Frequently asked questions
What is it TechniStone® ?
TechniStone® is a compact, hard, imporous, composite product supplied in the form of slabs, tiles, or special formats with a wide range of applications in private, public and industrial sector as kitchen countertops, bathroom vanity units, tables, window-sills, floor tiles, wall tiles, mosaics, etc.. Taking into account the used raw materials and production technology, TechniStone® achieves excellent properties due to its strength and compactibility. The wide range of color shades, surface finishes, thicknesses and sizes enables always to choose a suitable combination conforming to both esthetical and qualitative requirements.
What is TechniStone® made from?
TechniStone® is produced from high-quality natural raw materials (quartzes, granites), mirror and glass granulates, from a small amount of color pigments and quality polyester resin. More than 90% of the product mass is formed by natural components; therefore the content of the polyester resin is less than 10%.
Is TechniStone® the same throughout its volume or is its color and structure built only on the surface?
TechniStone® has homogeneous structure and color throughout its volume, the front and back faces of the product can be machined and polished, any holes and grooves can be milled, edges can be treated. The shade and the structure will be identical.
What is the comparison of TechniStone® (used e.g. on a kitchen countertop) to natural granite, marble, Solid surface or postforming?
TechniStone® has in comparison to natural granites higher flexural strength, at the same thickness is more resistant against e.g. impact and load. With the TechniStone® products (especially of the Granite range) you will get the feeling of granite, but with multiple times lower absorbability of the surface, which does not absorb food and drinks. TechniStone® is harder and more resistant than natural marble. Moreover, it is composed mainly of silicates, which are acidproof as opposed to marble.
TechniStone® , as opposed to the Solid surface or postforming products contains more than 90 % of anorganic materials. The TechniStone® surface is therefore far harder, more resistant and durable.
How can the individual types of TechniStone® be characterized?
TechniStone® is offered in four production groups which differ from each other by the used raw materials and consequently also by their appearance.
SAND (commercial name: Elegance, Gobi)
These products are made from sorted siliceous sands. The most significant characteristic is the fine, medium coarse texture and colors very close to shades of natural stone. Most of the input materials for Elegance Eco colors production comes from the Czech Republic.
Nature, inorganic components: Silica sand, glass
GRANITE (commercial name: Taurus)
A natural „granite“ texture with highly durable surface is reached through the combination of attractive natural granites and siliceous sands. Combinations of natural materials in black, grey, white and gold, supplemented with a uniform background in the same or inverse colour shade.
Nature, inorganic components: Granite, silica sand, quartz
MIRRORS (commercial name: Starlight, Brilliant)
High-gloss surface of the product with mirror effects achieved by using mirror granulates or colored glass. The untraditional appearance allows to combine a high-tech image product with other plain components.
Nature, inorganic components: Crushed mirrors, glass, silica sand, quartz
CRYSTAL (commercial name: Crystal, Harmonia, Noble, Noble Pro, Serenity, Trend)
Customer favorite materials in uniform colors, marble design, 3D patterns and a wide range of surface finishes. The Crystal production group offers the most diverse range of TechniStone® products.
Nature, inorganic components: Quartz, silica sand, crushed mirrors, glass, granite
Does the TechniStone® surface used on the kitchen countertop resist mechanical damage?
The TechniStone® product is manufactured from hard minerals and achieves high strength, which predetermines it to a very successful application as kitchen countertops. Usual cutting or beating of meat with a wooden meat beater directly on its surface causes no problems to the product.
Each composite product, no matter how resistant, can of course be damaged by strong, concentrated pressure or by heavy impact, e.g. by strong pressure on the tip of a knife or by a strong hit of a metal mallet. TechniStone® belongs to the most resistant products used for kitchen countertops; nevertheless, it is not completely undamagable.
Does the surface of the TechniStone® product used on the kitchen countertop resist thermal load?
Thanks to the used raw materials TechniStone® is highly resistant to thermal loads occurring in kitchens.
The heat-shock resistance is increased with the increase of the used thickness of TechniStone® ; a slab with the thickness of 30 mm is far more resistant than a 10 mm slab. In spite of this resistance, the TechniStone® surface, like any other composite material, may be damaged by a sudden or lasting exposition to high temperatures (over 120 °C), mainly at the edges and cut-outs of the product, where a crack may appear. Therefore, it is necessary to use insulating pads for putting hot objects aside. These pads must also be placed below every electrical cooking and baking appliances located on the kitchen countertop.
Is the TechniStone® product harmless to health?
The product is certified by the National health institute for health harmlessness, the certificate declares the suitability of using TechniStone® for the production of kitchen countertops.
The product is certified by the NSF International organization with this outcome: the product complies with the Standard 51 NSF/ANSI – Food equipment materials, Solid surfaces for Splash zone.
Are the chromatic and structural particles taking their part at the appearance of the TechniStone® surface intentional?
TechniStone® is mainly built from several chromatic components and granulates of different sizes, which determine its characteristic color structure.
The slight color shade, structure and design deviations due to the fact that the engineered stone TechniStone® is created by more than 90% from natural raw materials where the small color difference is natural characteristic.
Is it necessary to take into account the thermal expansion when using the TechniStone® product as floor and wall tiles?
The polyester resin used as a binder causes not only the increase in the strength characteristics, but also in the thermal expansion of the product, which is higher than the thermal expansion of natural stone or ceramics. Therefore, it is necessary to take this fact into consideration during designing the floors and wall claddings from TechniStone®.
