4X8 sheet hardiboard installation

[Richie Rich]

Using 1/4" 4'x8'sheets of Hardieboard which appears to have no lap edge, how are the seams sealed?

I've seen the responses to Brian(04/2005) and take note of the potential issues of nailing too close to the edge and breaking corners. Also liked the idea of shimming if the framer can't make straight lines.

Any other information about using hardieboard will be appreciated.

Horizontal joints must have Z-flashing.

Vertical joints, if installed over a weather resistive barrier, are not required to be sealed but are installed "in contact". It is preferred to install PVC "H" channel, battens or leave a gap and caulk.
