Frequently Ask Questions

With so many different styles and materials, how do I choose the right product?

There is no such thing as a "right" or "wrong" product, just the product which is best suited for your requirement. Therefore, it's a good idea to identify the requirements of your project first, then you can let yourself wander among the wide range of designs and colors, and select relying on your taste.

What is the most suitable product for outdoor laying?

For outdoor laying it is necessary to use tiles which absorb less than 0.5% water, "fully vitrified" according to international standards. All of the products in Naturgress, Irisgress and Irisstone, with water absorption of 0.04%, are completely frost-resistant and covered by a 50-year warranty, even for outdoor use.

Can floor tiles also be used for walls?

Yes, if the correct laying methods are used.

Which collections do you recommend for commercial installations?

All of the collections in Naturgress, Irisstone and Irisgress porcelain tile are covered by a 50 year guarantee against tread-wear, frost and stains, under any conditions of use.

What are the tiles made from?

Ceramic is primarily made up of clays, quartziferous sands, glass substances and other minerals. Only natural raw materials are used, mixed with water and fired at high temperatures to create a naturally beautiful product and to achieve hardness and durability.

What is porcelain tile?

Made from special clay minerals, porcelain tile (or porcelain stoneware tile) is a highly-resistant ceramic product with a solid structure and a hard surface which doesn't absorb water (classified as impervious), doesn't stain, and isn't affected by wear and tear over time.
All of the wall tiles and flooring in Naturgress, Irisstone and Irisgress are covered by a fifty-year guarantee against wear, frost and stains, under any conditions of use. Moreover, glazed porcelain tile requires lower maintenance than natural stone, granite and marble.

Are ceramic products environmentally-friendly?

Ceramic tiles are made from natural raw materials using the most up-to-date technology for safe-guarding the environment. Iris Ceramica has obtained both ISO 14001 and EMAS registrations which relate to eco-management, and periodically provides a statement of its environmental performance and its improvement programme. In 2004 the company's environmental commitment was awarded with the ANAB-IBO-IBN accreditation mark, reserved for materials approved to be used in sustainable architecture, for its Naturgress porcelain floor tiles.

Do tiles deteriorate over time?

The durability of ceramic tiles is superior to that of almost all the other surface finishes on the market. By choosing the most suitable product for your needs, taking due care during installation and cleaning regularly, combined with the manufacturer's experience, their long life is ensured.

What is meant by shade and calibre?

Ceramic is a natural material with a natural composition which becomes resistant when fired at very high temperatures. This process, however, can cause slight differences in the shades of colour and in the actual dimensions of a tile between one batch and the next. Therefore, tiles are grouped before packaging according to their shade and their calibre. These are then indicated on the label of every pack.

What are the advantages of ceramic floor and wall tiles?

Ceramic products are natural, beautiful, versatile, lasting, resistant, hygienic and easy to clean.

What are the advantages of porcelain tile?

The wide range of colours and textures, along with an accurate recreation of the look of natural stones, granites, slates, travertine, limestone, marbles, quartzite, terracotta and even wood and metal, combined with the low maintenance of ceramics and the technical properties of a hard-wearing material which is resistant to all weather conditions, chemical attack, scratches, stains, fading, heavy loads and fire.

What are the advantages of glazed ceramics?

The beauty and variety of colours, designs and decor made available by glazed tiles has always been one of the most valued qualities of ceramic products in general. The glaze also makes cleaning easier and hygienically more effective.

Glazed porcelain tile combines the aesthetical qualities and the ease of maintenance of ceramic tiles with the durability and surface hardness of its vitrified porcelain body, suitable for both commercial and domestic applications, indoors as well as outdoors.

Are ceramic products more or less expensive than other flooring materials?

Ceramic tile prices are competitive, especially if you take into account more than just the initial expenditure: adding up the cost of materials, installation, maintenance and possible repairs or replacements, ceramic tiles are the most economic material for floor, wall and façade covering.

Do ceramics require maintenance?

Only a minimum of effort is required to keep surfaces in good condition, due to the fact that glazed wall tiles and flooring are resistant to dirt and are not porous. If laid correctly and washed regularly with plain water, ceramic flooring will maintain the appearance and the specifications of the product over time, just like it was when installed. Furthermore, glazed porcelain tiles involve less maintenance than natural stones and marbles.

Can tiled surfaces be protected simply using common methods? Or is special treatment necessary?

After they have been laid, ceramic products do not require special treatment or cleaning with particular detergents.

Protection against abrasive dirt in entrance areas and against possible falling objects in the areas close to working surfaces is advisable, by means of floor mats.
We also suggest that you pay particular attention to protecting newly-laid flooring until all construction or remodeling work has been completed.

How do you calculate the quantity of tiles that you need to order?

Once the surfaces in question have been measured, we recommend that you increase the amount required by ten-fifteen percent to allow for waste from laying and future repairs.
