Mineral wool boards Rockwool "Light Butts" for thermal insulation

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

Rockwool Light Butts is a highly effective product that reliably protects;

• roof;
• external walls;
• attic floors.

In the production of this insulation, the innovative technology "Flexy" is used, in which the edge is made up to 5 cm wide, it stretches along the long side, which allows it to be as springy as possible. The flexed edges are marked with special markers and icons.

Insulation "Scandic Butts" can be called the next most popular. Plates made of this material are lightweight and durable. The components that are used to create such slabs are mineral wool (also called "stone"). It has another name: water repellent. The material has overwhelming advantages over a variety of analogues.

It has excellent thermal conductivity and at the same time does not burn, like, for example, PVC boards. For wooden structures, this fact is an absolute plus.

Another important quality of Scandic Butts is its excellent springiness, which gives additional advantages during transportation and installation. A large selection among such heat plates makes it possible to find the best option for home insulation.

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

Slabs also differ in size. "Scandic" is 1.2 meters long, while "Light" is 1 meter. The longer the length of the insulation, the easier it is to work with it, the number of joints decreases, and also less time is spent on trimming. Thickness is also essential, for Light Butts it ranges from 5 to 20 cm, this parameter is also important when assembling insulation in several layers. Butts is good in structures where there is no heavy load, while Scandic Butts can support a certain weight.

Light Butts Extra is the most technologically advanced material in the Butts family of Rockwool heaters. Insulation makes it possible to "warm" the home with a good margin. It can also be used to treat rooms inside, including partitions and ceilings.

"Extra" has a good density, which eliminates the possibility of sagging on building elements.The strength of such slabs makes it possible to "put" them in frame products up to 6 meters high (for comparison - "Light Butts" can only be placed 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 slabs have unique characteristics.

In this case, the main technical characteristic of the insulation is the thermal conductivity index - 0.035-0.042 W / m · K. Mineral wool fibers are located haphazardly, therefore there are a huge number of microcavities, they create a high thermal insulation effect. Insulation Rockwool is a material made of mineral wool based on basalt fiber. The dimensions of the slabs are related to the characteristics of the material.

Minvata "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 level - KMO;
• sorption humidity is not more than 1%, and water absorption during short-term immersion in 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.

Mineral stone wool "Scandic Butts":

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);
• flammability group NG;
• water absorption during short-term and partial immersion no 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.

Due to its waterproofing and heat-insulating qualities, Scandic Butts is ideal for insulation:

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

Slabs are produced with a large and varied 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 the 1000x600x50 mm format is 6 square meters. Considering that there are ten pieces in the package, it is easy to calculate how much material is required to insulate the area.

"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 XL size has appeared, which is in high demand. For private households, "Light Bats" is more suitable due to its economic feasibility, it has obvious functional advantages.

The price lists of trading platforms indicate prices in which different units of measurement may appear:

• pieces;
• Cubic Meters;
• kits.

Packaging costs from 580 to 890 rubles. Before buying, you should definitely find out how much you need to buy Rockwool Light Butts insulation.

Thermal insulation material of the Rockwool company is the market leader, it has the highest international safety certificate: ECO Material Green.

It is not necessary to have a construction qualification to install Light Butts insulation. Ease of 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 takes place using the frame method. Flexy technology makes it possible to avoid the appearance of gaps. When installing insulation boards, you should use protective equipment:

• gloves;
• glasses;
• closed clothing and footwear.

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

The deformation temperature of the insulation is more than 700 degrees, but the normal temperature at which it is possible to actively 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 condensation from the room. This material does not grow mold or mildew, and is not affected by alkali or acid.

The material should be stored in rooms isolated from moisture, it is desirable to have a positive temperature. It is advisable to store the product on wooden flooring or pallets, while it is forbidden to put them on top of each other. It is highly undesirable to expose the insulation to unnecessary mechanical stress. When calculating the amount of insulation, it is imperative to use the basic parameters:

• the 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 work.

Reviews about the material from Rockwool are mostly positive. Of the shortcomings, the need for protection is noted when working with the material.
