Foil pipe insulation. Application of insulation with foil: we become familiar with the types of insulation with foil and their name. Important points about using insulation

Infrared radiation passes through most insulation without hindrance. Thermal insulation for pipes with foil is highly reflective and retains heat much more effectively than materials without a protective layer.

According to average statistics, a building loses from 40% to 70% of thermal energy in winter. Heat loss occurs for three reasons: due to the high thermal conductivity of the pipe material, due to convection and due to infrared radiation. Heat transfer can be stopped by reflection.

You can purchase foil insulation for pipes, or you can wrap the insulating layer with foil yourself. This insulation is sold either in rolls or in the form of hollow tubes. The foil is laid front side out. It is important to ensure a gap of 1-2 cm between the foil and the pipeline. The disadvantages of foil are its fragility and susceptibility to aggressive substances. The top protective layer transmits about 10% of the energy.

Choice of insulation

Insulation (polyurethane foam, fiberglass, polystyrene foam, mineral wool, foamed polyethylene) can be covered with a metallized film or aluminum foil on one or both sides.

Mineral wool covered with a layer of foil is the simplest option. The thickness of the reflective surface is from 10 to 30 microns, the thickness of the wool is up to 5 cm. Foil with foam has increased strength. Foil with polyethylene foam is more fragile and can be deformed under the influence of external forces. The advantage of such insulation is vapor permeability. Basalt thermal insulation is similar to mineral wool, but heavier, as it has a higher density. Thermal insulation with a self-adhesive base provides undeniable ease of use. If the foil is damaged in some place, you can use aluminum tape. It will also be needed when joining parts of the material.

Foil insulation. Aluminum surface reflects heat waves using the mirror principle

Mylar film and polyethylene foam with foil can transmit infrared radiation. Therefore, you should choose a film with a thick foil layer. Poriflex NPE-LF, penofol 2000, BestIzol, Ecofol are the most popular brands of foil pipe insulation. The air layer inside the polyethylene foam and the top polished layer allow the materials to be used not only in industry, but also in private homes. The thickness of such insulation usually does not exceed 1 cm. The quality guarantee only applies to materials that have been certified.

Why foil insulation - right choice?

  • The material can be used at temperatures environment-60°..+150°.
  • Vapor permeability: 0.001% (foil almost does not allow steam to pass through). Water absorption: 0.74% per day.
  • Easy to install, low cost, environmentally friendly, good waterproofing properties, ability to absorb noise and dampen vibrations in ventilation systems.
  • Creating a “thermos” effect.
  • Easy to install and environmentally friendly material.

Disadvantage of foil: high thermal conductivity. That is why it is not used separately, but together with traditional insulation.

Heating and sewerage

Rockwool cylinders – The best decision for heating pipes, ventilation ducts, air conditioners and sewer pipes. This flexible foil pipe insulation is resistant to chemical irritants and is easy to install. Covered with a protective layer, the casings are strong and durable.

Installation method:

  1. First they cut required length segments. The segments are joined closely to each other.
  2. Then 2 fasteners are installed on each segment with a distance of 500 mm between them.
  3. For vertical sections, retaining rings are used that prevent the cylinders from slipping over time.
  4. For curved pipes, the cylinder is trimmed by fitting the hole along the pipe.

Technical thermal insulation – hollow cylinders made of stone wool and covered with a layer of aluminum foil. It is intended for insulation of heating networks and industrial pipelines. They have a longitudinal cut for the easiest possible installation.

Seams between components glued with aluminum tape

Chimney

Insulation of the chimney is necessary to create good draft. The heat barrier prevents the formation of condensation, which means it protects chimney from destruction.

Learn how to make a tube-cover for an iron chimney out of foil. You will need rockwool (wire-stitched Rockwool mats will work), foil and hardware.

  1. Unwind the roll and use pruning shears to separate the desired section.
  2. Using fasteners and wire, wrap the pipe with insulation.
  3. Wrap everything on top with aluminum foil and secure with zip ties. Instead of mineral wool, you can use any other non-flammable material.

It is enough to put the casing on the pipe and fix it - reliable protection heat guaranteed

Energyflex pipe insulation

Has its own strengths and weak sides. The advantages include strength, moisture resistance, and immunity to temperature changes. The material does not cause difficulties during installation and is light in weight. The layer thickness can be from 9 to 13 mm, length - up to two meters. Suitable for pipelines with diameters from 18 to 160 mm. The flexible material can be laid in areas with complex geometries.

Energoflex does not require additional wrapping with roofing felt. The disadvantages are the high cost and the impossibility of installing it where the temperature of the pipeline working environment exceeds 100°.

Important points:

  • If you are purchasing roll insulation, make sure that it is intended specifically for pipes before purchasing.
  • The rigid material in the form of semicircles is sized to fit onto a pipe of a specific diameter.
  • A distance of 2.5 cm must be maintained between the wall and aluminum foil.
  • The price of insulation is affected by both the thickness of the reflective layer and the base material.
  • There is a significant difference between aluminum plating and aluminum foil. In the first case, the heat insulator will work less efficiently, its reflectivity is low.

When preparing to carry out work on thermal insulation of a house, the question of choice arises optimal insulation. For an ignorant person to decide on a wide variety of heat insulating materials not easy. That’s why, when planning a purchase, you need to prepare in advance: clarify the features of a particular insulation and the scope of its use, specifications etc.

A comfortable temperature in the house is often achieved using porous or fibrous materials with low thermal conductivity. However, insulation materials that work on a different principle - reflectivity - have become increasingly popular. mirror surface. This is exactly how foil thermal insulation works, which is considered the most effective today.

What is thermal insulation with foil

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

Types of insulation

Foil thermal insulation has a variety of release 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.

  • Type of base layer.
  • foamed polyethylene,
  • mineral or basalt wool;
  • expanded polystyrene.
  • Foil insulation technology. Aluminum foil for thermal insulation can be glued or sprayed, perforated or not.
  • Number of reflective layers. On some types of thermal insulation, foil can be applied on one or both sides, on others there is an adhesive layer, that is, in addition, such thermal insulation is reflective, it can be laid directly on the surface without. These insulation materials are marked A, B and C, respectively.

On a note

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

  • Purpose. Thermal insulation materials coated with foil are used both as primary and additional thermal insulation.

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

  • base material;
  • thickness of aluminum foil;
  • height of the thermal insulation layer;
  • number of reflective screens.

Advantages and disadvantages

  • Foil has 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 the heat inside, 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.
  • Insulation materials of this group are lightweight and 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 allow wind to pass through, are resistant to critical temperatures, significantly reduce the level of noise coming from outside, etc.
  • Such insulation lasts a long time, and does not rot or become moldy.
  • It is much thinner than conventional insulation, but is much more effective and allows you to save energy costs by 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 room.
  • Among the disadvantages of insulation with foil, we note the susceptibility of aluminum to gradual corrosion. The reflective layer begins to become cloudy over time, which leads to a slight weakening of its basic 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 2 mm to relatively thick 15 mm. As a rule, this is rolled foil thermal insulation. Thicker materials can be supplied in sheets of standard size.
  • The thickness of the foil layer is 10÷15 microns.
  • The technical and operational characteristics of the insulation also depend on the type of source material:
  • Inexpensive brands are made from ordinary polyethylene, subjected to multiple foaming processes. The result is a closed porous gas-filled structure of the new material. These insulation materials have a significant drawback - they are prone to gradual shrinkage due to their low resistance to mechanical loads.
  • “Cross-linked” polyethylene (as insulation based on PPE is called) 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 impact stops, the material “tries” to restore its original shape.

On a note

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

  • The construction market offers a wide range of thermal insulation materials based on foamed polyethylene. Among them, the most popular are foil Penofol, Izolon, Folgoizol and others.

  • The 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 in this case the integrity of the foil is not greatly damaged. Then the joining seams are taped with foil tape.

Areas of use

  • It is used as an additional or main thermal insulation layer when installing a floor, which also acts as a waterproofing layer. When laying, the foil part should face upward, towards the finishing coating.

  • It copes well with thermal insulation of walls, as well as ceilings in rooms whose dimensions do not allow the use of thicker insulation, for example, on a narrow balcony (loggia). Fasten the material with a foil surface inside the room.
  • It is used for insulation of roof slopes as independent material, and additional to others. In both cases, it is fixed with a reflective surface inside the attic room and a sheathing is placed on it under the sheathing.
  • With its help, they equip the thermal insulation of the bath. Simultaneously with the insulation of the bathhouse from the inside (ceiling, walls), the issue of vapor and waterproofing is also being resolved - protecting the casing from waterlogging. For critical high temperatures, as, say, in a steam room, such material is not very suitable, since it is used in a limited temperature range.

Foil mineral wool

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

The material is sold in the form of compressed rolls, sectional or individual slabs, cylinders and half-cylinders.

Application

  • When thermally insulating the roof, the material is placed in the space between the rafters tightly enough to prevent the formation of cold bridges.
  • The density of the foil, as a rule, is sufficient to allow fastening to the brackets using the reflective layer. The joints must be taped with foil tape. This will help ensure a water vapor barrier effect.

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

Foiled polystyrene foam

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

The material is often used when laying heated floors. To facilitate this process, markings are applied to the slabs at the factory. When laying insulation, a layer of foil reflects the heat flow upward, warming up the finish coating.

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

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 heating pipes properly insulated?

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

Selection and installation of pipe thermal insulation 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 heating or water supply networks, and trust the installation of the material only to professionals.

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

For thermal insulation of pipelines, you should only choose quality materials. It is also necessary to take 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), they are used different types thermal insulation of pipes.

For indoor use, it is optimal to use ROCKWOOL thermal insulation cylinders. Products from a well-known manufacturer have high quality and unique properties. High requirements for products technical insulation, allow Rockwool cylinders to be No. 1 today. They are made from mineral wool on a synthetic binder 1 meter long. 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 an additional coating of aluminum foil.

For external use, Rockwool mineral wool cylinders can also be used, but with subsequent covering in the form of protective shells. They protect products from 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 polyurethane foam shells or polystyrene foam shells. For underground applications, this is the most common insulation option. In any case, it is recommended to carry out all necessary measures to protect pipes strictly according to the project, which specifies certain materials necessary for insulation.

Thermal insulation of heating pipes is reliable protection of pipes. The efficiency of heating mains depends on the thermal insulation material, because without it heat losses occur, especially in winter time. All this is reflected in the wallets of our citizens.

Reasonable prices for pipeline insulation

Today you can buy thermal insulation for pipes at different price. When choosing a particular material, the buyer is often interested in what determines the price of pipeline insulation. The answer to the question is simple.

The cost of the material is affected by the following:

  • country of origin - imports are always more expensive compared to domestic goods, although they are of the same quality;
  • density of the material - the denser, the more expensive;
  • thermal insulation thickness;
  • the ratio “pipeline insulation - price” completely depends on the construction material;
  • Wholesale purchases are always cheaper than retail sales.

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

The need for thermal insulation engineering communications occurs frequently. So that when moving hot water there was no heat loss from the source of its heating to the end consumer, the pipeline should be insulated using, for example, 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 efficiency heating structure it is necessary to insulate the line through which the coolant is transported. This work can be done independently, without involving specialists. In this case they use various materials, among which liquid insulation, polyurethane foam (abbreviated as PPU), mineral wool, penofol.

The need to insulate heating pipes

Due to the high cost of energy resources, thermal energy must be used rationally, which means that only the rooms that require it should be heated. If uninsulated pipes pass through a non-residential area, such as an attic or basement, then heat is wasted for other purposes. This circumstance leads to a decrease in productivity heating system and increased costs for purchasing fuel.


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

For this reason, insulation of a pipeline laid outside a building is a prerequisite for the operation of both internal and external sections of the heating system. Correctly selected insulation thickness can ensure protection of heating network elements from various types 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 do the right purchase, it is necessary to take into account the characteristics of the room, its parameters and technical operating conditions of the heating system.

The main factors influencing the choice of insulation:

  • location of the pipeline that needs to be insulated;
  • 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 take into account the following performance characteristics of insulation:

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


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 corrosion processes and condensation formation.

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

Variety of insulation for pipelines

All types of thermal insulation materials used for heating pipes can perform their functions due to the presence of air in them, and their difference lies in the ease of installation work.


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

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

PPU insulation for heating systems

The material for insulating polyurethane foam pipes is:

  • sprayable;
  • tough.


To apply polyurethane foam 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 radiation well, so it must be protected with winding or aluminum foil. When applying spraying it is necessary to use special clothing.

The rigid type of polyurethane foam insulation is durable and at the same time light, has a low thermal conductivity coefficient and is used for individual circuits. Among 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 a “shell”.

Foil insulators for heating systems

If necessary, make a decision regarding the material best choice Foil pipe insulation will be used. 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, foil insulation for heating pipes does not allow cold coming from outside to pass through and demonstrates excellent hydro- and vapor barrier. During its manufacturing process, the main thermal insulation material– it can be polystyrene foam, polyethylene foam or mineral wool.

This type of thermal insulation of different thicknesses for pipelines passing through living quarters, basement or attic is produced in the form of “shells”, slabs, rolls, mats, and sheets.

Application of foil thermal insulation for pipes

According to experts, the most in a simple way thermal insulation of pipelines in the basement is considered to be 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 - 10-30 microns.

Before you begin insulating pipes in the attic or basement, you need to study the operating conditions of the materials. For example, foil with polyethylene foam is fragile and is subject to deformation under external influences. Strength indicators can be increased if you prefer thermal insulation with foil for pipes and foam plastic.


In turn, basalt insulation has many general characteristics with mineral wool, but it is heavier because it has greater density.

It is convenient to install self-adhesive insulation. If the foil is damaged, use aluminum tape. Mylar 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 thermal insulators

Before purchasing rolled insulation for heating pipes, you need to make sure that its performance characteristics allow the use of 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. A distance of 25 millimeters should be left between the wall and aluminum foil.


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 coating. The latter option makes the functioning of the heat insulator less effective with low reflectivity.

It is not at all necessary to buy foil pipe insulation industrial production. 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. This material is produced in rolls or in the form of hollow tubes.

The foil is laid face up. A gap of 10-20 millimeters must be left between the foil layer and the pipeline.

Self-installation of thermal insulation

Work on insulating heating pipes using thermal insulating polystyrene foam shells is carried out as follows:

  1. The halves of the material are put on the pipe and their displacement relative to each other is ensured - this is required for an overlap measuring 10–20 centimeters.
  2. The half-cylinders should be secured in advance with tape. If a surface protective layer needs to be applied, it is attached at the very end.
  3. In order for the shell to more securely adhere to the pipeline, the joints must be taped with tape.
  4. When it is necessary to insulate heating pipes at turns in the main, shaped types of shells are used.

In many ways, the choice of materials for insulating heating system elements depends on the operating conditions of the heating main and its structural design. Thermal insulation work is simple and can be done by any home craftsman if desired.
