It's a cement board panel called Cembonit. Honestly, I don't think it's available in the states anymore. It is made in Europe, and I guess the company stopped exporting it. There is a rubber gasket system for the seams, but it sets behind the panels. It's an integral color panel, with no paint, so the color is what it is. It comes in 10 or so different colors. Look up cbf11.com. That is the state-side distributor. They have a new product called Sil-Leed panels that are very similar. Another company to check out would be Cladding Corp. Both offer similar products, but we haven't used them yet.

Thanks for the specific information. I have been following several conversations on Cement Board siding. This one is particularly interesting because of the seam/reveal treatment. Is the gasket system you mention available here in the states? I love that it remains completely behind the panels. I have not been satisfied with the reveal options that I have seen, but this sounds fantastic. Thanks again.

Has anyone explored the Nichina panel system? Their "Illumination Series" and "Block Panels" operate on a hidden clip system. While the company is Japanese, the HQ is in Georgia. Its about 4.2lbs/sf. I'm a homeowner doing research and wonder if this is too heavy for 2x4 construction. http://www.nichiha.com/
