ACOUSTIC CEILINGS
Acoustic ceilings: what to coordinate before installation
Plan acoustic ceiling materials, performance requirements, and installation details before the work reaches the job site.
Begin with the room’s purpose
The ceiling specification should reflect how a space will be used. A meeting room, shared workspace, and busy gathering area can have different acoustic priorities. Share those priorities and the design team’s specifications with the subcontractor instead of relying only on the appearance of a ceiling tile.
Distinguish absorption from sound blocking
Noise Reduction Coefficient (NRC) describes sound absorption, while Ceiling Attenuation Class (CAC) relates to sound transmission through a shared ceiling plenum between adjacent spaces. These ratings describe different properties. The design team should identify the relevant requirements for the complete room design. See Armstrong’s explanation of NRC and CAC for background.
Coordinate materials and visible details
Suspended acoustical systems come in different sizes, textures, and core materials. Confirm the specified product, edge detail, grid arrangement, finish, and any moisture-related requirements. Resolve how the ceiling meets walls, soffits, and specialty features before those details become field questions.
Bring the ceiling plan and other trades together
Lighting, diffusers, sprinklers, access needs, and other ceiling elements share the same space. Provide the reflected ceiling plan and relevant details with the bid documents. Identify revisions and open coordination items so the installation scope can be reviewed against the current design.
