Step 17.6 - Sheathing and Shear Panels

The stud work for the garage is completed and we can begin enclosing it. For the walls, this consists of shear panels made of oriented strand board (OSB) which is an engineered wood product that is as strong as plywood but somewhat less expensive. The purpose of shear panels is to give the wall additional strength and rigidity. OSB isn't the best looking material, but it will be totally covered up by drywall on the inside and siding on the outside.


For the roof, the sheathing is tongue-and-groove plywood. This same material is used for the floor of the loft. The plywood as well as the rafters will be visible from inside the garage so our plan is to paint it at a later time. Mark and his crew had to construct a temporary platform above the roof to hold the plywood until they are ready to lay it down.
