GVT
GVT tile is made by exposing clay to searing hot temperatures — anywhere from around 2,300 to 2,400 degrees Fahrenheit! Unsurprisingly, GVT is sometimes called a “high-fire” material for this reason. Because it is made at high-fire temperatures, GVT tile is stronger than ceramic and can withstand more elements, which is why it often makes a great outdoor flooring choice.
GVT is hard and heavy like stone but also has some noticeable differences. For example, while stone is highly porous, GVT contains no pores at all, resulting in superior protection against moisture and humidity.
