Hi @Medic ,
thanks for the feedback! It is OSB3.
Sorry my bad, you are right. There is no reference to which OSB or its properties in the beams paper.
All the data about the material properties are in another paper, you can find it at this link: WikiHouse
It is the same that appears in part of the video.
Let me amend the beams paper to redirect the reader to the material one, and also add the link into the comments.
Furthermore, yes, I have also come across OSB 4 (although quite recently). That seems super promising. We will definitively have a better look into it. Thanks for recommending it!
