Quartzite vs. Slate: A Mineralogical Comparison for Premium Cladding
This technical analysis evaluates the structural and mineralogical trade-offs between Quartzite and Slate for commercial-grade cladding. It identifies mineral hardness (Mohs 7 vs. 3-4) and foliation risk as the primary predictors of stone longevity in high-traffic and freeze-thaw environments. By examining thermal stability thresholds (up to 300°F) and crystalline interlocking structures, this guide provides a standardized framework for architects and wholesalers to mitigate delamination liabilities and optimize material selection for 2026 international building standards.
