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.
Application area
Wall insulation outside
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 to 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.
Rockwool light batts and Light Butts Scandic are brothers in nature!
To understand how Rockwool Light Butts Scandic differs from Rockwool Light Butts, you need to find out how they are similar? What these two insulation materials have in common is their natural origin. High-tech production makes it possible to use stones in new ways.
Nature itself suggested a solution, when light threads flew out of the volcano from the splashes of the molten mass of rock. Now the "work" of the volcano is performed by the furnaces of the Rockwool factories, and the filaments are laid in light slabs filled with air inside.
The similarities do not end there, and after looking at the technical specifications, it becomes completely unclear why the materials have different names.
Installation features
In the process of installing mineral slabs, experts advise to follow the manufacturer's recommendations so that the service life of the material is as long as possible. Insulation must be laid in at least two layers, overlapping the joints. Thanks to the springy edges, the placement of the slabs is greatly simplified, they do not need to be trimmed or adjusted to size. Already after installation between several rafters or other guiding elements, the material straightens and fills the empty space.It is not difficult to identify the marked side as it is marked with a red stripe.
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.
Membrane Rockwool for roofing
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.
How to use
Insulation Light Butts is used as a thermal insulation layer for vertical and oblique use when insulating coatings of structures, attics, interior partitions, ceilings, walls, an inner layer in air curtain systems of the facade with two-layer insulation. No additional load on the plates is allowed. The increased density led to an increase in the mechanical stability of the material, but an unacceptable load leads to its deformation, and, as a consequence, a deterioration in its thermal insulation properties.
Using mats of different thicknesses, it is easy to achieve the desired layer of insulation. 100 mm slabs are used as the main layer, and 50 mm butts as an additional layer. If, during calculations, it is required to lay the insulation with a layer of 380 mm of insulation, then it is necessary to round it up to a factor of 100 or 50.
The thermal insulation layer, when properly installed, forms a continuous abutment to the frame without the formation of gaps, which avoids heat loss and prevents drafts.
The thickness of insulation for central Russia is 150 mm for external walls, and 200 mm for roof insulation. For northern or southern regions, the thickness of the insulation layer must be increased (decreased) by 50 mm, respectively.
It is possible to reduce the time and costs for the installation of insulation by using a material with a thickness of 100 mm. At the same time, labor costs are reduced, the amount of waste is reduced and the 100 mm plate is better held in the frame. Cut with a construction knife, increasing the size of the material by 20 mm from the size of the opening to be closed.
To calculate the required amount of insulation, it is necessary to take into account:
- the purpose of the building and its geographical location;
- number of storeys of the building and the height of each floor of the house;
- the size of the house in plan;
- the height of the building from “zero” to the ridge;
- the degree of insulation required.
Composition and technology
Light Batts thermal insulation materials are slabs made of basalt wool using the unique Flexy technology. Its feature is the ability of one of the edges of the insulation to spring, decreasing its volume during compression and increasing when the load stops.This makes the material much easier to install on wood and metal frames.
The Rockwool edge, which can change its density, is located on the long side of the slab and is marked for ease of work. During installation, such insulation provides a greater density of adhesion to the structure compared to other materials and does not form gaps, due to which there are no drafts in the room, and heat does not escape outside.
The binder and water-repellent impregnation included in the insulation make it waterproof. Although they leave the possibility of excess water vapor leaving the room without accumulating in the material. And the good thermal insulation properties of the Rockwool slab are due to the chaotic arrangement of the fibers, which reduces their thermal conductivity coefficient.

Rockwool Product Reviews
“My husband decided to do all the work on the roof insulation himself, although there is no experience. On the recommendation of the seller, Rockwool slabs were chosen. It is good that they do not irritate the skin like regular glass wool. And my husband also liked the edge, which can be squeezed a little and the plate lies without cracks. And the price of Light Butts Scandic is the same as that of the TechnoNIKOL stove, although there is no such invention there. We are satisfied with the purchase, we bought it at Leroy Merlin ”.
Vladimir, Moscow region.
“I didn't buy. They all boast about the new, but in fact - all the same, if only to tear off the price higher. What you have seen is almost twice the price of ordinary mineral water! Better to fill up all the cracks with foam, it will be cheaper. "
Yaroslav, Samara.
“For a long time I have been advising my clients to use Rockwool products when insulating a bath. And it does not stick out over time, and everything is thought out to the smallest detail, and it is easy to work with it. In short, if you want quality, I recommend not to skimp on matches! "

Parameters and types of Light Butts
It must be admitted that the popularity of Rockwool heaters would be much less if they did not possess a mass of unique properties and characteristics that distinguish them from the usual materials.
At the same time, the consumer can choose not only standard Light Butts slabs, but also their improved version - Scandic, which differs in properties during installation and transportation.
Types of materials
Rockwool mineral wool is available in 2 versions:
- standard slabs, the dimensions of which are 1.0 × 0.6 m, and the compressibility has a standard value for brand products of 30%, their thickness is in the range of 50-200 mm with a step of 50 mm;
- improved Scandic slabs, having 2 additional standard sizes (0.6 × 0.8 m and 1.2 × 0.6 m) and the ability to compress up to 60%, the thickness of such materials is 100 and 150 mm.
Thus, Scandik insulation is either more convenient than conventional plates for transportation even in passenger cars (small standard size), or, conversely, designed to speed up the installation process (larger version). In addition, the material is produced in vacuum packaging, due to the manufacturing technology of which the shelf life of Rockwool boards increases several times.
