ceilings, floors or shafts from the structure by piping isolator or by 3/8-inch thick
foamed rubber insulation. Install units flush with finished structure face, using
one for each side as required. Cut units to length if longer than structure
thickness. Caulk around pipe or duct at equipment room wall.
7. Hot and Cold Plumbing Pipes: Isolate hot and cold water piping in plumbing
chases and walls behind plumbing fixtures,which are adjacent to occupied
areas,from the structure by a piping isolator, Cush-A-Strip S-716, or a 6-inch
section of 3/8-inch thick foamed plastic between the hanger and pipe.

assembly but not in contact with the building structure. Install hangers so that
the hanger housing may rotate a full 360 degrees about the rod axis without
contacting any object.
5. Where parallel running pipes are hung together on a trapeze which is isolated
from the building, provide isolator deflections for the largest determined by
provisions for pipe isolation. Do not mix isolated and nonisolated pipes in the
same trapeze.
