The use of insulation allows you to maintain a comfortable temperature in the house without unnecessary heating costs. When choosing thermal insulation, many factors are taken into account, including its ability to absorb noise. Sound insulation is an important factor in urban housing. Quiet life in the apartment is disturbed by street noise, elevator traffic, neighbors. Rockwool Sound Insulation is a stone wool fiber board designed to effectively absorb sound. The material is environmentally friendly and non-flammable. It will provide peace and quiet in a residential building or office.
The history of the Rockwool trademark
The international company Rockwool was founded in Denmark in 1909. She began to be engaged in the production of thermal insulation since 1937. The brand's products are valued all over the world for their high quality and affordable cost. The main assortment of the company is stone wool products. Plants of the Rockwool trademark were built in 18 countries of the world, including Russia. The manufactured goods are used in the construction of residential buildings and industrial buildings, shipbuilding. Stone wool slabs are used for fire protection, soundproofing and insulation. High production capacity and European quality of goods allowed Rockwool thermal insulation to take a leading position in the building products market.
Advantages and disadvantages of the material
Mineral wool heaters from Rockwool Acoustic Butts series have a fibrous structure that allows you to damp sound waves. When forming the material, the fibers are stacked randomly. A lot of air pockets are formed, which help to absorb sound. Insulation plates are resilient and durable. They fit easily into the frame, do not crumple under load. A significant plus is the environmental friendliness of the material. Basalt wool can be used for interior decoration of residential premises. Rockwool soundproofing is recommended for children's and medical institutions.
The advantages of insulation include:
- Low thermal conductivity - stone wool material does not conduct heat well. This property allows you to provide a comfortable temperature in winter cold and summer heat.
- Effective sound insulation - acoustic plates reduce the level of extraneous sounds to an acceptable level. They protect against airborne and impact noise.
- Fire safety - mineral fibers can withstand high temperatures without igniting and producing smoke. Basalt wool prevents the spread of fire.
- Easy installation - the insulation is sold in the form of lightweight slabs that can be easily laid on the insulated surface. To work with them, no special tools and knowledge are required.
- Water vapor permeability - the fibrous structure of Rockwool Acoustic Baths ensures unhindered water vapor penetration. The room creates a favorable microclimate without excessive humidity.
- Biological resistance - basalt wool is not subject to decay, fungi develop on it. Rodents arrange their homes in insulation.
- Water resistance - the use of special impregnations reduces moisture absorption to a level of 1.5%.
- Rockwool materials for soundproofing walls are offered at affordable prices.
Disadvantages:
- When basalt wool gets wet, its thermal insulation properties are reduced.
- Mineral insulation is allergic to some people.
The number of merit outweighs the disadvantages. In addition, with proper installation, the residents of the house will not notice the disadvantages of thermal insulation.
Specifications
When choosing a heater, it is important to study its performance characteristics:
- Thermal conductivity - 0.035-0.038 W / (m * K).
- Compressibility is less than 12%.
- Water vapor permeability - 0.3 mg / m * h * Pa.
- Fire hazard class - NG, it is absolutely non-combustible insulation.
- Water absorption - 1.5% by volume when immersed in water.
- The maximum operating temperature is 1000 ° C.
- Sound insulation index - 43-59 dB, the indicator depends on the thickness of the layer.
Acoustic Butts slabs parameters:
- length - 1000 mm;
- thickness - 40-200 mm;
- width - 600 mm;
- density - 35-45 kg / m3.
The Acoustic Butts Pro series has a thickness of 27 to 200 mm and is distinguished by an increased density - 60 kg / m3. The manufacturer indicates a service life of 50 years, but the insulation will last longer.
Popular Thickness Rockwool Acoustic
Among the wide range of standard sizes of insulation, 3 types of plates are most popular in construction and repair.
100 mm
Rockwool basalt wool has excellent heat-saving characteristics. It meets all the requirements for acoustic materials. During operation, the plates are not deformed. They are protected from moisture by a hydrophobizing impregnation. Thickness of 100 mm is a popular option due to its wide range of applications. A common way of installing sound insulation is a frame partition with drywall sheets. To reduce the transmission of acoustic vibrations along the metal profile, a sealing tape is laid on it.
50 mm
Material with an average thickness is made from basalt rocks. The chaotic arrangement of the fibers in the acoustic board reduces the noise level by up to 63 dB. Universal insulation is used for frame partitions, ceilings, interfloor ceilings. It has a density of 40 kg / m3. Plates are hydrophobic, they are not afraid of moisture.
27 mm
The slabs with the smallest thickness are called Acoustic Ultrathin. They actively absorb medium and high frequency sounds. The material has increased density, so its efficiency is comparable to thicker slabs. The insulation is safe for health, suitable for children's rooms. Its main advantage is the minimum consumption of free space. Depending on the type of construction made and when using a sealing strip, it reduces extraneous sounds by up to 57 dB.
The use of Rockwool thermal insulation materials
Basalt wool heaters are used for all types of premises. They are compatible with various surfaces: wood, concrete, brick, metal. The product line includes materials for thermal insulation of foundations, plinths, walls, floors and ceilings. Most slabs are versatile and can be used on multiple sites.
Walls
When using Rockwool acoustic boards, walls can be acoustically insulated from inside and outside. Insulation is mounted on external enclosing structures or interior partitions. Before laying, the frame is assembled from metal or wooden guides. The step of the lathing is equal to the width of the material - 60 cm. A moisture-proof and vapor-permeable membrane is attached on top of the sound and heat insulation. Frame partitions with soundproof filling are sheathed with plasterboard sheets. If necessary, the basalt wool is placed in 2 radials with an air gap of 50 mm between them.
Roof
Roof insulation is of particular importance; the Rockwool Scandic line has been developed especially for the pitched structures of private houses. Material with a thickness of 100 and 150 mm is also used for attic rooms.The structure of the slabs is designed for increased loads, they have the ability to restore their original shape. When installing, be sure to use a windproof membrane. Flat roofs of multi-storey buildings are insulated with products from the Ruf Butts series. Dense slabs are used to create soft roofing.
Floor and slabs
For insulation of horizontal structures - floor and interfloor floors - Rockwool Floor Butts insulation is used. Rigid hydrophobic slabs have a density of 100-125 kg / m3. They are designed for high load, contribute to the attenuation of sound propagating from adjacent floors.
Baths and saunas
Premises with high humidity and temperature require sound insulation and insulation with special materials. Sauna Butts plates are produced with one-sided aluminum foil coating. The metallized layer reflects heat and reduces the wetting of the cotton wool. Basalt insulation minimizes the likelihood of fire. It is made from environmentally friendly raw materials, does not grow moldy from moisture.
Technical
Energy conservation is an important aspect of industrial production. Rockwool basalt slabs are used for various tasks of insulation, sound insulation and fire protection of technical objects. They are installed on tanks, pipelines, process equipment and air ducts. For effective sound absorption, the Industrial Batts 80 line was created. The stone wool slabs are 35-100 mm thick. They are recommended for ducts with an air velocity of 20 m / s. The noise reduction index depends on the thickness of the slabs. When using Rockwool materials, sound insulation of air ducts is carried out in a short time and with high efficiency.
Rockwool products are successfully used in private houses and apartments. For insulation and sound insulation, it is used by construction companies and craftsmen who make repairs with their own hands.
