Insulation materials: how to create weather in the house. General technical and comparative information (PPU) Comparison of the most modern options

What is thermal conductivity? Knowing about this value is necessary not only for professional builders, but also for ordinary people who decide to build a house on their own.

Each material used in construction has its own indicator of this value. Its lowest value is for heaters, the highest for metals. Therefore, it is necessary to know the formula that will help calculate the thickness of both the walls being built and the thermal insulation in order to end up with a cozy home.

Comparison of heat conductivity in the most common heaters

To understand the conduction of heat different materials intended for insulation, you need to compare their coefficients (W / m * K), given in the following table:

As can be seen from the above data, the heat conductivity index of such building materials, as thermal insulation, varies from the minimum (0.019) to the maximum (0.5). All thermal insulation materials have a certain variation in readings. SNiPs describe each of them in several forms - in dry, normal and wet. The minimum coefficient of heat conductivity corresponds to a dry state, the maximum - to a wet one.

If individual construction is planned

When building a house, it is important to consider specifications all components (material for walls, masonry mortar, future insulation, waterproofing and steam-removing films, finishing).

To understand which walls the best way will retain heat, it is necessary to analyze the thermal conductivity of not only the material for the walls, but also mortar which can be seen from the table below:

Important . From the data given in the table, it can be seen that each building material has a rather large spread in terms of the thermal conductivity coefficient.

This is due to several reasons:

• Density. All heaters are produced or stacked (penoizol, ecowool) different density. The lower the density (more air is present in the thermal insulation structure), the lower the heat conductivity. Conversely, for very dense insulation, this coefficient is higher.
• The substance from which they are made (base). For example, brick is silicate, ceramic, clay. The coefficient of thermal conductivity also depends on this.
• The number of voids. This applies to bricks (hollow and solid) and thermal insulation. Air is the worst conductor of heat. Its thermal conductivity coefficient is 0.026. The more voids, the lower this figure.

Mortar conducts heat well, so any walls are recommended to be insulated.

If you explain on the fingers

For clarity and understanding of what thermal conductivity is, you can compare a brick wall with a thickness of 2 m 10 cm with other materials. Thus, 2.1 meters of brick stacked into a wall on a conventional cement-sand mortar are equal:

• a wall 0.9 m thick made of expanded clay concrete;
• timber, with a diameter of 0.53 m;
• wall, 0.44 m thick from aerated concrete.

When it comes to such common heaters as mineral wool and polystyrene foam, then only 0.18 m of the first thermal insulation or 0.12 m of the second is required, so that the thermal conductivity values ​​\u200b\u200bare huge brick wall turned out to be equal to a thin layer of thermal insulation.

Comparative characteristics of the thermal conductivity of insulating, building and finishing materials, which can be produced by studying SNiPs, allows you to analyze and correctly compose an insulation cake (base, insulation, finishing). The lower the thermal conductivity, the higher the price. A prime example the walls of the house, made of ceramic blocks or ordinary high-quality bricks, can serve. The former have a thermal conductivity of only 0.14 - 0.18 and are much more expensive than any of the best bricks.

Any construction works start by creating a project. At the same time, both the location of the rooms in the building and the main heat engineering indicators are calculated. From these values ​​​​depends how the future building will be warm, durable and economical. It will allow you to determine the thermal conductivity of building materials - a table that displays the main coefficients. Correct calculations are a guarantee of successful construction and the creation of a favorable microclimate in the room.

In order for the house to be warm without insulation, a certain wall thickness will be required, which differs depending on the type of material.

Thermal conduction is the process of transferring thermal energy from warm parts to cold parts. Exchange processes occur until complete equilibrium of the temperature value.

Therefore, when building a building, it is worth using additional materials. In this case, the thermal conductivity of building materials is important, the table shows all the values.

Helpful information! For buildings made of wood and foam concrete, it is not necessary to use additional insulation. Even using low-conductivity material, the thickness of the structure should not be less than 50 cm.

Features of the thermal conductivity of the finished structure

When planning a project for a future home, it is necessary to take into account the possible loss of thermal energy. Most of the heat escapes through doors, windows, walls, roofs and floors.

If you do not perform calculations for heat saving at home, then the room will be cool. It is recommended that buildings made of concrete and stone be additionally insulated.

Helpful advice! Before insulating a home, it is necessary to consider high-quality waterproofing. At the same time, even high humidity will not affect the features of thermal insulation in the room.

Varieties of insulation structures

A warm building will be obtained with an optimal combination of construction from durable materials and high-quality heat-insulating layer. Such structures include the following:

• building from standard materials: cinder blocks or bricks. In this case, insulation is often carried out on the outside.

How to determine the thermal conductivity of building materials: table

Helps to determine the thermal conductivity of building materials - table. It contains all the values ​​​​of the most common materials. Using such data, you can calculate the thickness of the walls and the insulation used. Table of thermal conductivity values:

To determine the value of thermal conductivity, special GOSTs are used. The value of this indicator differs depending on the type of concrete. If the material has an index of 1.75, then the porous composition has a value of 1.4. If the solution is made using crushed stone, then its value is 1.3.

loss through ceiling structures significant for those living on the upper floors. The weak areas include the space between the floors and the wall. Such areas are considered cold bridges. If there is a technical floor above the apartment, then the loss of thermal energy is less.

The top floor is made outside. Also, the ceiling can be insulated inside the apartment. For this, expanded polystyrene or heat-insulating plates are used.

Before insulating any surfaces, it is worth knowing the thermal conductivity of building materials, the SNiP table will help with this. insulate flooring not as difficult as other surfaces. Materials such as expanded clay, glass wool or expanded polystyrene are used as insulating materials.

Modern insulation materials have unique characteristics and are used to solve problems of a certain spectrum. Most of them are designed for processing the walls of the house, but there are also specific ones designed for arranging door and window openings, roof junctions with load-bearing supports, basements and attics. Thus, when comparing thermal insulation materials, it is necessary to take into account not only their operational properties but also the scope.

Main parameters

The quality of the material can be assessed based on several fundamental characteristics. The first of these is the coefficient of thermal conductivity, which is denoted by the symbol "lambda" (ι). This coefficient shows how much heat passes through a piece of material with a thickness of 1 meter and an area of ​​1 m² in 1 hour, provided that the difference between the temperatures of the environment on both surfaces is 10 ° C.

The indicators of the thermal conductivity coefficient of any heaters depend on many factors - on humidity, vapor permeability, heat capacity, porosity and other characteristics of the material.

moisture sensitivity

Humidity is the amount of moisture contained in the insulation. Water is an excellent conductor of heat, and the surface saturated with it will contribute to the cooling of the room. Consequently, waterlogged heat-insulating material will lose its qualities and will not give the desired effect. And vice versa: the more water-repellent properties it has, the better.

Vapor permeability is a parameter close to humidity. AT in numerical terms it represents the volume of water vapor passing through 1 m2 of insulation in 1 hour, subject to the condition that the difference in potential vapor pressure is 1 Pa, and the temperature of the medium is the same.

With high vapor permeability, the material can be moistened. In this regard, when insulating the walls and ceilings of the house, it is recommended to install a vapor barrier coating.

Water absorption - the ability of a product to absorb liquid when in contact with it. The water absorption coefficient is very important for materials that are used for arranging external thermal insulation. high humidity air, atmospheric precipitation and dew can lead to deterioration of material characteristics.

Density and heat capacity

Porosity is the number of air pores expressed as a percentage of the total volume of the product. Distinguish pores closed and open, large and small. It is important that they are evenly distributed in the structure of the material: this indicates the quality of the product. Porosity can sometimes reach 50%, in the case of some types of cellular plastics, this figure is 90-98%.

Density is one of the characteristics that affect the mass of a material. A special table will help determine both of these parameters. Knowing the density, you can calculate how much the load on the walls of the house or its floors will increase.

Heat capacity - an indicator showing how much heat is ready to accumulate thermal insulation. Biostability - the ability of a material to resist the effects of biological factors, such as pathogenic flora. Fire resistance - the resistance of insulation to fire, while this parameter should not be confused with fire safety. There are other characteristics, which include strength, bending endurance, frost resistance, wear resistance.

Also, when performing calculations, you need to know the coefficient U - the resistance of structures to heat transfer. This indicator has nothing to do with the qualities of the materials themselves, but you need to know it in order to make right choice among various heaters. The coefficient U is the ratio of the temperature difference on both sides of the insulation to the volume of heat flow passing through it. To find the thermal resistance of walls and ceilings, you need a table where the thermal conductivity of building materials is calculated.

You can do the necessary calculations yourself. To do this, the thickness of the material layer is divided by the coefficient of its thermal conductivity. The last parameter - if we are talking about insulation - must be indicated on the packaging of the material. In the case of house structural elements, everything is a little more complicated: although their thickness can be measured independently, the thermal conductivity of concrete, wood or brick will have to be sought in specialized manuals.

At the same time, materials of different types are often used to insulate walls, ceilings and floors in the same room, since the coefficient of thermal conductivity must be calculated separately for each plane.

Thermal conductivity of the main types of insulation

Based on the U coefficient, you can choose which type of thermal insulation is better to use, and what thickness the material layer should have. The table below contains information about the density, vapor permeability and thermal conductivity of popular heaters:

Advantages and disadvantages

When choosing thermal insulation, it is necessary to take into account not only its physical properties, but also parameters such as ease of installation, the need for additional maintenance, durability and cost.

Comparison of the most modern options

As practice shows, it is easiest to carry out the installation of polyurethane foam and penoizol, which are applied to the treated surface in the form of foam. These materials are plastic, they easily fill the cavities inside the walls of the building. The disadvantage of foamable substances is the need to use special equipment for spraying them.

As the table above shows, extruded polystyrene foam is a worthy competitor to polyurethane foam. This material comes in solid blocks, but can be cut into any shape with a regular carpenter's knife. Comparing the characteristics of foam and solid polymers, it is worth noting that the foam does not form seams, and this is its main advantage compared to blocks.

Comparison of cotton materials

Mineral wool is similar in properties to foam plastics and expanded polystyrene, but at the same time it “breathes” and does not burn. It also has better resistance to moisture and practically does not change its quality during operation. If there is a choice between solid polymers and mineral wool, it is better to give preference to the latter.

At the stone wool comparative characteristics the same as that of the mineral, but the cost is higher. Ecowool has acceptable price and is easy to install, but has low compressive strength and sags over time. Fiberglass also sags and, in addition, crumbles.

Bulk and organic materials

For thermal insulation of the house, bulk materials are sometimes used - perlite and paper granules. They repel water and are resistant to pathogenic factors. Perlite is environmentally friendly, it does not burn and does not settle. However, bulk materials are rarely used for wall insulation; it is better to equip floors and ceilings with their help.

From organic materials, it is necessary to distinguish flax, wood fiber and cork. They are safe for environment, but are prone to burning unless impregnated with special substances. In addition, wood fiber is exposed to biological factors.

In general, if we take into account the cost, practicality, thermal conductivity and durability of heaters, then the best materials for finishing walls and ceilings - these are polyurethane foam, penoizol and mineral wool. Other types of insulation have specific properties, as they are designed for non-standard situations, and it is recommended to use such insulation only if there are no other options.

The roof, according to Euromet specialists, is the top element of the building, an engineering structure that protects the interior from atmospheric influences. It has the following components.

Basic structure. It takes on mechanical loads, provides strength and rigidity of the roof, is made of wooden elements, metal profiled sheet, concrete, precast concrete etc.

Vapor barrier. Provides removal of evaporation from the premises, protects the elements of the roof from getting wet, condensation.

Thermal insulation. Prevents the removal of heat from the premises.

Waterproofing. Protects roofing cake and interiors from atmospheric moisture.

Accessories. Fasteners for roofing elements, accessories, other elements.

Assembly passages. Used for arranging communications and their exits to the roof surface, ventilation.

architectural elements , ventilation, ventilation outlets.

These components are selected so as to create a single engineering system. It must be resistant to any negative influences, participate in maintaining a healthy microclimate inside the building. Yes, at proper arrangement waterproofing atmospheric moisture, precipitation does not penetrate into the building. Quality protects roof structures from moisture that accumulates inside the premises.

Thermal insulation - essential element roof structure. It performs the following functions:

• heat loss protection interior spaces through the use of materials with high resistance to heat transfer;
• base for installation of waterproofing;
• compensation of loads on the roof (weight of snow, strong wind, operational factors, etc.);
• abduction excess moisture, maintaining a stable level of pressure of the generated steam;
• prevention of deformations that are associated with temperature differences;
• Fire safety.

Competent arrangement of thermal insulation and use quality materials create optimal conditions building operation. At the same time, indicators of air humidity, temperature, water vapor pressure inside and outside are in optimal balance.

The influence of humidity on the characteristics of the roof

The design of the roof performs enclosing functions. The materials from which it is made are not completely dry during operation, they have a certain level of moisture. The state of moisture can be liquid, gaseous (steam), solid (ice). It depends on the temperature of the roofing materials. AT winter period thermal backwater is formed due to space heating. In summer, heating occurs under the influence of sun rays. As a result of these processes, water vapor is formed. The more intense the heating, the higher the steam pressure. It can provoke the gradual destruction of the roof structure. So, this is manifested by the appearance of swelling: steam accumulates under the roofing and “raises” it in some areas.

When designing a roof, it is important to prevent the appearance of areas of moisture, water accumulation. This will protect the waterproofing from destruction when the liquid freezes in winter and the vapor pressure rises in summer. Moisturizing roofing materials dangerous increase in thermal conductivity. Maintaining the humidity at a normal level will ensure effective thermal insulation and extend the life of the roof. To achieve this, when designing a roof, attention is paid to the quality of insulation and their compatibility with other elements of the building envelope.

hydrophobicity

The level of thermal insulation properties of the roof structure is determined by the following factors:

• thermal conductivity of materials;
• air permeability of the structure;
• vapor permeability;
• resistance to deformation, damage, mechanical stress;
• compatibility of roof elements and the correctness of their location;
• quality of installation work.

Paroc products are used for roof insulation. They are made from mineral wool with special structure. The material has fibers no thicker than 4 microns, evenly distributed and interlaced in random order. The spaces between the fibers are filled with still air. It has a low coefficient of thermal conductivity (at a temperature of +10°C - only 0.026 W/m°C). The intrinsic thermal conductivity of heaters is also at a low level (within 0.032-0.045 W/m°C).

Operating conditions affect the value of the thermal conductivity coefficient. Therefore, the indicator is measured separately for dry, moist material, etc. The coefficient of thermal conductivity of water is 20 times higher than that of air. If water gets inside the stone wool and lingers in it, the contact area of ​​the fibers increases. The number of air cells is reduced. This leads to a decrease in thermal insulation properties.

Wetting of building materials occurs due to condensation, moisture sorption, capillary moisture. Regulations(SNiP 23-02-2003 and others) require taking into account the features of operating conditions when calculating thermal conductivity indicators. In particular, the calculation takes into account the relative humidity of the air inside the building. With proper design of the roof structure, the effect of moisture on its characteristics is reduced.

Sorption (moisture absorption by the material from the air) remains the main factor in moistening the building envelope. Sorption process going faster when the air temperature decreases and the relative humidity increases. Paroc products are protected from this. The moisture level as a result of sorption for it was measured according to GOST 24816 and amounted to 0.07-0.54%. Such a low rate guarantees minimal absorption of moisture by roof structures.

Such indicators are achieved due to the hydrophobic properties of Paroc fibers. The fiber has chemical composition with water repellent properties. Moisture resistance level - pH=1.2-1.8. Additionally hydrophobic properties increase due to the introduction of additives into the raw materials. During sorption at 97% air humidity, Paroc ROS/ROB 60 materials absorb 0.23% of moisture from own weight(tests according to GOST 24816). Paroc insulation fibers do not contain slags. The manufacturer does not use them to avoid reducing the quality of raw materials and increasing moisture absorption. This provides excellent performance thermal insulation materials.

Resistance to chemical elements

Paroc mineral wool insulation, which you can buy from Euromet at favorable price, is a high level of chemical resistance:

• resistance to moderately acidic compounds and media, oils, solvents;
• lack of destruction upon contact with the free alkaline component (it is released during the arrangement of the screed);
• neutral characteristics of the hood from Paroc products. Due to this, the surfaces in contact with the insulation are not subject to the development of rust.

Such indicators are provided by the natural composition of the raw materials of Paroc heaters. For the manufacture of mineral wool, only components of natural origin are used.

Advantages of Paroc materials

Paroc produces a range of insulation products for roof structures. In the line of materials - elastic plates, which are recommended for pitched roofs. Combined roofs are insulated using rigid slabs. Paroc products are selected according to the type of construction. Permissible compressive force - 5-80 kPa, concentrated force - up to 700 N. Hereinafter, the indicators are given for 10% deformation.

Fire safety

Mineral wool fibers are made from basic rocks. The main component is basalt with a melting point of 1500°C. The fibers are sintered at temperatures above 1000°C. Due to this, Paroc heaters can be used with increased requirements for fire safety. They have improved fire resistance.

Paroc products have passed a number of tests in Russia and CIS countries. As a result of tests according to DIN 4102, ISO 1182 and other standards, the materials are recognized as non-combustible. According to the classification of GOST 30244-94, they are classified as KM0.

Quality control

Paroc production is ISO 9001:2008 certified. This guarantees strict quality control and excellent performance. Products do not shrink, retain their dimensions. During the service life, no deformation occurs. This prevents the formation of cold bridges at the joints, provides high-quality insulation.

Security

When laid and used, Paroc products are safe for human health and the environment. This is confirmed by the hygienic conclusions issued in Russia. The products are biologically safe, and the corresponding CE marking is applied to the packaging.

Certification

Paroc products are certified in Russia, a number of EU and CIS countries. The characteristics of the plates allow for correct heat engineering calculations according to current rules, standards and regulations.

Insulation of a standard combined roof

Flat roofs have little or no slope at all. Often used in the construction of industrial and civil facilities, valued for durability and reliability. There may be an attic under the roof. If it is not there, the roof structure is called combined. When arranging a standard roof, a layer of insulation is placed under waterproofing material. The design in this case is formed by the following layers: base with bearing characteristics; a layer that forms a slope; ventilation devices; heat and vapor barrier layers; fixing accessories; waterproofing layer. The listed layers provide drainage excess moisture. Its accumulation can reach 10-20% of the volume or 10-20 mm/m2. The exact amount of accumulation depends on the thickness of the insulating material. If in top layer the insulation comes into contact with the waterproofing material, moisture will accumulate in the thermal insulation. To avoid this and ensure the normal operation of the building envelope, it is equipped so that the heat-insulating plate is effectively dried. The moisture accumulating in the roof structure is removed by evaporation when the air is heated. Using this, Paroc specialists created the Paroc Air system. AT insulating layer ventilation ducts are provided, through which moisture is effectively removed. This improves the characteristics of standard combined roofs, extending their service life. When insulated with Paroc Air, the drying rate of roofing materials is 0.5 kg/m2 per day.

Insulation of two-layer combined roofs

The layered structure of the roof of this type: base with load-bearing functions (profiled sheet or reinforced concrete panels are used); vapor barrier membrane or film; two-layer insulation; waterproofing layer. For the bottom layer of insulation use board materials ROS 30, ROS 40 (semi-rigid). These heaters have a low density and improved mechanical characteristics. Permissible compressive force - 30 kPa, density not more than 110 kg/m3. ROB 60 and ROB 30 boards are rigid boards (density not more than 180 kg/m3). Permissible compressive force is 2.5 times higher - up to 80 kPa. They are used to form the top layer of insulation, which distributes the mechanical load over the roof structure. For Paroc products, deformations up to 15% are reversible. With such an impact, the materials restore their original size and shape after its termination. The two-layer system involves laying with dressing joints to reduce the number of cold bridges. It reduces the load on the base and increases thermal insulation characteristics roof structure.

The table shows allowable thickness thermal insulation for corrugated board with different width waves.

Paroc Air - the solution for combined roof ventilation

Paroc Air has been patented. This is an innovative solution that serves to equip "eternal" roofs.

Materials for insulation of combined roofs

The Paroc product line includes board materials for single-layer and two-layer insulation systems. For single-layer systems, ROS 50, ROS 60 boards are used, which you can purchase from Euromet. These materials are hydrophobic, have high strength and reliably protect the building from heat loss through the roof. When arranging a single-layer thermal insulation system, waterproofing coatings can be used different types(bituminous, metal on a substrate, polymeric, etc.).

When arranging two-layer systems, it becomes possible to vary the properties and characteristics of the roof. For the bottom layer, ROS 30 (g) or ROS 40 (g) boards with a thickness of 5-20 cm are used. The top layer is load-bearing and is made of ROB 80t or ROB 60 material. high level. Raw materials for heaters - stone wool with fibers 4 µm thick. This ensures maximum heat retention. When installing two-layer systems, plates with ventilation ducts are used for the lower layer. Steam, moist air is discharged through them, which keeps the entire system dry.

Abbreviations in the names of products mean the name of the thermal insulation system, its purpose and the indicator of the allowable compressive force. So, ROS 60 stands for Roof Slab, the maximum allowable compressive force is 60 kPa.

Materials ROB 60, ROS 60, ROB 80t are rigid boards, the top layer of which has microlamellarization. This is a special surface structure that increases adhesion during the installation of welded coatings.

Paroc uses ultra-high-speed multi-roll centrifugal processing of raw materials in its production. It ensures the minimum thickness of the fibers. The peel strength at the top layer of the material is more than 5 kPa (according to GOST 17177, EN 1607). This indicator is constantly monitored in the production of Paroc.

The manufacturer offers no-required pre-training plate materials for roof insulation. If welded waterproofing is used in the arrangement of the roof, it is not necessary to apply a primer to the insulation. Improved binder recipes mineral wool insulation increase the elasticity of the fibers and exclude the destruction of bitumen under the action of phenolic alcohol compounds.

** σ mt - peel strength of layers.

* µ - vapor permeability coefficient.

Space under pitched roofs use, equipping for this attic. Such structures are complex and require high-quality insulation. If a attic space are not used, then the requirements for the microclimate inside residential attics are very strict: here it is necessary to maintain the specified parameters of humidity and air temperature.

Attics have a specific design of external fences. They are formed by the roof in whole or in part. The roof itself, therefore, must isolate both the attic and the entire building from precipitation, prevent heat loss, and ensure a normal level of hygienic indicators.

The processes operating in attic enclosures are subject to the laws of building thermal physics. For example, warm indoor air contains more moisture than cold outdoor air. Because of this, evaporation is directed from the inside to the outside. Steam diffuses from the premises through the roofing materials into the atmosphere. The bottom layer of the roof structure performs waterproofing functions. It does not allow water vapor to pass out and provokes moisture condensation. It occurs when moisture-saturated air comes into contact with a cooled surface. At this point, the humidified air cannot hold moisture, and it settles on the surface and forms dew. Further, the dew flows or forms drops, which causes the materials in the inner layers of the structure to get wet.

To protect the thermal insulation and other layers of the roof structure, anti-condensation is used. diffusion film. In the top layer of this material - waterproofing coating. The bottom layer absorbs moisture.

When exposed to moisture on the insulation thermal insulation properties are declining. To avoid this, when arranging thermal insulation, do the following:

• arrangement of vapor barrier. Films or membranes are attached to heat-insulating boards to protect them from dampening with steam from the premises;
• creating layers of air between the waterproofing material and the insulation. Due to these layers, the moisture that enters the heat-insulating layer later evaporates from it.

For maximum effective protection insulation from moisture equip two-level ventilation inside the structure. The first level is located under the roof covering, above the waterproofing layer. The second level is a layer of air under the waterproofing and above the insulation. In order for moisture to be effectively removed, the air in these levels must circulate. To achieve this, when arranging ventilation system leave outlets and inlets. Such a system allows you to comprehensively remove moisture. The insulation is protected from condensate, moisture settling during the diffusion of steam and moist air from the external environment.

When arranging attic rooms Euromet specialists do not recommend completely isolating roof structures. To ensure their durability, a second level of ventilation is required. The most effective roofing structures are considered, in which the ridge is divided. When designing the roof, separately functioning air cavities are formed, which remove moist air into the ventilation ducts.

Additionally, a wind protection layer is recommended. For this, windproof vapor-permeable films are used. They increase the effectiveness of thermal insulation due to the fact that ascending air currents do not blow heat out of the insulation. Wind protection is placed on the insulation from the side of the air gap.

When insulating the attic, it must be taken into account that the building envelope is formed not only by the roof, but also by the gables. To exclude heat loss through them, the gables are insulated. When choosing thermal insulation material they take into account:

• the effect of wind loads (blowing heat, destruction of insulation);
• resistance of the material to vertical loads (it should not crumble, settle);
• the own weight of the material should be minimal with maximum thermal insulation properties;
• compliance with the requirements for fire and refractory properties;
• the quality of sound insulation provided by the insulation.

A well-designed, high-quality Paroc thermal insulation system ensures that all these requirements are met.

Paroc attic insulation system

Paroc eXtra - mineral wool boards. They are laid in the main layer of thermal insulation. Additionally used as fire protection and soundproofing. The material is universal, can be installed in frame structures made of metal, wood. Installation is quick and easy, the material is durable and safe. It has the following advantages. High quality insulation. Low density and light weight. It does not deform, does not settle, does not collapse over time. Thermal insulation is elastic, which simplifies installation. The plate fills the space, it fits snugly to the structural elements without forming gaps. Due to this, cold bridges are not formed at the joints of the thermal insulation. Simple processing. Cutting is carried out with an ordinary knife with a margin in width (2% more than required). Next, the plates are compressed and installed in the space for them. Security. The insulation does not contain toxic substances, the fibers are biodegradable, their particles are excreted from the human body. High fire-fighting properties. The material is non-combustible and can be used as fire protection. Hydrophobicity. The special structure of the raw material and the introduction of a number of additives into its composition provides the boards with water-repellent properties. The insulation stays dry and “works” as efficiently as possible. Quality soundproofing. It is acceptable to use Paroc eXtra to create soundproof systems.

Paroc WAS 25(t) is used to form a wind protection layer. The material prevents the blowing of heat from the main layer of insulation, increases the efficiency of insulation. Wind and vapor barriers are installed close to the thermal insulation. When installing a vapor barrier in the main layer of insulation, it becomes the boundary of the layers. In this case, the thermal insulation characteristics in the outer layer should be 3 times higher than those of the base layer.

When insulating the attic, follow the manufacturer's instructions for working with Paroc materials. High-quality and competent installation increases the efficiency and durability of the thermal insulation system.
