The latest developments in modern construction allow you to achieve the best results and get a versatile material that can protect against adverse external environmental influences. One of these is stone bas alt wool. More on this later.
General description of the item listed
This is pretty popular stuff. It is obtained by pressing stone bas alt rocks and hydrophobic binders. This process is not that complicated. Stone, or bas alt, wool is a durable, fire-resistant, wear-resistant material. It is used in the construction of residential and public buildings, as well as kindergartens. The material has the highest performance characteristics and is carried out according to the quality standard according to GOST.
Technical description
Stone wool is a type of mineral wool. The main advantage of this insulation is that it is environmentally friendly.material, as it is made from molten rocks of gabbro-bas alt. Even in ancient times, local residents noticed the fact of a volcanic eruption, in the remains of which strong and long fibers were found. Based on this, bas alt wool was later invented. This is the correct data.
The components that make up this insulation (stone wool) are various binders. They hold fibers together. These include synthetic, bituminous, composite binders (carbamide resins and bentonite clay). These components give the product the desired density and shape.
Properties and characteristics of stone wool
There are many interesting things in this plan. Namely:
- The main and main property is the incombustibility of the material. The degree of this parameter provides a barrier that can withstand quite significant temperatures - up to 1000 ° C. This is an absolute class of fire safety. Therefore, in difficult situations, stone wool will create a barrier that can protect the structure from further fire penetration.
- The thermal conductivity of the material is quite small. Its value lies in the range from 0.032 to 0.048 watts per meter. This allows the material to keep warm in cold weather and keep the room cool in summer. This is achieved by a chaotic arrangement of fibers in a bas alt insulation.
- Strength characteristicsmaterials help it resist deformation under compression and tension. Stone mineral wool is able to withstand huge loads. Experience and studies have shown the compressive strength of the material - from 5 to 80 kPa. Thus, it is proved that the material will last for many years without changing its size and shape.
- The acoustic properties of the insulation allow it to absorb noise, reduce the reverberation time. This helps to protect not only the walls of one isolated room from sound waves, but also neighboring rooms.
- Shrinkage of stone wool is minimal (about 5%). This also guarantees the durability of the material and prevents the formation of cold bridges in the niches of the frame.
- The water-repellent composition of stone wool (with the addition of blend or limestone) has a hydrophobic property. Therefore, this insulation is great for rooms with high humidity (baths or saunas). Water absorption in this case is about 2%
- Stone wool has absolute vapor permeability. The ingress of moisture on the surface of the insulation does not form condensate, because it does not get wet and retains heat. Air is removed from damp rooms without any obstacles. The vapor permeability of this material is about 0.3 mg.
- The resistance of stone wool to aggressive environments, as experience shows, is significant. It is not subject to rotting, mold or fungus damage, and is also not afraid of it.small rodents, because it is a fairly solid material. In contact with metal, stone wool does not leave traces of rust. Therefore, the specified insulation is used in industrial and technical facilities in contact with aggressive environments.
- Sustainability. The specified cotton wool is made from natural mineral raw materials. This is important. During production, bas alt fiber is combined with formaldehyde resin, which makes the material dense. However, harmful resin impurities are neutralized during the production process. Stone bas alt wool does not cause allergies. Its fibers do not irritate the skin.
- The density of stone wool is quite high (from 30 to 100 kg/m³). This property allows the material to maintain rigidity and resistance to deformation.
This insulation is easy to transport. This material is produced mainly in slabs. The product is delivered to the construction site packed in polyethylene. This makes it easier to store as well
Application
Stone wool is a fairly versatile insulation, and its use is possible in various areas of construction. This material is used in the following cases:
- In hinged ventilated facades.
- For insulation of external and internal walls of the building.
- In extensions to buildings, balconies and loggias.
- For insulation of roofs, pipelines, ceilings.
- In walls made of various materials: brick, concrete, stone, wood, metal.
- For warmingfloors and ceilings.
- For insulation of fire hazardous objects, furnaces, pipelines.
Installation of stone wool
This process is quite simple. There are soft, rigid and semi-rigid stone wool slabs. This simplifies the installation of the specified material - no special skills, specialists are required, as well as the use of complex tools or equipment. Stone wool can be glued with special construction adhesive or attached with dowels. After that, a layer of vapor barrier is laid, then you can proceed to the finish.
Tip
When working with this material, it is best to use a cotton-gauze bandage or respiratory mask to prevent dust from entering the respiratory tract.
Main criteria for purchasing this material
Do not forget that when buying this product, you should carefully review the quality certificate and check that the formaldehyde content is minimal. Well-known manufacturers of bas alt wool strive to ensure that the presence of harmful impurities in this material is at the lowest level. Therefore, it is better to buy the specified insulation from companies that have already proven themselves in the construction market.
Conclusions
Bas alt, or stone, wool is a product obtained by melting rocks with the addition of binder mixtures. This heater is environmentally friendlypure material, safe for human he alth and the environment. However, it contains formaldehyde and phenol. During the melt process, these additives evaporate from the total composition of the insulation. Stone wool, which has positive reviews, is an excellent material and is popular in the construction and renovation industry.
