Understanding Tile Ratings and What They Mean

Introduction

When selecting tiles for your home, it’s important to understand tile ratings. These ratings provide valuable information about the tile’s durability, suitability for different applications, and more. Here’s a guide to help you understand tile ratings and what they mean.

1. PEI Rating (Porcelain Enamel Institute)

The PEI rating measures the tile’s resistance to abrasion and wear. It ranges from 1 to 5, with higher numbers indicating greater durability.

• PEI 1: Suitable for wall use only.

• PEI 2: Suitable for light traffic areas such as residential bathrooms.

• PEI 3: Suitable for medium traffic areas like residential kitchens and hallways.

• PEI 4: Suitable for heavy traffic areas, including residential and light commercial spaces.

• PEI 5: Suitable for heavy traffic areas, including commercial spaces.

2. MOHS Hardness Scale

The MOHS scale measures the scratch resistance of tiles. It ranges from 1 to 10, with 10 being the hardest (diamond).

• 1-4: Suitable for walls and low-traffic areas.

• 5-6: Suitable for moderate traffic areas.

• 7-10: Suitable for high-traffic and commercial areas.

3. COF Rating (Coefficient of Friction)

The COF rating measures the slip resistance of tiles. Higher COF values indicate better slip resistance.

• COF < 0.50: Suitable for wall use only.

• COF 0.50-0.59: Suitable for light traffic areas.

• COF ≥ 0.60: Suitable for general flooring, including areas that may get wet.

4. Water Absorption Rate

This rating indicates how much water a tile can absorb. It’s especially important for areas exposed to moisture, such as bathrooms
