Cork Rolls
Technical cork in rolls
Technical cork rolls (cork backing) is an insulation material made of crushed bark of cork oak, presented in the form of rolls of various thickness (from 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm), with dimensions of 1 m-height, 10 m - length . For a thickness of 10 mm, the length of the roll is 5 m, the height is 1 m.
In our time, this type of cork began to quickly displace the well-known heat-insulating, sound and vibration materials, because its properties are several times higher than that of other insulating materials. A cork with a thickness of 2 and 3 mm (max 4 mm) is used as a substrate for floor coverings. If necessary, you can wrap the subfloor in several layers, its thickness directly depends on the type of subfloor and the chosen floor.
Installation of the technical cork (in rolls):
The great advantage of the cork substrate is its ability to level any unevenness in the substrate. Therefore, along with synthetic types, it is listed in almost every installation manual of the most popular types of flooring.
The cork backing is so flexible that it does not require a high-quality underlay. The basic condition is that the substrate surface is clean, dry and even (no slope).
The cork backing can simply be placed on the base or glued to it. In this case, the choice of installation method depends on the specific situation.
Installation of the cork substrate can be carried out in a room with an air temperature of at least 18 degrees and a humidity of 50-60%.
Laying underlays under various types of floors
The best solution is
cork underlay under parquet, laminate or solid boards. Thanks to its flexibility, it smoothes all unevenness, thus creating a perfectly flat base.
It will not be difficult to install a wooden floor on such a base. Moreover, the cork underlay has excellent shock-absorbing properties, which prevents deformation and premature deterioration of the floor during use. In this case, the optimal thickness of the substrate is 4 mm.
It should be remembered that when laying a cork on a concrete base, it will have to be waterproof. To prevent the cork from becoming saturated with moisture, a polyethylene film is laid under it, the thickness of which must be at least 150 microns.
Under the linoleum, in some cases, a cork underlay is laid, since it is quite difficult to stick the linoleum to the cork. There is a possibility that the linoleum will peel off and deform over time.
You can also put a cork undercoat under the ceramic tiles, and in some cases you cannot do without it. In this situation, the plug will act as a shock absorber, reducing the stresses in the base underneath the lining installed. This also applies to tiles made of artificial or natural stone.
It can be concluded that the cork substrate is quite universal, it can be laid under almost any floor covering. And the simplicity of the floor is another undeniable advantage of this environmentally friendly natural material.
Cork Rolls
Technical cork in rolls is made by processing the bark of the cork oak, which remains after the production of bottle caps, as well as other types of cork linings. In the production process, the bark is crushed to a fine fraction. Then the resulting granules are pressed under pressure, treated with hot steam.
Rolled cork in the form of a continuous ribbon is obtained without the use of additional chemical fillers. Suberin acts as a binder - it is a natural natural glue that is part of the cork, its concentration in the bark is about 45%. Under the influence of steam and high temperature, the individual pellets form one whole under the press, and the coating thickness can be increased by up to 30 percent. Thanks to this technology, all the advantages of cork are preserved:
hypoallergenic and environmentally friendly - the material does not contain chemical inclusions and additives, therefore, during its operation, various harmful substances will not be released in any state: neither during heating / cooling, nor during compression or combustion;
technical cork is a natural antiseptic, mold fungus does not appear on it, it does not rot. In addition, insects do not start in it, rodents do not eat it;
cork coating does not deteriorate under the influence of ultraviolet radiation;
technical cork is very flexible, it easily retains its original shape after bending, twisting or compressing, the rate of permanent deformation is only 0.2% - cork regains its shape even after long-term, high loads. The permanent deformation index after the load has ceased to act after 90 seconds is only 0.35%, after 15 minutes it drops to 0.25%, and after another 2.5 hours, the cork coating almost completely restores its shape and linear dimensions;
rolled cork has excellent thermal insulation properties, the thermal conductivity coefficient is about 0.042 W / (m · deg), according to this indicator, it significantly exceeds ordinary mineral insulation;
technical cork in rolls is not susceptible to temperature, it can be used at both very low and very high (but not higher than 90 ° C) temperatures without losing its properties;
Rolled cork is often used as sound-absorbing material, a layer of only 2 mm allows to reduce the acoustic power by 16 dB, increasing the thickness by 2 times allows to obtain a sound absorption coefficient within 22 dB. Cork is especially good at absorbing the sounds of falling objects;
the technical plug is antistatic and does not accumulate electric charge. In addition, some studies note that it is capable of absorbing, reducing the intensity, various types of radiation (electromagnetic, radioactive).
Cork in a roll is a universal and durable material, separately it is worth paying attention to the fact that its disposal can take place in a natural way.
Roller cork: use cases
Parquet board, laminate, linoleum are in great demand among buyers, including residents of multi-story buildings. These floor coverings can be installed not only very quickly and without significant additional costs, but what is very important - they have a very small thickness, practically without 'eating' the living space. But at the same time, before laying the main coating, you will have to lay a cork substrate, which almost completely eliminates all the disadvantages that concrete floors between apartments have:
leveling the surface - the base (and this is the surface of the reinforced concrete slab) does not differ in evenness. The use of special leveling screeds is a long process (the final hardening of the applied layer takes up to several days), requires preparation and is quite expensive. Cork rollers as a substrate allow you to smooth out any unevenness and level differences. At the same time, thanks to sufficient flexibility and proper selection of thickness, we will obtain an almost perfectly flat working surface for laying the laminate;
the uniformity of the load is a very important factor when laying the lock laminate, during prolonged use, due to uneven load, the joints of the lock will begin to collapse and the floor covering will lose its integrity;
creating a barrier - when laying a floating floor (parquet board, laminate), it is necessary to ensure their protection against contact with the concrete surface and walls, which may cause the coating material to collapse. Important point - many manufacturers of laminate flooring indicate that they should be installed on a subfloor, otherwise the warranty will expire;
acoustic insulation - the concrete slab dampens the noise very poorly. In addition, it is not in vain that laminate flooring is considered the loudest floor covering due to its smooth surface and hard base. Even if you just walk on it, it can cause constant scandals with the neighbors below. Rolled technical cork, laid as a substrate, is able to absorb various noises, providing yew

Cork rolls - best natural isolation
thermal insulation - both from cold (which allows you to save on heating in winter) and from heat (reduce costs due to a working air conditioner). A cork in rolls laid on the floor allows for a very effective thermal insulation layer;
improvement of sanitary and hygienic indicators - a rolled cork laid as a substrate prevents the appearance of mice and insects on it, no mold or fungus starts on it.
The flexible properties of the technical cork cover have a positive effect on the well-being of a person, they allow to reduce the load on the spine and joints.
Rolled technical cork is usually produced in widths of 100 cm and can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm and 10 mm thick. At the same time, if it is necessary to create a thick layer of the substrate - 8-10 mm, it is better to lay two layers on top of each other, fixing them with special cork glue. The thicker the technical plug, the worse it develops, the more likely it is to break.
At the same time, it is very important to choose the right proportion between the floor covering and the thickness of the cork underlay. The rule "the thicker the substrate, the better" does not apply in this case. For example, a layer of cork that is too much will be very springy when you walk on. Over time, this will lead to loosening of the laminate lock and even breakage of the lamellas themselves. In addition, there are certain types of laminates that already have a cork layer on the back. Typically, for 8mm laminate in a domestic environment, it is sufficient to lay a 2mm technical cork backing.
Rolled technical plug can also be used for insulation and sound insulation of walls, especially when finishing large surfaces. But the main problem is that before sticking it to the walls, the technical plug needs to be rolled out and wait a while for it to straighten. In addition, it is easier and more practical to use a sheet of technical cork.
Rolls technical cork: styling features
Before laying, cork rolls must be brought into the room and rolled out - they must straighten, but the most important thing is to adapt to the room and its climatic conditions: temperature and humidity.
Technical plug can be placed on various surfaces: metal, wooden floor and concrete screed. Before starting the installation, you need to carefully prepare the base, clean it of dirt and dust.
In this case, it is important to fulfill two conditions:
the presence of irregularities - the substrate allows you to smooth out small irregularities, they should not exceed 1 mm in height;
humidity - the level of humidity at which it is allowed to lay the technical plug as a substrate, should not exceed 2%. Difficulties may arise with a newly applied concrete screed. Visually, it may appear dry, but the humidity level may be too high to do any finishing work. On average, it is recommended to lay the floor at least a month after pouring the concrete screed. With the use of special mixtures, this period can be significantly reduced. There is a simple way to determine whether the screed is ready for finishing work - an ordinary cellophane film with an area of at least 1 m2 is attached to it. m (in this case it is very important to obtain the tightness of the connection). The film is left for a day, if after this time there is no condensation on the inner surface, you can start laying the technical cork. Otherwise, wait for the screed to dry completely.
When laying a technical plug on a concrete screed, a vapor barrier must first be installed. The simplest option is ordinary construction plastic film. Its strips should be laid with an overlap - about 15 - 20 cm, the edges are fastened with tape. Near the walls, the edges of the foil from the floor surface should protrude to a height of about 2-3 cm. Various foil materials can be an alternative to polyethylene, they are much more expensive, but have a "breathing" effect.
Laying begins with one of the walls, with the individual strips in close contact with each other. The technical cork strips are taped together, but not attached to the ground. A gap of about 1 cm remains between the wall and the strip of cork covering - it must compensate for changes in linear dimensions of the cork under the influence of temperature, humidity and external loads. After that, you can start laying the main layer of the floor.
