Understanding the Differences Between Glazed and Unglazed Porcelain Tiles
Porcelain tiles come in two main finishes: glazed and unglazed. The glazed variety features a protective coating that is baked onto its surface, enhancing stain resistance and offering a wide array of aesthetic choices. Conversely, unglazed porcelain boasts a more natural, matte finish, making it a popular option due to its slip resistance and durability, especially in high-traffic areas. While glazed tiles typically do not require sealing, unglazed tiles, being more porous, necessitate regular resealing to guard against moisture absorption and staining. Understanding these differences allows homeowners to make informed decisions regarding maintenance.
Differentiating Between Ceramic Tiles and Porcelain Tiles
Although ceramic and porcelain tiles are often confused, they exhibit distinct differences concerning density, water absorption, and overall durability. Fired at higher temperatures, porcelain tiles are denser and less porous than ceramic tiles. This quality renders porcelain especially suitable for regions frequently exposed to moisture, such as kitchens and bathrooms.
