01. What are the various types of tiles?

The term tiles can be mystifying. Mostly tiles that are made from clay or a combination of clay and other materials, then kiln-fired, are considered to be a part of the larger classification called "Ceramic Tiles". Such tiles can be split into two groups, porcelain/vitrified tiles and non-porcelain/vitrified tiles. The non-porcelain/vitrified tiles are frequently referred to as ceramic tiles by themselves, separate from porcelain/vitrified tiles.

Ceramic tile (non -porcelain/vitrified tiles) : Ceramic tiles are generally made from red/white clay fired in a kiln. Ceramic tiles finished with a durable glaze which carries the color and pattern. These tiles are used in both wall tiles and floor tiles applications, softer and easier to cut than porcelain/vitrified tiles and usually carry a PEI 0 to 3 of rating. These types of ceramic tiles are usually suitable for very light to moderate traffic and generally have a relatively high water absorption rates that makes them less frost resistant and they are more prone to wear and chipping than porcelain tiles.

Porcelain/Vitrified tiles : These tiles are generally made by the dust pressed method from clay which results in the tiles that are dense, impervious, fine grained and smooth, with a sharply formed face. Porcelain/Vitrified tiles normally have a much lower water absorption rate (less than 0.5%) than ceramic tiles which makes them frost resistant or frost-proof. Different types of porcelain/vitrified tiles are:

Nano polished vitrified tiles : If you apply a layer of liquid silica on vitrified tiles then it fills the micro (nano) pores on the tiles surface and makes it smooth. These tiles are called nano polished vitrified tiles.

Double Charge vitrified tiles are fed through a press that prints pattern with a double layer of pigment; they are 3 to 4 mm thicker than compared to other tiles. This process does not permit complex patterns but results in a long-wearing tile surface, suitable for heavy traffic and vast commercial projects.

Full body vitrified tiles have pigment in entire body (thickness) of the tiles. This makes chips and scratches less visible and gives an ideal choice for high traffic zones, but the process considerably increases the cost.

Matt Porcelain Glazed Tiles / Glazed Vitrified Tiles (GVT) are glazed surfaced tiles. They offer a vast variety of design, art work and surface textures like wood grain, bamboo, slate or stone. This tile is now printed through digital printing technology.

Polished Porcelain Glazed Tiles / Polished Glazed Vitrified Tiles (PGVT) are similarly the GVT tiles in glossy form.

02. What is a glazed wall tile?

Glazed wall tiles are ceramic tiles that have a high absorption of water with one side that is glazed. They are perfectly suited to interior walls.

03. What is "digital technology" in terms of tiles?

The term digital technology refers to the tiles design that is printed onto the surface. Today, images that are created from photographs using a computer program are then applied to the tile by use of ink jets, much like modern office printers. With such technology usage, the designs are more exciting and attractive than ever.

04. What are glazed and unglazed floor tiles?

Glazed floor tiles are coated with a glassy finish which often contains color, texture, or design and is fired at significantly high temperatures. Unglazed floor tiles do not have such surface as the color forms from the body within the tiles. It can be natural color from the clay or other minerals and can be added to the mixture before forming and firing the tiles. Because the color extends through the complete tile, these are great for high traffic areas as they do not show wear as easily.

05. Can porcelain/vitrified tile be advisable under floor heating?

Porcelain/vitrified tiles material are perfectly apt to be used with under floor heating. The notable thing that should be taken into account is that a grout joint of at least 1.5 mm is requisite for the installation.

06. Can ceramic tiles fit to be used for outdoors?

Ceramic tiles can absolutely be used outdoors; we recommend that the tiles must be frost proof and unglazed to be used on floor. Make sure the absorption rate is 0.5% or less.

07. Can tiling right over plywood be done?

It can completely be done on a daily basis. However, you really need to know some more information. There are further more steps you needed to take care of when using backer board (CBU– cementitious backer units) as your underlayment. The thinnest you use, how you lay your plywood, how you SCREW it down, even the species and the rating of the plywood used, all makes a difference.

08. Can floor tiles be used on the wall?

Floor tiles can be used on the wall, but similarly wall tiles are never recommended being used on floor.

09. Can new tiles be fitted on an old tiled floor?

Yes, it is absolutely feasible to fit new tiles on top of an old tiled floor. However, it is not advisable as there’s a higher cost and you would possibly reduce the headroom (height between the floor and the ceiling). However, if you still want to go ahead for tiling on an old floor tiles, be careful the existing surface provides a good grip. If flooring is of glazed tiles then they have to be roughened to give a good grip to the new floor.

Furthermore, there are some other aspects as well that you have to take into consideration before deciding to fit new tiles on an old tiled floor. You need to allow the thickness of the tiles that you are laying in addition to approximately 6-12 mm for the cement slurry/adhesive, depending on the type of flooring to be laid. After adding thickness top of your existing floor, you can still be able to open doors.

10. What are the various types of fixing tiles?

The tiles can be either dry fixed tiles or wet fixed tiles. The dry fixing tiles are fixed by using conventional cement mortar. Wet fixing is done by using special adhesives that can fix tiles directly on the existing flooring.

11. Where can tiles be used?

Tiles can be used in almost any part of the house like hall, bathroom, kitchen, bedroom, portico, foyer, drive way, drawing room, living room, lobby, etc. There is also a prominent use of tiles for commercial and corporate places. They can be used both on the walls and floors.

12. What's the best way to calculate the quantity of Tiles?

Length * Width of the area to be covered will give you square footage. Most installations add 5-7% for cutting loss and is enough to keep on hand for any repairs. When the installation is on a diagonal or when you use a multi-size pattern, you should add 12-15%.
