Next Floor’s Stonecast Expanse II collection brings a refined interpretation of oak-inspired SPC design, pairing warm, approachable visuals with a high-performance waterproof structure. With oversized 9" × 60" planks, enhanced color-washed bevels, and a softly varied grain, Expanse II emphasizes natural realism while staying unmistakably modern. The 20 mil UV-cured urethane wear layer provides long-term durability, and the attached acoustic cushion adds comfort and sound absorption underfoot.

This updated StoneCast construction maintains dimensional stability across changing conditions while delivering a quiet, solid feel. The NextPro™ double-lock angle-angle installation system makes Expanse II approachable for DIY and professional installs alike—secure, glue-free, and suitable for on, above, or below grade. With lifetime waterproof protection, lifetime residential wear coverage, and light-commercial performance ratings, the collection is built for homes that need beauty, warmth, and everyday reliability.

Why Expanse II Performs

Stonecast Expanse II is engineered as a waterproof floating floor with a 6 mm thickness, 20 mil wear layer, and color-enhanced four-sided bevels for added visual depth. The attached cushion provides comfortable footfall and excellent acoustic ratings (STC 65, IIC 72, HIIC 92). It is FloorScore Certified, phthalate-free, and made using 100% virgin PVC for consistent quality and stability.

Its performance profile—lifetime waterproof warranty, lifetime residential wear coverage, and up to 30-year commercial wear in moderate-traffic settings—makes it suitable for open floor plans, family homes, and light commercial spaces alike. The combination of ease of installation and robust testing compliance ensures a floor that looks elevated yet withstands real-world use.
