Rob, that is what we are redoing our house with. Our SIP's had extruded channels for 1/4 paneling - 30 years in Puna made for some very interesting waves in the paneling, so we decided to go with the smooth Hardipanel (it was the only product we found that would fit the channels & take humidity). There is one GIANT caveat...Hardipanel is a bear to cut for recepticle holes & such...grinds through carbide bits & saws...have to cut every thing very slowly to minimize heating the blades. For weight reduction in the raised ceiling areas, we are looking at other stuff...hence our interest in the GP product...still gotta do the research on it.
