weather barrier including complete installation requirements.
IBC Code Reference: “1403.2 Weather protection. Exterior walls shall provide the building with a weather-
resistant exterior wall envelope. The exterior wall envelope shall include flashing, as described in Section
1405.3. The exterior wall envelope shall be designed and constructed in such a manner as to prevent the
accumulation of water within the wall assembly by providing a water-resistive barrier behind the exterior
veneer, as described in Section 1404.2, and a means for draining water that enters the assembly to the
exterior. Protection against condensation in the exterior wall assembly shall be provided in accordance with the
International Energy Conservation Code.
Exceptions:
1. A weather-resistant exterior wall envelope shall not be required over concrete or masonry walls designed in
accordance with Chapters 19 and 21, respectively.
2. Compliance with the requirements for a means of drainage, and the requirements of Sections 1404.2 and
1405.3, shall not be required for an exterior wall envelope that has been demonstrated through testing to resist
wind-driven rain, including joints, penetrations and intersections with dissimilar materials, in accordance with
ASTM E 331 under the following conditions…”
WATER-RESISTIVE BARRIER
Heavy building products and components such as roofing, drywall and floor coverings should be stored throughout the
structure prior to the installation of the siding. Distributing the weight in this manner will reduce the possibility of floor
plate compression on two or more story homes.
STAGING
FLASHING
When using James Hardie siding, trim, and weather barrier products, make sure that roof flashing, water table
flashing, window and door flashing, and flashing for other building envelope penetrations are properly installed and
lapped so that moisture drains down and to the exterior. Note: The successful installation of flashing requires thorough
planning before installation of roofing or siding. Scheduling and sequencing are important factors as well as having the
correct flashings available on site at the correct time. James Hardie does not recommend the use of mill finished, raw
aluminum flashing or any other product that may bleed or adversely react with cement products. Painted or coated
aluminum flashings are recommended.
Manufacturers of ACQ and CA preservative-treated wood recommend spacer materials or other physical barriers to
prevent direct contact of ACQ or CA preservative-treated wood and aluminum products. Fasteners used to attach
HardieTrim Tabs to preservative-treated wood shall be of hot dipped zinc-coated galvanized steel or stainless steel and
in accordance to 2009 IRC R317.3 or 2009 IBC 2304.9.5.
IBC Code Reference: “1405.3 Flashing. Flashing shall be installed in such a manner so as to prevent moisture
from entering the wall or to redirect it to the exterior. Flashing shall be installed at the perimeters of exterior door
and window assemblies, penetrations and terminations of exterior wall assemblies, exterior wall intersections
with roofs, chimneys, porches, decks, balconies and similar projections and at built-in gutters and similar
locations where moisture could enter the wall. Flashing with projecting flanges shall be installed on both sides
and the ends of copings, under sills and continuously above projecting trim.”
