can be disassembled, relocated, and substantially
reused. System shall consist of vertical gypsum
board panels, floor runner, top rail, splice
studs, trim, and
accessories. Partition shall be [3-3/8] [4-1/2]
inches thick and provide 1-7/8 inches wide
cavity for distribution of utilities.
******************************************************************************
If including performance specifications, edit Section
carefully to avoid conflict between descriptive and
performance requirements. Refer to USG product literature
and test reports for design requirements and
limitations of each performance rating. Coordinate
partition performance with specifications for
doors, glazing, penetrations through partitions,
and perimeter construction.
******************************************************************************
1.05 PERFORMANCE
******************************************************************************
UL U427 (One-Hour) requires "H" or "T"

height.
2. System shall withstand five 30 ft. lb. impacts
with no observable damage. Instantaneous
deflection shall be one inch max., permanent deflection
set shall be 0.10 inch max.
