Although natural stone has been used as floor material for a long time, this material is not so common here Nordic region. The most likely reason is our cool climate. A floor in natural stone can feel cold and unpleasant. On good grounds, however, it can be expected that stone floors will be much more common in the future. This development relates, in particular, to the modern technology that makes efficient floor heating possible. With its rich variety of color, texture and finishing, the natural stone is remarkably adaptable as floor coverings. But the benefits do not only have the appearance to do. The durability is also much better than many other flooring materials.
Although materials and installation costs may be higher than other materials, this investment will be compensated for the considerably long life expectancy. It is not uncommon that the annual cost of a stone floor in the long run will be lower than for most other flooring materials. There are examples of marble floors in department stores that are in good condition after 60 years of daily wear, despite using marble with normal abrasion values. Another advantage of natural stone is that single tiles exposed to extreme puncture wear or otherwise damaged are easy to change without the rest of the floor requiring a refurbishment or treatment.
The previously mentioned combination of underfloor heating makes the floor of natural stone especially interesting. All natural stones have high heat capacity, which gives two very big advantages in housing. The floors are comfortable walking and water dries up quickly.
A more lightweight laying technique also speaks for stone floors. Traditionally, you will usually lay rock in cement mills, but later technology implies that thin, even-thickness stones are laid in fasteners against flat surfaces. This makes it possible to use natural stone even in so-called single-beam joints, where the concrete concrete has a flat surface.
The material thus becomes useful even in villas, where it is often difficult to adapt the substrate to traditional setting. In homes, flooring of natural stone has hitherto been mostly used in entrances and halls. The technique of fastening material also opens up possibilities for laying in other areas.
The natural stone wall for indoor floors is surprisingly large. Both domestic and foreign stones occur. Most products are import goods. Many are similar to each other.
Among the imported goods, many go under the name of marble without being genuine marble. Among other things, there are several polished limestone species in the same shape as just marble.
In the wide range you can clearly distinguish five standard stones: marble, limestone, slate, hard sandstone and granite. The price of natural stone is very varied. There are floor tiles for a few dogs ralppers per square meter, but also those that cost several thousand in the same size.
A common view is that slippery floors in natural stone are slippery. With its mirroring surface, a polished floor also gives the impression of being lame. However, most surveys show the opposite.
If you want a stiffer surface, you can, for example, choose quartz sandstone or gloss shale. Even a coarser ground, planed or flammable surface gives a stiffer surface.
The surface treatment is of great importance to the floor's appearance. While a polished and fine-grained surface emphasizes the color and texture of the material, coarser finishes, such as planing, make the color lighter and the texture less clear. However, it is not uncommon for even coarser surfaces to get a more saturated color over time.
Smoother, undiluted surfaces can be harder to keep clean, especially if cleaned by hand. However, if you have the option of using a scrubber, cleaning is trouble-free.
The color selection may have some significance for cleaning. Dirt and footprint, for example, appear more clearly on single-colored dark or bright surfaces than on stone surfaces with varying color and texture.
Certain stone varieties are dull over time and may even be stiff and somewhat dull. However, these changes are almost always accompanied by so much wear and tear that they do not cause any problems in normal homes.
Floor tiles are available in varying formats, including square and rectangular tiles, which provide great opportunity for pattern layout, The disc and plate thicknesses often vary between 20-30 mm, but the plates can also be even thicknesses, 10 or 20 mm with a tolerance of 1 mm. The thickness of one and the same lot may vary within these limits.
In descending lenght, the following widths are usually in stock: marble and limestone - 100, 150, 200 and 300 mm; slate 150, 200, 250, 300, 350 and 400 mm. In addition, layered even-thickness 10 mm plates of many 200 × 400 mm marble, limestone and granite varieties, sometimes 150 × 300 mm in size.
One way to get a floor in natural stone is to buy older stones that have preserved from a demolition. It is becoming more common to use old stones. Smaller companies or individuals often stand for this trade.
