may be preferable to avoid aluminum flashings

. . based on the actual weight of the coating; for
example, a G-60 rating means 0,60 ounces of zinc
per square foot of metal, G-60 and G-90 hot-dipped
coatings have been used until now, but engineers
suggest G-185 coatings for hot-dipped galvariized
.products and class. ratings of40 or above when
using electro-galvanized fasteners, such as
expansion bolts. Currently, G-185 is the best gal-

A Taking CCA's pl~ce'are !WO w'~t~rbome-
compounds, alkaline copper qual (ACQ'types B
and D) and copper azole (CBA:A, 'CA-B): Sold.
under the tnide names Preserve, NatureWood, and .'
Natural Selel:t, they."have been 'used around the .
world for about 15 :years, These EP A-approved
Iow~toxicity products resist bugs, mold, and rot as
effectively as CCA. . .
Q Are the new preserva'tives safe?
A The new preservatives have been studied
extensively and approved for uSe by the EP A, Like
CCA, theyproceCl and extend the life of wood
products for deCailes, .
Q Will the new wood p~oducts cost more?
A To make the new preservatives effective: the~ .
copper content has been boosted substantially -
from around 18 percent to 96 percent Bel:ause
. ACQ and copper azole cOntain so much more
copper, ~xpel:t to pay more, somewhere between 10 .
. and 35 percent more. Cost will vary depending on
chemical treaanent. CCA wasn't that expensive, so
most CCA lumber was given a maximum dose of
. preservatives and rated for ground contact.
To keep down the cost of the new presSure-treated
. wood, manufacturers will prodUce different levels
~f ~w~~on (chemica1-retentionlevels) fordiffenmt
uses. End-use categories will be on the tags stapled'.. .
to the end of the board, but generally will be
determined by the dimension of the lumber itself,
Q Are these productS avai!;lbl~ today? . .
A There are limited supplies of w.cod products
treated with the new preservatives on the market,
that will change as the industry retools. For more'.

Cripple wall bracing, Cripple walls with a stud height exceeding 14-inches
supporting exterior or interior braced wall lines shall be braced with an
amount and type of bracing as required for the wall above with the following
modifications for the cripple wall bracing:
a) The required amount of bracing as determined for the wall
above shall be increased by 15 percent,
b) The maximum wall panel spacing shall be decreased to 18 feet
on center instead of 25 feet on center, as normally required.
Note: Cripple walls supporting three stories have additional requirements,
Stepped foundations, Where stepped foundations occur the following
requirements apply:
a) Where the height of a required braced wall panel that extends
from the foundation to the floor above varies more than 4-feet,
the braced wall panel shall be constructed in accordance with
Figure R602,ll,3
b) Where cripple walls occur between the top of the foundation
and the lowest floor framing, the bracing requirements for an
additional story shall apply.
