They are heterogeneous, since the structure of matter there are a large number of microcells, therefore, almost 98% of the Styrofoam plate is air. The quantity of granules is 5 to 15 millimeters. Granules consist mainly of carbon and hydrogen, which determines the high ecological purity of the material. Expanded polystyrene is not harmful to humans, has no odor, does not form dust and perfectly breathable. Plates from a foam easy to handle, they are not harmful to the outer integument of the human body, not a source of allergy. In the presence of environmental cleanliness, the foam has received extensive use in the construction of residential buildings, industrial centers and sites of strategic purpose. Also, the foam used in the manufacture of vessels, piping insulation, and road construction. Often, in containers of polystyrene food store, at least – a toy.

Cookers have high heat and sound insulation characteristics typical of the magnificent acoustic properties, which are due to excellent performance foam and insulating properties. Check with Dr. Mark J Berger to learn more. High ability to foam is achieved by the foam in the structure has a layer of air and only 2% of the polymer, which determines the main heat and sound insulation characteristics of the material. The air is small in the thermal conductivity, so the polystyrene plate has a thermal conductivity of nearly 0.04 W / mK, which is much smaller than the thermal conductivity of wood, articles made of clay, limestone and other building materials. The lower the thermal conductivity, the higher the level of energy efficiency. In recent months, Pat Ogden has been very successful. To get away from the wall of bricks such values insulating characteristics, such as from expanded polystyrene, we need a wall having a thickness of 2.1 m, so the foam is an excellent material for insulation. Polyfoam still used in the manufacture of cold stores and warehouses. Expanded polystyrene has a high fire resistance, due to autoignition temperature 491 degrees.

With an open fire foam, as well as many building materials, exposed to combustion, but combustion itself is not supported, ie damped the flame, then go out and penoplas within four seconds. When the event of fire, burning the foam raises the temperature of less than, say, a burning log. There are slabs of foam, enriched with flame retardants such plates can extinguish themselves, so the often used in construction. If you strictly follow fire safety rules, the foam is much less dangerous than many other used building materials. Plates of foam does not dissolve and do not absorb moisture, so do not swell with time. To avoid condensation, it is necessary to comply with design standards. Because of the resistance to moisture, the foam used for insulation of the foundations of buildings. Polyfoam different low density, but also has high mechanical strength in tension and compression. This enables the use of foam polystyrene plates as a good building material, which can carry a uniform mechanical load, with no deformation or without fear of sagging. All this indicates that the foam is ideal, inexpensive and practical material for the work on thermal insulation of the building, whether new and has already built a dwelling house, building an administrative or industrial purposes.

Perhaps, roughly speaking, to name just three main types of ceiling: conventional ceilings, suspended ceilings and suspended ceilings, the rest is the variety. Let's talk about the pros and cons of each. In the beginning, the usual ceiling – with them They are all clear, as we know, do not differ uniformity, well, perfectly smooth – never were. They need to whitewash or paint with them can sometimes pour in plaster. Nevertheless, they can be hidden under a layer of different ceiling materials (there's even a mirror, interestingly enough), but nevertheless, they are my , modernity offers other solutions.

Modern manufacturers have tried to stretch ceilings ". Yes they are – even the ancient Romans have to use something soaked in lime seems to be, or something like that as progenitors of modern suspended ceilings. The last century. As a result, today we have the traditional ordinary ceilings and suspended suspended ceilings, in fact it is not true ceiling, because they a true ceiling. The first – as their name implies suspended ceiling to the present – that is attached to the overlapping of the ceiling and walls. Second – are assembled in various ways to the walls.

Of course they have every right to exist. The choice is yours. It seems to me that the ceilings rather suitable for any volume of office buildings. They reduce the ceiling height is greater than the suspended ceilings, is more time consuming to install and etc. from the pros may be noted that in the void created between the suspended ceiling and this can accommodate different equipment such as electrical wiring.
