A tile is a manufactured piece of hard-wearing material such as ceramic, stone, metal, or
even glass. Tiles are generally used for covering roofs, floors, walls, showers, or other
objects such as tabletops.
Alternatively, tile can sometimes refer to similar units made from lightweight materials suchas perlite, wood, and mineral wool, typically used for wall and ceiling applications.
TYPES OF TILES :
Tiles are made of different materials : ceramic, porcelain and natural stone.
1. Ceramic tiles
2. Porcelain tiles3. Natural stone tiles
4. Metal tiles
5. Vitrified Tiles
6. Mosaic tiles

C.O.F. (Coefficient of Friction)
The coefficient of friction value represents the tile’s natural resistance to slip,
measured by the force required to move an object across the tile divided by itsweight.
Lower numbers: Indicate less friction: floor will provide less traction and be more
slippery.
Higher numbers: Indicate more friction: floor will provide greater traction and be
less slippery.
Recommended or Required Values C.O.F. greater than .50 – Recommended for
standard residential application
C.O.F. greater than .60 – Required for commercial applications

GRADEGrade is the numerical ranking that reflects tile quality.
Grade 1:
Highest quality. Recommended for walls or floors.Grade 2:
Similar to Grade 1, but with slight imperfections. Recommended for walls or floors.
Grade 3: Lowest quality. Thinner tile designed for walls, not floors. Floor tiles are
allowed on walls. Grade 3 tiles are not allowed on floors.
PEI Wear Rating Porcelain Enamel Institute (PEI) Wear Rating Indicates tile’s
resistance to abrasion; reflects suitability for floor traffic. Icon:
PEI I and II:
Lowest resistance. Not suitable for floors (walls only).
PEI III:Moderate resistance. Suitable for all residential uses.
PEI IV:
High resistance. Suitable for all residential and light commercial uses.
PEI IV+:
Highest resistance. Suitable for all residential and all commercial and heavy traffic
uses.

CERAMIC TILES :
• Ceramic” comes from the Greek term Keramos, meaning "a potter" or "pottery”.
• For the creation of all ceramic materials, one needs to bake a mixture of clays at a
very high temperature. A ceramic tile, therefore, is the resulting product, after amixture of clays have been treated appropriately, pressed, fired at a high
temperature and cut to size.
• A ceramic tile consists of two parts: the body, which is called the “bisque” and the
surface, which is called the “glaze”. Many people like to use ceramic tiles to make
flooring as it has many advantages.
• It tends to be extremely durable, and it is easy to clean, especially in situationswhere drains are installed in the flooring, it allows people to essentially clean the
area.
• Ceramic tiles are also available in glazed and unglazed form. Some unglazed tiles
can be custom-painted and re-fired to set the glaze, while others are ideal for
situations in which porous tiles are needed, such as when making garden walkways.
• Ceramic tiles come in a wide variety of colours, patterns, sizes, finishes and
textures. Glazed ceramic tiles are an obvious choice for walls in bathrooms,
kitchens and laundry rooms, but are also often used in reception areas and
conservatories. Unglazed ceramic tiles can withstand heavy foot traffic and are
often slip resistant.

Ceramic Water Resistance: Glazed ceramic flooring tiles have a protective layer that
rests over the material, making them impervious to water and stain penetration. They are
also naturally resistant to the ravages of high humidity conditions. These properties
makes them ideal for use in moist environments such as bathrooms or kitchens.
Unglazed ceramic tiles : will need to be sealed in order to protect their surface fromliquids. The grout lines in between ceramic tiles are also susceptible to moisture, and will
need to be sealed in order to make them impervious to water which can otherwise seep
down, weakening the installation and causing the growth of mold.
Durability: Ceramic flooring is extremely tough and the tiles are difficult to crack. A
quality installation can last for 10 - 20 years and longer if well maintained. If a single tiledoes crack due to a severe impact, the process of replacing that tile is relatively simple.
Maintenance: Ceramic flooring is fairly easy to care for. Dirt, stains, and liquids all rest on
the surface, allowing you to easily wipe or mop them away. Regular maintenance just
consists of sweeping or vacuuming with a soft brush attachment to keep the floor free of
dirt and loose debris. If set in stains do occur you can use most heavy duty cleaners
without having to worry about damaging the material.

PORCELAIN TILES :
• Porcelain tiles are ceramic tiles with a water absorption rate of less than 0.5 percent
that are used to cover floors and walls. They can either be unglazed or glazed.
• Porcelain tile is also made from clay but tends to be made using denser types of clay
than ceramic. Porcelain tiles are baked at very high temperatures for long periods oftime so that almost all the water is removed. This longer drying time makes porcelain
tile much harder and denser than ceramic.
• Features : Ceramic and porcelain tend to have different overall colorings and
appearances. Ceramic tile is known for its natural red terra-cotta finish, while porcelain
is usually white or grey. Although ceramic may be glazed to create different surfacecolors or designs, porcelain is usually left unglazed. White chips in the glaze can be
highly visible on ceramic tiles, whereas chips in porcelain are not as noticeable
because these tiles are the same color throughout.

• Durability : Porcelain can be expected to last longer than ceramic in almost any
application. It can withstand high levels of traffic and increased levels of wear and tear.
Ceramic is likely to chip or crack if objects are dropped on it, and the tiles are not
expected to hold up for as long as porcelain units. Ceramic should not be used in most
commercial applications, while porcelain can be used in light- or medium-duty
commercial projects in addition to residential.
• Uses : Both porcelain and ceramic can be used to cover walls, ceilings, countertops,
showers and backsplashes. Ceramic is designed only for indoor use, while porcelain can
safely be used indoors or out. This designation is due to the higher moisture content of
ceramic tile, which makes it more susceptible to freezing- and thawing-related cracks.
Porcelain has a lower moisture content and is less likely to crack due to freezing.
• Installation. Porcelain is very hard and durable, which can be a problem during
installation. Its dense nature makes it difficult to cut, especially when special shapes or
rounded edges are needed.

NATURAL STONE TILES:
This is the collective term for a number of products including travertine, marble, granite,
limestone and slate. Being natural these tiles produce some really stunning designs and
are very hardwearing, but can be porous and require treating or sealing before using.

METAL TILES :
Metal tiles are referred to as anything that is solid metal, a metal laminate, a metallic
glaze, a metal and resin composite or simply a tile that gives an illusion of metal with a
lustrous finish.

VITRIFIED TILES :
• Vitrified tile is a tile produced using vitrification. By this process the tiles created
have very low porosity. making it stain-resistant and strong. It is an alternative to
marble and granite flooring.
• Vitrified Tile is made by baking fine minerals like clay and silica, at extreme high
temperatures where the individual grains or particles melt and fuse make
a vitreous surface. Thus creating a single mass making them extremely hard with low
porosity.
• They are quite slippery and rather dangerous in the residential houses. Mostly these
are used in show-rooms , offices etc.
• There are distinctively many advantages of the vitrified tile as a prime element for
flooring and dados, compared to many other options available in the market. Vitrifiedtiles are machine-made products, therefore greater consistency in sizes, shades and
thickness, against variable sizes and shades of natural materials such as marble,
stone, cement tiles and so on.
• Vitrified tiles need practically no setting time, therefore, they are quick to use after
they are laid. Mosaic, cement or marble stone tiles need 48 to 76 hours to set before
they can be polished.
• Vitrified tiles have another advantage – they are pre-polished and do not need
polishing on site, which is generally a time-consuming and messy affair

TYPES :
Soluble salt vitrified tiles are screen printed and polished.
Double charge vitrified tiles are fed through a press that prints the pattern with a
double layer of pigment, 3 to 4 mm thicker than other types of tile. This process
does not permit complex patterns but results in a long-wearing tile surface, suitable
for heavy traffic commercial projects.Full body vitrified tiles have pigment in entire body (thickness) of the tile. This
makes chips and scratches less noticeable and make this an ideal choice for high
traffic zones, but the process significantly increases the cost.
Glazed vitrified tiles (GVT) have a glazed surface. They offer a wide variety of
design, art work and surface textures like wood grain, bamboo, slate or stone. This
is also an expensive process, but the cost is dropping as digital printing techniquesare introduced.

MOSAIC TILES :
• Mosaics come in a choice of ceramic, glass and natural stone, as well as more
unusual materials such as stainless steel and even real sea shell. They are usually
supplied on sheets that can be used whole or cut for borders and features to create
some stunning decorative effects.
• Tiles are generally defined by their size, mosaics tend to be less than 6’’ square.
Their composition is the same as a ceramic tile and they may be glazed or unglazed
on a mesh or as single tiles, clay, glass, vitrified or fully vitrified.

In the Indian tile mart, one can choose from H&R Johnson (India), SPL, Kajaria and Nitco. Others include Vermora, Bell
Ceramic, Gokul and Asian.
Wall tiles are 6-7mm thick, while floor tiles are 10mm thick; making them Rs.10-15 more expensive (tiles can cost anywhere
between Rs.30 per sq ft to Rs.5,000 per sq ft).
COST OF VARIOUS TILES
Vitrified tiles: Price ranges from Rs.30 to Rs.150 per sq ft.
Ceramic tiles:Price ranges from Rs.25 per sq ft to Rs.250 per sq ft, depending on colour, size and usage (for floors or
walls).
Porcelain tiles: Size is usually around 2ft x 2ft and price varies from Rs.25 to Rs.150 per sq ft, again depending on colour,
size and usage (for floors or walls). Besides, there are also tiles made out of stone, glass, mosaic and poly-vinyl chloride
(popularly known as PVC). Various processes are employed to make them anti-skid, scratch-resistant, acid-wash proof, anti-
stain, anti-bacterial and fire-resistant.
Terracotta tiles: Originally from Tuscany in Italy, these tiles do not discolour or show signs of wear and tear. However,
they're more expensive - Rs.50 to Rs.2,000 per sq ft.
Stone tiles: Cost ranges from Rs.100 to Rs.250 per sq ft. Some popular brands include Kajaria, Antique International, Astral
Corporation, Keramos, Natural Stone India, Nine Star Marbles and Universal Tiles.
Mosaic tiles: Cost ranges fromRs.40 to Rs.60 per sq ft.
Glazed tiles: Cost: Rs.65 to Rs.110 per sq ft.
Digital Tiles: Prices range from as little as Rs. 8 /Sq Ft per commercial tile to Rs. 20 per square foot. Generally, the more
tiles of a particular size, glaze, and ornamentation that are manufactured, the less each one will cost.
Metal tiles: The price is high Rs 1 000 to Rs 2 000 per sq ft

Metal tiles: The price is high - Rs.1,000 to Rs.2,000 per sq ft.
These are imported tiles, but prone to scratches. A less expensive, low-maintenance option is faux-finish tiles - ceramic tiles
with metallic finishes from companies such as Nitco, Somany and Kajaria, among others.
Leather tiles: They cost Rs.1,000 per sq ft onwards
These are made from vegetable-tanned cowhide and meant for luxurious, expansive spaces. But they are high-maintenance -
regular dusting, vacuuming or damp mopping and waxing (around twice a year) are a must. The size varies with design and
pattern.. You also get wooden tiles covered with a layering of leather that cost Rs.700 to Rs.1,100 per sq ft.
Glass tiles: Glass tiles cost Rs.1,500 to Rs.2000 per sq ft.
Apart from making rooms look brighter and spacious, they don't fade or scratch, and are relatively easy to maintain. Sizevaries with design and pattern.
