Hardie Panels
Hardie Panels
(OP)
Anyone know what the maximum recommended deflection ratio is for the panels?
I can't find anything in the ESR's, and their technical help line is really lacking.
Thanks.

RE: Hardie Panels
I’m really not sure what you want or mean, and I don’t have the ICC-ESR in front of me. Don’t they show any mechanical properties and section properties in their report, which you could use to do some deflection calcs? Could you compare this to other sheet or lap siding values and recommendations, as a guide line. Don’t they have some support spacing recommendations for their various products? I would try actually talking with someone in their engineering dept., I just haven’t had much luck with the half-assed responses we get from an e-mail exchange. These days, everyone wants a new product to bring to the market, but then they do a damn poor job of testing and proving or disseminating pertinent design info., or of customer service and designer service before problems with the product start showing up. We are their guinea pigs or testing service these days, and ten year later we can sue them for satisfaction of a problem if we can find them or afford the suit. I do know that the products will wick-up water, so you want to keep them (their butt/cut ends or edges) well above any water level (roof plane, grade) which might cause this.
