PEI Rating Explained: Choose the Right Tile for Every Traffic Level

PEI Rating Explained: How to Choose Tiles for Different Traffic Levels

Selecting the correct tile is more than just about color, finish or size. To know what type of flooring you should get and to know when you can expect it to still look good after being walked on for so many years, you need to know about PEI Rating.

Varying amounts of foot traffic are encountered in different rooms of the home, from the quiet sleeping quarters to the bustling commercial-like entryway. PEI tile rating is an indication of some of the glazed tile surfaces can resist to the abrasion and daily use.

But what do the PEI ratings really represent? Is a higher PEI really better? What PEI rating do I use for my living room, kitchen, bathroom or commercial environment?

Let’s break it down.

What Is a PEI Rating?

PEI rating is a rating system to indicate the durability of a glazed ceramic tile surface and how much wear and tear it can take from foot traffic and daily use. PEI is an acronym for the name of the organization Porcelain Enamel Institute, but the rating system is often debated when talking about glazed ceramic and porcelain tile.

The scale typically runs from PEI 0 to PEI 5, where 5 is the best in terms of protection against surface wearing.

But it is important to bear in mind that PEI is a rating that is geared towards surface abrasion resistance of glazed tiles. It doesn’t directly test for every characteristic of tile performance, such as slip resistance, absorptivity, breaking strength, or scratch hardness.

Consider PEI a single puzzle-piece in terms of tile selection, not the entire puzzle.

PEI Rating Chart: What Do PEI 0 to PEI 5 Mean?

Here is a simple PEI rating guide to help you understand the different categories:

These sections are intended to serve as a practical guide and not replace the manufacturer’s technical specification and installation advice.

PEI 0: Best for Decorative Applications

PEI 0 tiles are usually designed for areas where no walking abrasion is expected.

These tiles are best used on walls and in backsplashes, or any other surfaces that don't see a lot of foot traffic.

A busy floor covered in a low-abrasion glazed tile may develop some visible wear with time.

PEI 1: For Very Light Traffic

PEI 1 tiles are adequate for areas in homes or offices where minimal traffic is expected.

They could be used on the floor of a house in some limited areas in which you don’t wear shoes or bring a lot of dirt in. But on the whole, they’re not the go-to choose for high-traffic floors.

If your tile will be used in an area where there will be busy activity around the house, keeping a high PEI rating might be advisable.

PEI 2: Suitable for Light Residential Traffic

A PEI 2 is classified as light traffic.

This can allow it to be suitable for use in bedrooms or other comparatively peaceful home areas.

For the room that has a direct access to an entrance, or is heavily used, you might want to consider a higher abrasion class.

PEI 3: A Practical Choice for Everyday Homes

For many residential spaces, PEI 3 tiles provide a practical balance between appearance and everyday durability.

They can be considered for areas such as:

·       Living rooms

·       Dining areas

·       Bedrooms

·       Residential kitchens

·       General household flooring

If your floor undergoes typical daily traffic, PEI 3 is generally a sensible starting point in assessing glazed floor tiles.

PEI 4: For Heavy Residential and Commercial Traffic

In case a certain floor is subject to more frequent usage, then PEI 4 tiles are more appropriate.

They may be appropriate for high traffic homes and for some commercial or institutional applications when considering the full product specification.

Consider this category for areas such as:

• Busy residential entrances
• Offices
• Retail interiors
• Corridors
• Restaurants and similar spaces

But busy schedules do not imply that PEI is the only standard you need to scrutinize. Slip resistance, tile strength, surface finish, quality of installation and maintenance are also important.

PEI 5: Designed for Very Heavy Traffic

PEI 5 tiles are considered the highest rated in the scale and are intended for use on surfaces which are subjected to extreme wear.

They might be suitable for challenging commercial applications such as active public spaces, retail environments and high-traffic educational or institutional spaces.

Commercial applications Please note that in commercial applications always check with the tile manufacturer for approval of the tile for your intended use and do not rely solely on the level of the PEI.

Does a Higher PEI Rating Mean Better Tiles?

not necessarily true.

A higher PEI rating does not mean that a tile is suitable for every application.

To give you an idea a bedroom doesn't need the same level of abrasion resistance as a busy retail shop. Selecting the right specification for the environment is more important than just going for the highest number.

You should also evaluate:

• Slip resistance
• Water absorption
• Breaking strength
• Surface finish
• Shade variation
• Tile size and thickness
• Installation conditions
• Expected maintenance
• Indoor or outdoor application

The best tile is the one whose complete performance characteristics matches the space.

PEI Rating vs Other Tile Specifications

A common misconception about PEI is that it measures the overall durability of a tile.

It doesn't.

The PEI rating is concerned with how the tile coves to visible surface rubbing on glazed tile. Yet Other technical features answer other questions.

For instance, Mohs hardness signifies scratch resistance; DCOF relates to slip resistance (under certain testing conditions). Water absorption shows how much water a tile takes to absorb, and breaking strength deals with mechanical performance.

This means that two tiles with the same PEI rating can still behave differently in practical situations.

The Smart Way to Select Floor Tiles

A great tile looks good in your home — but also needs to be right for the way you live in your space.

With the knowledge of the PEI ratings for floor tiles you will be able to filter your options on the basis of traffic area. From the least trafficked bedrooms to the most trafficked commercial spaces, knowing which abrasion classification is best for you can help you make a smarter flooring purchase.

At Firedclay, the mission is clear: to bring more footage of tile knowledge, use ability and design insight into your shopping. Read the technical data from the manufacturer before you buy and select a product that is suitable for your particular application.

Because the right tile isn't simply the one that looks beautiful—it is the one that performs beautifully where you need it most.
