Thermal insulation of walls is a task that should be approached with special attention, because the materials for sheathing have different properties and "principle of operation", and it is very often presented on the market that no matter what insulator you take, there will be "Africa" in the room. In fact, this is not at all the case and you need to deal with each proposal in detail so as not to waste money, effort and time in vain.
Now usually use several types of heaters:
- in the form of rolls;
- rigid polystyrene boards;
- dense mats made of mineral wool.
The last two options, in principle, are quite understandable - these are really effective technologies, but also more expensive. But the rolled category of materials is not so unambiguous - this is where you need to figure it out in detail.
First, it is worth considering the main theoretical point.
What are rolled heat insulators
The first type of insulation made in the form of rolls is mineral wool materials. Vata itself happens on this basis:
- From cullet and quartz. This is the so-called glass wool, which is so common in Soviet-built houses.
- From rocks (for example, basalt);
- Cotton wool from blast-furnace waste.
It is recommended to use slag insulation only outside the walls, since there it does not cause any harm to health. But basalt products, in principle, can be laid indoors, the main thing is to pull a vapor barrier on top of them so that small fibers do not get into the air.
As for whether to insulate the walls with basalt wool from the outside or better from the inside, there is also no definite answer. The fact is that the material is afraid of moisture and if you mount it from the side of the facade, then you need to make good external protection (for example, from a vapor barrier and a metal profile). And this is expensive - if there are already such means, then it is better to use polystyrene foam or cotton wool in the form of plates.
But in general, basalt rolled insulation is still more relevant for use from the side of the room, because this way it lasts longer and better. The basic principle of action here is the retention of heat, that is, cotton wool, as it were, does not allow it to quickly go outside.
The second group is thermal insulation made of foamed polyethylene or polypropylene. The material is also produced in the form of rolls and can be of two types:
- foil coated;
- with metallized outside.
The first insulation is good because it has a good level of resistance to mechanical stress and reflects heat well. Due to this, the solution is suitable for indoor applications, for example, it is possible to mount the curtain behind radiators to retain heat. Among the shortcomings, one can single out poor vapor permeability and the fact that a foil of sufficient thickness will be expensive.
In addition, this thermal insulation is not suitable for direct contact with concrete walls - the alkali simply corrodes the foil.
Metallized products pass steam well, but they do not reflect heat efficiently enough. Topically used for wall cladding in shower rooms and rooms with high humidity. By the way, here the coating cannot be called resistant at all - the slightest mechanical impact and the metal begins to “peel off” from the base of the insulation. Now we can move on to the most important question.
So which option is better to choose: cotton wool or polyethylene foam
The main point that is important to understand is that foamed polyethylene or polypropylene in the form of rolls is exactly thermal insulation, that is, a material whose purpose is to slightly improve the characteristics of the walls, and not fully insulate them. Regardless of where it will be fixed - from the inside or from the front.
But basalt wool is already a real insulating layer. True, in the case of indoor use, the wall will still freeze through, just noticeably less heat will come out of the room.
It turns out that from the inside, polypropylene will give a lesser effect than cotton wool, since the temperature will rise only by a degree and a half. And even if you perform outdoor installation, then the “picture” will be the same, but with only one positive moment - the wall will freeze a little less and the condensate from the side of the room will disappear.
At the same time, the material has an undeniable advantage - it is cheap and it is very easy to mount it. It is more difficult and expensive to work with cotton wool, since it will be necessary to make a false wall (usually drywall) to protect the basalt fibers, and besides, it is important to take care that moisture does not get into the structure of the material. If this happens, then the effect of all the work done will be zero, since all thermal insulation qualities will disappear very quickly.
Here it seems to start to seem that cotton wool is better anyway (because it is “warmer”), but everything is decided by the nuances of the situation. Yes, cotton wool seems to be good, but what's the point in it if, for example, you need to insulate the shower room not in the house, but, for example, in the country and you don’t want to invest? The obvious budget solution in this case is a metallized insulator - stick it on the wall and forget it.
But in the case of a more or less capital approach, but again in the absence of significant financial resources, it is better to opt for mineral wool and insulation from the inside. It turns out that there is no ideal option and a decision needs to be made only based on the characteristics of the project.
Insulating boards do not show proper efficiency when insulating large areas, as well as pipes and ventilation ducts. This is due not only to their technical parameters, but also to their high density and rigidity, which excludes the possibility of high-quality coating of elements with complex geometry. In such a situation, it is more expedient to use rolled insulation, the varieties and features of which will be discussed in this material.
The materials of this group are the most common in the domestic market. This is due not only to their excellent operational and technical data, but also to an acceptable pricing policy - such a combination is still unattainable for competitive offers.
Flexibility makes work easier
Assortment and features of species
The term "mineral wool" is a unified designation for a number of heat insulators, namely:
- basalt wool - for the manufacture of this material, the technology of remelting certain rocks is used, followed by the formation of the finest fibers on their basis, woven into a single carpet;
- glass wool is a material, although it is obsolete, but still in high demand due to its affordable cost. For its production, remelted cullet glass is used;
- slag wool - it is based on waste obtained in the metallurgical industry. Due to this, such a heater in rolls has a lower cost than that of basalt and glass wool.
Material Specifications
Each of the varieties of mineral wool has its own distinctive features and characteristics. So, glass wool perfectly resists high temperatures, up to 450 degrees - after exceeding this parameter, the material is destroyed irreversibly. The highest density is 130 kg / m 3, thermal conductivity indicators vary in the range of 0.038–0.046 W / m * C.
Glass wool is not combustible, it does not even smolder, perfectly absorbs vibration manifestations, resists sound vibrations and does not shrink even during long-term operation. At the same time, the material is not moisture resistant, and its wetting completely eliminates the entire range of positive characteristics. It is worth noting the fragility of glass wool, as well as the fact that contact with human skin causes severe itching.
As for basalt wool, such rolled thermal insulation is able to withstand temperatures up to 700 degrees. Its thermal conductivity is 0.035–0.045 W / m * C, the density reaches 220 kg / m3. The material is resistant to moisture, slight wetting does not affect its parameters at all. Basalt wool is an environmentally friendly and non-irritating material.
Slag wool has the largest mass, and its density reaches 400 kg / m 3. The material is characterized by a minimum thermal conductivity - 0.046–0.048 W / m * C, and the highest temperature that it can withstand is 300 degrees - its increase causes the melting of slag and the destruction of its structure.
The dimensions of the materials largely depend on the manufacturer, but most often they have the following sizes:
- length - varies between 3-6 m and more;
- width - the standard figure is 0.6 and 1.2 m, although products of individual brands may have a width of 1.22 m and 0.61 m;
- thickness - 50, 100 and 150 mm.
Foil heat insulator and its properties
It is worth noting that manufacturers often cover the heat insulator on one side with a layer of foil, which makes it possible to protect the coating from the negative effects of ultraviolet rays and moisture penetration. Its use is advisable when warming the room from the inside, while the base can be made of a variety of materials.
The optimal solution for internal thermal protection
Types of insulation and features of each type
The substrate is made of foamed polyethylene, cork or expanded polystyrene. Expanded polystyrene is an affordable and very practical rolled foil insulation that does an excellent job of sound attenuation, does not have hygroscopicity and is able to dampen even minor vibration manifestations.
The Thermo-Tap heat insulator has excellent reviews among consumers, the roll length of which reaches 10 m with a width of 0.5 m. Practice shows that such a heater perfectly resists fungus and moisture, but at the same time has lower thermal insulation performance, inferior in this aspect polyethylene foam products.
It is impossible not to note the cork base for the heat insulator. The material is characterized by high strength, low weight, excellent aesthetic data and absolute harmlessness to humans. For rooms with a high level of humidity, it is recommended to use a cork substrate with wax impregnation. The length of the roll does not exceed 10 m, its width is 0.5 m.
Cork underlay is used for the floor
Foam-based polyethylene is a sheet consisting of tiny cells filled with air, covered with a layer of paper on top, which is attached by lamination. Thanks to this, it is possible to achieve the most durable and reliable connection with any type of base.
Frost protection heat insulator
The most common is the polyfoam rolled foam insulation, produced in rolls with the following dimensions: length - 14 m, width - 0.5 m, thickness 5 mm. Its density is 30 kg / m3, it perfectly absorbs sounds up to 22 dB, while offering a minimum thermal conductivity of 0.039 W / mK.
External coating and its relevance
The outer coating can be foil or have a metallized coating. Each of the options has its own characteristics, and its use can be justified in a given situation. So, the metallized material perfectly retains steam, but at the same time it does not have the highest heat reflection rates.
It is indispensable when carrying out insulation work in bathrooms and shower rooms, as well as other rooms with high humidity levels. It is worth noting that such a coating does not have high strength - even a slight mechanical impact is enough to violate its integrity.
Roll insulation with foil has excellent heat-reflecting data and is resistant to various kinds of external influences. It can easily be placed behind radiators in order to retain heat indoors.
Easy styling
As for the disadvantages, the foil insulation has poor vapor permeability, does not withstand direct contact with concrete, and the cost of a product with a thick layer of foil will be quite impressive.
The main advantages of a foil heat insulator
Among the main advantages of foil heat insulators, it is worth noting the following:
- excellent performance of thermal shielding, about 97%;
- good functionality and the possibility of using not only walls, ceilings and floors for insulation, but also all kinds of industrial units;
- minimum roll weight and ease of installation without the need to equip frames and other structures. Fastening is possible on building glue or ordinary mounting foam;
- acceptable cost;
- environmental friendliness and safety.
Mezhventsovy heat insulator and its features
There are also interventional rolled heaters, which are a rather specific solution designed to fill voids in the interventional space. A crown is a level in a house made of timber or logs. No matter how well the installation was carried out, including with the use of profiled timber, there remains free space between the crowns, just filled with this type of insulation.
It is produced in exceptionally narrow rolls, while it is always made from natural and harmless materials, including:
- batting;
- jute;
- linen and others.
The laying of the material is carried out not only during construction work, but also after several years after their completion - as the operation progresses, the tree dries out, which necessitates additional caulking (driving insulation into existing cracks using a wide chisel and mallet).
Manufacturers of heat insulators and their products
The greatest demand from the consumer is used by rolled insulation from several manufacturers.
Knauf is a German brand whose products do not contain formaldehyde, which gives the finished product absolute safety and harmlessness, which is relevant during installation work.
Rodents and insects do not start in such heaters, they have a wide assortment range, a long service life and the possibility of using not only apartments, but also country houses (cottages) for insulation.
Isover is a French manufacturer offering a wide range of roll insulation with excellent performance, including foil-coated. The products are suitable for carrying out thermal insulation measures both indoors and outdoors, it is not subject to combustion and is able to die out in case of fire.
Insulation for outdoor and indoor work
URSA - Spanish heaters under this brand are characterized by a long period of operation with full preservation of the main technical parameters. The manufacturer guarantees the highest quality of its products and its effectiveness in both private and industrial construction.
TechnoNIKOL is a Russian manufacturer offering high quality products at very affordable and affordable prices. These roll heaters are produced on the latest equipment using innovative technologies and techniques, which makes it possible to guarantee not only quality, but also a long service life.
When going shopping, it is worth remembering the following aspects of the choice:
- For indoor and outdoor use, various variations of insulation are suitable.
- The surface that will be covered with rolled thermal insulation also matters. There is a fundamental difference between the materials used to insulate the ceiling and walls. Each of these bases has its own insulation.
- It is also important to remember what material the walls are made of. A heat insulator for a wooden base may not be suitable for a concrete base and vice versa.
- When choosing the thickness of the material, it is worth taking into account the temperature conditions in the winter and the climate for a particular region.
- Before purchasing, it is imperative to familiarize yourself with the quality certificates and other permits for the selected roll insulation, and in addition, make sure that the packaging is intact. Moisture, even in small quantities, can adversely affect the design parameters of the material and its properties.
Choose quality material from trusted manufacturers
Heaters in rolls are presented on the market in a wide range. Each of them has its own characteristics, has positive and negative characteristics. The choice of a particular option is up to the user, but if there are difficulties, you should not rely on chance. It is better to seek help from professionals and save your nerves and money.
Hello dear friends! When choosing heat-insulating materials for a residential building and outbuildings, you probably paid attention to rolled insulation.
It is easy to use, its small thickness "does not steal" space, and the price in most cases is quite acceptable. Where and how can roll insulation be applied? What properties, advantages, disadvantages does it have? We will tell in this article.
Roll insulation refers to heat-insulating materials produced in rolls, based on expanded polystyrene foam or polyethylene. Now manufacturers are mastering the production of foamed roll materials based on environmentally friendly natural raw materials, such as rubber, cork, cellulose.
Rolled heat insulators based on polymeric materials are divided into two types:
- Insulation in rolls with foil, has high heat-preserving properties. The peculiarity of this type of insulation is that the layer of cellular polyethylene is covered with a layer of foil 0.5–2.0 mm. Such material is resistant to high temperatures up to +180 C.
- The usual finely porous insulation, produced in the form of rolls of various footage. In this case, the foil reflective layer is absent.
And also there are mineral-based roll insulation - these are mineral wool and basalt wool in rolls. In terms of properties and characteristics, these heaters are absolutely identical to ordinary mineral wool.
Heat insulators in rolls based on foamed polymers have the following properties:
- high level of environmental safety;
- durability, not subject to rotting, rodents and insects;
- excellent heat-preserving properties with a small thickness;
- low level of moisture absorption;
- good sound insulation;
- easy to install, cut into any parts and shapes without any problems.
Most heat insulators in rolls have a self-adhesive base, which makes it possible to further simplify the process of insulation and save on the purchase of adhesive composition.
Scope of roll insulation
Rolled heaters are used for thermal insulation of vertical and horizontal surfaces. Foil material is indispensable for creating thermal insulation in bath rooms, because it retains heat well and has heat-reflecting properties. And also this material has found wide application for thermal insulation of individual structures, joints, in hard-to-reach places.
Consider the main ways to use rolled heat insulators.
Rolled heat insulator for walls
Roll insulation for walls can be used as a heat-insulating material applied under decorative finishes, including wallpaper.
The application technology is very simple:
- self-adhesive material is glued to a wall prepared in advance, leveled and cleaned of debris and old finishes;
- a cement-based adhesive is applied to the heat insulator layer, resembling liquid plaster in properties;
- after the adhesive has hardened, you can start gluing the wallpaper.
The use of such material under the wallpaper will significantly increase the heat-preserving properties of the walls, as well as their sound insulation.
Roll heat insulator for the floor
It is used as a substrate for various types of decorative floor coverings. It has not only heat-insulating properties, but also gives the floor "softness", eliminates squeaks and sounds during shrinkage and movement of the floor covering.
In some cases, a foil heat insulator can be used to insulate the floor, this will increase heat retention, however, the cost of materials reinforced with foil is 30–60% more expensive.
The technology for the production of floor insulation using foamed polymer in rolls is very simple:
- the material is glued to a wooden floor or concrete screed using an adhesive composition or self-adhesive properties;
- leveled so that there were no "bubbles";
- the floor covering is laid on top.
The advantages of such a heat insulator include ease of installation, no debris, durability and environmental safety. When choosing a rolled heat insulator for the floor, it is worth remembering that the “softer” the floor covering, the denser the insulation should be.
In other words, it is better to use a polymer with maximum density under linoleum, otherwise, when walking, you will “sink” in the floor covering, but under a laminate or parquet, you can lay a polymer with any density.
Roof insulation roll
Suitable for thermal insulation of pitched and flat roofs. A roof insulated with such material will be warm for several decades. You can lay thermal insulation on your own, without involving highly paid specialists. The heat insulator is located between the elements of the roof truss system, while distortions, the formation of waves and other defects are not allowed.
In some cases, for example, when insulating a residential attic room or in regions with a cold climate, it is recommended to lay the insulation polymer in two layers.
The technology of work on the installation of thermal insulation of the roof depends on the design features. The best option is when thermal insulation is calculated at the design stage. In this case, the work boils down to the fact that the rolled material is rolled out and glued to the inner surface of the roof, a layer of vapor barrier material is laid on top and the final finish is arranged, for example, siding, lining, etc.
Conclusion
A rolled polymer heat insulator is an excellent option for increasing heat conservation indoors. It is easy to use, flexible, durable, and inexpensive. Foil material is indispensable for insulating a bath or sauna, as it has reflective properties and is moisture resistant.
The not always convenient and functional thermal insulation boards are replaced by an improved version of thermal insulation - rolled insulation, which is equally effective for both walls and ventilation ducts, pipes, roofs and other surfaces. The material has improved technical parameters and, unlike mineral wool in slabs with high rigidity and density, allows it to be used for elements with complex geometry.
The heater has high performance and technical characteristics, is sold at an affordable price. Rolled insulation is used both in repair and capital construction to improve the thermal insulation properties of surfaces:
- basement;
- attic
- balcony;
- gender;
- coverings, etc.
A standard mineral wool-based roll insulation for wallpaper on the walls in a living room allows you to increase the temperature by several degrees by reducing heat loss.
Additionally, the material prevents the development of dampness, the appearance of fungus and mold, and if there is an uneven surface, it hides flaws without additional work.
The wide scope of mineral wool in rolls allows us to talk about its versatility. The material is practically indispensable in modern areas of construction, it allows you to create a really working and durable layer of thermal insulation both in apartments and houses, and in outbuildings, at enterprises, saunas, baths, etc.
Particularly important is the ability of the material to come into contact with pipes and surfaces of ventilation shafts. In this case, rolled thermal insulation is arranged primarily due to the elasticity and flexibility of the material. Rolls are easy to use, allow you to finish uneven surfaces, including at sub-zero temperatures.
Advantages of thermal insulation in rolls
Comparing roll insulation with conventional mineral wool boards, the advantages of the former are obvious. These include:
- The minimum indicators of thermal conductivity, including among budget models.
- Resistance to atmospheric phenomena, temperature fluctuations, rodents and microorganisms while maintaining the main thermal insulation properties.
- A wide choice of material based on different types of mineral wool for warming surfaces with different performance characteristics and features.
- Resistance to high temperatures (up to 700 degrees Celsius), open flame.
- Noise-reducing properties, which allows you to increase the level of heat and sound insulation.
- Ease of installation.
There is also a small drawback in rolled thermal insulation based on mineral wool - high vapor conductivity, which will require a vapor barrier layer.
Types and characteristics of thermal insulation in rolls
At the heart of the insulation in rolls is mineral wool, which can be presented in several versions:
- in the form of basalt wool;
- glass wool;
- slag.
Materials based on basalt wool are created using the technology of remelting rocks with the formation of thin rocks woven into a single carpet on their basis.
For the manufacture of materials based on glass wool, remelted glass cullet is used, which can significantly reduce the cost of finished heat insulators.
For thermal insulation in rolls based on slag wool, mainly waste from the metallurgical industry is used. Compared to heaters based on the above-described heaters based on basalt wool and glass wool, it is the cheapest.
Each of the mentioned thermal insulation materials has its own set of characteristics, despite the fact that they are all an improved version of mineral wool. So, for example, glass wool is sufficiently resistant to high temperatures. The heat insulator is able to withstand up to 450 degrees Celsius, when the temperature rises above the specified mark, the surface is destroyed and cannot be restored.
Glass wool-based materials have the highest density and thermal conductivity. The rolls are not combustible, do not smolder, perfectly cope with vibration manifestations, suppress sound vibrations and, most importantly, do not shrink, regardless of the length of service life.
Of the minuses of materials based on fiberglass wool, it is worth noting the instability to moisture, as well as the unpleasant consequences that occur when it comes into contact with human skin.
Heat insulators based on basalt wool in rolls withstand high temperatures up to 700 degrees, have excellent thermal conductivity and density. Unlike fiberglass wool based heat insulators, materials are able to withstand moisture while maintaining basic performance characteristics even after getting wet. Heat insulators belong to the group of environmentally friendly materials that are not capable of causing allergic reactions.
Slag wool - thermal insulation for warming surfaces, the operating temperature of which does not exceed 300 degrees Celsius. The density of materials reaches 400 kg/m3, thermal conductivity ranges from 0.046 to 0.048 W/m*S.
The temperature exceeding the specified limit will lead to the melting of the slag with the destruction of the structure. Depending on the manufacturer, you can choose materials for thermal insulation based on slag wool with suitable parameters: length - from 3 to 6 m, width - from 0.6 to 1.2 meters, thickness - from 50 to 150 mm.
Heat insulator with a foil surface: features
Foil insulation materials have one main feature - the side with a layer of foil, designed to reduce surface exposure to ultraviolet rays and additional protection from moisture. Use materials for warming surfaces indoors with a base of different types of wool.
It is necessary to work with foil thermal insulation according to a special technology, observing some nuances, for example, not forgetting a small gap (no more than 1.5 cm) between the finish and the thermal insulation material. This is important, because when the temperature rises, the insulation will maintain the temperature, transferring it to the back wall, returning it back to the walls, but not to the room, as necessary.
Another important nuance is that, unlike heaters in rolls based on basalt, fiberglass or slag wool, the foil heat insulator is mounted on the crate, overlapping and treating the joints with insulating material.
Tips for choosing thermal insulation in rolls: what you need to know
Summing up all of the above, it remains to note several important nuances regarding the choice of materials based on roll-type mineral wool for insulation. Experts recommend first of all to take into account the type of surface and purpose. It is necessary to select materials suitable for thermal insulation of certain surfaces: wood, concrete, brick, etc.
Do not write off the thickness of the base, taking into account temperature indicators and precipitation in the region, especially when it comes to external insulation.
When buying materials for thermal insulation based on any of the listed types of wool, you should pay attention to the integrity of the package. It is strictly forbidden for moisture to form on the material in the packaging.
Each of the above types of insulators has its own characteristics, advantages and disadvantages, so the choice must be made after a thorough analysis of them, depending on the required functionality.
The widely used heat-insulating plates have been replaced by rolled heaters, which are more convenient and improved in functionality. Such products are suitable for finishing roofs, walls, utilities, ventilation shafts and other surfaces of complex shape. Rolled insulation has improved technical performance in comparison with mineral wool in slabs, it is characterized by increased density and rigidity.
The flexibility of the insulation will help you in the shortest possible time to complete the work on the insulation of your home
Flexible thermal insulation in rolls
The material has an affordable cost, excellent performance properties. The scope of its application is repair finishing and capital construction, when there is a need to increase the thermal insulation performance of surfaces:
- balcony;
- basement;
- gender;
- floors;
- attic.
Which insulation keeps heat better:
There are roll-type heaters based on mineral wool, which are glued to the walls directly under the wallpaper. Their main purpose is to increase the temperature inside the room, reducing natural heat loss in the cold season. Additionally, such materials prevent the development of mold and mildew, the formation of high humidity. The uneven surface is perfectly masked due to the soft insulation, which does not require finishing work.
Characteristic features and differences of heaters:
The versatility of rolled thermal insulation based on mineral wool determines the wide scope of its use. . It is indispensable in the modern construction industry., creates a durable working layer of insulation that protects from the cold:
- Living spaces;
- offices;
- warehouses in enterprises;
- outbuildings;
- baths and saunas.
Insulation, soundproofing walls for wallpaper:
Soft thermal insulation is not damaged by regular contact with ventilation ducts and pipelines. Due to sufficient flexibility, it tightly covers uneven surfaces, and can be laid at sub-zero temperatures.
Material Advantages
Thermal insulation in rolls designed with weaknesses in mind, which characterizes a similar material in slabs. It has a number of positive aspects:
- Minimization of thermal conductivity even among models belonging to the budget class.
- A large assortment range of roll insulation, which are based on various types of mineral wool. They differ in terms of performance.
- No damage by rodents, fungi, microorganisms.
The presence of a large assortment of heaters, will allow you to choose the best for you - Resistance to temperature extremes, adverse weather conditions while maintaining the original thermal insulation performance.
- Noise-reducing feature, resulting in increased sound insulation in the equipped room.
- Resistance to open fire.
- Ease of installation, which even an inexperienced master can handle.
Like other universal materials, soft insulation has a drawback. They are characterized by increased vapor conductivity, which can be eliminated by an additional layer of vapor barrier.
Main types and characteristics
The main component of the described materials is usually mineral wool. It, in turn, is presented in several versions:
- Slag. The insulation is made from waste from the metallurgical industry. It differs in strength indicators, while being the cheapest and most affordable product.
Slag wool is one of the cheapest materials that provides good thermal insulation. - Basalt wool. The peculiarity of heaters in rolls for walls and other surfaces is that they are produced using the rock melting technology. Then, thin layers are formed from the resulting content, intertwined into a single carpet.
- Glass wool. The heat insulator is created from pre-melted glass cullet. This approach to the production process significantly reduces the final price of the described products.
The disadvantage of glass wool is the increased fragility of the fibers that cause itching. Each of the designated heaters has a specific set of characteristics. But in any case, they all represent an improved version of the standard mineral wool. For example, glass wool exhibits excellent resistance to high temperatures: a heat insulator made from it can withstand up to +400°C. Exceeding this mark entails the complete destruction of the material with the impossibility of recovery.
Which heater is better:
As for the highest rates of thermal conductivity and density, they are typical for rolled insulation made of glass wool. It tolerates vibration manifestations well, does not smolder and does not burn, absorbs sound vibrations.
There is no shrinkage of such material throughout the entire operational period.
Of the unpleasant moments, there is irritation of human skin upon contact with fiberglass wool, slight instability to moisture.
The presence of the pros and cons of each of the materials will help you choose the best material for: home, cottage, bath Thermal insulation rolls made of basalt wool also withstand high temperatures, are distinguished by sufficient density and thermal conductivity. Excellent resistance to high humidity. Even when completely wet, the original quality indicators are preserved. Such material is completely environmentally friendly, does not cause irritation upon direct contact, does not cause allergic reactions.
The heat insulator made of slag wool can withstand a temperature load not exceeding +300°C. Otherwise, the slag melts, the structure of the described building product is completely destroyed.
Rolled thermal insulation materials differ in parameters and functionality. It all depends on the brand of products, the manufacturer, the requirements of the buyer in the manufacture of the product to order.
The role of the foil surface
The main feature of such insulation devices is the presence of a thin but durable foil coating. In this way, the material is protected from the negative effects of ultraviolet rays and high humidity, which is very important when equipping industrial premises, kitchens, bathrooms, baths, saunas.
Foil insulation tolerates high temperatures well Laying foil insulation is carried out in accordance with a special technological process. A gap of 1-1.5 cm is necessarily created between the thermal insulation and the finishing material. This is very important, since at elevated temperatures the insulation maintains a given degree by transferring it to the back wall and then returning back to the walls, but not to the room.
In comparison with roll materials made of slag wool, glass wool and basalt base, the foil product must be fixed on the crate. The layers are overlapped, the places of their joints are carefully treated with insulation.
When choosing a material, consult with a specialist, he will help you choose the best material Before buying soft thermal insulation for finishing a room for any purpose, you need to take into account some tips shared by experts. The features and type of the surface to be treated are important, which can be brick, concrete, wood, etc. An aspect such as the thickness of the base should not be overlooked when it comes to external insulation. In this case, the frequency and intensity of precipitation plays an important role., temperature regime by seasons.
A rolled heat insulator made on the basis of any type of mineral wool must be sold in undamaged packaging. Otherwise, moisture accumulates inside the material, worsening the quality of the product. When choosing the described material, its main functionality and purpose are taken into account.
Heaters in rolls - a demanded finishing product. They are easy to use, improve the thermal insulation of premises for various purposes, keeping it at the proper level for many years.
