The process of insulating any building or structure is an obligatory stage of construction and finishing work, which must be taken as responsibly as possible. Correct thermal insulation helps to maintain the optimal temperature in the room, where it will be comfortable enough in winter and summer. For this purpose, it is worth choosing materials from well-known manufacturers, for example, the innovative Rockwool Light Butts insulation, produced by the Rockwool company. It is designed specifically for private buildings and structures, has a high level of reliability and is able to perfectly cope with its functions.
Description of Rockwool Light Butts
Light Butts Scandic is a mineral wool insulation made from gabbro-basalt ore. The rocks are melted at a high temperature and the resulting lava is placed in a centrifuge, which makes it possible to obtain special fibers intended for the formation of insulation of the Scandic series. It is additionally enriched with water-repellent substances in order to exclude water absorption during the thermal insulation process.
At the final stage of production, the building material is transformed into lightweight hydrophobized slabs that look like stone wool. During the production, a special Flexi technology is used, thanks to which the edges of the plates can be pressed. The insulation material is capable of springing, which greatly facilitates installation on structures with a frame made of wood or metal. The flexed edges are marked, a special badge is placed on the end part from the side 1000 mm long and 50 mm wide.
The brand's boards are ideal for creating a heat-insulating layer that does not require special loads. They are used in the formation of partitions, attics, floors between floors, walls of buildings with a small number of floors.
The main advantages of the material
Insulation Rockwool Scandic has an optimal thermal conductivity coefficient equal to 0.039-0.041 W / m-K, which allows it to keep heat indoors in the winter and at the same time keep it cool in hot summer. The use of rocks in the manufacturing process gave the material the ability to withstand the highest temperatures up to +1500 degrees. It is ideal also for structures that are exposed to powerful heating. Rockwool mineral wool slabs are fire resistant and prevent the spread of fire when exposed to direct fire.
The stone wool, from which the slabs are made, has an optimal density and is good for steam, which allows moisture to pass through the material and not linger in it. The brand's material has a high level of environmental friendliness, confirmed by the EcoMaterialGreen certificate, the insulation is not susceptible to mold and various fungi, is not interested in rodents and insects as food. It is resistant to the ingress of alkalis, acids, solvents or oils, which will not damage the fibers of the boards. The list of advantages of the Rockwool Butts Light material includes the following properties:
- increased elasticity and resistance to deformation;
- resistance to fire and moisture;
- the ability to shrink by 60%;
- good thermal insulation;
- no problems during installation and operation, long service life;
- increased environmental friendliness.
Due to its well thought-out composition, the material also provides good sound insulation. This property allows it to be used not only as a heater, but also as an additional soundproofing layer.
Specifications
The thermal conductivity of the material ranges from 0.036 to 0.041 W / m-K, depending on the size of the slabs. The presence of the edges processed using the Flexi technology makes it possible to quickly and easily install the slabs into all types of frames. Rockwool boards are distinguished by their elastic structure, since the fibers in them are located horizontally and vertically. It should be borne in mind that the material should not be subjected to strong pressure, since it is used only for structures with a minimum load. It should also be remembered that with constant heating, the service life of the plates decreases.
The material is not used to protect against excessive noise, its main purpose is to keep warm. But due to the optimal absorption of sounds up to 60 dB, it has additional properties and can be used, among other things, as a means for suppressing noise. This is true for those who use it for the purpose of thermal insulation of floors and frame walls. In general, buyers leave positive reviews about the brand's miniplates, but note their high cost, which is almost the only drawback.
The price of one square meter of a slab with a thickness of 50 mm will be approximately 95 rubles. It is necessary to take into account that the material is laid in several layers, therefore, its quantity in pieces should be calculated in advance.
Application area
Insulation from Rockwool Scandic series is most often used for the purpose of insulating external walls. The best choice is the ventilated facade technology, which ensures perfect steam exchange, which ultimately allows you to prevent the walls from getting wet and choose any decorative coating for the facades. Good technical characteristics of the material make it possible to use it as a heater for two-layer brickwork. Usually builders erect a wall in two layers according to the principle of well masonry, placing the material between the layers.
Plates can also be used in frame construction, laying a layer of insulation between sheet or piece material at the base of a wooden frame. The material is also useful for those who plan to decorate the walls of the house using the "wet facade" technology; it is used for both external and internal wall insulation, if necessary. Insulation Rockwool from the Light Butts Scandic series is suitable not only for walls, but also for floors and ceilings, for example, for the purpose of insulating basements without heating or cold attics.
With its help, floors are effectively insulated on logs or under a screed. The versatility of the material allows it to be used for attics and roof structures, including for the purpose of insulating pitched and flat roofs. Bathrooms and saunas that require special thermal insulation can use slabs in order to maintain optimal heat and prevent excessive moisture in the walls.
Plates in combination with additional materials are suitable for technological equipment and the construction of soundproof structures.
The versatility of Rockwool slabs allows them to be used in any type of construction and successfully insulate walls made of various materials with them. This is the best choice for both professional builders and owners of private buildings.
Installation features
Plates of the brand must be additionally protected from direct exposure to water and condensate; for this purpose, layers of a special membrane are used, which is laid on top of the mineral wool. Most often, a membrane from the same manufacturer is used, for example, Extra. It should be laid with an overlap, gluing the joints between the layers for greater tightness. The slabs must not be left open, otherwise stone particles and fibers may get inside the room. They are additionally closed with a vapor barrier film, siding-type lining, plywood or drywall sheets.
In the process of work, personal protective equipment is always used: glasses, respirators, gloves and overalls.
Most often, the plates are installed as a whole, but sometimes it may be necessary to install fragments, in such cases the material is cut with a knife. During installation, it is recommended not to squeeze the plates over the entire surface; it is better to do this only from one edge, so as not to reduce the effectiveness of the insulation. Each plate is installed on a pre-prepared frame, which greatly simplifies the entire installation process.
For frames, structures made of wooden bars or metal profiles of standard sizes are used. In the process of installing interior partitions, experts recommend making the frame vertical in order to reduce the noise level. If the installation work is carried out in accordance with all the rules, the slabs will reliably protect any room from heat loss, noise and sounds, will help reduce the load on the supporting structures and extend the life of any structure.
Mineral wool is supplemented with hard edges to prevent fibers from falling out. At the same time, all edges are able to fit well with each other, which excludes cold and drafts in finished structures.
