, a Tile of Spain–branded manufacturer, developed the Limestone collection
of ventilated façades as a multifunctional tile product suitable for floors, walls, interiors, and horizontal and vertical exterior surfaces. According to the company, the porcelain tiles are two-and-a-half times more resistant to the elements than granite and four to five times more than marble. The frost-resistant material also maintains a low +/-0.02 percent water absorption. The tiles are cut with a nonbeveled edge and at a uniform size for tighter grout joints and compatibility with other Apavisa series and Limestone colors, which include marfil, beige, siena, gris, and grafito.
