Ukryitsya polyfoam from a frost
Expanded polystyrene — ecologically pure, nontoxical warmly - and the sound-proof material applied in building throughout already 40 years and proved as most economic, convenient in application and having the most economic, high degree convenient in application of heat conductivity and paropronitsaemosti.
According to the provided norms to a building thermal protection the wall from expanded polystyrene in 12 sm on the teplosberegayuschim is equivalent in the thickness of all to properties:
To wall from a wooden bar inthe thickness of 0,5 m;
To 2h-metre wall from a brick;
To 4h-metre wall from ferro-concrete.
By expanded polystyrene production gas harmful to atmosphere freon is not used. Expanded polystyrene concerns that group of plastic which at burning allocate precisely same gases, as well as at wood or stopper burning. Modern polyfoams make in fire-resistant performance. The moisture does not influence on teploizoliruyuschie properties of this material and does not cause formation in it of bacteria and a mould that allows to use widely Expanded polystyrene as well in the food-processing industry.
EXPANDED POLYSTYRENE IS APPLIED:
IN DESIGNS OF ROOFS AND WALLS
Whether it be the flat or inclined roof, a wall or an apartment house or establishment floor, but a heat and a cold, dryness and humidity, load snow and a wind outside, humidity of air of premises from within act on them constantly and equally. At isolation of roofs polyfoam is laid depending on a roof design freely or between rafters, pasted or mechanically fastens to the basis. In walls on an outer side of a bearing bricklaying the polyfoam layer is put, and from above — either special plaster, or a ventilated facing cover for are sewn up from an environment. Also polyfoam establish in a hollow bricklaying on special probes. Other system of a thermal protection is application of shaped details from polyfoam for outside walls of buildings. Shaped blocks keep within dry, are laid by metal armature and then filled in with concrete. Recently more and more popular it becomes warm - also a noise isolation of roofs, walls and floors of buildings with use penopolistirolbetona (mixes penoplastovyih balls with liquid concrete).
IN FACING OF FACADES
Penetration rain and thawed snow in internal spaces behind facing does not influence functionality of polyfoams. The system of outside warming and dressing of facades penopolistirolnyimi plates keeps heat and saves a surface of walls in a primordial form during several tens years.
FOR FLOOR ISOLATION
In quality teploizoliruyuschego a material expanded polystyrene is laid in a floor between logs. For achievement of effective isolation from shock noise of a premise are revetted with plates from expanded polystyrene and are covered seamless (for example, cement), or a dry floor which the bottom layer the spring — weight acts as system and can freely fluctuate, preventing thereby penetration of a sound into a floor-ceiling design. Also all is more widely applied penopolistirolbeton.
PROPERTIES
In building expanded polystyrene of two types — plates penopolistirolnyie and ekstrudirovannyiy expanded polystyrene is used.
Expanded polystyrene – ecologically pure material (it is certificated on ecological cleanliness), unlike other construction materials.
Expanded polystyrene is not radioactive, low temperatures do not render influence on its physicotechnical properties, at positive temperatures to 90°S saves formoustoychivost even at long effect.
Thanks to high heat-shielding properties of a material processes of thermal expansion and compression have no essential significance at building and building operation, and absence of cycles of freezing – defrosting excludes occurrence of cracks in bearing designs, therefore they surpass other kinds of protecting designs in durability.
Expanded polystyrene does not contain the substances which are the environment for microorganisms. Experience of its application in the countries of Europe, the USA and others shows, that expanded polystyrene is not a nutrient medium for a mould, bacteria and fungi, and as also rodents (the mouse, a rat).
Expanded polystyrene is inert, therefore is used even at packing of articles of food and as internal cover of modern refrigerators.
For 40 years of application of expanded polystyrene it is noted any case of negative influence of a material on a human body.
Protecting designs with application of various systems of building from expanded polystyrene have factor of heat transfer Ro = 3,56 sq. m To/vt without outside and internal furnish.
Walls from traditional construction materials have Ro the equal:
Wall from a clay brick in the thickness of 64 sm = 0,91
Wall from a silicate brick in the thickness of 64 sm = 0,85
Wall from an effective brick in the thickness of 64 sm = 1,28
Wall from keramzitobetona in the thickness of 40 sm = 0,8
Wall from a tree of 0,3 m = 2,0
Apparently, protecting designs with expanded polystyrene application three times save heat, than walls from traditional materials more effectively.
That the brick wall had the same heat-shielding as protecting designs with expanded polystyrene application, it should have a thickness of 2,5 metres, but thus its weight will be more in 13,5 times!
Working costs to heating of such house are reduced three times since it is not necessary to spend heat large quantity for warming up of walls of the big weight as in case of walls from such materials as a brick, keramzitobeton.
Besides outside protecting designs with application of elements from polystyrene have low specific weight – 1 sq.m. of a wall weighs 270 – 300 kg, that gives the chance to avoid expenses for strengthening of the bases at reconstruction and superstructures (2 floors) existing buildings and as considerably to lower expenses on erection of the bases of again under construction buildings.
In building expanded polystyrene of two types — plates penopolistirolnyie and ekstrudirovannyiy expanded polystyrene is used.
