my take on Trav
Before purchasing your travertine tile, it is important to become familiar with industry terms in order to choose the type and grade of tile most appropriate for your purposes.There are three grades of travertine: premium, standard, and commercial. Premium grade, which is sometimes called first grade, is a tile that has been perfectly cut and has a uniform thickness throughout with very little filler. Standard grade, also called second grade, will also be perfectly cut with a uniform thickness, however, there will be a bit more filler in the stone. Commercial grade, also known as third grade, may not be perfectly cut on all sides and it will not have a uniform thickness. Additionally, there will be a great deal more filler within the stone.
