How to Choose Tiles with the Right PEI Rating: A Practical Guide for Interior Design Projects
When specifying tiles for an interior design project, it’s not just about selecting a beautiful surface — it’s about choosing tiles that perform reliably over time. That’s where understanding the PEI rating comes into play.
At Kimgres, we believe exceptional spaces are built with tiles that effortlessly balance aesthetics and durability. Whether you’re designing a bustling retail store, a contemporary office, or a luxurious home, the PEI surface rating ensures your tile selection meets the functional demands of the space.
What is the PEI Rating?
The PEI rating (Porcelain Enamel Institute rating) measures a tile’s abrasion resistance — how well it withstands foot traffic, friction, and daily wear. This tile durability scale ranges from Class 1 to Class 5, with higher numbers indicating stronger, more resilient surfaces.
The PEI test uses an Abrasimeter, in which rotating steel ball bearings and alumina powder are applied to the tile surface in a controlled chamber. The number of revolutions before visible wear appears determines its PEI classification.
Matching the right PEI-rated tile to the appropriate environment — whether it’s a high-traffic shopping mall or a serene guest bathroom — helps prevent premature wear and enhances long-term performance.
Breaking Down the PEI Scale
Here’s what each PEI class means when selecting tiles:
PEI 1 (Very Light Traffic)
Best for walls or very low-use areas like guest bathrooms and ensuite spaces. These tiles focus on aesthetic appeal over wear resistance.
PEI 2 (Light Traffic)
Suitable for residential areas with minimal abrasion, such as bedrooms and bathrooms. Ideal for spaces with soft-soled footwear.
PEI 3 (Medium Traffic)
A versatile option for residential floors including kitchens, living areas, and balconies. A great balance of beauty and durability.
PEI 4 (Heavy Traffic)
Designed for frequently used spaces like corridors, lobbies, and busy kitchens. Suitable for both residential and light commercial use.
PEI 5 (Extra Heavy Traffic)
The most durable option. Ideal for high-traffic commercial spaces such as airports, shopping centres, restaurants, and public walkways.
Which PEI Rating Is Best for Commercial Use?
For commercial spaces, the right tile must go beyond looks — it needs to stand up to heavy wear.
As outlined above:
- PEI 4 is suitable for light commercial use, such as offices, hotel lobbies, and boutique shops.
- PEI 5 is recommended for heavy-duty commercial applications, including airports, malls, and busy restaurants.
Choosing the correct rating from the start ensures lasting performance, fewer repairs, and a better experience for your clients.
Why Choosing the Right PEI Rating Matters
Selecting the correct PEI rating ensures your tiles aren’t just visually stunning — they’re built to last. The benefits of making the right choice include:
✅ Preventing early replacements due to wear or damage
✅ Reducing maintenance costs over time
✅ Ensuring long-term beauty and surface integrity
✅ Upholding your reputation as a detail-oriented designer, architect, or builder
