SPI - Stone Panels International LLC

Four decades ago, the firm that was to become Stone Panels International LLC (SPI) developed the world’s first natural stone composite architectural panels. Today, SPI under the StoneLite® brand, is the foremost domestic producer of top-quality natural stone composite panels and veneers and is a world leader in design and innovation. The SPI name is synonymous with superior quality, expert craftsmanship and dedicated customer service. StoneLite® panels offer architects and designers the freedom to select from wide range of limestone, sandstone, granite, marble, etc., sourced from around the world. Elegant stone finishes are able to be incorporated into extraordinary architectural details including curtain walls, rainscreens, cornices, balconies, cantilever structures, large free-span ceilings, soffits, curved structures, and more. SPI is the only lightweight reinforced stone supplier to gain acceptance by the International Code Council (ICC). The StoneLite® panel system is the only system currently accepted by the British Board of Agrèment and by French-based Avis Technique. StoneLite® panels’ strength and durability combined with their environmentally-friendly attributes make them a long-term smart choice. Stone Panels International LLC has shaped and continues to define the natural stone cladding industry.
