Yes is the quick answer. How wet is the more important question. If you encounter rain on the way from the lumber yard to the job site, this is not a big concern. If the the material sits for days out in the rain uncovered the material will warp and start to delaminate.
Roof decking, exterior sheathing.
OSB's share of the North American sheathing market, which stood at 50 percent in 1998, increased another 25 percent between 1998 and 2003.
Rolled tar paper is used in that situation as a moisture barrier.
Yes, or it will take a lot of paint due to the fact that the osb will soak it up.
OSB stands for oriented strand board. It is made of wood strands and waterproof adhesives. The strength of OSB board is equal to that of plywood.
If someone wanted to purchase an OSB there are a variety of places where someone can do so. Some of these places are Calibex, Fordaq and cheap osb and nsbe.
This depends on what you're asking: if you want to know whether you can build the structure exclusively out of OSB sheet goods, the answer is no, not if you want it to last more than a year or two. OSB is very stable in the plane parallel to the surface, but the edges do not take fasteners well. Years ago I used a lot of OSB 2 x 4 for framing stage decking, but I'm not sure that product is manufactured anymore. OSB sheathing is used for walls and roofing over traditional 2x lumber, and I think you'd still want to clad the exterior walls with wood or vinyl siding, for durability if not for aesthetics. And you'd certainly want to use a standard roofing material (shingles, corrugated metal, corrugated plastic, roll roofing--all dependent on the roof pitch).
OSB
That depends if it's an interior or exterior wall. Interior walls are basically studs (2x4 pine lumber) covered with drywall ("sheetrock" is a common brand). Exterior walls can use 2x4s or bigger lumber (2x6s), with insulation in between them. The inside part of the wall is covered with drywall, the exterior is usually covered with plywood or OSB sheathing. In some cases, there is simply foam board on the outside. Then that (the plywood/OSB or foam) is covered with some sort of siding material (vinyl, wood, brick, etc).
