What are ceramic tiles?

Ceramic tiles are flat sheets made from a mixture of clay, sand and other natural materials formed into the desired shape and size and then fired at a high temperature. They come in various sizes and with thicknesses of between 3mm and 20mm. Thanks to advanced production technologies, they are available in an almost unlimited variety of sizes, colors surfaces and decorative effects.

What functions do ceramic tiles perform?

Italian tiles essentially perform three different functions:

- Aesthetic, they are part of the interior design project along with the other finishing materials

- Technical, they are able to withstand the stresses produced by the people who use the spaces without suffering damage or deterioration

- Functional, they are hygienic and capable of effectively withstanding foot traffic, frost fire and the elements.

New photovoltaic functions, although these are currently limited to a niche market.

What is porcelain stoneware?

The term porcelain stoneware (also known as porcelain tile) refers to an extremely compact dry-pressed ceramic tile with excellent technical characteristics (high resistance to bending, scratching, abrasion, chemicals and weathering) and, in particular, extremely low porosity. During the firing phase (1000-1350 ° C) all porosity in the product has been eliminated, allowing it to be declared as fully vitrified.

What is full-body stoneware (UGL)?
Full-body stoneware is a product that shows on the surface exactly the colors that are throughout the whole body of the tile. This characteristic helps in rare cases when a tile splinters and therefore the aesthetic damage is kept to a minimum.
What is colored-body glazed stoneware (GL)?

Colored-body glazed stoneware is a product colored in the mixtures of the tile’s body and further enriched by applications of enamel on the surface.

What is 20 mm thick stoneware?

20 mm thick porcelain stoneware is a highly durable product designed for external flooring of public and residential spaces: town squares, pavements, walkways, parking areas, terraces, poolsides, bathing facilities, public parks, and more.

The increased thickness (2 cm) as compared to traditional stoneware (1 cm) and heightened technical performance guarantee timeless durability and no risk of breakage. It has greater anti-slip characteristics and is easy to clean, maintaining its texture and colour over time.
What is a single fired white-body tile?

This describes a glazed tile, where both tile and glaze are fired together at a temperature exceeding 1000° C: the resulting product presents good resistance to abrasion and the wear of foot traffic. It is therefore suitable to be used as flooring. Single firing can also be in white paste (richer in feldspars and kaolin) or red paste(containing greater quantities of iron).

The technical features of single firing make it suitable for floor and wall tiles in private homes, where the level of resistance of the materials more than guarantees the life time of the product. On the other hand, in spaces used for other purposes such as shops or establishments that are open to the public, where foot traffic is more intense and the tile is exposed to greater stress, it is preferable to use a product having a greater level of resistance (glazed or polished porcelain stone).

What is shading?

The phrase “shading” is a denomination which means a passage of visible chromatic gradations that cannot be harmonized. It indicates the difference of tone of single tiles that are not homogeneous. Classes of shading have been established within which the different collections of grès porcelain tiles are classified:

V1= uniform

V2= slight

V3= moderate

V4= strong.

What is the surface finish?

'Surface finish' defines the texture of the surface of a ceramic piece and the process adopted to obtain it.

The matt (or natural) finish is the most versatile version in which the tile is not subjected to any other process after the cooking; the polished finish enhances shine and elegance; the structured effect simulates a process performed with specific tools that give the surface a rough and rustic effect; this finish makes the surface non-slip for use in wet environments and particular environmental conditions as well as for outdoors use.

What is tone?

Tone is the tonality of color that characterizes a particular lot of tiles. Considering that it is almost impossible to produce pieces with identical chromatic tonality in an industrial production, the tiles are grouped together regarding the homogeneity of color (tone) before being packed.

What types of edging can gres porcelain tiles have?

Gres porcelain tiles can have three different types of edging:

- natural (NAT): edging that comes exclusively from the molding of the press;

- rectified (RECT): edging perfectly straight (sometimes accompanied by a slight chamfer around the perimeter of the surface) coming from squaring procedures that bring the pieces to a uniform dimension of the sides, independent of productions lots;

- aged: edging that replicates a random irregularity by mechanical processing after the firing.

What is the tile's work size?

The work size is the manufacturing dimension of tiles. Due to manufacturing technology reasons, the porcelain tiles leaving the kiln may be of slightly different dimensions. Therefore, during the grade sorting stage, they are divided and grouped into batches of the same dimensions, according to the standards tolerance provided for by specific regulations. The work size is displayed on the pack.

What is a grout line?
A grout line is the distance that separates one tile from another.
Is it possible to install tiles with no grout lines?

No, the grout line is a necessary distance that permits dilation of the floors and natural settling due to structural movements, humidity, and variations in temperature. Depending on the tiles’ type of edge, it can be very thin (1 mm) or very wide (5 mm). The laying of tiles generally varies according to the characteristics of the collection itself. If the tiles are rectified (the edge is perfectly straight), they can be laid with a minimum grout line of 1 or 2 mm for a sophisticated and elegant look. The final result is quite striking and is generally recommended for modern and highly technical products like the large formats. In the case of more traditional or rustic tiles, in which the borders are not perfectly straight, a slightly wider grout line of approximately 4 mm is generally recommended so that the end look remains in keeping with the aesthetic and functional characteristics of the tiles themselves.

Where should we dispose of waste materials left over after installation?

Even though the waste products from the demolition of tiles are “inert” materials (non-reactive, chemically and physically stable, resistant to prolonged exposure to extreme thermal, hygrometric, and chemical conditions), we recommend bringing the waste to the recycling point nearest you for proper and environmentally sustainable disposal.

Where do Panaria’s products come from?
Panaria’s products are designed and manufactured in Italy. Italian ceramic is recognized worldwide as a symbol of excellence, quality, and technological innovation.
Are Panaria’s products fire resistant?
Yes. The fire resistance of materials is typically expressed in classes. Ceramic materials are in Class A1 (non-combustible products).
Is porcelain stoneware suitable for installation on heated floors?

All Panaria Ceramica porcelain stoneware floors, by virtue of their great heat conductivity, which is equal to 1.3 Watt/m °K or 1.1 Kcal/m h °C (refer to EN 12524:2001 standard), are highly recommended for installation on heated floors.

What is the right number of tiles to order?
It is a good idea to order an average of 10-15% more tiles than needed for the total surface area to be covered. The amount should be carefully calculated at the time of order as a future order may not perfectly match the product previously used up until that moment.
How do I know if the tile I bought is really a first choice tile?

All the packaging of stoneware produced by Panaria indicate the choice of the tiles in the box. Therefore to be sure that your point of sales sold you first choice tiles, it is enough to control that on the box there is written “I” or “1°”. Depending on the collections, for flooring, decors or special parts, the first choice is indicated by the Arabic or Roman number.

Do the tiles deteriorate over time?
Choosing the product most suitable for the designated surface, care during installation, and regular cleaning guarantee the durability of ceramic products, which is greater than that of almost all other materials on the market.

What is the difference between ceramic tiles and other cladding/materials?


Thanks to its partially vitreous structure and high degree of internal cohesion, ceramic is hard and highly resistant to breakage and abrasion. These characteristics are governed by international standards (EN 14411 ISO 13006), allowing comparisons to be made on the basis of objective values. Refer to the packaging and data sheets far details or contact the retailer far further information.


Ceramic, especially vitrified ceramic, is a compact and non-porous material, making it impermeable and resistant to staining. This means that tiles are quick and easy to clean, as well as having good frost resistance.


Unlike many other materials, ceramic tiles are noncombustible, they do not release fumes or toxic gases in the event of fire and they have a flame-retarding action, thus reducing fire damage.


Today's ltalian ceramic tiles come in modular sizes with lengths ranging from a few centimetres to more than a metre, so purchasers can choose from an enormous range.


Ceramic is an inert materiai with a composition that prevents the release of any substances that are harmful far health. And unlike other surfaces and objects, they do not trap dust, pollen or germs, allowing them to be cleaned effectively so as to minimise health risks.

Is it possible to use porcelain stoneware/Panaria Ceramica’s products outside as well?
Yes. Panaria offers a wide range of products for exterior spaces, in both traditional thickness (1 cm) and larger thickness (2 cm). The texture of the surface, rough to the touch, ensures that it remains slip-resistant in the presence of water or under other specific environmental conditions.
Can Panaria Ceramica’s tiles be used in both residential and commercial spaces?
Yes. Panaria offers a wide range of products suitable for both residential and commercial spaces.
