RigidStack™ – Lap Siding & Shake Siding

RigidStack™ Technology on Diamond Kote® Lap and Shake Siding delivers superior strength and alignment for a flawless finish. This innovative system uses a built-in spline to lock boards together, creating a rigid connection that resists buckling and maintains straight lines across the wall. Contractors benefit from faster, easier installation with reduced need for face nailing, while homeowners enjoy enhanced durability and long-lasting beauty. Combined with Diamond Kote’s prefinished surface and 30-Year No-Fade Warranty, RigidStack ensures a premium look that stands up to harsh weather and everyday wear—making it the ultimate solution for performance and precision.
