Steel stud framing can be placed in the interior for structural support of drywall. Fire assembles add 1, 2, or 3 hours for how long it will take fire to burn through your walls. Sound assemblies are rated by STC rating, with sound transmission constant for theaters or high-end offices, RC channel for higher STC rating, and hat channel for drop downs in suspended hard ceilings. Insulation is added to soundproof 1 room from another.
Acoustic ceilings are installed so that the drywall and ceiling go hand in hand. You can get several colors, with 2/2 textures and 2/4 grid ceilings. We also have second look grids, regular tile, radar tile, and vinyl tile, with clean room sound assemblies.
