Siding Identification

I have a realtor that has this siding on the house and he asked me to identify it. I have seen it before but I don’t know anything about it. Does anyone have any information on this?

Looks like a cement fiber board siding. Depending on its age it may contain asbestos. Google “transite siding” and look at the images.

It’s not that, it has a cellulose “core”.

It’s in the same family as Insul-Brick.
