Mostly GVT & PVT are used in commercial spaces which are resistant to surface abrasions and scratches. Ceramic body with Glazed surface can also be used for commercial space. Large format tiles with stain and chemical resistant and with less porosity is preferable in this area. Tiles for Terrace or Weathering tiles: These are 300x300mm size tiles coated with specially prepared white glaze and are meant for laying on the roof. The temperature in Indian summers rises to more than 45degree Celsius. To manage this; cool roof tiles are meant for. This reflects more sunrays back into the atmosphere in comparison to reflection of sun rays by ordinary roof. They also have low emissivity and radiate the heat energy faster back in to the atmosphere. Cool roof tiles reduce the roof temperature by 10 to 20 degrees and the resulting advantage percolated inside the building making power consumption lower. These tiles can be laid on all the surfaces; whether horizontal or vertical where sun rays fall on them.
