Toyota wants to salute do-gooders by giving 100 cars over 100 days to organizations that could really use a new set of wheels. And voters like you decide who gets a new ride every day.
PEI is the abbreviation for Porcelain Enamel Institute. A PEI Rating is given to a tile product based the hardness of its glaze. This hardness is determined by the manufacturer using a standardized test.
While not required to do so by law, many companies will publish PEI ratings for each tile in the specification section of a product tearsheet. So, even if the tile company does not specify that a tile works for showers or floors or walls, you can still determine a tile's best installation location from the PEI ratings. Some tile companies in their informational literature do a good job of organizing tiles according to rooms or areas of the house.
