Quartzite is formed based on high heat and compression within the earth. This material is commonly used in floor, wall, and staircase installations. Since this material has been formed under extreme pressure and heat, the material becomes highly scratch resistant in comparison to the other major tiling options. The formation process all makes this material super dense and durable. Most of this material is cut to one half – one inch thick pieces. It’s very important to understand the weight load when installing on any second level or load rated engineered building. Quartzite ranks at 7 on the hardness charts. All the Quartzite aspects are similar to Marble with the added benefit of being scratch resistant. However, just like Marble, Quartzite looks it’s best when highly polished in a shiny condition. Since its best state is when Quartzite Floors are shiny, it’ll be very slippery if it’s installed around pools, bathrooms, and spas.
