panels must be attached
to solid framing such as 2x4 supports
spaced no more than 24 in. o.c.
For eaves install HardieSoffit panels
with the long edge of the panel
perpendicular to the ends of the
rafters or joists. Eaves framing must
include a subfascia, blocking, and/or
ledger board to provide solid nailing
along the long dimension of the soffit.
All panel edges must be supported.
For rake overhangs 2x “look outs”
spaced a maximum of 24 in. o.c.
should support a rake subfascia to
provide adequate nailing for the rake
soffit. Blocking between the lookouts
provides support for the rake soffit
along the building.
There are several ways to join the
lengths of HardieSoffit panels.
Panel ends may be lightly butted in
moderate contact, the ends may
be gapped
1
/8 in. and caulked,
joints can be covered with batten
strips, or panels may be joined
with PVC or metal H molding
type connectors.
JOINT TREATMENT FOR HARDIESOFFIT PANELS
Soffit Framing
TIP: To aid in soffit panel installation, make a “deadman” or “third hand” post
to help hold and position the soffit panel. Factory built tools such as those
made for drywall installation are available, or they can be fabricated from
lumber on the job-site.
