French to English Tech/Engineering Construction / Civil Engineering Barn construction

Hi everyone,

I would really appreciate it if anyone could confirm whether I could use "stock walling" in English for this. There is a drawing which is pretty unhelpful but it just seems to be vertical boards laid next to each other. There is no overlap, the sides seem to sit flush next to each other. This is presented as the most basic option in timber siding. I did find a site with a good image of what this is:http://www.ecurieprivee.com/fr/index.php?page=62.
Thanks for any help you can provide.
