The Porcelain Enamel Institute (PEI) rating comprises numbers ranging from 1 to 5, with Grade 1 being the least durable and Grade 5 being the toughest. For your porcelain floors, you would need at least a Grade 2 tile to maintain the look of your living space.
Porcelain tile is graded on a similar scale. The Porcelain Enamel Institute (PEI) has established ratings ranging from 0 to 5, whereas 0 represents the softest tiles suitable for wall applications and 5 represents the hardest tiles suitable for heavy foot traffic.
The grade of porcelain tile is affected by the mixture of materials used in its manufacture, but mostly the grade is determined by the tile's thickness. Thin, grade 1 tiles are not necessarily lower in quality than higher grades, they just have different uses.
The PEI rating, or Porcelain Enamel Institute rating, is one of the most important factors to consider when considering various porcelain tile grades for your project. This rating tells you the resistance of a tile to wear due to abrasion and determines its suitability for different uses.
Grade. Grade is the numerical ranking that reflects tile quality. Grade 1: Highest quality. Recommended for walls or floors. Grade 2: Similar to Grade 1, but with slight imperfections.
Tile Thickness
The vast majority of porcelain tiles are 6mm to 10mm thick and a tile in this range will serve most purposes. Wall tiles typically range from 6 to 10mm thick. Mosaics and decorative wall products also range from 6 to 10mm thick to make combining them easier.
The most obvious difference in the two is the finish. Lower quality porcelain may have a flaws in the glazing or glazing that does not cover fully. The most common flaw looks like tiny pinholes.
1. Lower quality materials: The tiles may be made from lower quality materials, which can affect their durability and longevity. 2. Mass production: The tiles may be produced on a large scale, which can lower the cost per unit.
Compared to other flooring materials, such as hardwood flooring, natural stone, or vinyl tile, porcelain tile can be less comfortable underfoot due to its hardness. It's colder to walk on, especially in the winter.
Porcelain tiles are one of the most practically designed tiles that are not strong but aesthetically perfect. They do not chip easily and the cases of such damage, if any, are very rare and most can be avoided with extra care.
One of the things to consider before buying tiles especially Porcelain tiles is its design, colour and size. A good Porcelain tile assures a colour consistency throughout its design and with its long-lasting property the choice of design and colour should perfectly compliment your personality.
Best for Cost: Ceramic Tile
As a general category, ceramic tile is less expensive than most porcelain tiles. But there is a surprisingly large range of prices for both types of tiles. Note that the very highest quality designer tiles tend to cost roughly the same for ceramic and porcelain.
V2 – SLIGHTLY noticeable from tile to tile.
The range of colours and tones within the same shade is slightly noticeable from tile to tile. There are clearly distinguishable differences in design texture or pattern with similar or slight change in colour tones.
The different grades of ceramic tiles – Grade 1 are usually placed on walls, grade 2 are usually for homes flooring; grade 3 is for light to moderate foot traffic; grade 4 is usually for commercial use; grade 5 is for heavy foot traffic.
Tiles with a PEI rating of 4 are suited for installations that are subjected to regular levels of foot traffic. Recommended for medium commercial and light institutional use, such as restaurants, hotels, hospital lobbies and corridors.
When tiles have size, shade and quality variations in them, they are labelled second, or B grade and come with no guarantees from the manufacturer or retailer. They may be cheaper than a first grade tile, but you need to check each one before installing to avoid any nasty surprises in your finished project.
Porcelain or ceramic tile
Both porcelain tile and ceramic tile are made to sustain decades of high-traffic wear and tear. If installed and maintained well, they can last 50 years or more! Porcelain and ceramic tile are also fairly resistant to elements like water, debris, and stains.
Porcelain tile has a 60+ year life expectancy, so you definitely get your money's worth. It's perfect for walls, floors and indoor/outdoor installations. Rated for high-traffic areas, you won't have to worry about your porcelain floor degrading over time.
The surface of porcelain and ceramic tile do not require sealing, however, it's important to note that even though your porcelain or ceramic tile does not need to be sealed, the grout used during installation will need to be sealed and maintained.
– Simply put: no! Among tile options, porcelain stands out as a very strong and durable choice.
It comes in various styles, colors, and sizes and can be used to create stunning designs. Porcelain tile is typically mid-range in price, costing an average of $12–$40 per square foot.
However, you might be wondering how slip-proof they are, especially if you intend to lay them around a hot tub. The good news is that porcelain tiles are naturally very grippy and safe to walk on even when wet; however, it's not as simple as that.
However, there are a number of factors that can affect the price of porcelain tiles such as the manufacturer, the country of origin, the depth/quality of the printing process, etc. But the thing that affects tile pricing the most is the design.
Thickness: Unglazed or full-body tiles are thicker and denser as compared to glazed porcelain tiles. Slip Resistance: Due to liquid glass coating on glazed tiles, they are lesser slip-resistant than a full-body tile.
Durability: The density of porcelain tile makes it more durable than ceramic tile while being less subject to wear and tear. This makes it more suitable for commercial use as well as in the home. Water Resistance: Porcelain tile is almost impervious to water compared to ceramic tile.
