The NSAR line of natural and engineered stone products are made from granite and slate. The product line includes natural and engineered stone veneers, mosaics and pavers in a variety of colors and tones. What's the difference between natural and engineered stone? The natural stone products are cut directly from larger pieces of granite and slate. The engineered stone uses a polyesther resin to bind a fine mix of natural stone materials to form shapes. NSAR veneers can be used for commercial, residential, interior or exterior applications, on floors, walls, kitchens, bathrooms, entryways, fireplaces, even the pool. NSAR products offer flexibility in architectural and decoration applications.
