Types of solid insulation for walls and their characteristics

    With construction and finishing works, an important stage is the insulation of the walls of the room. Solid heat-insulating materials are distinguished by reliability and long service life. They are easy to assemble, due to which this type of insulation has been widespread.

    Advantages

    The use of solid insulation gives a number of advantages. First of all, they do not create problems when installing, which makes it possible to easily carry out work on their own. They are straight stoves, to work with which does not require a doom, frames and other additional designs. As well as these insulators do not need protective wooden, plastic and metal panels, which, of course, saves a significant part of funds.

    Their use allows you to achieve a smooth surface, which is convenient for later shuttering and finishing.

    Solid insulating plates have a solid structure, due to this, they do not give shrinkage and are not deformed, and this plays an important role, given the vertical location of the materials.

    In terms of quality and thermal insulation indicators, they can be compared with ventilated facades with the difference that the price of solid isolation is much lower. Besides, In comparison with soft insulation, they differ much longer service life.

    It should be borne in mind that some solid insulation, such as foam concrete, sandwich panels and others, can be applied as independent designs during the construction of walls and partitions.

    The size of the material is fixed, it is very convenient when calculating their number required for work. Specific specifications are not changed over the period of operation, which once again confirms the durability of these products.

    Varieties of solid insulation there are quite a lot. Each has a set of specific characteristics and properties. However, there are some species, especially those used during construction and finishing works. Among the solid insulation, it is possible to note the penplex, stone cotton wool, polymerbeton, foam glass and others. Consider the most popular varieties in more detail.

    Extruded expanded polystyrene foam

    One of the most common types of insulation. The basis of the material is foamed polystyrene. It also applies in the manufacture of conventional polystyrene and foam. Extruded polystyrene foam is also called penplex. It can be used both with external and internal work.

    This material perfectly transfers temperatures from -50 to +75 degrees. However, it is recommended to avoid excessive heating, under its exposure to the slab may be deformed.

    In this case, extruded polystyrene foam is able to maintain heat indoors in the winter, as well as protect the building from overheating in hot weather. The recommended temperature range is indicated on the label and may differ depending on the brand and density of the product.

    Penoplex has a very low thermal conductivity indicator that does not decrease even when the material is wetting. Due to this, it is an excellent insulation not only for walls, but also for roofs, sex and foundation. Can be used to protect the surface from moisture, has low vapor permeability.

    This thermal insulation material does not react with a significant part of the chemical compounds, but when exposed to some can be deformed and even dissolved. This, for example, gasoline, kerosene, oil paints, acetone, hydrocarbons and others.

    When taking into account their strength, the slabs have high resistance to mechanical loads, when exposed to which the shape and dimensions are preserved.

    The material does not rot, does not decompose, resistant to the occurrence of fungus and mold. However, rodents can cause serious harm to the insulation, as it is quite capable of sprinkting it. In general, manufacturers declare exploitation of fasteners for more than 50 years without loss of characteristics and properties.

    Extruded expanded polystyrene does not create problems when installing. It is fixed on a pre-treated with a soil wall on special glue and dowels. Joints filled with mounting foam. Next, the surface can be prepared under the finish finish. Work can be carried out both independently and with the help of specialists.

    Consumers celebrate a small weight of the material and its low price, which makes the slabs a popular goods in the market.

    Stone Vata

    Stone wool for insulation is presented in the form of solid plates and is widely used in construction. As a solid insulator use basalt cotton wool. It can be used both for external and internal insulation works. It is pretty simple in the installation, attached on the walls without using additional designs. It has a low thermal conductivity and is a non-combustible material.

    Stone wool resistant to fungus, mold and microorganisms, immunity to rodents. It is an environmentally friendly and safe material, has high insulation properties. The stated service life of plates without loss of basic properties – 50 years. Mounted similarly expanded polystyrene.

    Foamglo

    Foam glass is also a solid heat insulator. The production process is foaming of molten glass, and the finished material resembles cells.

    The foam glass is very rigid and durable, it can withstand serious mechanical loads, and also has good thermal conductivity and noise insulation indicators. It has excellent resistance to extreme temperature differences, additional additives allow you to withstand the indicators from -200 to +1000 degrees.

    Material has increased resistance to moisture, bacteria, fungus and mold, while it is environmentally friendly and non-toxic. The installation process does not have features. Plates are attached to glue and fixed with dowels. After that, the surface is plastered, and the finish finish is applied. Manufacturers declare the service life of the foam glass as unlimited.

    Of the disadvantages, quite a large weight can be distinguished in comparison with other heat insulators.
