\"Tiler<\/p>\n

To many people, buying tiles can seem like a super simple task. It is essentially all about finding a design that you love and looking for a way to install it in your dream house. A few other details, of course, need to be taken care of, like checking the tile size or comparing the prices of the tile designs. However, we often forget to look at some other details that deserve a considerable amount of time and attention as well. Two such aspects are the PEI rating and the <\/span>water absorption of tiles<\/span>. These terms might be familiar, as you may have read them on the packaging of the <\/span>tiles<\/span><\/a> or the catalogue; however, it is natural to wonder how they truly matter in the tiling ecosystem. These ratings help you understand whether a tile is suitable for use and how it is likely to perform in different conditions.\u00a0<\/span><\/p>\n

PEI Rating: Tile Wear and Use<\/strong><\/h2>\n

PEI stands for Porcelain Enamel Institute, and the <\/span>PEI rating of tiles<\/span> is commonly used to indicate the resistance of a glazed tile surface to scratches or wear. Basically, it helps homeowners get the answer to an important question \u2013 how good is the capacity of the tile to handle foot traffic? The rating is particularly relevant when you are choosing glazed <\/span>tiles for floors<\/span><\/a>, as different areas of a home experience different levels of movement depending on their purpose. A bedroom may have relatively light traffic, while an entrance, hallway or commercial space can witness a lot more.\u00a0<\/span><\/p>\n

Important information: Therefore, <\/span>tile grade meaning <\/span>isn\u2019t shouldn\u2019t solely depend on how good they look.\u00a0<\/span><\/p>\n

What PEI Numbers Mean<\/strong><\/h2>\n

PEI ratings are generally given on a scale. The higher the rating, the greater the resistance to surface wear. Lower PEI ratings are generally helpful for areas that are likely to experience lighter foot traffic, while higher ratings are better suited to spaces that see more frequent traffic. For example, a tile intended for a lightly used residential area doesn’t necessarily need the same abrasion resistance as one installed in a busy commercial setting. An appropriate <\/span>PEI rating for tiles<\/span> helps ensure that the surface is matched to the demands of the space.\u00a0<\/span><\/p>\n

Important information: A higher PEI number does not mean that the tile is \u201cbetter\u201d. It just means that the tile is more resistant to wear.\u00a0<\/span><\/p>\n

The PEI Scale Numbers<\/strong><\/h2>\n
