Firestop Radiation Shield
A Firestop Radiation Shield is required in multistory installations
at each floor penetration above that where the Support Box is
located.
Firestop Radiation Shields also provide complete separation
from one floor space to another or attic space as required
by most codes. When the double wall pipe passes through
a framed opening into an attic space, the firestop must be
placed into an attic floor as shown in
Figure 28
.
Follow your chimney manufacturer’s instructions on specific
guidelines pertaining to their chimney and Firestop Radiation
Shield installation instructions.
