Using ever build - black jack all weather roof coating.. For wall sheating, osb or plywood is acceptable, but again, plywood is preferable unless extreme cost savings is a concern. cost savings for osb vs. plywood. the cost savings of osb over plywood will be less than 2% of the total cost of most homes. if we were building a new home, we’d choose plywood given only these two choices..
Osb is then used in the interior or field panels of a roof where wind is not as much of an issue. plywood grasps the nails holding flashing, the finished roofing like asphalt shingles, or the like, better, especially long-term, than osb which tends to soften more quickly with moisture cycles over the years.. Osb and plywood are both commonly sold in 4-by-8-foot sheets, but osb can be made in much larger panels, up to 8-by-24 feet. using larger osb panels can be an advantage when flooring a big or odd-size shed, reducing the number of joints in a floor.. Osb isnt suitable for direct exposure to the elements, its good stuff for shed floors and roofs though. cheapest way to board it out would probably be shiplap surely. goldenboy , mar 3, 2010.
