Division 09 — Finishes: how to specify products in it
Gypsum board, tile, ceilings, flooring, wall coverings and paint. Division 09 is where most of a building’s surface area gets decided, and where finish-schedule errors begin.
What Division 09 covers
Interior finishes from the stud out: gypsum board assemblies and non-structural framing, plaster, tile and stone, acoustical and specialty ceilings, resilient, wood, tile and carpet flooring, wall coverings, acoustic treatment and paints and coatings.

What to check before you specify
- 01Flame spread and smoke development — the finish’s classification against what the code allows for that room and occupancy.
- 02Slip resistance — wet and dry values for flooring, measured to the standard the project references.
- 03Acoustic performance — NRC and CAC for ceilings, IIC and STC contributions for floor assemblies, from tested data.
- 04Durability and wear — abrasion, impact and moisture ratings matched to the room’s use.
- 05Substrate and installation requirements — moisture limits, flatness and primers that the warranty depends on.
- 06Sustainability data — low-emitting certifications and environmental product declarations where the project requires them.
