James Hardie siding
Flashing
James Hardie does support the use of its exterior
siding products installed over rigid foam insulation,
but does not take responsibility for the entire wall
assembly or system. James Hardie expects the
designer or builder using our components as part of
the insulated wall assembly to:
• Adhere to all the installation requirements listed in
the relevant product installation instructions.
• Provide adequate details for water management.
• Make the decision about the use and type of rigid
foam insulation.
• Understand the interaction between system
INSTALLING OVER RIGID FOAM INSULATION UP TO 1 THICK
General requirements and installation guidelines:
• All James Hardie
®
product specific installation requirements must be followed.
• All national, state, and local building code requirements must be followed. Where they are more stringent than the
James Hardie installation requirements, state and local requirements will take precedence.
• James Hardie siding and trim products can be installed over solid-foam insulation board up to 1 inch thick. Caution
should be taken as irregularities and unevenness in framing, sheathing, foam and other wall assembly components,
including under driven nails, can telegraph through to the finished siding and trim. These irregularities should be
corrected before the siding is installed.
• When reviewing the following details for attaching over foam,
an important consideration is that the fastener chosen must be
adequately encompassed by a wood substrate. The foam will not
count as part of the necessary penetration, there for the length of the
chosen fastener must be extended by the thickness of the foam.
Fastener Selection:
• When attaching lap siding products over foam 1 or less, the length of
the chosen fastener from table below, must be extended in length by
the thickness of the foam. For information on fastening Hardie products
greater than 1 in. see Tech Bulletin 19 at www.JamesHardie.com.
