ABSTRACT:
Two acoustical wall panels are secured together back-to-back to form an acoustical wall baffle installable perpendicularly to a wall of an office space in abutting relationship to the wall, ceiling, and floor. Each of the wall panels includes a fibrous glass board mounted in an extruded aluminum frame and covered on the front and edges with a decorative fabric. Each frame includes a rear mounting foot strip for spacing a wall panel from a wall and enabling the wall panel to be hung by the top frame member on concealed brackets, and a rear groove for anchoring the fabric covering by a rubber or plastic cord. The two wall panels are clipped together at the mounting foot strips of the frames by generally U-shaped metal or plastic strips. On the exposed vertical front edge of the wall baffle, a decorative trim strip is inserted between the two wall panels at the fabric anchoring grooves. The wall baffles are mounted by sliding them onto T-shaped mounting strips adhered to the ceiling and floor.
