HardieSoffit Boards – Installation Requirements
Did You Know?
HardieSoffit Boards – Standard Soffit
 HardieSoffit panels must be attached to solid
framing (typically 2x4 supports spaced no more
than 24” oc)
 HardieSoffit runs lengthwise in the eaves, with the
panel width (12”, 16” or 24”) running from the
building out.
 Eave framing must include a Subfascia, rafter/truss
blocking, and/or a ledger board on the wall to
provide solid nailing along the long dimension of
the soffit.
 ALL Panel Edges MUST be Supported.

HardieSoffit Boards – Gable Rake Soffit
 For rake overhangs on gable ends 2x “lookouts”
spaced a maximum of 24” oc should be installed to
support a rake Subfascia to provide adequate nailing
for the rake HardieSoffit.
 Install blocking between the lookouts or run a
continuous ledger on the wall to provide support for
the HardieSoffit at the building.

2. HardieSoffit Panel Joints may be covered with batten strips.
3. HardieSoffit Panel Joints may be joined with a PVC or Metal H molding or Trim.
4. HardieSoffit Panel Joints may be gapped 1/8” and caulked (Primed Product ONLY)

Installation of HardieSoffit Panels
Preparation for HardieSoffit Panels: Required Framing
Fig 1.1
When Installing the Soffit:
1)
Straighten the rafter tails by pulling and snapping a
chalk line across the ends of the tails and then
trimming them as necessary. (Figure 1.1)
2)
Install a solid wood sub-fascia on the ends of the
rafter tails or install blocking between the rafter tails
as needed. (Figure 1.2)
Fig 1.2
3)
In order to close in the soffit area, add nailers at
every rafter or truss to provide support.

Preparation for HardieSoffit Panels: Positioning & Fastening
When Installing the HardieSoffit Panels:
1)
If the eaves are longer than 12’, measure and trim the
first HardieSoffit panel making sure that the end falls
in the middle of a nailer.
2)
Using the sub-fascia as a guide along the edge,
carefully position the panel and secure with 4d
common galvanized nails spaced no greater than
8”oc at all panel edges and on all intermediate
framing members.
3)
Continue with additional pieces until the run is
complete. Remembering to keep the vent strip to the
outside of the eave.

Preparation for HardieSoffit Panels: 45 Hip Roof Framing
Hip roof soffits continue level around the corners of the
house. The soffit panels should join at the corner with
two 45o angle cuts.
To Create these Corners:
1)
First measure from the corner to the perpendicular
framing member closest to, but not over 12’ feet.
2)
Using that measurement and pulling from the factory
cut end of the soffit panel, mark the outside edge of
the soffit panel for the long point of the 45o cut.
3)
After cutting the 45o angle, position the panel on
the soffit framing and check the fit on both ends
before fastening.
4)
Begin nailing at the 45o cut end and work toward
the factory end.

Soffit to Wall Treatment Options for HardieSoffit Panels:
In addition to the frieze board treatments described above, there are several
other options for finishing the juncture where the siding meets the soffit.
CAULK THE SIDING/SOFFIT JOINT:
 A fast and economical method of finishing the siding/soffit juncture is
simply to run a bead of quality permanently flexible caulk along the top edge of
the siding where it meets the soffit. Make sure the last piece of siding installed
is ripped straight so it looks aesthetically pleasing.
OVER THE TOP OF THE SIDING WITH “J” CHANNEL:
 Once the Soffit is in place, install a vinyl “J” channel upside
down with the base of the “J” against the soffit. Then rip the final
course of siding so that it fits inside the channel.
INSTALL AN EXTERIOR CROWN MOLDING OR CORNICE TRIM:
 Crown molding or trim is another way of finishing and sealing the
soffit/siding juncture, install and finish the crown molding or trim according to
the manufacturer’s specifications.

HardieSoffit.
1)
Ensure the insect screen laps by 1 – 2 inches over the nonvented portion of the HardieSoffit Panel.
2)

portion of the HardieSoffit using a bead of construction
adhesive.

2)
Fastener Spacing is 8” oc into solid framing members spaced no
further apart then 24” oc maximum.
