Several aesthetic considerations naturally come to mind when embarking on a tiling project, such as colour, shape, and design. These elements play a significant role in determining the overall look and feel of the space.
However, one critical factor that is often overlooked, but equally important, is the slip resistance of the tiles. This becomes especially vital depending on the area you are tiling, such as wet rooms, kitchens, or outdoor spaces.
This guide will help you navigate the complexities of tile anti-slip grading to make an informed decision.
The Importance of Slip Resistance
Slip resistance refers to the ability of a tile surface to prevent slipping, especially when the surface is wet or subjected to foot traffic. In areas like bathrooms, kitchens, and wet rooms, the risk of slipping is inherently higher due to the presence of water.
In commercial settings, such as public showers or pool surrounds, the need for slip-resistant surfaces is even more critical, given the high foot traffic and the constant presence of moisture.
What Are Anti-Slip Gradings?
To assist in choosing the right tiles, manufacturers often provide an anti-slip rating for floor tiles. This rating is commonly expressed as an ‘R’ value, which stands for ‘ramp test’.
The ‘R’ value measures the angle at which slipping occurs on the tile surface during testing, ranging from R9 to R13.
This scale helps indicate the level of slip resistance the tile offers, with R9 representing the lowest slip resistance and R13 offering the highest.
The ‘R’ rating is a crucial indicator because it informs you about the suitability of the tile for specific environments. For instance, while R9 tiles may be perfectly adequate for a living room or bedroom. They may not provide enough slip resistance for a bathroom or kitchen, where water and moisture are more prevalent.
R13 tiles are recommended for consistently wet areas like pool surrounds and changing rooms, requiring maximum slip resistance for safety.
Breaking Down the Anti-Slip Gradings
To better understand how these gradings apply to your project, let’s delve into each ‘R’ value and its implications.
R9: <0.2 COF (Coefficient of Friction)
Tiles with an R9 rating have a coefficient of friction (COF) of less than 0.2. These tiles typically have a smooth, glazed, matt finish that, although visually appealing, offers minimal slip resistance when wet.
R9 tiles are generally suitable for living rooms, bedrooms, or dry areas of the home where the risk of slipping is low. However, if you are considering R9 tiles for a bathroom, it is imperative to take additional precautions.
R9 tiles can be slippery when wet. To prevent falls, always use a bath mat or towel on the floor when using these tiles in a bathroom.
The mat provides an additional layer of safety, reducing the risk of slipping on the smooth tile surface.
R9 tiles are not suitable for wet areas, but they offer versatile aesthetics and are a good option for dry spaces. Smooth, glazed finishes can elegantly enhance spaces like hallways or living rooms, where slip-resistance is less of a concern.
R10: >0.2 COF <0.4 COF
Tiles with an R10 rating have a coefficient of friction that falls between 0.2 and 0.4. These tiles generally feature a glazed matt finish, similar to R9 tiles, but with slightly better slip resistance when wet.
A small number of unglazed tiles may also fall into this category. R10 tiles are versatile and can be used in a variety of domestic settings, including kitchens, bathrooms, and living areas.
R10 tiles provide a decent grip in kitchens, making them a safe and practical choice for areas with frequent spills. They can also be used in bathrooms, but a bath mat should be used to prevent slips when getting out of the shower or bath.
Additionally, R10 tiles can be used in hallways or entryways, where they provide a balance between aesthetics and functionality.
For those looking for tiles that offer a moderate level of slip resistance without compromising on design, R10 tiles are a solid option. They are particularly well-suited for areas where both dry and wet conditions may be encountered, such as kitchens or bathrooms in residential settings.
R11 + R12: >0.4 COF <0.7 COF
Tiles that fall within the R11 and R12 categories have a coefficient of friction ranging between 0.4 and 0.7. These tiles are available in both glazed and unglazed finishes, offering a higher degree of slip resistance compared to R9 and R10 tiles.
With this level of slip resistance, R11 and R12 tiles are suitable for a broader range of applications, both in domestic and commercial settings.
In domestic environments, R11 and R12 tiles are ideal for wet rooms, bathrooms, and kitchens, where slip resistance is paramount. They are also suitable for larger spaces like porches, hallways, and cloakrooms, where both wet and dry conditions may occur.
The increased slip resistance of these tiles makes them a safer choice for areas that are frequently exposed to moisture.
People often use R11 and R12 tiles in commercial settings, such as communal showers, lavatories, and swimming pool surrounds.
These tiles provide a safe surface for high-traffic areas, where the risk of slipping is greater due to constant exposure to water.
Additionally, they are suitable for larger commercial spaces like shopping centres, airport concourses, hotel foyers, and public walkways. Porcelain tiles are suitable for outdoor use and provide a slip-resistant surface.
R11 and R12 tiles are versatile options for residential and commercial projects, providing both beauty and improved safety. They are a reliable choice for areas where slip resistance is crucial, without compromising on design.
R13: >0.7 COF
R13 tiles, with a coefficient of friction over 0.7, provide top slip resistance for commercial or residential projects, indoors or outdoors.
People commonly use them in places where slipping is a big risk, like around pools, in public showers, and in locker rooms.
In these settings, the constant presence of water and moisture necessitates the highest level of slip resistance to ensure the safety of all users. The R13 rating ensures peace of mind by preventing slips on the tile surface, even under the most demanding circumstances.
Use R13 tiles in residential areas where slipping is a risk, such as wet rooms or outdoor patios.
R13 tiles offer excellent slip resistance, making them practical for areas frequently exposed to water.
R13 tiles, though often used commercially, are ideal for residential projects needing high slip resistance and durability for safety.
Conclusion
When selecting tiles for your project, it is essential not to overlook the importance of slip resistance. While colour, shape, and design are important considerations, ensuring that the tiles provide adequate slip resistance is crucial for creating a safe environment. The anti-slip grading system, represented by ‘R’ values, provides a reliable guide to help you choose the right tile for your specific needs.
Understanding tile anti-slip gradings helps you make informed decisions for bathrooms, pool surrounds, or outdoor patios.
In summary, the right tile choice goes beyond aesthetics. It is about creating a space that is not only beautiful but also safe and functional. By paying attention to tile anti-slip gradings, you can achieve a balance between design and safety, making your project a success.
