The tile industry continues to evolve, and one thing in particular that is noticeable is tile sizes are getting larger and thicknesses are getting thinner. There have been several tile manufacturers who have been at the forefront of these latest product developments, but others are now catching up. With tile pieces now as large as 5 x 10 feet and 3 to 6 mm thicknesses, they are offering architects and designers alternatives to stone slabs.
Since the rise in popularity of these large tile pieces, it became clear to industry leaders that standards need to be set. There were even debates as to what to call these new large panels. It has finally been decided that they will be referred to as "Thin Porcelain Tile" — TPT for short.
