What Is A COF Rating For Tile?

Coefficient of friction, or COF, is an objective standard of rating how slippery an item is. Search COF ratings published by tile manufacturers and retailers. Look for higher COF slip resistance numbers. Dry, clean items that move against each other are usually COF-rated from 0.3 to 0.6.

What is a good COF rating?

Tile COF can be rated “wet” or “dry”. For a general floor, both ADA and OSHA require a dry rating of 0.6 and above for a dry floor to be considered “safe”. For a bath or kitchen, where the floor is likely to get wet, a wet rating of 0.6 or greater is required and 0.7 or higher is better.

What is a good coefficient of friction for tile? The Ceramic Tile Institute identifies tile in the following three categories: Slip Resistant: Coefficient of friction is 0.60 or greater (wet). Meets or exceeds general safety and health regulations, ADA and OSHA requirements. Conditionally Slip Resistant: Coefficient of friction is 0.50 to 0.59 (wet).

What is COF for tile?

10 Coefficient of Friction – Reprinted from ANSI A137. The coefficient of friction (COF) measurement provided in this standard is an evaluation of a tile surface under known conditions using a standardized sensor material prepared according to a specific protocol.

What is the difference between COF and DCOF?

What is the difference between COF, DCOF and SCOF? COF (Coefficient of Friction) is a numeric value that represents the amount of friction between two objects. DCOF (Dynamic Coefficient of Friction) specifically tests the friction of an object that is already in motion (kinetic).

What is grade 5 porcelain tile?

Grade 5. The toughest porcelain tile available on the market, Grade 5 tiles are used in areas that receive very high foot traffic and are prone to a lot of wear and tear. They are popular for installation in schools, hospitals, grocery stores, and industrial buildings.

Is porcelain tile slippery when wet?

Ceramic and porcelain tile floors can be notoriously slippery. … There is a reliable way to find out how slippery floor tile will be under both wet and dry conditions. It’s a slip resistance rating system called COF (or coefficient of friction) published by tile manufacturers.

What tile is not slippery?

Vinyl tile is a budget-friendly option, and some vinyl tile is slip-resistant. It is available in a wide range of colors, designs and patterns, and many styles feature a textured surface that provides effective traction. Vinyl can be customized to look like ceramic tile, wood, stone or other types of flooring.

Which is better glazed or unglazed porcelain tile?

Unglazed tiles are thicker than glazed tiles, and due to their density, chemical-resistance, and lack of porosity, they are better suited to areas with lots of moisture, such as washrooms, kitchens, and laundry rooms. In terms of safety, they are the better option.

What is better porcelain or ceramic tile?

Porcelain tiles are denser than ceramic, and therefore less porous. Meaning they’re harder, therefore more durable and absorb less water. This makes them more suited to high footfall areas which will see heavy use.

Is porcelain tile more expensive than ceramic tile?

Cost of Porcelain vs. … While both ceramic and porcelain are less expensive than most renovation materials, their price differences are due to their density differences. Porcelain tiles are therefore more expensive than ceramic tiles.

Which tile is best for bathroom?

Tile has always been a popular flooring choice for bathrooms. This is for a good reason. Porcelain tile is waterproof, cost-effective, and easy to clean. And with ever-growing options in color, texture, and patterns, there is endless variety.

Are porcelain tiles cold?

The high density of porcelain means it’s less likely to absorb moisture. They also do not crack due to cold and can even withstand freezing temperatures, which means they can be used outdoors to create a seamless look.

What does R10 slip rating mean?

R10 Anti Slip Rating – Options that possess R10 anti slip ratings will provide minor to moderate resistance to slipping, making them ideal for use in hallways, kitchens, and other living spaces including bathrooms.

What is anti slip rating?

So what do the anti slip gradings mean? The majority of floor tiles these days are given an anti slip rating. This rating comes in the form of an ‘R’ value. The ‘R’ stands for ‘ramp test’. This ‘R’ value ranges from R9, which has a small degree of slip resistance, right up to R13, which is the highest slip resistance.

What is PEI rating on porcelain tile?

“PEI” is the abbreviation for Porcelain Enamel Institute. A PEI Rating is given to a tile product based the hardness of its glaze. This hardness is determined by the manufacturer using a standardized test. The results of this test will determine the proper usage of a product.
