HardieSoffit Installation of HardieSoffit Panels Preparation for HardieSoffit Panels: Required Framing Fig 1.1 When Installing the Soffit: 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) 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 “Nailer” In order to close in the soffit area, add nailers at every rafter or truss to provide support.
HardieSoffit Installation of HardieSoffit Panels Preparation for HardieSoffit Panels: Positioning & Fastening When Installing the HardieSoffit Panels: 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. 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. Continue with additional pieces until the run is complete. Remembering to keep the vent strip to the outside of the eave.
HardieSoffit Installation of HardieSoffit Panels Preparation for HardieSoffit Panels: 45o 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: First measure from the corner to the perpendicular framing member closest to, but not over 12’ feet. 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. Aftercutting the 45o angle, position the panel on the soffit framing and check the fit on both ends before fastening. Begin nailing at the 45o cut end and work toward the factory end. 1 2

HardieSoffit Installation of HardieSoffit Panels 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 Installation of HardieSoffit Panels HardieSoffit Panels: Installation of additional Insect Screen (where required) When Installing Additional Insect Screen in the Soffit: Cut insect screen so it covers the vented portion of the HardieSoffit. Ensure the insect screen laps by 1 – 2 inches over the non-vented portion of the HardieSoffit Panel. Secure the insect screen to the backside of the vented portion of the HardieSoffit using a bead of construction adhesive. 1-2 inches
HardieSoffit Installation of HardieSoffit Panels HardieSoffit Panels: Required Fasteners & Fastener Spacing When Fastening HardieSoffit: Ensure all Panel Edges break on solid wood framing. Fastener Spacing is 8” oc into solid framing members spaced no further apart then 24” oc maximum. Keep Fasteners 2” from corners and 3/8” in from HardieSoffit Panel Edges. Stainless Steel Fasteners are always recommended when installing all James Hardie Products. 8” Inches
