|PEI IV||Tiles suited for all residential and light to medium commercial areas.|
|PEI V+||Tiles suitable for heavy traffic and wet areas where safety and maximum performance are a major concern such as exterior hallways, food service, salad bars, building entrances, around swimming pools or shopping centers.|
