102 TIP: For Sierra 8 panels, double studs at each panel joint allows fasteners to be placed outside of panel grooves. TIP: It is common practice to mark panels for cutting with a chalk line. Blue chalk is recommended because it washes off. Red chalk is considered permanent and may bleed through lighter colored paints. TIP: To give the installer more control while setting the first course of wall panels, rest the panels on a couple of large common nails inserted between the plate and the foundation. Water resistive barrier 16-d nails for temporary support Snapped chalk line guides the...

103 vertical jo int treatment Treat vertical joints in HardiePanel® vertical siding by using one of the following four methods: 1) Install the panels in moderate contact. 2) Leave an appropriate gap between panels (1/8 in. is the most common), and caulk using a high-quality paintable caulk, that meets ASTM C-834 or C-920 requirements. Panels may be installed first with caulk applied in the joints after installation; or as an option, after the first panel is installed, apply a bead of caulk along the panel edge. When the next panel is installed against the first, the edge embeds in the...

105 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. Below is one method for properly flashing trim in a panel application: 1) After installing the window, cut and install a 1/4-in. 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. 2) Over the shim install flashing that is wide enough to allow for the thickness of the trim. 3) Install the panel to the window and around the shim taking care not to damage the...
