AlphaMidnight Ceiling Tiles consist of a 1" or 2" thick 6.0 lb pcf (per cubic foot) fiberglass board faced on one side with black matte material. This solid black acoustical ceiling tile offers a combination of a great acoustical value, economic price point and a unique design. AlphaMidnight Ceiling Tiles offer simple installation since they can drop into a standard ceiling grid while the fiberglass core allows for easy cutouts. These atmospheric tiles are very popular in home theaters and cinemas.
