hello and welcome to installing with the

manufacturer a series of instructional

video segments that will outline the

basics of installing James Hardie

products this site is dedicated to

educating and instructing you on the

most innovative and up-to-date best

practices for installing James Hardie

products James Hardie is the world

leader in the manufacturing and

development of fiber cement building

products we have produced an

installation guide to help you with the

installation of our products please be

sure to download a copy prior to

watching these instructional videos

there is a link provided on this site in

this segment we'll cover the basics of

installing hardy panel vertical siding

to begin you must first locate the

lowest point of the sheathing or seal

plate and begin installation on that

wall measure up from the seal plate the

height of the panels at either end of

the wall and snap a straight level chalk

line between the marks as a reference

line that line is for guidance and

positioning the top edge of the panel's

check the reference line with a

four-foot level starting on one end and

working across the wall measure and trim

the first panel making sure that the

edge falls in the middle of a stud using

the chalk line as a guide along the

panels top edge carefully position the

panel and secure it with suitable

fasteners and fastener spacing for the

particular application as noted in the

NER 405 which can be found on WWJ MCRD

comm as installation continues check the

vertical edge of each panel with a

four-foot level when treating vertical

joints in hardy panel vertical siding

use one of the following four methods

install the panels and moderate contact

or to leave an appropriate gap between

panels 1/8 of an inch is the most common

and caulk using a high-quality paintable

caulk that meets ASTM C 834 or c920

requirements a third option for treating

vertical joints is to use batten strips

if James Hardie siding or trim products

are ripped and used as batten strips

painter prime the cut edges batten

strips should span the vertical joint by

at least 3/4 of an inch on each side the

fourth option is to use metal or PVC h

moldings to join two sections of hardy

panel siding

now we're going to talk about horizontal

joint treatment in some applications

such as multi-story structures or a

gable ends it may be necessary to stack

hardy panel siding the horizontal joints

created between panels must be flashed

properly to minimize water penetration

treat horizontal panel joints by using

one of the following methods after

installing the lower course of panel

siding install a vinyl or coated

aluminum Zee flashing at the top edge of

the panel make sure that the flashing is

sloped away from the wall and does not

rest flat on the top edge of the panel

install the second level or gable panels

leaving a 1/4 inch minimum gap between

the bottom of the panel and the Zee

flashing this gap should never be caught

as an alternative if a horizontal band

board is used at the horizontal joint

flashing must extend over the panel edge

and trim attachment flashing for both

treatments must slip behind the water

resistant barrier remember do not bridge

floors with panel siding the horizontal

joint should always be created between

floors this will require proper planning

with wall and panel layout before you

begin installation a few tips for

better-looking walls would be to plan

the installation so that full panels are

centered on the wall or gable with equal

size panels cut for each end as an

alternative you may also install panels

so that a full panel is located on

either side of the wall Center again

leaving equal sized panels on each end

these strategies might entail a sintered

framing layout choose the strategy that

looks the best and uses material most

efficiently now let's discuss windows

and doors and other wall penetrations in

panel installations trim is typically

overlaid on top of the panel special

attention needs to be paid to trim

flashing at the tops of openings after

installing the window cut and install a

1/4 inch thick shim above the window the

shim should be the same width as the

trim and it should be as long as the top

or header piece of trim over the shim

install flashing that is wide enough to

allow for the thickness of the trim to

be installed install the panel to the

window and around the shim taking care

not to damage the flashing

leaving a 1/4 inch gap between the panel

and the horizontal part of the flashing

install the trim around the window

slipping the headpiece under the

installed flashing this concludes this
