Is it better to install drywall vertically or horizontally?
Horizontal hanging reduces the lineal footage of seams by about 25%. Keeping the footage of seams to a minimum will result in less taping and a better looking finished job. Hanging horizontally also allows the drywall to flow over the framing so that bowed studs create less of a problem.
Is it better to nail or screw drywall?
While nails tend to be more flexible and hold up better against shear pressure—or lateral force—screws have much better grip and tensile strength, which ultimately keeps drywall from pulling away from the studs. When it comes to holding power, screws simply can’t be beaten.
