Choosing between Porcelain and Ceramic Tiles

Updated: Jul 10

Porcelain tiles and ceramic tiles are two of the most common types of tiles you can see in home renovation. What's the difference between the two? How do you select the right one for your kitchen and bathroom? To help you better understand porcelain and ceramic tiles, we will go over their differences based on water absorption, PEI rating and durability.


瓷质砖和陶质砖是我们在家居装修中最常见的两种瓷砖类型,但是这两种类型的砖块有什么区别? 您又应如何选择适合您的厨房和浴室的瓷砖呢? 在此,我们将根据吸水率、PEI等级和耐用性几方面为您提供瓷砖选择的一些思路。


Water Absorption 吸水性


Porcelain tiles have a lower water absorption rate than ceramic tiles. According to the American Society for Testing and Materials (ASTM C373), the water absorption rate of porcelain tiles is less than 0.5%, while it is 0.5%-3.0% for ceramic tiles. Porcelain tiles are denser, harder and more impervious to water than ceramic tiles. This means porcelain tiles

have the advantage over ceramic tiles in outdoor areas, wet areas and areas of high traffic, and some porcelain tiles can be used virtually anywhere. We suggest using porcelain tiles for flooring in the kitchen and bathroom areas while using ceramic tiles as wall tiles.


根据美国测试和材料协会(ASTM C373),瓷质砖的吸水率小于0.5%,陶质砖的吸水率为0.5%-3.0%。瓷质砖的吸水率低于陶质砖,瓷质砖密度更大,质感细腻,更难以透水。这意味着瓷质砖几乎可以在任何地方使用,甚至在室外,潮湿区域和高流量区域,这些特点是优于陶质砖的。由此可以总结,瓷质砖比陶质砖更坚硬,更不透水。所以我们建议在厨房和浴室的地板上使用瓷质砖,而陶质砖则可以作为墙砖使用。


PEI Ratings PEI评分


The PEI (Porcelain Enamel Institute) rating is an indication of tile hardness and a valuable guide to tile selection for different projects. The PEI rating includes six classes. Tiles in the lowest class, class 0, are technically unsuitable for underfoot use. They are usually used for light-duty on walls only. The highest class, class 5, is for heavy traffic with abrasive dirt. Typically with a less appealing appearance, it is mostly only used for flooring. The PEI rating for porcelain tiles is usually around class 5, while ceramic tiles are usually from class 0 to class 3.


PEI评级是瓷砖硬度的指标,它们是选择不同瓷砖的宝贵指南。 PEI等级从最低等级0(技术上不适用于地板的瓷砖)到最高等级5(能承受更大重力,磨蚀性污垢,耐化学性更高)。 PEI评级为瓷质砖等级为5级(承更大重力),PEI评级为0级至3级的陶质砖,但大部分陶质砖评级为下限。


Durability of tile 瓷砖的耐用性


Porcelain tiles are denser and more durable than ceramic tiles thanks to their through-body composition. While both porcelain and ceramic are heated, porcelain is processed at higher temperatures for a longer duration than ceramic. Also, porcelain has higher feldspar content, which makes it more durable.


瓷质砖不仅比陶质砖更细密,更由于它是完整一体的,因此被认为比陶质砖更耐用,并适合大面积使用。虽然瓷质砖和陶质砖都是用火烧制而成的,但瓷质砖在高温下烧制的时间比陶质砖长。此外,瓷器具有较高的长石含量,这使得它更耐用。所以,瓷质砖比陶质砖更耐用。
