Can you use plywood as outside wall?

Plywood is a frequently used material for external structural sheathing. It’s made up of several thin layers of wood, or plys, which are laid in opposite directions to one another. This creates a much more stable and structurally sound sheath that can be used over the exterior.

How thick should plywood be for exterior walls?

3/8-inch
The International Residential Code specifies 3/8-inch plywood for sheathing walls with a standard stud spacing of 16 inches, if the siding is nailed to the studs through the sheathing. If the nails penetrate the sheathing, but not the studs, the minimum plywood thickness that the IRC designates is 1/2 inch.
