Combustible Wall Penetration

Frame a hole in a combustible wall for an interior wall shield firestop, (Figure 6.2) whenever a wall is penetrated. Use same size framing materials as those used in the wall con- struction. The wall shield firestop maintains minimum clear- ances and prevents cold air infiltration.

Non-Combustible Wall Penetration

If the hole being penetrated is surrounded by noncombusti- ble materials such as concrete, a hole with diameter one inch greater than the pipe is acceptable.
