Foam : insulated house quality!

General information about foam insulation and

Exploring the question of thermal insulation of apartment, it is important to become familiar with certain qualities of materials.Their abundance in the building products market exceeds the norm, it is easy to get lost in the assortment.
Choosing insulation means, pay attention to the product description.Its main task during the winter:

1. Do not let the cold penetrate the wall;
2. Keep the heat available in the rooms;
3. gradually to minimize the use of fuel or electricity.

Based on the above features, considering two categories of insulating materials:

1. used inside the house;
2. used for the exterior walls.

The first option is the elimination of excess external noise, preservation of acoustic insulation.Internal insulation is often "embedded" in the construction of plasterboard.It is appropriate at the beautiful appearance of the home, does not require additional finishing.Sheathing the wall will not be superfluous lining ecowool or foam in the metal profile construction.

specialists note significant shortcomings interior walls:

• lack of quality to protect the walls from the cold;
• insufficient to keep the heat in apartment buildings;
• significant decrease in the area of ​​the room.

second method is appropriate when building a house of shlakoblochnogo materials.Exterior finish is able to ennoble the facade of the building, giving it aesthetic appearance and keep the budget for the completion of the house.
disadvantages of external insulation are considered to be sensitive to the external factors and the need for an additional lining stone.The characteristics of the second embodiment resembles the kind of "coat" of the house.In cold weather, this option is appropriate and is able to retain heat in the building.In hot - need to buy an air conditioner to cool the room and constantly.

polyurethane insulation: foam properties

By definition Wikipedia, the polyurethane foam - a foam.The name corresponds to the group of thermal insulation means, having in its composition of carbonate gaseous particles moving along the inert principle.They differ lightness and ease.In the name of "foam" consumers are obliged to foreign construction companies from Norway, we denote this material.

According qualities worth considering:

• density ranges from 30 to 150. Calculation is made in kilograms per cubic meter.
• ability to conduct heat - from 0.019 to 0.028 W / m.
• Despite the lightness of the structure, characterized by a closed porous foam base.
• use time about 25 years.
• Permissible Exposure degree of material - from minus 150 to plus 150.

foam structure shows - he has a soft quality.Not afraid of bends.Delicate refers to the weight loads.Do not expose the pressure polyurethane foam - it will quickly lose its useful features for thermal insulation, can shrink and lose density.

One of the qualities of foam - the capacity for heat conduction.According to the structural characteristics of the material can pass the cold by 0.2 centimeters.When buying a 0.5 or 1 centimeter walls are sufficiently warmed and reliably protected from frost.The thickness affects the cost directly proportional to the value.Focusing on the climate of the area, you can choose the most appropriate option and budget price.

polyurethane foam has a solid surface.Its pores are closed with a special layer.carbon within the structure of support "vital functions" of foam, ensuring long service life.

Modern heaters can be used for at least half a century.Construction manufacturers have developed a special scheme of purification structures.This is possible with the presence of large amounts of gaseous components.All high-quality production of durable polyurethane monopoly is concentrated in the East - in Japan.

distinguishing characteristic foam necessarily need to call it "indifference" to the temperature changes.He copes with the burning frost and capricious to the heat.It does not have the properties of cooled or heated.A significant drawback is the ability to ignition and good combustion.

presence of inert gases promotes charring carbon.Fire Foam can happen only under the influence of open flame.Experts strongly recommend to check the strength of the material before buying.

Human health effects

Constituent elements of polyurethane foam in many respects may have on human health negative impact.Chemical elements foam destructive effect on the respiratory tract.observed "Volvulus" in certain cases.

strongly recommend not to allow children to this untreated material.Foam
not tolerate acids and alkaline elements.Its use is banned in many factories and enterprises.Upon reaction with detergents not causing oxidation.

Processing walls with polyurethane foam

sale material is in a solid state in the form of plates.It may also apply to liquid.Speaking about the properties of the liquid, it is not necessary to provide the containers with jars.In the DIY stores can be purchased in the intermediate state between liquid and solid.As for the quality it resembles plaster.Apply to be a special spatula.Most of the recommendations to reduce the use of spray devices.

When applying it on the surface of the cinder block, a method of spraying perfectly cope with cracks and cover the entire space.An interesting property of the foam - during solidification, it increases up to 40 percent.Wait for the final drying must be one and a half days.

Comparing polyurethane foam and can call them identical.The expert opinion of professionals indicates a greater number of advantages of the first version:

1. lack of use of adhesive means;
2. coating completely across the surface of the exterior walls;
3. operational processes using a sprayer.

Wall insulation ecowool

Ecowool different from mineral wool increased its eco-friendliness.Its foundation - wood chips.You can not worry about the impact of the material on the health of residents.

main qualities:

1. lack of exposure to combustion.
2. Excellent retains heat and does not miss the cold.
3. has noise insulation properties.
4. length of service.
5. natural material, a beneficial effect on human health.
6. great ability to absorb, to pass air.
7. use at industrial sites.She is not afraid of acid exposure.
8. may reduce the thickness.This is a significant disadvantage in comparison with the foam.
