Everyone is making every effort to make his home was warm and cozy.At the moment it is quite solvable problem, and this contributes to the use of modern thermal and acoustic insulation materials.Moreover, due to these materials it is possible to reduce the heating costs of the building and to reduce costs for construction materials used in building.
now offer thermal insulation materials on the market quite extensively.We will look at the three most popular among consumers of the form.
Existing insulation materials are divided into:
- made from mineral fibers obtained from glass (glass wool) and basalt stones from the rock (stone wool);
- made of polystyrene.
is expanded polystyrene - white in the form of sintered pellets.Its low cost due to the short production cycle and small power consumption.More
is extruded polystyrene.It is produced in the colored form and has a closed cell structure.Due to the fact that the production of this material is much more expensive, and the cost of the
The advantages of polystyrene include the fact that it is non-hygroscopic, so its thermal insulation properties are not lost when exposed to moisture.In practice, condensate at a virtually will not seriously damage.Moreover, this material is very light and has a sufficiently good strength characteristics.Expanded polystyrene is a polymer, however, it is an environmentally friendly material because it does not contain substances threatening human health.
quite a long time polystyrene foam retains its properties.It is not affected by low temperatures and retains its characteristics at + 90 ° C.Positive qualities of self-extinguishing material trudnovosplamenenie and contribute to the fact that in case of fire, flames along the wall surface is not covered.And besides, in the combustion products do not contain toxic substances.
disadvantages of polystyrene are low water vapor permeability and poor sound insulation.
High temperatures virtually no impact on the mineral wool boards.Its fibers begin to melt only after a two-hour exposure to a temperature not lower than 1000 ° C.Therefore, the main distinguishing feature of materials made from mineral wool is fire resistance.
Despite the fact that the components connecting mineral wool fibers (water-repellent) less heat resistant (250 ° C after being destroyed), this material is still considered to be non-combustible.
Note resistance to a large number of chemicals.Mineral wool insulation is much heavier than Styrofoam.Furthermore, they are still less stable and less rigid.But in spite of this sound insulation properties are much higher, helped by the fibrous structure.
addition, mineral wool is very resistant to temperature changes, and it is easy to operate.
This material can be used for thermal insulation, as the facades and interior finish.Facades insulated rigid and semi-rigid mineral plates, which are more durable.Walling warmed plates and piercing soft mats.
Fiberglass similar to mineral wool both in the method of production and technical parameters.However, the main difference is the raw material.For the production of glass used silica sand and waste glass production.Another distinctive feature is the large length of the fibers in the glass fiber.With this amount of material can be reduced significantly after compression.Therefore, glass can be transported, turning into a tight roll, and then deploying its shape and thickness of the material taken initial shape.
Fiberglass products are also available in the form of rigid plates.Since fiberglass products have a high strength characteristics and can be used for external insulation.
Heaters fiberglass incombustible and safe for human health, resistant to weathering and chemicals.They have a high sound and heat insulation, and are not susceptible to change its properties in the temperature difference.
This durable material can insulate the structure of different forms, without worrying that over time, it deforms and settles.
basic technical characteristics of thermal insulation materials is the thermal conductivity.It depends on such parameters as density, pore arrangement, humidity and temperature of the material.Also, do not be amiss to knowledge of the density, compressive strength, water absorption, fire resistance, vapor permeability and frost.
If predefine values teplovrovodnosti the above materials in the calculation of thermal insulation systems, you will certainly be achieved saving building materials, and in the future for heating buildings minimal power consumption.
