The Sultra patterned solid-surface wall panels and Sultrex quartz from One Source Group now meet Greenguard indoor air-quality standards and contribute toward up to four LEED points. Both surfaces are fabricated in the United States, reducing shipping energy, and are produced in more sheet sizes than stone or other solid-surface materials. Available in more than 30 colors and patterns, Sultra and Sultrex surfaces also meet NSF-51 standards for food applications, suiting them for both bathrooms and kitchens in commercial applications. www.one-sourc-group.com; 478.987.3185
