no-sheen, natural-look sealer maintains the color and character of stone while allowing moisture vapor transmission. “We like to use Sealer’s Choice to prevent damage by other trades during construction. It’s used as a protectant on about 90% of our jobs and those have fewer callbacks,” offered McCandless. “Sealing per the contract docu- ments is a big benefit.” Sustainable building with the Emerald System™ Custom Building Products is com- mitted to environmental responsi- bility in both product development and manufacturing practices. Over 100 CUSTOM Build Green® prod- ucts contribute to LEED certifica- tion with low VOCs, recycled con- tent and regionally sourced materi- als. CUSTOM’s Emerald System™ goes a step further, with products that are guaranteed to comply with environmental agency regulations. The Emerald System is also the first line of tile installation products to include Carbon Offset Credits that help reduce greenhouse gas emissions. ProLite mortar and Prism grout are cornerstones of the Emerald System™ and met the environ- mental standards of the Spectrum Towers’ builders with contributions to LEED® certification and Carbon Offset Credits. In addition, all of the CUSTOM products that were installed – plus the help of the Technical Services team – exceed- ed the performance expectations of the tile contractors.
