Among the materials for the complex warming of the house, mineral wool occupies a leading position. The material has low thermal conductivity, it is safe and easy to install. One of the most popular brands in the construction market is the Russian company Doorhan. Mineral wool Dorhan has international quality certificates. It is manufactured on modern equipment under strict quality control.
What raw materials is Doorhan insulation made of
Mineral wool performance is determined by the raw materials from which it is made. Thermal insulation from rocks is characterized by increased strength, resistance to fire, deformation and moisture. Dorhan insulation, which is made from basalt. Rock melting occurs in an ore-thermal furnace. The product receives a high modulus of acidity 1.8, providing moisture resistance and long-term operation.
During the manufacturing process, hydrophobizing and dedusting substances are added to the fibers. Binding components are used to bond the material. After the formation of the structure of the product undergoes heat treatment.
Advantages and disadvantages
The popularity of mineral wool heaters from basalt rocks is explained by their advantages:
- Plates prevent heat loss, their insulating qualities maintain a favorable temperature in the room.
- Products are made from environmentally friendly raw materials. Due to its low binder content, it is safe for human health.
- Biological stability - mineral fibers are not susceptible to the action of fungus and mold.
- Vapor permeability - basalt wool passes water vapor. The material does not lead to condensation and high humidity.
- Non-combustible insulation increases the fire safety of the building. Basalt fibers do not support combustion, do not emit smoke and toxin components.
- The location of the fibers and the air pores create a high-quality screen that stops the propagation of sound waves.
- Chemical inertness - mineral plates are not afraid of oils and solvents getting on them. In turn, they do not cause corrosion on metal structures.
- Dimensional stability - during operation, the mats do not lose shape, retain their performance.
A significant advantage of the insulation is ease of installation. For laying mats, it is enough to mount the frame. Plates are easily fixed with plastic dowels.
Disadvantages:
- Use as formaldehyde binders.
- Small basalt fibers can cause allergies during work. Material laying is carried out using protective equipment. Residents from possible contact with the insulation are protected by special membranes.
One of the minuses is the cost of basalt thermal insulation. It is more expensive than other types of mineral wool.
