Low Porosity

What is Low Porosity?

When a tile absorbs little to no moisture to its dense internal structure, it is said to possess low porosity. Due to low porosity, various liquids such as water cannot pass through the tile surface which makes it act as an almost impermeable surface. Generally, a tile that has an absorption percentage that is 0.5% or lower is known as a low porosity tile.

Structure and Formation

To ensure low porosity, tiles are manufactured using special methods that make them compact, dense, and highly resistant to absorption. Major characteristics of low porosity tiles include:

• They are produced using high-temperature kiln firing and high-pressure compaction.
• The dense body composition of the tile is improved through vitrification which also reduces internal voids.
• Low porosity tiles have a dense surface structure and fewer pores than regular tiles.

This dense construction is what gives low porosity tile its reliability across both residential and commercial applications. The most commonly used low porosity tiles are porcelain, vitrified tiles, and glazed tiles.

Performance Properties

Low porosity tiles come with a wide range of performance benefits that provide the tile with longevity and durability. These properties make these tiles a good choice for demanding environments. Major properties include:

• Low Water Absorption: Reduces the amount of moisture entering the tile.
• Moisture Resistance: Reduces the risks of mildew and mold.
• Hygiene: The impermeable surface of the tiles limits contamination and is thus hygienic.
• Stain Resistance: Low porosity tiles are easy to clean as they resist major stains.
• Frost Resistance: The low absorption rate of these tiles also provides them resistance to freeze-thaw and other outdoor conditions.
• Chemical Resistance: These tiles are resistant to most household chemicals such as acids, oils, cleaners, etc.
• Durability: These tiles are highly durable and maintain their appearance and finish for a long time.
• Versatility: Low porosity tiles are highly versatile and find utility in:
  • Bathrooms, showers, and wet rooms
  • Outdoor areas such as patios, balconies, and facades
  • Pools and water features
  • Kitchens and backsplashes
  • High-traffic residential and commercial environments

Together, these characteristics make low porosity tile a dependable choice for both functional and aesthetic longevity.
