I’m calling this video the third installment of my shop improvements series. It’s not a highlight of a single project, though. Since none of these things would make an interesting video on their own, I’m using this video as a catchall. I talk about and show the insulation and sheeting of the walls and ceiling, including painting OSB sheeting. Dealing with the barn doors, a random gap in the doorway of the shop that I filled with concrete, and reinforcing the sagging ceiling with additional joists.
