A sound-control batt is missing around a plumbing penetration in a rated corridor wall. What is the best field response?

Correct Answer

B) Fit the insulation around the penetration and maintain the required wall assembly details.

Acoustical insulation should be fitted so the intended assembly is continuous around penetrations while required fire and wall details are maintained.

Answer Options
A
Leave the gap because pipes provide enough sound blocking.
B
Fit the insulation around the penetration and maintain the required wall assembly details.
C
Remove all insulation from that stud bay so the wall is uniform, from floor to ceiling around every penetration.
D
Pack loose debris into the gap before the wall is closed.

Why This Is the Correct Answer

Acoustical insulation should be fitted so the intended assembly is continuous around penetrations while required fire and wall details are maintained.
