Thermal insulation of a house or any structure is a very important stage. Laying specialized materials will allow you to achieve the desired temperature level in the room, save thermal energy and ensure comfortable living. Moreover, the easier the material used is to work with and the more reliable and durable it is, the better from the point of view of construction and operation of the premises. Penoplex Comfort, technical characteristics, features and a description of the installation process of which can be found in this material, is one of the most popular newest thermal insulation coatings on the construction market.
This is a fairly new material, which is made using the extrusion method from polystyrene and helps to solve a number of problems at once:
- allows you to achieve a high level of thermal insulation;
- protects all building structures from exposure to cold;
- helps reduce heating costs;
- provides a healthy and suitable indoor microclimate for humans.
The material has many advantages over conventional insulation materials, which is why it has earned popularity. First of all, it is worth noting its homogeneous porous structure, as well as its low weight, which makes it easy to work with the material and not burden the structure. Thanks to its homogeneity, the material does not crumble.
is a large Russian manufacturer of construction and decorative finishing materials based on polymers. The company began its activities in 1998 with the launch of the first production line in Russia for the production of thermal insulation materials from extruded polystyrene foam under the PENOPLEX® brand.
produces extruded polystyrene foam (EPS or XPS). This material is used as insulation. It differs from its cheaper analogue - foamed polystyrene (foam plastic, EPS or PPS) in its greater density, due to which it better withstands mechanical loads. Another distinctive feature is lower vapor permeability. Or rather, it produces almost no steam. And the main trump card is the best thermal characteristics. Penoplex 20 mm thick in terms of heat retention is equivalent to almost double the thickness of mineral wool and 37 cm of brickwork.
Penoplex is a modern, effective thermal insulation material.
These characteristics determine the area of use of Penoplex. It is recommended for insulating areas where resistance to stress is important, and low vapor permeability is one of the requirements. More specifically, it is recommended to use Penoplex:
- For floor insulation: under the screed, on it, as an intermediate layer;
- when installing a floor on joists (with some reservations);
- thermal insulation layer under a heated floor (water or electric).
Another area of use is thermal insulation of facades or interior walls. But here you need to understand that due to the fact that Penoplex practically does not conduct moisture, additional measures will be needed to ensure that vapors do not get inside the wall. In addition, a well-thought-out ventilation system is needed to normalize the humidity in the house. And, in addition, you need to select the thickness of the insulation so that the dew point is inside the insulation, but not in the wall.
Optimally - insulation of a recessed base
If you prefer “breathable” walls and natural humidity regulation, Penoplex is not suitable for wall insulation in this case. It does not fit under ventilated facades either. The exact task there is to remove moisture from the insulation due to the movement of air in the ventilation gap. This material is not able to provide this, since moisture simply does not get inside Penoplex.
One of the best insulation
Penoplex is the most popular thermal insulation material.
Despite the presence of disadvantages, penoplex is the most popular thermal insulation material. It is stronger than polystyrene foam and is absolutely safe for installation. The abundance of extruded polystyrene foam boards on the market allows you to select the required size and thickness, depending on the purpose of use.
Appearance, description
Insulation made of polystyrene, pressed into plates - EPS. The PENOPLEX company was one of the first in Russia to start producing this heat-insulating material. In appearance, extruded polystyrene foam is similar to regular foam, but its structure is denser, the cells are smaller, and the color is orange.
Production technology
To understand what penoplex is, consideration of the method of manufacturing insulation will help, since it is the special technology that gives it the necessary performance qualities.
Unlike the production of pressless polystyrene foam (PSB), penoplex is subjected to pressure and molding. The manufacturing technology is as follows:
- Polystyrene granules are mixed and exposed to high temperature.
- A foaming agent (consisting of freon and carbon dioxide) is added to the fused mixture under pressure, which is responsible for creating small cells.
- The resulting mixture is passed through an extruder for molding.
- The resulting sheets are cooled.
- Cutting into slabs of the required size is carried out.
The finished slabs are wrapped in a special shrink film, which minimizes the negative impact of external factors without blocking visibility for consumers. Through it it is easy to determine what it is and how much the integrity of the material has been preserved.
Types, sizes and weights of thermal insulation boards
The characteristics of insulation depend on its parameters. The slabs are available in various thicknesses and lengths.
When ordering, you can specify your sizes. The manufacturer is able to implement even non-standardized parameters. The main indicators vary within the following limits:
- thickness: 2-10 cm;
- length: 1.2-2.4 m;
- width – 60 cm.
Since the cost of penoplex is considerable, it is better to choose the right thickness and determine in advance the required amount of insulation in order to eliminate excessive costs for thermal insulation of the house.
Strength
High-quality XPS insulation boasts excellent strength even at an average weight value. This characteristic is important during the installation process. Durable slabs are easy and convenient to cut and attach to the structure. This material does not create problems during transportation and storage. High strength allows you to maintain the shape of the slabs for a long time, without fear that the material will turn into dust.
If during the installation process you notice the formation of cracks, chips, deformation, and also hear a cracking sound, it means that you purchased a low-quality product. Be as careful as possible when laying it so as not to damage the slabs.
Calculation of material quantity
The packaging of penoplex usually indicates the area and volume of insulation, which means that the required amount can be calculated in two ways:
- Calculate the area of the insulated surface. Find out the area of insulation in the package. For example, to insulate 20 m² with extruded polystyrene foam 40 mm thick, 3.2 packages will be required (since the insulation area in the package is 6.24 m², the calculation is as follows: 20/6.24 = 3.2).
- According to the volume of required insulation. To determine the volume of the surface to be thermally insulated, you will need to multiply its area by the thickness of the penoplex. In the case of 20 m², the volume of the insulated surface is 0.8 m³ (20 m * 0.04 m). The volume of one package of penoplex with a thickness of 40 mm is 0.2493 m³. Therefore, for thermal insulation you will need 3.2 packages (0.8/0.2493=3.2).
If during calculations it turns out that a non-integer number of packages is required, then it is better to find a supplier from whom you can purchase the material in separate sheets. This will save money, but you will have to correctly calculate the missing number of slabs.
When purchasing extruded polystyrene foam, it is better to take a small supply of 12 sheets, since unforeseen situations and improper trimming can lead to damage to the material.
Form
By assessing the shape, you can also say a lot about the quality and effectiveness of the material. The most practical XPS boards have an L-shaped edge. Due to it, installation is faster and easier. Each individual sheet is mounted with an overlap, eliminating the possibility of the formation of cold bridges.
When using slabs with standard, evenly shaped ends, foaming will be necessary. This is an additional repair process that requires not only time, but also financial investment.
Types and what are their differences
Penoplex is a universal material that is used for thermal insulation of various structures. Manufacturers produce several product lines to make it easier for consumers to choose the right material.
Wall
Penoplex Wall is designed for thermal insulation of internal and external structures. Insulating exterior walls is more effective and helps reduce heating costs. This type is also suitable for thermal insulation of partitions and facade systems. A distinctive feature of the slabs is the presence of stripes on the surface, applied with a milling cutter. The rough surface improves the adhesive properties of the insulation, resulting in strong adhesion to the base.
Foundation
Foundations, floors, house paths, and plinths are insulated with Penoplex Foundation material. Its distinctive feature is its high strength, which allows the use of insulation for floors and other structures where there are requirements to withstand significant loads. The slabs have a low moisture absorption coefficient, which is useful because this quality allows you to reliably protect the basement and foundation of the house.
Roof
Extruded polystyrene foam for thermal insulation of flat and pitched roofs has high heat-saving qualities. Recently, the manufacturer has been producing a universal version of Penoplex Roofing and a specialized Penoplex Pitched Roofing, characterized by a longer length and a special tongue-and-groove fastening system.
Slope
Special elements for creating slope and counter-slope structures on roofs, parapets and other protruding structures are presented in the Penoplex Slope line. These extruded polystyrene foam elements have different widths on two sides and provide the required angle.
Block
Penoplex Block consists of several glued polystyrene foam boards.
The increased thickness allows the material to withstand high loads, which is why it is used in road construction.
Comfort
Penoplex Comfort is in demand among consumers. For mansions (balconies, loggias, extensions) and city apartments, this is the most common option, which has important heat-saving characteristics, high reliability, strength and durability. At the same time, the cost of this line is in the average price range. Has an L-shaped edge to prevent the formation of cold bridges.
GEO
Penoplex GEO is an alternative to extruded polystyrene foam for foundations, floors, blind areas and other structures that are subject to heavy loads. Unlike the Foundation line, GEO has greater compressive strength and is more often used in professional construction.
The basis
Penoplex Base has sufficient compressive strength and is considered a universal heat insulator, as it can be used for walls, floors, roofs, provided there are no heavy loads. In all respects, this line is close to Penoplex Comfort, but the Base is more often used in professional construction, and Comfort in domestic construction.
Facade
An improved option for walls, which can be used for insulation outside, inside, and also be part of facade systems. Penoplex Facade has characteristics similar to the Wall line. It has an L-shaped edge, which guarantees the absence of through seams.
Reflective type thermal insulation
Insulation materials, called reflective or reflective, work on the principle of slowing down the movement of heat. After all, every building material is capable of absorbing this heat and then radiating it. As is known, heat loss occurs mainly due to the exit of infrared rays from the building. They easily penetrate even materials with low thermal conductivity.
But there are other substances - their surface is capable of reflecting from 97 to 99 percent of the heat reaching it. These are, for example, silver, gold and polished aluminum without impurities. By taking one of these materials and constructing a thermal barrier using polyethylene film, you can get an excellent thermal insulator. Moreover, it will also serve as a vapor barrier. Therefore, it is ideal for insulating a bathhouse or sauna.
Today's reflective insulation is polished aluminum (one or two layers) plus polyethylene foam (one layer). This material is thin, but gives a tangible result. So, with a thickness of such insulation from 1 to 2.5 centimeters, the effect will be the same as when using a fibrous heat insulator from 10 to 27 centimeters thick. As an example, let's name Armofol, Ecofol, Porilex, Penofol.
One of the types of reflective thermal insulation.
So, we have listed all types of insulation and their characteristics. When choosing one of them, pay attention to the possibility of its complex use. It’s not bad if this material not only insulates your home, but also protects it from noise and gusts of wind.
Details about the characteristics
Extruded polystyrene foam has gained popularity due to its excellent performance and quality characteristics.
Extruded polystyrene foam has gained popularity due to its excellent performance and quality characteristics. In many respects, the insulation is superior to all known thermal insulation materials.
Coefficient of thermal conductivity
Low thermal conductivity allows for effective insulation. The coefficient is almost 10 times lower than that of high-quality mineral wool. Penoplex has a thermal conductivity coefficient at 25±5°C of 0.032 W/(m•°K).
Low vapor permeability
The vapor permeability of the material is almost zero.
This allows for better thermal insulation, but can lead to condensation, so it is not recommended to use penoplex when insulating baths and saunas.
Moisture resistance
The material has a high moisture resistance, which allows such insulation to be carried out without additional waterproofing. Moisture absorption is practically zero.
Features of foamed heat insulators
The thermal conductivity of a particular insulation largely depends on the amount of atmospheric or other gas (for example, carbon dioxide) that is in the pores of the material. Typically, air is contained in sealed cells of a porous thermal insulator (foam) or between individual strands of fibrous material (basalt wool).
There are many types of foam insulation.
Foamed insulation is a separate category of insulation materials, which, as the name suggests, are obtained by foaming raw materials (mineral or polymer) with the participation of third-party chemicals (foaming agents) or using other technology (for example, using steam).
Due to the specifics of production, foam materials acquire not only a low thermal conductivity coefficient, but also a whole set of additional advantages, which I want to talk about below.
Long service life
The manufacturer claims a minimum service life of 50 years. However, there is no exact data available, since extruded polystyrene foam has been produced for insulation only since 1998.
Compressive strength
The compressive strength of extruded polystyrene foam is high. The indicator varies depending on the line of material. On average, the compressive strength of penoplex is 0.25-0.5 MPa. The higher the number, the greater the load the insulation will withstand.
Environmental friendliness
Despite the fact that the insulation is made from polymers, it does not harm the environment because it does not react with aggressive substances. Only when burning can harmful smoke be released, which can harm a person. Otherwise, penoplex does not harm a person. use during insulation does not require the use of personal protective equipment.
Fireproof properties
According to the flammability class, the material belongs to highly and moderately flammable (G3-G4). In this case, penoplex burns only when exposed to direct fire. In other situations, it smolders and is not able to sustain combustion on its own. Manufacturers strive to reduce the flammability of insulation by adding fire retardants.
Structure
Extruded polystyrene foam, manufactured according to all the rules, must have a uniform structure. Be sure to evaluate this when purchasing finishing materials. There should be no voids, recesses, seals or other defects on the canvas. Flaws indicate low quality products.
The optimal cell size varies from 0.05 to 0.08 mm. This difference is invisible to the naked eye. Low-grade XPS insulation has enlarged cells ranging from 1 to 2 mm. The microporous structure is essential for the effectiveness of the material. It is the key to minimal water absorption and high efficiency.
Scope of application
Performance characteristics allow the use of polystyrene foam in various situations, both in domestic and industrial construction.
Insulation of façade walls from the outside
External wall insulation is considered the most effective. To do this, use the material of the Base or Wall ruler. Thermal insulation of external walls allows you to significantly save on heating costs in winter.
Insulation of the walls of a balcony or loggia
High heat-saving characteristics make it possible not only to insulate a balcony or loggia using penoplex, but also to make it an extension of the apartment, increasing the usable area of the room.
Roof thermal insulation
The roof is insulated using extruded polystyrene foam both from the inside and outside. At the same time, it is possible to combine various materials for external and internal thermal insulation to achieve a better result. Penoplex is ideal for both flat and pitched roofs.
Thermal insulation of concrete floor
Strength indicators allow the material to be used for floor insulation on concrete screed. This is also facilitated by low moisture and vapor permeability.
Reviews
Let's summarize the article with opinions about XPS insulation. The Internet has collected many reviews about the product, both laudatory and negative. It is safe to say that the majority of reviews are positive. Buyers note such qualities as environmental friendliness, simple installation, excellent performance characteristics and much more.
Customers who were dissatisfied with the purchase said that more effective and practical insulation materials can be found on the domestic market.
Thermal insulation at any temperature will not hurt. If done correctly, the rooms will become noticeably warmer in winter, and cooler in the summer heat. Insulating walls will help create a comfortable microclimate both in the apartment and in the work room. Manufacturers have tried their best and the types of insulation today shine with variety.
When you come to the market or a construction supermarket, you can only be surprised at the variety of insulation materials produced. They lie rolled into rolls and bundles, poured into containers in the form of granules, powders and perlite sand, and peek out from the packages like cotton wool. They are also made in the form of various cylinders, bricks, blocks and slabs. What to choose? In principle, what is primarily important is not the form, but the content. More on this later.
If you understand the characteristics of insulating materials, you can easily choose exactly the one you need. The main property of a heat insulator is its thermal conductivity. It shows how much heat can pass through a given material. There are two types of thermal insulation:
- Reflective insulation reduces heat consumption by reducing infrared radiation.
- Thermal insulation of the preventive type (it is used in most cases) involves the use of insulation with a low thermal conductivity value. In this capacity, one of three types of materials can be used: inorganic, organic or mixed.
Installation technology
There are several options for installing penoplex. Which one is better depends on the type and location of the insulated surface.
On glue
Special glue is applied to the surface of the base, after which the foam board is pressed tightly against it.
Fungus on dowels
The dowels securely fix the slabs if the installation rules are followed. It is important to correctly determine the required quantity. Dowel mushrooms (umbrellas) are used to fasten all the joints of the sheets, and two fasteners are also fixed in the middle of the slab.
On the foam
There is a special foam on the construction market that ensures reliable fastening of the penoplex to the base.
When insulating, it is better to combine options and use an adhesive base together with fastening dowels, especially for vertical bases.
Water absorption
The next important quality that you should pay attention to is water absorption. You can clearly evaluate this characteristic only by having a small sample of insulation with you. It is impossible to evaluate it by eye. You can conduct the experiment at home.
Place a piece of material in a container of water and leave for a day. For clarity, add a little dye or ink to the liquid. Afterwards, estimate how much water was absorbed into the insulation, and how much became in the vessel.
Some experts use the prick method when evaluating a product. Using a regular syringe, a little liquid is injected into the tissue. The smaller the spot size, the better and more practical the XPS finish.
Domestic analogues of the material
Domestic manufacturers produce extruded polystyrene foam, whose characteristics are not inferior to penoplex. At the same time, the cost of insulation differs, and you will be able to save money if you purchase an analogue.
Technoplex
Manufacturer TechnoNIKOL supplies Technoplex extruded polystyrene foam to the construction market. This insulation has greater heat-saving ability, since the manufacturer included graphite particles in the composition. But penoplex can withstand heavy loads.
Polyspen
According to the stated characteristics, Polyspen and Penoplex are similar. The first also presents several lines of material with different densities. At the same time, users note that the structure of materials with the same density parameter is significantly different and Polyspen is inferior to Penpolex.
Useful tips
Insulation using extruded polystyrene foam is effective and simple.
In order for the result to meet expectations, the main advice of professionals is to purchase high-quality thermal insulation materials from trusted suppliers and carry out insulation taking into account the rules and requirements.
By choosing the right adhesive mixture and calculating the required thickness of the insulation, using penoplex you can create a comfortable atmosphere in the house and additional protection outside. Moreover, such insulation will last more than half a century without loss of performance characteristics.
Dimensions
The production of extruded polystyrene foam is established in the form of slabs of standard sizes:
- length 1200 or 2400 mm;
- width 600 mm;
- thickness from 20 to 100 mm.
The blocks differ only in density and area of application. See the table for the dimensions and density of products from the brand:
