Saltillo tile is categorized under which water tile rating?

Saltillo tile is classified as non-vitreous due to its porous nature, which allows for moisture absorption. This characteristic means it does not have a low water absorption rate, which is essential for a tile to be considered vitreous or impervious. Non-vitreous tiles typically absorb more than 7% of water, leading to higher vulnerability to moisture and environmental conditions. Recognizing the classification of Saltillo tile as non-vitreous is crucial for understanding its applications, installations, and maintenance in areas subjected to moisture. This distinction helps contractors and homeowners make informed decisions about where and how to use Saltillo tile effectively, ensuring longevity and performance in various settings.
