Natural stone tiles and slabs come with a specific natural quality but at a heavy price tag. That is why people prefer to have an engineered stone in the form of ceramic, porcelain, and vitrified tiles as a big alternative to costly marble and granite. When it comes to choosing any vitrified tile, the factor of controlled quality matters the most. Natural stone means natural quality, but engineered tiles are made with controlled quality in terms of design, pattern, surface, size, and thickness. These days, vitrified tiles are used for outdoor projects due to their low porosity, water resistance, and frost resistance. These tiles are of four different types, including soluble salt, double charge, full-body, and glazed. Let’s have a look at some of the technical specifications of vitrified tiles.
Vitrified Tile (Polished Porcelain Tiles)

The first and foremost aspect of a vitrified tile is the quality factor. It is assumed that vitrified polished porcelain tiles for the floor should be of the first quality.
- 1.When it comes to classifying vitrified tiles, you can put them under group B1a of the International Standard for ceramic tiles ISO: 13006.
- 2.The vitrified tile you are planning to buy for flooring and wall cladding purpose should be solid, impenetrable, waterproof, and frost resistant.
- 3.The water absorption capacity of vitrified tiles should be less than 0.5%
- 4.The flexural strength (Modulus of Rupture) of vitrified tiles should be more than 35 N/Sqm.
- 5.While buying vitrified polished porcelain floor tiles, focus on factors like color, shade, size, texture, and design.
- 6.It will be good if you opt for a size that is always more than 600mm x 600 mm/ 605 x 605 mm.
When it comes to the thickness, it is vital to stick to manufacturing specifications. If not, you should not buy a tile that is less than 8mm.
Heavy-Duty Vitrified Tile (Unpolished Porcelain Tiles)
If you are interested in buying heavy-duty vitrified unpolished porcelain floor tiles to add more gleam to exteriors, make sure you prefer to have 1st quality. Products.
The vitrified tiles you choose should be acid and alkali resistant, weather-proof, anti-skid, and abrasion-resistant. According to the International Standard for ceramic tiles ISO:13006 and EN 176 requirements, heavy-duty vitrified tiles should meet the following requirements:
- Abrasion resistance<204mm
- Flexural Strength>35 N/Sqm
- Moh’s Hardness>6
- Water absorption<2%
The ideal size of heavy-duty vitrified tiles should be of 300mm x 300 mm.
So, these are the important technical aspects of a vitrified tile that all buyers need to understand before making an actual purchase.
