45
Q

In most buildings firewalls must be constructed of

Q

The international building code also permits combustible structural members to be framed into a masonry or concrete firewall from opposite sides provided there is a____ separation between the ends of the structural members

A

4 inch

47
Q

Firewalls must extend beyond the walls and roof to prevent the radiant heat of flames on one side of a firewall from igniting adjacent surfaces. This is accomplished by continuing the firewall through the roof with a
