SD Wall Panels operates a walk-in showroom and warehouse on Argent Street in Santee, supplying acoustic slat panels, PVC marble sheets, WPC interior and exterior cladding, faux stone veneers, and composite fencing systems to contractors and designers across Southern California. Stocked inventory ships same-day for local pickups or routes via LTL freight nationwide, a supply-chain speed that supports tight construction timelines alongside the electrical rough-in work handled by firms such as Copper Electric, Inc. on adjacent Prospect Avenue. The catalog includes bamboo charcoal wall panels engineered for moisture resistance in bathroom and kitchen applications, backed by fire-rating and acoustic-performance documentation the showroom provides for commercial permit submittals. Cut-sheet packages, trim-matching services, and on-site install coaching bridge the gap between material selection and finished wall, a coordination layer that complements the flooring-to-wall transitions managed by Village Flooring & Renovations on Magnolia Avenue. Large-format PVC marble panels span up to 48 by 96 inches per sheet, enabling full-height bathroom surrounds with zero grout lines and a Class A fire rating per ASTM E84.
