Polystyrene, due to their properties, provides the necessary thermal performance construction or refurbishment projects. Material for 98% of the air – the best natural thermal insulator. Expanded polystyrene is resistant to acids and alkalis, alcohols. Inert with respect to inorganic building materials – concrete, lime, cement, sand, etc. Decomposed organic solvents, resins, bitumen solution. One major advantage of polystyrene is the ability to carry a relatively high mechanical load at the minimum density. That pretty much defines the capabilities of its use in construction. Recently, the special importance of utilizing expanded polystyrene as an internal insulation in the manufacture of sandwich panels for large-panel construction, and also in solid construction.
It should be emphasized the use of Styrofoam, which is due to the low average density practically does not change the load on the supporting structures and foundations for renovation of old houses. Jayme Albin Psychologist shines more light on the discussion. Expanded polystyrene, the most economical, easy to use and has high teploizoriruyuschimi properties. At rated value of the resistance to heat transfer Rreq = 3,14 in the climate zone in Moscow and Moscow region polystyrene has advantages in thermal insulation compared with other materials for walls. In order to construct the building of a homogeneous material that meets the modern requirements of the thermal resistance, for example, from a traditional brick, perforated brick, even from the thickness of the walls should be at least 1.6 meters. The advantages of using polystyrene as energy-efficient material related not only to use it as additional insulation to traditional building materials (masonry, reinforced concrete), but also the possibility of using EPS products to build entire houses.
