Polystyrene foam plates

. Actively used in construction and life, sheets of polyfoam already for many years continue to remain one of the most popular, at the same time, ecologically safe synthetic construction materials. Polyfoam is rather simple in application and is economic, and in addition possesses excellent warm and sound-proof indicators. On the Internet and newspapers it is possible to see rather often announcements in style "to this day I will buy polyfoam" that once again proves its high value and a demand - including in the construction market.
Being synthetic material, polyfoam, nevertheless, is chemically neutral and safe for the person. It does not emit harmful substances, does not decay under the influence of microorganisms that is important, has practically no expiration date. Even when burning from it the substances similar to that which are released when burning a stopper or wood are emitted. And modern Knauf Therm polyfoam at all practically negoryuch - the substances interfering ignition are added to its structure. This material is also unreceptive to moisture, on its surface bacteria and a mold do not get divorced - it does it irreplaceable, including, in the food industry. Thanks to very low prices of material, is able to afford to buy polyfoam practically everyone.
Polyfoam sheet, in addition, possesses excellent resistance to asphalt emulsions, and also roofing material components. Also other chemicals - fertilizers, paints, alkaline and hydrochloric solutions, and also lime and plaster are safe for its structure. A bigger firmness characterizes firm sheets of polyfoam - the pressed option of standard expanded polystyrene. Perhaps, the only natural factor significantly influencing its structure is ultra-violet light - under its influence polyfoam becomes more fragile and subject to destruction. As for chemical compounds, pernicious impact on expanded polystyrene is made by organic solvents, alcohols, oil products.
Warming by polyfoam is one of the easiest and cheap ways to create rather comfortable dwelling. On heat-insulating polyfoam the price is several times lower, than on popular foamy blocks and also mineral wool, however its efficiency can envy. So, on the heatpreserving properties the same effect, as a wall from a wooden bar thickness in half-meter, a bricklaying two meters thick and a reinforced concrete wall four meters thick has the sheet of expanded polystyrene. And set of the above described qualities does warming of walls by polyfoam much more favorable in every respect.
 Being actively applied in construction - as, for example, ceiling polyfoam, - expanded polystyrene even more often comes to the rescue of workers of the advertizing sphere.
