The Tile Alternative: It’s beautiful; it’s durable; it’s grout able – but it’s not ceramic. An expanded collection of Shapes and Sizes adds a new dimension of personalization to Armstrong’s popular Alterna™ engineered stone tile collection, an innovative alternative to natural stone and ceramic tile. Like stone and ceramic, it's incredibly beautiful and durable, but it’s warmer to the touch, feels softer underfoot and is easier to care for in any room of the home. Plus, multiple shapes and sizes provide a wide range of options for both floors and walls. Sizes include 16”×16” tiles and also feature select styles in 12”x12”, 12”×24”, 8”×16“and 8”×8”. Alterna is made with a durable composite material consisting primarily of crushed limestone. Manufactured in the U.S., Alterna is designed in Pennsylvania; the stone is quarried and assembled in Kankakee, Illinois and features more than 90% domestic content.
