RigidStack siding features an integrated spline system that locks each board to the next, forming a strong, unified wall assembly that's up to 375% stronger than traditional lap siding and installs 20-25% faster. Because the boards interlock, face-nailing is rarely required, resulting in no visible nail heads, fewer touch-ups, and a reduced risk of moisture intrusion through fasteners.
