Interior Systems – Details

The details that follow are standard details that depict proper detailing for interior non-load bearing partitions.  The source of these details is either ASTM or the Gypsum Association.  The intent is to serve as a guide.  Final approval of detailing for a specific construction project is the right and responsibility of the Architect of Record.

ACOUSTICAL HEAD – OF- WALL

1. Continuous bead of acoustical sealant in contact with gypsum panels, track, and structure.
2. To allow for differential movement, no mechanical fasteners between gypsum panels, track, and stud.
3. Check with Underwriters Laboratories for specific fire rated head-of-wall designs.
4. Source:  Gypsum Association, GA-600 Fire Resistance Design Manual.
5. Attach track to structure with appropriately sized and spaced fasteners.
6. Nominal 3/8” gap between top of gypsum panels to bottom of structure.
