Penoplex 45: material specifications

The walls and foundation of each house must be further warmed so that it can live comfortably inside at any time of the year. The modern construction market does not stand still and every year produces more and more new materials for work. One of them was insulation "Penoplex 45".

This material is a conventional polystyrene, extruded. In this article, we will look at the features and advantages of Penoplex 45, its technical characteristics and scope of application.

The first extrusion apparatus appeared in the United States in the middle of the last century. During the manufacture of the material for polystyrene half-cylinders are high pressure and temperature.The process is accelerated by a special foaming agent consisting of carbon dioxide and light freon. The resulting mixture is more like whipped cream, it is she who passes through the extrusion apparatus, as a result of which the resulting mass becomes finely porous.

Each ball measuring 0.1-0.2 millimeters is isolated from the rest. Their uniform arrangement provides an increased density of the final unit, which has many advantages.

• One of the main advantages is the almost complete moisture resistance of the product. Like all new products, Penoplex 45 was subjected to tests before being put into operation. The creators conducted the following experiment: the blocks were completely immersed in water for a month. Only very little water was absorbed, and then only the first nine days, the subsequent period of the plate no longer absorbed moisture. At the end of the experiment, it turned out that water could penetrate only into the outer walls of the material, while the inner walls remained intact.
• The next advantage of the product is low thermal conductivity., especially in comparison with other heat insulators. Its value is 0.03 W / mK.Due to the previous point, the penoplex blocks can be installed in places with high humidity, while the level of its thermal conductivity remains almost in its place, it can vary between 0.01-0.03 W / mK. That is why materials are recommended for warming roofs, attics and even foundations without installing an additional protective layer.

• Reduced vapor permeability of foam - Another plus of the material, which, along with others, ensures its long service life. Extruded polystyrene foam was repeatedly frozen, and then allowed to thaw, each time its characteristics were measured, which remained unchanged. Thus, the researchers concluded that the foam blocks will last more than fifty years, taking into account all atmospheric changes.
• Uniform arrangement of balls inside the plates and structural uniformity provide increased strength of the material, so Penoplex does not deform even with a large load. Due to its low weight, Penoplex 45 is easy to install, it can be quickly laid along walls, and even newcomers in repair work can do this work.The blocks are easy to cut with an ordinary knife, they do not need a certain level of humidity or temperature, they are mounted even in bad weather. Foam blocks are completely environmentally friendly, their production does not harm the environment, and the freons that are part of, are not subject to fire, do not have a toxic smell and do not destroy the ozone layer.
• Among the advantages of the material indicated and biostability, due to which the appearance of mold or mildew is prevented. It is also inedible for rodents and insects. Foam blocks are not exposed to any chemicals used in the repair or construction works.

However, there are still some types of materials that can adversely affect Penoplex, deform it or even dissolve it. These include the following: formalin, acetone, gasoline or kerosene, any ether blends and polyesters, as well as coal tar and oil paints.

The only drawback of expanded polystyrene is its rapid flammability, which at a certain temperature can damage the plates. Therefore, it is recommended to stack them, focusing on the temperature indicated in the insulation passport.

Penoplex 45 has a fairly affordable price, which, together with good technical data, has enabled him to obtain increased demand in the construction market. The cost of the material is just over 3200 rubles.

Blocks have a fairly wide scope.

• Plates can be used for thermal insulation of basements, foundations of the house, basement, floors and walls in various rooms (residential or public).
• Products warm the streets, sports fields, parking for cars, as well as pedestrian areas.
• Road routes and runways at airports also need thermal insulation, so Penoplex 45 is also used in these cases, since the increased strength and durability of the material guarantee a long service life. In addition to strength, foam blocks give the roads and protection against cracks after severe frosts. If the tracks are built from a special type of soil that does not have moisture resistance, they can swell after rain, snowfall or hail.Insulators will help prevent such a case and prevent the roads from freezing.
• In addition to warming, Penoplex 45 also performs stabilization, vibration damping with frequent dynamic surface loading. Their strength allows them to withstand about fifty tons of weight per 1 m2 and uniformly distribute the force of gravity over the entire base. The presence of such material is very important for greater road safety and security.
• Penoplex 45 in some cases becomes an auxiliary element of the load-bearing walls. In this case, it not only warms, but also strengthens the structure, giving it additional reliability.

The density of products is 35-46 kilograms per 1 m3. Foam blocks absorb 0.4% of water from their volume during the month. The permitted temperature of use of penoplex varies from - 45 to +70 degrees. The plates belong to the fourth category of combustion "G4", which indicates their easy flammability.

The length of all blocks is standard - 240 centimeters, width - 60, but the thickness varies depending on the model, it can be 40, 50, 60, 80 and 100 centimeters. Materials with other dimensions can be made to order. When laying insulation there is no need to be guided by the weather, but it is necessary to protect it from sunlight, as the rays damage the top layer of products.

When laying the segments and semi-cylinders “Penoplex 45”, a special adhesive composition is used. To begin with, it is necessary to thoroughly clean the surface from dust and dirt, prime the cracks and eliminate irregularities. Then glue is applied to the slab, and it is pressed tightly against the wall. In some cases, the insulation is additionally fixed with metal or plastic dowels. The first option is used during work with the external walls of the building, the second - when insulation occurs inside.

Dowels allow you to achieve greater density of installation, but they violate the tightness of sheets. Another reliable fastener that improves the quality of styling of Penoplex is self-tapping screws, which also adversely affect the tightness of products.

When choosing the adhesive composition should be based on the type of finishing works and the type of room. For example, when laying in a room with a high level of humidity it is recommended to buy polyurethane glue. You should also focus on the material of the treated surface. Before you buy, be sure to read the instructions and specifications of the mixture and relate them to the properties of Penoplex, if they are compatible, you can safely take the mixture.

In any hardware store, you can contact a consultant who will give professional advice and help you make the right choice.

Penoplex 45 reviews are mostly positive. Buyers are satisfied with the reliability of the product, its durability, environmental cleanliness, durability and high quality. Allergy sufferers, who were afraid to put their health at risk, left their opinions, but all their fears turned out to be groundless.Foam blocks are absolutely safe for health.
