GVT and PGVT tiles are types of ceramic tiles that are commonly used in residential and commercial construction projects. GVT stands for Glazed Vitrified Tiles, which are tiles that have been glazed to give them a glossy, reflective surface. GVT PGVT Tiles are created by firing a mixture of clay, quartz, and feldspar at high temperatures to form a strong, durable material. PGVT stands for Polished Glazed Vitrified Tiles, which are similar to GVT tiles but have been polished to give them an even more glossy and reflective surface.
