The Flash Bars series is a ceramic wall tile with a glossy finish glaze. Designed to emulate hand-crafted tile, Flash Bars is unique in that each tile is scored to look like several small tiles. Plus this makes for easy installation and grouting. Please note, a joint of 1/16″ is recommended due to the scored nature of the material. To ensure correct alignment of joints, it is recommended that all pieces be placed in the same direction. To do this, on the back of each individual tile there is an arrow indicating orientation of the tile.
