Polystyrene: modern, essential to the success building material. Advantages and disadvantages

polystyrene - is a modern, but relatively recently appeared a material which, however, has gained popularity. First of all, this was made possible through a combination of some pretty important characteristics: high strength, and high levels of heat retention.

Features polystyrene controlled by the state quality standards and other technical documentation.

polystyrene It is a special composite, which is composed of polystyrene and cement. It belongs to the category of especially lightweight concrete. Due to the presence of cement, polystyrene makes the material durable, and polystyrene material provides a low thermal conductivity, and simultaneously gives it lightness. That is, on the amount of cement will depend strength of the product.

Besides polystyrene and cement into the polystyrene may include certain modified additives, which are able to increase the quality of the structure parameters.

pros material

According to state standards, polystyrene has the following physical and mechanical characteristics:

• thermal conductivity;

• vapor permeability;

• resistance to frost;

• Flexural strength;

• average densities;

• shrinkage during curing.

At polystyrene average density should be in the interval 150-600 values ​​in dry form. Density values ​​are precisely define the scope of use of the material. The thermal conductivity should be 0,05-0,145. Of course, the moisture content of products will affect the score, but the ability to keep the temperature will be just as high.

Due to such high thermal insulation characteristics, polystyrene is used as a very active efficient and reliable thermal insulation materialAs well as quality material for construction load-bearing walls a variety of designs.

At small hygroscopicity polystyrene whose value is not more than 8%. This material is subject to shrinkage, which value is typically 1 mm / m2. In general, however, much will depend on the brand, quality of raw materials, as well as the manufacturer.

polystyrene has water vapor permeabilityHe has the ability to establish a favorable and comfortable indoor climate, absorbing excess moisture and saturating its premises at high dry air.

There Polystyrene blocks, equipped paneling, and do not require additional facade decoration. In this case, the liner is fixed without using glue, since a small amount is included in the concrete structure.

polystyrene - it is absolutely new materialWhich makes the construction process easier, more convenient and perfect. This is the best solution, taking into account value for money.

People who have had experience of using polystyrene blocks, argue that this is a very durable, thermal conductivity and frost-resistant material for the construction of buildings of different destination.

cons polystyrene

• shrinks to 3 times greater in comparison with the aerated concrete, foamed concrete.
• the material is not flammable. However, polystyrene is not fireproof. Under the influence of high temperatures in the material are destroyed polystyrene beads.
• need more ventilation as the walls "do not breathe." The humidity can be formed mold.
