 9.10.16.2. Required Fire Blocks in #Wall Assemblies

#Furring or #strapping can also create spaces that allow fire spread. These should also be blocked off at each #floor level and at the #ceiling level if the ceiling #membrane provides part of the required fire resistance (Figure 9.10.-38). Since furring can be installed either horizontally or vertically, both the horizontal and vertical spacings of fire blocks are limited (20 m (65 ft. 7 in.) and 3 m (10 ft.), respectively).
