Insulation: types, characteristics, purpose and use

In any temperature mode, insulation does not hurt. If properly implemented, it will become noticeably warmer in the winter in the rooms, and cooler in the summer. allows you to create a comfortable microclimate, as regards not only residential apartments and houses, but also premises for work. Visiting the store, you can make sure that modern manufacturers offer for sale heat insulation in a wide range. It has the form of harnesses, rolls, granules, powders, as well as perlite sand. In addition, heat insulation can be represented by plates, blocks, bricks and cylinders.

If you understand the characteristics, you can choose the option of insulation that is needed. The main property of thermal insulation is its thermal conductivity, it indicates how much heat passes through this material. Today, two types of insulation are known:

  • reflecting;
  • preventing.

The first type allows you to reduce heat consumption, which is ensured by reducing infrared radiation. Preventing insulation is used in most cases and involves the use of insulation with low thermal conductivity. The following materials can be used in this capacity:

  • mixed
  • organic;
  • inorganic.

Organic based heat preventive insulation

types of insulation

Considering the types of insulation, you should pay attention to those that are made on an organic basis. They are widely represented on the modern market, and for their manufacture natural raw materials are used, for example, wastes from the woodworking industry and the agricultural industry. The composition of such insulation includes cement and plastic.

The material is highly resistant to fire, it does not respond to biological effects and does not get wet. It is used where the surface does not heat above 150 ° C. Organic insulation is used as an inner layer in the arrangement of multilayer structures. This should include plastered facades or triple panels.

Characteristics of arbolitovy heater

sprayed insulation

Thermal insulation on an organic basis is precisely the arbolitovy heater, which is a new building material from:

  • shavings;
  • sawdust;
  • chopped straw;
  • reeds.

This insulation for a house has a density of up to 500 kg / m3. Fire resistance at thermal insulation is quite high. The coefficient of thermal conductivity is 0.1 W / (m · K).

The appointment and use of fiberboard

Fiberboard is used for thermal insulation of coatings and walls, and structural - for frame walls, partitions and floors, but only in dry conditions. Today, the main use of fiberboard is expressed in the installation of permanent formwork during construction.

Plates are not removed, according to the principle of some other types of formwork, they perform a constructive function and become part of the wall or floor. With regard to the characteristics of use, the plates are installed in parallel at a certain distance, which will determine the thickness of the wall. After fastening, the grout is filled, most often with concrete.Then the system of the liquid mixture and formwork is left until it hardens.

Ecowool specifications

Ecowool is made from waste paper and cardboard production. If to use for this purpose waste paper, then the material will have not so high quality. It will become dirty faster, moreover, it will be different heterogeneity. Among other important characteristics, sound insulation should be highlighted, which in this case is very high. A layer with a thickness of 1.5 cm will absorb 9 dB of extraneous noise.

The ability to heat insulation is also impressive, but the downside is its reduction during operation. Over time, ecowool loses up to 1/5 of its volume. It absorbs moisture well, this parameter can reach 15% of the volume. When laying by the method of continuous spraying there are no seams, which is an undoubted advantage.

Appointment and use of ecowool

The coating is widely used for sound and heat insulation of various premises, which may have industrial, residential and public use. And you can use the material for thermal insulation of the facade, insulation of walls, roofs and attics.Predominantly, the work is performed by the method of dry blowing, but the material can be applied over the existing insulation.

This roof insulation allows you to get a seamless coating that solves the problem with icicles. The underlay involves the use of a special installation, in the bunker of which the cotton wool is loosened, and then fed through a hose with a nozzle. This method of application allows the material to penetrate into hard-to-reach areas, closing all gaps and gaps.

Cellulose insulation for the roof can be used in the repair work of the facilities in operation and in the construction of new ones. Open blowing is used to isolate horizontal and inclined surfaces, among them should be highlighted:

  • floors;
  • attics;
  • interfloor overlappings;
  • ground floor.

Inorganic heat insulators: mineral wool

Mineral wool may be stone or slag. For the production of the latter, slags formed during casting of nonferrous and ferrous metals are used. Stone wool is based on rocks, and for their binding is used a component based on phenol or urea.The first is most suitable, because mineral wool in this case is less afraid of water than the one that contains urea. Flammability of this material is zero.

It is able to counteract the spread of fire, so it can be used as a means to protect against fire. Chemical passivity is high, but hygroscopicity is low. The material is characterized by excellent sound absorption, therefore, mineral wool is used very often as a sound insulator.
