Expanded polystyrene: characteristics, advantages, disadvantages

About sixty years ago, a new building material appeared, called polystyrene foam. Its characteristics far surpassed many heaters known by that time.

The popularity of teaching staff grew exponentially. Today, new excellent insulation materials have been discovered and created, but PPP, better known to us as polystyrene (although polystyrene and polystyrene are produced differently), is still one of the best. Why is polystyrene foam so attractive for builders?

Characteristics of the material and its advantages

The best way to save energy is to warm houses. In order not to "stoke the streets", it is necessary to warm the house well. The easiest way to do this is with an inexpensive, but very reliable PPP. Gas-filled plastic granules conduct heat very poorly. This helps to keep it inside the house in case of any weather changes. Insulation with polystyrene foam can also protect the housing from excess moisture. The faculty is not at all afraid of dampness: even being several days under water, it practically does not get wet. Expanded polystyrene, the characteristics of which can be compared with natural wood, is able to "breathe". Its vapor permeability is approximately the same as that of boards or bricks, so professionals advise to insulate houses from these materials with foam. PPP does not rot at all and does not lend itself to fungus; it muffles the sound perfectly, therefore it can be used not only as a heater, but also as a sound insulator. What is more interesting expanded polystyrene? Its characteristics from the point of view of chemistry are very peculiar.

He is not at all afraid of paints, salts, acids (except for acetic and nitric), so PPP is used almost everywhere in construction. The low cost of the material goes well with its eternity (PPP does not age, does not deform under any conditions). Once you have insulated the house with the help of the teaching staff, you can forget about it forever: you will not have to change the insulation. PPP is available in different forms, but expanded polystyrene tile is especially popular. It can have different sizes (for example, 60x120, 50x100), so builders can choose a format that is convenient to work with. Of course, PPP, like everything else, has a number of disadvantages. However, they are so insignificant that expanded polystyrene remains the most popular among many heaters.

Features and disadvantages

  • PPS is afraid of benzene, dichloroethane and some other solvents.
  • polystyrene tile
    In porous material, rodents sometimes make holes or moves: they also love heat very much. You can scare away animals with the help of chemicals intended for them.
  • The foam itself is flammable. To reduce its fire hazard, manufacturers today add flame retardants to their starting material - substances that prevent burning. Received with their help PPP is marked with a letter.
  • PPP tolerates compression very well, but quite fragile. Modern technologies have helped to solve this problem. Extruded polystyrene foam is much stronger than usual, although it passes vapor somewhat worse. But with a well-functioning ventilation system, this drawback comes to naught.

Do you want to insulate the house inexpensively, but with high quality and for a long time? Choose expanded polystyrene. Do not lose.
