of this class are not readily flsm_s_ble and do not readily carry
or communicate fire, afford a m~derate degree of heat insulation
to the roof deck, do not slip from position, possess no flying
brand hazard, but may require infrSquent repairs in order to

this class are not readily flamable and do not carry or commun-
icate fire; afford at least a slight degree of heat insulation
to the roof d. eck$ do not slip from position; possess no flying

a minimum ~ix inch (6") embedment in the masonry or concrete and
spaced not more than four feet ap~rt. There shall be one such bolt
in addition at each corner or offset in the wall. In exterior
frame wall construction, where foundation walls are not poured
monolithic with the footings~ bolts must extend through the walls
and into the footings, regardless of whether the walls are solid.
0ne-half inch steel dowels extending from the footing and adequate-
ly lapping the bolts are construed as co~plying with the require-
ments of this section. If hollow walls are used, the cells in
which said dowels are located must be solidly filled with concrete
or grout. All foundation sills shall be treated for rot and
termite prevention, and shall be separated from contact with found-
ation walls of masonry by not less than 28 ga. galvanized iron or

that the building is effectively tied down from the rafters through
the building to the footings. All strap nailing shall be in shear.
Roofs with unusually large overhangs (more than two feet horizontal
projection) may require additional tie down subject to the discre-
tion of the Building Official. Show rafters in eave overhangs
must be extended inside of the supporting member approximately the
