The pipe insulation is foil-wrapped. Types and features of foil thermal insulation of pipes. How is the correct thermal insulation of heating pipes

Thermal insulation of pipelines is one of the important measures to ensure the durability of steel (VGP; ES; BSH) and polymer pipes.

Section materials

The thermal insulation of heating pipes is no less important than the thermal insulation of the basement, walls or roof of a building. The main reason for this is the uninterrupted supply of water during the cold season, so it is simply necessary to insulate the water supply.

How is the correct thermal insulation of heating pipes?

Depending on the material used, thermal insulation for pipes differs in structure and production technology.

Selection and installation of thermal insulation of pipes is a matter only for an experienced specialist. Otherwise, over time, you will need to redo the work done again.

To ensure a long period of operation of the pipeline, it is always necessary to take into account the climatic conditions in which the operation of heating or water supply networks will be carried out, and to trust the installation of the material only to professionals.

Thermal insulation of water supply pipes is the most important stage in the creation of water supply or sewerage systems. Proper thermal insulation of pipes guarantees the normal functioning of the pipeline even in the cold season. Haste and savings on insulation leads to the need for regular repairs.

For thermal insulation of pipelines, only high-quality materials should be chosen. It should also be taken into account that it is important not only to protect the pipe from the effects of cold, but also to provide protection against corrosion by creating an anti-corrosion layer.

It should be remembered that the thermal insulation of pipes must have a long service life so that there is no need for frequent replacement. Depending on the passage of the pipeline (external or underground), different types of pipe insulation are used.

For indoor applications, it is optimal to use ROCKWOOL thermal insulation cylinders. Products from a well-known manufacturer, have high quality and unique properties. High requirements for technical insulation products allow Rockwool cylinders to be No. 1 today. They are made from mineral wool on a synthetic binder 1 meter long. They can be of various diameters from 19 to 273 mm. The thickness of hollow products can be 30, 40, 50, 60, 70 and 80 mm. Cylinders can be produced with additional aluminum foil coating.

For outdoor use, Rockwool mineral wool cylinders can also be used, but with subsequent shelter in the form of protective shells. They protect products from atmospheric precipitation and damage to thermal insulation. It is also possible to use mineral wool mats Tech mat and Wired Mat.

Thermal insulation for pipes can also be made with PPU shells or polystyrene foam shells. For in-ground applications, this is the most common insulation option. In any case, all necessary measures to protect pipes are recommended to be carried out strictly according to the project, which specifies certain materials necessary for insulation.

Thermal insulation of heating pipes is a reliable protection for pipes. The efficiency of heating mains depends on the heat-insulating material, because without it, heat loss occurs, especially in winter. All this is reflected in the wallets of our citizens.

Acceptable prices for pipe insulation

Today, you can buy thermal insulation for pipes at various prices. When choosing one or another material, the buyer is often interested in what determines the price of insulation for the pipeline. The answer to the question is simple.

The cost of the material is affected by the following:

• √ producer country - imports are always more expensive than domestic goods, although they are the same in quality;
• √ the density of the material - the denser, the more expensive;
• √ thermal insulation thickness;
• √ the ratio "pipeline insulation - price" depends entirely on the structural material;
• √ Bulk purchase is always cheaper than retail.

However, when buying thermal insulation for pipes, you should choose only the product that is best suited for these specific operating conditions. In this case, having paid once, the buyer will enjoy the uninterrupted operation of the pipeline for a long time.

In preparation for the work on the thermal insulation of the house, the question arises of choosing the optimal insulation. For an ignorant person, it is not easy to decide on a wide variety of thermal insulation materials. That is why, when going for a purchase, you need to prepare in advance: clarify the features of a particular insulation and the scope of its use, technical characteristics, etc.

A comfortable temperature in the house is often provided using porous or fibrous materials with low thermal conductivity. However, heaters that work on a different principle - on the reflectivity of a mirror surface began to gain more and more popularity. This is how foil thermal insulation works, which today is considered the most effective.

What is thermal insulation with foil

This is a combined insulation, which, in addition to the base base with low thermal conductivity, has a reflective layer of very thin, about 20-30 Å (angstrom), polished aluminum foil. This component provides the maximum effect of reflection of infrared rays, in fact, heat - up to 97%, and the base layer "takes over" the remaining 3%. Thus, the heat remains in the room.

Types of heaters

Foil thermal insulation has a variety of forms - in the form of rolls, mats, tiles, cylinders, used mainly for thermal insulation of pipes, and sizes. They differ in other respects as well.

• View of the base layer.

• foam polyethylene,
• mineral or basalt wool;
• expanded polystyrene.

• Insulation foil technology. Aluminum foil for thermal insulation can be glued or sprayed, perforated or not.

• Number of reflective layers. On some types of thermal insulation, the foil can be applied on one or both sides, on others there is an adhesive layer, that is, in addition, such thermal insulation reflects, it can be laid directly on the surface without. These heaters are labeled respectively A, B and C.

On a note

Since self-adhesive foil thermal insulation is quite flexible, it can be used for laying in corners, as well as on uneven surfaces. By gluing the connecting seams of heat insulators with foil tape, you can achieve their complete tightness.

• Appointment. Thermal insulation materials coated with foil are used both as the main thermal insulation and additional.

For those who are going to buy thermal insulation, we note that the price of foil insulation is formed depending on such parameters as:

• base material;
• aluminum foil thickness;
• height of the heat-insulating layer;
• number of reflective screens.

Advantages and disadvantages

• The foil has an excellent ability to reflect thermal radiation as much as possible. On the one hand, it retains heat in the room, on the other hand, it does not let heat in, that is, a “thermos effect” is created inside.
• An additional layer of foil increases the wear resistance of the insulation.
• It has hydrophobic properties, so in some cases it can replace waterproofing.
• Heaters of this group have a small mass, are easy to cut and install. Moreover, if necessary, it can be dismantled and used again in the same or another place.

• They isolate as much as possible from external influences: they do not let the wind through, they are resistant to critical temperatures, they significantly reduce the level of noise coming from outside, etc.
• Such insulation lasts a long time, while it does not rot and does not become moldy.
• It is much thinner than conventional insulation, but much more efficient and allows you to save energy costs up to 25-30 percent.
• The foil layer not only does not create problems for human health, but also becomes a barrier to the smallest particles of the base that can penetrate into the space of the room.

• Of the minuses of heaters with foil, we note the susceptibility of aluminum to gradual corrosion. The reflective layer begins to become cloudy over time, which leads to some weakening of its main reflective qualities.

• These materials are made on the basis of polyethylene foam using a special technology. The height of the insulation layer can be very different, ranging from very thin at 2 mm to relatively thick at 15 mm. As a rule, this is a rolled foil thermal insulation. Thicker materials can be supplied in standard size sheets.
• The thickness of the foiled foil layer is 10÷15 microns.
• The technical and operational characteristics of the insulation also depend on the type of source material:

• Inexpensive grades are made from ordinary polyethylene subjected to a repeated foaming process. The result is a closed porous gas-filled structure of the new material. These heaters have a significant drawback - this is a tendency to gradual shrinkage due to low resistance to mechanical stress.
• "Cross-linked" polyethylene (the so-called PPE-based heaters) has the best strength indicators. Cross-links at the molecular level provide resistance to mechanical stress.

Their density is slightly higher. Moreover, when the dynamic action stops, the material "tryes" to restore its original shape.

On a note

Some types of foiled polyethylene foam have an additional reinforcing layer of fiberglass mesh.

• A wide range of heat-insulating materials based on polyethylene foam is presented on the construction market. Among them, foil Penofol, Izolon, Folgoizol and others are most in demand.

• Insulation sheets are laid end-to-end and fixed to the surface, for example, using a construction stapler. In principle, you can use any other method. The main thing is that at the same time, the integrity of the foiling is not very affected. Then the butt joints are glued with foil tape.

Areas of use

• It is used as an additional or main thermal insulation layer when installing the floor, which also acts as a waterproofing layer. When laying the foil part, it should look up towards the top coat.

• It copes well with the thermal insulation of walls, as well as ceilings in rooms whose dimensions do not allow the use of thicker heaters, for example, on a narrow balcony (loggia). Fasten the material with a foil surface inside the room.
• It is used for insulation of roofing slopes as an independent material, and additional to others. In both cases, it is fixed with a reflective surface inside the attic room and a crate is stuffed onto it under the sheathing.
• With it, equip the thermal insulation of the bath. Simultaneously with the insulation of the bath from the inside (ceiling, walls), the issue of vapor and hydroisolation is also being solved - protecting the skin from waterlogging. For critically high temperatures, such as, say, in a steam room, such a material is not very suitable, since it is operated in a limited temperature range.

Foil mineral wool

It already has very high thermal insulation characteristics. Foiling, firstly, further increases the efficiency of insulation, and secondly, it is an additional way to protect the hygroscopic material from the penetration of excess moisture and steam, which could have an extremely negative impact on its performance.

The material goes on sale in the form of compressed rolls, sectional or individual plates, cylinders and semi-cylinders.

Application

• When thermally insulating the roof, the material is placed in the inter-rafter space tightly enough so that cold bridges do not form.
• The density of the foil is usually sufficient to be able to fasten the reflective layer to the staples. Joints must be glued with foil tape. This will help ensure the effect of hydro vapor barrier.

• The maximum operating temperature of this material is more than 300˚, so it is more than any other suitable for warming a bath. Some experts even consider this to be its main purpose. Insulating boards or mats are placed between the guides, laid with a step that is less than the width of the thermal insulation. It is obligatory to have an air gap of 20–25 mm, which is left between the thermal insulation layer and the wall and ceiling cladding.
• The heat resistance of mineral wool with foil makes it possible to use it for additional insulation of boilers, boilers and other similar devices.
• Collapsible cylindrical or semi-cylindrical thermal insulation materials made of foiled mineral wool are suitable for thermal insulation of pipelines.

Foam polystyrene foil

This is a durable thermoplastic obtained by fusing polystyrene granules with aluminum foil on one side. This is a strong material, resistant to significant mechanical stress and high humidity. It does not rot, biologically stable. Retains its characteristics in the temperature range from -180˚ to 180˚.

The material is often used when laying a warm floor. To facilitate this process, markings are applied to the plates at the factory. When laying the insulation, the foil layer reflects the heat flow upwards, warming up the finish coating.

The need for thermal insulation of engineering communications arises often. In order to avoid heat loss during the movement of hot water from the source of its heating to the end consumer, the pipeline should be insulated using, for example, a pipe insulation with foil as a material.

As practice shows, heat loss in the absence of insulation can reach 20 percent. In order to optimize the efficiency of the heating structure, it is necessary to insulate the line through which the coolant is transported. This work can be done independently, without involving specialists. At the same time, various materials are used, including liquid heaters, polyurethane foam (abbreviated PPU), mineral wool, penofol.

The need to insulate heating pipes

Due to the high cost of energy carriers, thermal energy must be used rationally, which means that only rooms that need it should be heated. If uninsulated pipes pass through a non-residential area, such as an attic or basement, then the heat is not being used for its intended purpose. This circumstance leads to a decrease in the performance of the heating system and an increase in the cost of purchasing fuel.

Insulation of the outer section of the heating main leads to a decrease in the likelihood of freezing of the coolant in the event of a sharp drop in temperature outside. True, freezing of the heat supply structure is unlikely, but traffic jams may appear.

For this reason, the insulation of the pipeline laid outside the building is a prerequisite for the operation of both internal and external sections of the heating system. Properly selected insulation thickness can protect the elements of the heating system from various kinds of damage, serious breakdowns and corrosive processes.

Selection of materials

There is a wide range of insulating materials for heat supply lines on sale. To make the right purchase, it is necessary to take into account the features of the room, its parameters and the technical conditions for operating the heating system.

The main factors influencing the choice of insulation:

• the location of the pipeline to be isolated;
• temperature of the coolant moving through the pipes;
• characteristics of the heating main;
• basic properties of materials intended for pipeline insulation.

When choosing, first of all, the following performance characteristics of heaters are taken into account:

• heat resistance;
• thermal conductivity;
• fire safety;
• moisture resistance;
• thickness;
• resistance to decay and exposure to microorganisms;
• installation cost.

When purchasing materials for pipe insulation, you need to remember that the lower their thermal conductivity, the higher the thermal insulation performance. The degree of moisture resistance is reflected in the quality of protection of metal pipelines from corrosive processes and the formation of condensate.

The fire resistance of heat insulators must comply with fire safety requirements for heated rooms. To calculate the thickness of the material used, special formulas are used.

A variety of heaters for pipelines

All types of heat-insulating materials used for heating pipes can perform their functions due to the presence of air in them, and their difference lies in the convenience of installation work.

The most easily performed method of insulation is considered to be thermal insulation, called the "shell". It is produced in the form of semi-cylinders. Installation is carried out by combining the halves through the grooves. As a result, the desired result is ensured when insulating pipes in the basement or attic.

The following pipeline heaters are most in demand: mineral or fiberglass wool, insulation for pipes with foil, polyethylene foam, polyurethane foam, expanded polystyrene, penoizol.

PPU insulation for heating systems

Material for insulation of pipes made of polyurethane foam is:

• sprayed;
• hard.

To apply PPU spraying, you will need special equipment and a 4-atmospheric compensator. The insulation is firmly connected to the surface of the pipes. But this material does not tolerate ultraviolet exposure, so it must be protected with winding or aluminum foil. When applying spraying, it is necessary to use protective clothing.

The rigid type of PPU insulation is durable and at the same time light, has a low coefficient of thermal conductivity and is used for individual circuits. Of its advantages, it should be noted that it has increased resistance to moisture. The material is environmentally friendly and completely non-toxic. It is mounted around the pipeline in the same way as the "shell".

Foil insulators for heating systems

If you need to make a decision regarding the material, the best choice would be to use a foil pipe insulation. Thermal insulation is considered effective if it allows not only to retain heat, but also to reflect it. In this case, it is preferable to use materials with aluminum foil.

In addition, the foil insulation for heating pipes does not let in the cold coming from the outside and demonstrates excellent hydro and vapor barrier. In the process of its manufacture, the main heat-insulating material is applied to the foil layer - it can be polystyrene foam, polyethylene foam or mineral wool.

This type of thermal insulation of different thicknesses for pipelines passing through living quarters, a basement or an attic is produced in the form of a "shell", slabs, rolls, mats, canvases.

The use of foil thermal insulation for pipes

According to experts, the simplest method of thermal insulation of pipelines in the basement is the use of mineral wool, which is covered with a layer of foil, while the thickness of the wool reaches 50 millimeters, and the reflective layer is 10-30 microns.

Before proceeding with the insulation of pipes in the attic or basement, you need to study the operating conditions of the materials. For example, foil with foamed polyethylene is brittle and subject to deformation under external influences. Strength indicators can be improved if thermal insulation with pipe foil and foam is preferred.

In turn, basalt insulation has many characteristics in common with mineral wool, but it is heavier because it has a higher density.

It is convenient to install self-adhesive insulation. If the foil is damaged, use aluminum tape. Lavsan film with foil and polyethylene foam do not reflect infrared radiation, so such material must have a significant thickness of the foil layer.

The main nuances of using heat insulators

Before buying rolled insulation for heat supply pipes, you need to make sure that its performance allows you to use this material in an attic or basement.

When the insulation is rigid and made in the shape of a semicircle, it can be used for pipe products of a certain diameter. Between the wall and aluminum foil, you need to leave a distance of 25 millimeters.

The cost of a heat insulator is affected by the thickness of the reflective layer and the material from which its base is made. There is a significant difference between aluminum foil and aluminum sputtering. The latter option makes the functioning of the heat insulator less effective with little reflectivity.

It is not at all necessary to buy industrial foil pipe insulation. You can independently wrap the layer of thermal insulation laid on the pipe with foil if the pipeline is laid in the attic or basement. Such material is produced in rolls or in the form of hollow tubes.

The foil is placed face up. Between the foil layer and the pipeline, a gap of 10 -20 millimeters must be left.

Independent installation of thermal insulation

Work on the insulation of heating pipes using heat-insulating polystyrene foam shell is performed as follows:

1. Halves of the material are put on the pipe and their displacement relative to each other is ensured - it is required for an overlap of 10–20 centimeters in size.
2. Semi-cylinders should be fastened in advance with adhesive tape. If you need to apply a surface protective layer, it is attached at the very end.
3. In order for the shell to more reliably adjoin the pipeline, the joints must be glued with adhesive tape.
4. When it is necessary to isolate heating pipes at the turns of the main, shaped types of shells are used.

In many ways, the choice of materials for insulating the elements of the heating system depends on the operating conditions of the heating main and its structural device. The work on thermal insulation is simple and, if desired, any home master can perform it.

Pipe insulation performs very important functions. Without it, we would have to lay pipes exclusively in rooms with a normal temperature level, or deep underground.

Otherwise, the cavity of the pipes cannot be protected from freezing in the cold season, and hence from paralysis of the entire water supply system.

However, now the thermal insulation needed to protect pipes is in abundance on the market. We will pay attention to its interesting subspecies - foil insulation for pipes. What are its features and advantages?

Features and purpose of heaters

As we noted above, pipe insulation is used almost everywhere. Its main task is to protect pipes from freezing in the winter. If the pipes are not treated properly, then at best the water supply system will partially freeze. At worst, it is completely blocked.

Thawing water supply systems, and even in winter, is an expensive pleasure. Not to mention the fact that in such situations the risk of damage or breakthrough of one of the sections increases significantly.

Also, the insulation protects the surface of the pipes from heat loss, which means it increases the overall efficiency of the heating system.

Foil as insulation

Foil insulation is often used in construction. However, don't be fooled into thinking that foil is the standard material for thermal insulation.

On the contrary, the foil performs those functions that ordinary heaters, such as mineral wool or polystyrene, are simply unable to cope with.

It's all about the special properties of the foil. You probably already know about the types of thermal radiation. If not, we will now briefly recall.

There are three types of radiation:

• convection;
• heat transfer due to thermal conductivity;
• ultraviolet or thermal.

The first option does not interest us, it is limited by special means. The second option is the main item of heat consumption. It consists in the fact that any structure or equipment quickly gains or releases heat from the atmosphere.

To reduce the rate of interaction with the thermal environment, standard thermal insulation is used. Its thermal conductivity is too low for heat transfer, which means that a structure protected by such a casing will not encounter low-temperature zones at all.

But the third type of radiation is not able to level the usual insulation. For such tasks, a material is needed that is capable of reflecting heat waves that are not visible to the eye. Just for such purposes, foil is used.

It reflects heat radiation, preventing unnecessary energy consumption. In this case, for effective interaction, it is sufficient to have a foil layer with a thickness of only 1 mm, or even less.

The need for combination

So why not use foil alone, you might ask. Surely you can do there, if not for one of its serious shortcomings. The foil is very fragile. Even building samples with a fairly serious thickness can be damaged with bare hands.

Yes, and it is really difficult to mount such a delicate material as thermal insulation.

Manufacturers immediately understood the essence of the problem, and offered an elegant, but at the same time extremely effective solution. They began to produce foil insulation. That is, combine standard materials for insulation with the foil itself.

In terms of effectiveness, the material received exceeded all our expectations. A man managed to create a heater that is able to cope with two main articles of heat loss at once.

Losses due to different levels of thermal conductivity are eliminated by the base thermal insulation material (mineral wool, polystyrene, etc.). And the foil shell reflects heat radiation.

At the same time, the risk of destruction of the foil no longer threatens us, and if the shell breaks somewhere, then it's okay. It is specially glued to the body of the insulation so that serious damage to even a large area does not affect the overall protection of the structure.

It is quite obvious that similar schemes began to be used for pipe insulation with the same enthusiasm. Moreover, foil thermal insulation for pipes has become the most popular solution in recent years.

Types of foil insulation

Foil thermal insulation is combined with several materials at once. You need to choose one or another sample carefully, weighing all their properties, and also taking into account the features of a particular insulation.

There is foil thermal insulation:

1. Mineral wool.
2. Styrofoam.
3. With polyethylene foam.
4. With foam base.

We have listed only the main samples. There are also less popular, specialized options, so to speak, but they are either too expensive or used in a narrow direction.

Mineral wool insulation

In part, the foil just forms this very protection, but only in part. Upon contact with high temperatures, the foam will quickly catch fire, becoming essentially one of the sources of fire.

As for the design of the insulation, the foam is produced in the same way as the minuvata - in specially cast half-forms, around which foil is glued.

Polyethylene foam foil

Foamed polyethylene with foil is a more modern insulation. It cannot boast the same thermal conductivity as mineral wool, or the cheapness of polystyrene, but it is light and easy to handle.

Foamed polyethylene is probably the easiest to install. After all, the blanks are very plastic, made in the form of ready-made shells for pipes, cut along the axis.

You just need to put the insulation on the pipe like a peel, and then blind the seams with special glue for polyethylene. It is sold at any hardware store.

Foamed polyethylene has a soft structure, does not corrode, does not react to moisture. It is produced in blanks with wall thicknesses from 1 cm to 5 cm. There are also larger samples, but there is no use for them in domestic construction.

Foil polyethylene is so easy to use that it is even placed on those systems that, by and large, do not need insulation. In this case, thermal insulation performs protective and aesthetic functions.

Features of pipe insulation (video)

The use of penofol

The last sample considered is . Penofol is a material that consists of two components: foil and a thin layer of hardened foam. It cannot be called a traditional solution.

The thickness of the material rarely exceeds a few millimeters. Penofol cannot boast of high thermal insulation properties. In fact, it is just a protective wrapper with a reflective effect. However, for basic protection of pipes, it is sometimes used.

Penofol is very cheap. A square meter sells for $1 or even less. It is also easy to cut and glue. That is, a pipe of any diameter can be quickly wrapped as you need.

The quality of the result, of course, cannot be compared with the use of the same polystyrene or foamed polyethylene, but if there are no other options, then this one will be a joy.

Moreover, you can work with it with your own hands, practically without spending additional funds.
