Styrofoam belongs to the category of building materials and is a foamed plastic with a cellular structure filled with gas. For this reason, it does not absorb heat and does not transmit sounds, which is why it is often used as insulation.
The resourcefulness of the manufacturers has led to the fact that by the method of adding various substances and using different methods of processing, strength and density, resistance to mechanical stress and even color are laid into it at the stage of formation. This determines the popularity of specific types of foamed plastics in the construction and repair of private and multi-storey buildings, technical structures. The site http://www.volbek.ru contains a wide selection of this unique material.
Positive aspects
The technical parameters and physical properties of foam but must be studied in advance, since the material is not intended for operation in certain temperature conditions, and some of its types are far from each other in terms of strength or stability.
- Expanded polystyrene (the real name of foam) is a heat insulator exactly until it gets to the temperature at which it collapses;
- The structure in the form of cells is not conducive to the transmission of sound vibrations, as a result, this material is good also as a sound absorber;
- Types of polystyrene, whose composition does not harm the use in construction, are not toxic. A number of materials are even approved for household use and as food packaging;
- In calm weather, light weight and ease of shape correction become important properties of foam.
Negative moments
It is worth remembering that according to the technical parameters foam is suitable as long as the operating rules are not violated:
- Expanded polystyrene is easily destroyed under the influence of liquids and their vapors such as acetone and benzene, even if they are part of paints;
- The use of p enoplast in the process of building a building does not guarantee that substances and paints based on destructive acetone will not be used later in its vicinity;
- When buying polystyrene, there is not always a guarantee that a particular species is safe during construction and is not toxic to living things;
- Foam blocks are not recommended for use in locked hot rooms, as its cells can be cut even with hot wire.
Foam application
In addition to the fact that foam is used as insulation in buildings, it is also used as a filler for compartments on small ships. Also, floats, bibs and life jackets, medical containers and blocks for
