine texture, heavy texture, medium texture and light texture. The group of mats all have an edge chosen from a group including square, tegular and narrow tegular. |
