Features of using Doorhan insulation

Among the materials for complex house insulation, the leading position is occupied by mineral wool. 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. Dorhan mineral wool has international quality certificates. It is produced on modern equipment under strict quality control.

What raw materials is the Doorhan insulation made of?

The performance of mineral wool 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. The rock is melted in an ore-thermal furnace. The product receives a high modulus of acidity of 1.8, which ensures moisture resistance and long-term operation.

During the manufacturing process, water repellents and dedusting agents are added to the fibers. Binding components are used to hold the material together. After the formation of the structure, the products are heat treated.

Advantages and disadvantages

The popularity of mineral wool insulation from basalt rocks is explained by their advantages:

• Plates prevent heat loss, their insulating qualities maintain a favorable room temperature.
• Products are made from environmentally friendly raw materials. Due to the low content of binders, it is safe for human health.
• Biological stability - mineral fibers are not susceptible to the action of fungus and mold.
• Water vapor permeability - basalt wool allows water vapor to pass through. The material does not lead to the formation of 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 air pores create a high-quality screen that stops the propagation of sound waves.
• Chemical inertness - mineral slabs are not afraid to get on them with oils and solvents. In turn, they do not corrode metal structures.
• Dimensional stability - during operation, the mats do not lose their shape, retain their performance characteristics.

A significant advantage of the insulation is the ease of installation. For laying the mats, it is enough to mount the frame. Plates are easily fixed with plastic dowels.

Disadvantages:

• Formaldehyde binders.
• Small basalt fibers can cause allergies during work. The material is laid using protective equipment. Residents from possible contact with the insulation are protected by special membranes.

One of the disadvantages is the cost of basalt insulation. It is more expensive than other types of mineral wool.

The mats are easy to lay and can be easily fixed on vertical and horizontal surfaces. Finished products are packed in shrink wrap.

Product features

During the production process, a special hydrophobizing composition is applied to the basalt fiber, which increases the moisture resistance of the insulation. The water absorption of the material is lower than that of competitive products. The physical and mechanical characteristics of Dorhan thermal insulation make it possible to use it for most structures. Plates have high compressive and tear strength, resist stretching and deformation.

All products of the company undergo a multi-stage quality control. The plant has a laboratory equipped with imported measuring instruments. Linear dimensions of mats, organic matter content, tensile strength are checked. To confirm the quality, buyers of products are provided with international certificates.

Scope of insulation Dorhan

Mineral wool is designed for heat and sound insulation of residential and industrial buildings. A wide assortment allows you to choose a material with optimal characteristics for insulating various parts of the house:

• walls;
• facade systems;
• interfloor and attic floors;
• flat roof;
• the device of the floor along the logs and under the screed;
• production of sandwich panels;
• installation of soundproof interior partitions and acoustic ceilings.

In addition to panel products, the plant produces sandwich panels. In multilayer wall structures, mineral wool is located in the middle. It is an insulating component. Sandwich panels are in demand in the construction of hangars, warehouses, industrial buildings and trade pavilions.

Doorhan thermal insulation range

There are 22 types of mineral plates in the company's catalog. The plant produces insulation for private houses and apartments. The products are distinguished by their density. The technical characteristics determine the scope of its application.

Doorhan Light

Lightweight non-combustible slabs are used in the construction of attics, pitched roofs and floors. They are recommended for the construction of private houses and cottages. Basalt mats are resilient and retain their linear dimensions for a long time. The light weight of the products does not load the structure. The material is offered in a wide range of slab thicknesses - from 50-250 mm. The use of insulation for thermal insulation of walls allows you to maintain a healthy microclimate in the house.

Doorhan Light Extra

Affordable and reliable thermal insulation for non-stressed structures. The material is recommended for private construction. The slabs have the lowest density in the Dorhan product line, at 27 kg / m3. Basalt wool, due to its hydrophobic composition, does not absorb moisture. Smooth edges of the mats ensure a snug fit of the products to each other. The low weight of the boards makes it easy to transport and install.

Doorhan Wagon

Basalt wool Universal is a product for heat and sound insulation of buildings.The average density index allows you to provide optimal performance for building insulation. The material retains its original shape for a long time, does not deform or wrinkle. With standard sizes of plates, their thickness is 50 and 100 mm. Experts advise using Universal mats when maintaining brickwork in a well manner. Insulation made of durable stone fibers is not affected by moisture and biological factors.

Doorhan Acoustic

Insulating the room with mineral wool significantly improves acoustic comfort. Slabs with a density of 60 kg / m3 have a sound absorption coefficient of 0.85.
