Yes, my home has OSB sheathing. I know this because I cut and put it on there with my own two hands. I put it right over the original 1" thick shiplap planks, laid at opposing 45° angles, that the house was originally built with in the 1890s. Of course I had to do this because the original shiplap has expansion gaps between each piece which kept the home remarkably straight over the years, but really sucked as an insulation barrier. Now I've installed proper sheathing and weather barrier to the structure of the home, as well as insulation in the wall cavities, my home is much more energy efficient.
It's fucking sheathing people, not the main bearing of structural load of the home, and every fucktard that makes these threads have no clue as to what they are talking about.
