A transparent acoustical sound-absorbing, fire-retardant wall finishing system (100) includes a laminated semi-rigid acoustical planar backer board material (101). A glass textile surface covering (107) is used which includes a decorative woven or flat non-woven face (109) and back surface (111). The flexible surface covering (107) is attached to the laminated semi-rigid acoustical planar backer board material (101) at its back surface (111) so that the face of the material (109) fully covers the backer board material (101) for providing an uninterrupted secondary surface giving the appearance of a finished wall.
