Re: Brick walls on top of gable roofs

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Is it the intent of the national codes (UBC '97 2307, BOCA '96 2112.3  and
SBC) not to have any masonry directly supported by wood? I also assume
that they are refering to vertical support only and not lateral support.
What about the case where the masonry is supported by a steel angle which
in turn is supported by a wood stud wall? I assume the concern is for the
wood supports rotting out if the masonry is in direct contact. What if you
are supporting only a few feet of masonry?
