100 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 applied...

The horizontal joints created between panels must be flashed properly to minimize water penetration. Treat horizontal panel joints by using one of the following methods: 1) After installing the lower course of panel siding, install vinyl or coated aluminum “Z” flashing at the top edge of the panel. Make sure that the flashing is sloped away from the wall and does not rest flat on the top edge of the panel. Install the second level or gable panels...

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 flashing...
