When installing vinyl siding vertically, what is the maximum horizontal spacing between fasteners?

• A. 8 inches
• B. 12 inches
• C. 16 inches
• D. 20 inches

Answer: (B)

When vinyl siding is installed vertically, it needs to be secured often enough to resist wind and keep the panels from sagging as they expand and contract with temperature changes. The maximum spacing between fasteners is twelve inches. If you go farther apart, the panel can bow or pull away over time, leading to loose edges or nail pops. Spacing closer, like eight inches, is more labor-intensive but still acceptable; however, the design standard sets twelve inches as the limit to balance security with proper expansion. Remember to fasten through the nailing hem and leave a small gap for expansion to prevent buckling.
