Trim
BUTTING TO MORTAR OR MASONRY
James Hardie
®
siding and trim products should not be butted
directly against mortar or masonry, including stone, brick, or
concrete block. In these situations, a flashing should be installed
to isolate the trim or siding from the mortar or masonry.
AIR CONDITIONERS, SERVICE PANELS, AND OTHER WALL MOUNTED DEVICES
Wall mounted devices and air conditioners represent large penetrations into the building envelope and structure.
Before installing a unit, please consult the architect or structural engineer to determine if additional bracing is
necessary. The device should be installed per manufactures instructions and flashed properly. Any condensate drains
should extend out 4 in. from the wall, and angle down.
WIRES, CONDUIT OR OTHER FIXED PIPES
For small penetrations such as wires, electrical conduit, and
pipes less than 1-½ in. in diameter (excluding hose bibs) no
blocking is necessary. The circumference of pipe or wire
should be sealed with a barrier foam and/or caulked.
