Question: 1 / 50

How should exterior plywood wall sheeting be installed?

Long dimension parallel to studs.

Exterior plywood wall sheeting should be installed with the long dimension parallel to the studs for optimal strength and stability. This is because the plywood sheets will have more support and less chance of sagging when the orientation is parallel to the studs. Installing the sheets with the long dimension at a right angle to the studs (option B) or in either direction (option C) may result in weaker walls and potential buckling or warping of the sheets. Option D is only relevant for specific types of wall structures, so it cannot be considered a universally correct method for installing plywood wall sheeting.

Long dimension at right angle to studs.

Either direction is acceptable.

Right angle to studs on bearing walls parallel to studs on gable end walls.
