Wooden Tiles. Fortis Arbor Wood Mosaics are hand-cut from scraps of bamboo, teak, and rosewood left over from furniture-making. They’re 1„4 inch thick and either 1 inch by 1 inch or 1 inch by 2 inches. The mosaics are prefinished and intended for interior spaces with limited water exposure. The company also sells edge liners and circular inserts, and a grout designed to move with the natural expansion and contraction of the wood. Tile prices range from $37 to $45 per square foot.
