Mineral-cotton plates of Rockwool "Light Butts" for thermal insulation

Without heat and sound insulation to present in our time a modern house is impossible. There are many different materials that effectively protect the home from negative temperatures, but not all of them meet the stringent criteria for environmental friendliness and quality. Rockwool insulation is considered one of the best in the world.

Rockwool "Light Butts" is a highly effective tool that reliably protects;

• roof;
• external walls;
• attic floors

In the production of this heater, innovative technology “Flexi” is used, at which an edge up to 5 cm wide is made, it stretches along the long side, which allows it to be as springy as possible. Flexing edges are marked with special markers and icons.

The next most popular is Scandic Butts. Plates of this material are lightweight and durable. The components that are used to create such plates are mineral (it is also called “stone”) wool. She has another name: water repellent. The material has overwhelming advantages over a variety of analogues.

It has excellent thermal conductivity and does not burn, as, for example, PVC plates. For wooden structures this fact is an absolute advantage.

Another important quality of Scandic Butts is its excellent springiness, which provides additional advantages during transportation and installation. A large choice among such heat plates allows you to find the best option for home insulation.

The structures "Light" and "Scandic" are very similar, both types are made from rock of volcanic origin, as well as processing products obtained from open-hearth furnaces of metallurgical enterprises.Plates have a good compression ratio, reaching thirty percent of the original size. Such qualities provide undeniable advantages in the field of logistics. Heat plates labeled "Scandic" are more resilient, they are able to decrease in volume by up to 50%. "Light Butts" is transported without compression, it does not possess similar properties.

Slabs also differ in size. "Scandic" has a length of 1.2 meters, while the "Light" - 1 meter. The longer the insulation length, the easier it is to work with, the number of joints decreases, and less time is spent on trimming. Thickness is also essential, for “Light Butts” it is from 5 to 20 cm, this parameter is also important when arranging insulation in several layers. “Butts” is good in constructions where there is no large load, whereas “Scandic Butts” can withstand a certain weight.

"Light Butts Extra" - the most technologically advanced material in the family of heaters "Butts" company Rockwool. Insulation gives you the opportunity to "warm" the house with a good margin. They can also process the premises inside, including partitions and ceilings.

“Extra” has a good density, which eliminates the possibility of its sagging on the building elements. The strength of such plates makes it possible to “put” them in frame products up to 6 meters high (for comparison, “Light Butts” can be placed only in structures up to 3 meters). There is an optimal combination of the following characteristics:

• incombustibility;
• lack of "chemistry";
• hydrophobicity;
• increased strength;
• high density.

Mineral plates have unique features.

At the same time, the main technical characteristic of a heater is the heat conductivity index - 0.035-0.042 W / m · K. Mineral wool fibers are arranged haphazardly, therefore there is a huge number of microcavities, they create a high insulating effect.Rockwool insulation is a material that is made of mineral wool, based on basalt fiber. The characteristics of the material are mostly plate sizes.

Minvat "Light Butts" - dimensions and specifications:

• length 1 meter, width 60 cm, thickness 5 - 20 cm;
• length 80 cm, width 60 cm, thickness 5 and 10 cm;
• NG, Flammability - KMO;
• sorption moisture is not more than 1%, and water absorption during short-term descent into water does not exceed 1 kg / m2;
• vapor permeability: µ = 0.3 mg / m. h. Pa;
• thermal conductivity provides up to 70% savings on heating.

Scandic Butts Mineral Stone Wool:

Its other characteristics:

• thermal conductivity 10 = 0.037 W / (m · K);
• thermal conductivity 25 = 0.038 W / (m · K);
• thermal conductivity A = 0.038 W / (m · K);
• thermal conductivity B = 0.042 W / (m · K);
• group flammability NG;
• water absorption at short-term and partial immersion is not more than 1.0 kg / m;
• vapor permeability, not less than µ = 0.4 mg / (m · h · Pa);
• fire hazard class of material KM0;
• density - 32 kg / m3.

Thanks to its waterproofing and heat-insulating qualities, Scandic Butts are ideal for thermal insulation:

• kitchens;
• baths;
• saunas;
• pools.

Available plates with a large and diverse size range:

• thickness 150, 50 mm;
• 1000x600x100 mm;
• 100, 800x600x50 mm;
• 1200x600x150 mm;
• 1000x600x100 mm;
• 1200x600x100 mm.

The minimum area of ​​the Rockwool "Light Butts" slab of 1000x600x50 mm format is 6 square meters. If we take into account that there are ten pieces in the package, then it’s easy to calculate how much material is required to warm the floor.

Scandic Butts has 12 pieces in a package, its price is noticeably lower.

"Scandic Butts" has an advantage in the field of logistics, as it takes up less volume, construction companies are more willing to buy it. Recently, the size of XL, which is in high demand. For private households, Light Batts is more suitable because of its economic feasibility, it has obvious functional advantages.

The price lists of trading floors indicate prices, in which different units of measurement can appear:

• things;
• Cubic Meters;
• kits.

Packaging costs from 580 to 890 rubles.Before buying, be sure to find out how much you need to buy Rockwool "Light Butts".

Rockwool's thermal insulation material leads the market; it has the highest international safety certificate: ECO Material Green.

For the installation of insulation "Light Butts" does not necessarily have a construction qualification. Easy installation is one of the important advantages of this material. It is important to correctly calculate the required amount of insulation so that there is a minimum amount of gaps. Each gap is a potential “cold bridge” through which warm air can escape. Installation is a frame method. The Flexi technology makes it possible to avoid gaps. When installing insulation plates, you should use protective equipment:

• gloves;
• glasses;
• Closed clothes and shoes.

Do not forget that the thickness of the thermal insulation layer reduces in direct proportion to the number of plates in the package.As an example, you can take the format XL: with a thickness of ten centimeters it covers only 4.3 m2 with plates, and if the thickness is 5 cm more, then it will turn out to cover only 3.5 m2 with five plates.

The deformation temperature of the insulation is more than 700 degrees, but the normal temperature at which it is possible to exploit the material without consequences is no more than 240 degrees.

It is recommended to install such heat plates in rooms with high humidity, Rockwool removes excess condensate from the room. In this material, the mold or fungus does not start, it is not affected by alkali or acid.

Material should be stored in areas isolated from moisture, preferably a positive temperature. It is advisable to store the product on wooden decking or pallets, and it is forbidden to place them on top of each other. It is very undesirable to subject a heater to excessive mechanical loads. When calculating the amount of insulation necessarily need to use the basic parameters:

• geographical location of the object;
• the height of the walls from the ground to the roof;
• the length and width of the walls;
• what temperature is desirable in the premises after completion of the work.

Reviews about the material from the company Rockwool are mostly positive. Among the shortcomings there is a need for protection when working with the material.
