There’s no doubt that nearly every home in the UK has some sort of tiles installed either on the inside or outside of the property. Whether it’s in the kitchen, bathroom, or garden, the majority of homes use tiles as an effective, fashionable way to style a floor.

Whilst it’s understandable that homeowners choose tiles based solely around aesthetic reasons, it’s important to realise that most floor tiles are assigned a slip rating, known as an ‘R’ value, in accordance to the environment in which they should be installed. Tiles which aren’t assigned slip ratings are graded to a specific minimum standard regardless. R values span a scale from R9 (minimum standard) through to R13 (greatest slip resistance), which can be understood further in our handy graphic below.

Tile Slip Ratings Explained

The tile industry uses the draft informative index (ISO 10545) classification of ceramic tiles according to their slip resistance. This classification is chosen by examining tiles in both wet and dry conditions before they’re installed. An understanding of the measurement of the coefficient of friction and the importance of slip resistance for various types of slip-resistant tiles is vital to prevent and reduce the risk of slip-related accidents.

The Two Classes Within the ISO Standard:

  • CLASS 1 - <0.4 dynamic Coefficient of Friction
  • CLASS 2 - >0.4 dynamic Coefficient of Friction

Here is a breakdown of how the ‘R’ ratings explained in the graphic above fit into the COF classification.

R9 <0.2 COF

Mainly smooth, glazed tiles will record this low value when they are wet. Ideally, these tiles should only be used in dry areas and kept away from environments exposed to moisture.

R10 >0.2 COF <0.4 COF

Generally, only glazed tiles which are wet will show these values. Tiles with this classification can be installed in a variety of domestic spaces such as kitchens and living rooms.

R11 + R12 >0.4 COF <0.7 COF

Some glazed will fall into this category. If a tile has been assigned this COF as a minimum, dry and wet, it may be regarded as safe to be installed in domestic spaces such as bathrooms, kitchens, hallways, porches and living rooms, as well a public spaces such as swimming pools, shopping centres and airports.
