Vertical vs. Horizontal Sheathing – The TRUTH According to Code

Do you have to hang wall sheathing horizontally? What about vertical orientation — is it wrong, weaker, or just misunderstood? In this video, Tim dives into one of the most common framing myths: that wall sheathing must be installed horizontally. Using published data from APA – The Engineered Wood Association, LP, Huber Zip System, West Fraser, and more, we walk through real code excerpts, testing standards, and engineering references that clarify what’s actually allowed — and when.

Commercial work includes social media like YouTube if you plan to make an income off of that. I watched a video about this last May and then purchased the Part 107 Course https://sso.teachable.com/secure/2458... I studied and learned for 1 month and then took my test. I scored a 95%, which is a testament to how good Greg and the crew over there teach.
