Siding Replacement Question

[Megan Phillips]

I know someone on here will know this: I'm trying to find siding online  to replace some old and rotting siding,  but I'm not sure exactly what it is. I'm assuming it's fiber cement, but I've never had fiber cement siding before, so who knows. It's brown and reminds me of finer pieces of OSB board.

It's smooth (no fake grain lines) and measures around 8.75inches, maybe a touch wider. 

When I look online, the widest I see is 8.25 inches (hardie). I checked Home Depot, they had only an even smaller width in store. 

If I can figure out how to add a picture from my phone I will, or I'll definitely add tomorrow. 

Is there wider fiber cement siding available online somewhere? 

Also, someone at BP should start a DIY forum.
