First of all, is my terminology correct? These are brands of synthetic wood alternatives:

Is “construction board” the generic name for this stuff? I think some people call them “building panels”. I ask because my search for Invidious (Youtube) vids came up short. I would rather not have a brand-dependent search query because I have to try many queries as it is to try to get this answer.

Qboard offers a factory made corner piece (called Qorner; attached to this post). I was trying to work out how I could do that myself. I’ve never worked with #constructionBoard, nor have I used a router, but I suspect they use a router to cut a “V” in the board without competely bottoming out (but nearly), so the outer skin does not get cut. Has anyone done this?

    You wouldn’t use fasteners in the joint itself, and you’re exactly right that they would pull right out. The screws are used to fasten through the face of the wedi board to wooden studs behind it to provide strength, and then the penetrations and joints are all sealed with the wedi sealant. The board itself is waterproof, you’re only sealing the joints/penetrations. I believe that small shower niches with 1/2” board are sturdy enough that they don’t even need wooden framing and just rely on the board+sealant, but am not sure on that.

    I’m not sure if this is the latest version, but this technical document has a ton of information: https://www.masterwholesale.com/media/wedi_Technical_Handbook_January_2021_Digital.pdf
