Easy to edit CSI MasterFormat specification for design professionals to specify sprayed acoustical insulation, applied to wall and ceiling surfaces.
Insulation is used in floor, wall, and ceiling assemblies to reduce sound transmission.
In some occupancies, insulation can be left exposed. Consult the applicable building code to determine if this insulation must be covered with a non-combustible product.
This insulation is available as treated cellulose or glass fibers and can be applied to any solid substrate.
