While the majority of glass tile manufacturers focus their efforts on decorative tiles, suited for walls only, there are a growing number of glass tiles suitable for residential and light commercial floor applications. Glass tile is now available in numerous sizes, shapes, colors, finishes, slip ratings and body strengths, all of which should be considered prior to specifying glass tile as flooring. Test results using the American Standard Test Method (ASTM) C 648 Breaking Strength test, which determines the amount of force it takes to break a tile (tile body strength) and ASTM C1028 test, which determines static coefficient of friction (slip resistance) provides insight into how a glass tile may perform in various environments.
An example of breaking strength, set by the American National Standards Institute (ANSI), is the minimum of 250 pounds of force for unglazed pavers. Glass floor tile with breaking strengths of over 800 pounds of force are now available. These high breaking strengths demonstrate that glass tile can be manufactured to the same performance standards as tile traditionally used in light commercial flooring.
