It is important to insulate pipes in the basement of a private house in order to exclude the appearance of condensation on communications. If the basement of the house is cold or in the house long time do not use water, then a layer of insulation will protect the pipe from possible freezing. Consider the ways of insulation water pipes in the basement of an apartment building and a one-story building with various materials. At the end of the article, we will show a video from a pipe insulation manufacturer.
For insulation, they used to use any available materials - old blankets, foam rubber, synthetic winterizer from old jackets, etc. But today, pipe heaters are presented on the construction market in a wide range: from expanded polystyrene shells, polyurethane foam and mineral wool to simple roll insulation made of foamed foam and isolone. To begin with, we will analyze the advantage of pipe insulation, the better to protect the pipes in the basement from freezing.
Do I need to insulate pipes in the basement of the house
You should think about the insulation of pipes from the well to the house and in the basement before the onset of cold weather. Insulation of communications in the ground is a very laborious process, it is better to do it immediately when laying pipes, since the most problematic sections of the water supply system with cold water are on the street. Thermal insulation of pipes in the basement apartment building reduces the risk of condensation and moisture on the surface of cold water pipes.
The main requirements for materials for underground plumbing are low price, ease of installation, the longest possible service during humid environment and low thermal conductivity. When choosing thermal insulation, it is necessary to take into account the fire safety and incombustibility of the material, the duration of the service life and the possibility of reuse if repair is necessary. Consider further, the better to insulate the pipes in the basement of the house with your own hands.
How to insulate pipes in the basement with your own hands
Mineral wool and glass wool in the form of cylinders make it easy to handle polyurethane foam pipes. The pluses of mineral wool include low thermal conductivity, however, additional waterproofing of the insulation with the help of roll materials, which complicates the work. Upper layer may have a metallized foil layer, but the cost of this insulation can be quite high.
Expanded polystyrene and polyurethane foam are not afraid of high humidity, so they can be used without additional waterproofing coating. The shell made of extruded polystyrene foam (expanded polystyrene) can be reused, and the ease of installation makes its use very convenient and easy. Shells of various diameters are produced, the material is fixed on the pipes using plastic clamps or simple tape.
Foamed polyethylene does not decompose in a humid environment, has high thermal insulation characteristics and elasticity. Penofol and Izolon are produced in the form of a hollow tube from 1 to 1.5 meters long with a cut. You can also use roll materials made of foamed polyethylene, which are cut into strips and wound on metal or polypropylene pipes in a spiral. Insulation is attached with adhesive tape.
How to insulate pipes in the basement with your own hands
Before starting work, water supply or heating pipes must be prepared. First of all, all treated surfaces are first cleaned of dust and dirt. Metal pipes should be treated with a primer or mastic to protect against corrosion. You can insulate the heating pipes in the basement of an apartment building with mineral wool with your own hands - this will reduce heat loss, and in the tap and in the heating radiators, the water will become much hotter.
Insulation of pipes in the basement of the house with mineral wool
The main problem in the basement is small space and poor lighting. It's easy to work with mineral wool pipe shells. Heating or water supply pipes are simply wrapped with insulation, which is fixed with tape and clamps. If the remnants of roll insulation are used for insulation, then this is a more laborious process. To do this, you need to cut the insulation into strips. suitable size and wind them around the water pipe.
The basalt insulation is fixed with a nylon rope. The rope is tied on one side of the pipe and the insulation on the pipe is wound in a spiral to the very end. On top of the insulation, it is necessary to make protection against mechanical damage and moisture. To do this, cut the roofing material or foil-clad penofol into thin strips with the desired length and wrap over the insulation. When working, use individual means protection - gloves and a respirator.

Insulation of a water supply system with a polyurethane foam shell
Insulation of pipes with shells is the easiest way to protect communications in the basement of a house from freezing. Insulation for pipes made of polystyrene or polyurethane foam (polyurethane foam) is produced with different diameters, so you can easily find the right size for yourself. The characteristics of extruded polystyrene foam and polyurethane foam are almost the same, so when buying, pay attention mainly to cost. The installation of the shell is easy.
To install the insulation, take two halves of the shell and connect them on the pipe, securing them with tape on top. Lay the following insulation elements overlapping the previous ones. There are special elements for bends and turns, so you don't need to cut anything extra from the tubes. All operations are repeated until all pipes in the basement are completely protected by insulation from heat loss and possible freezing.
Insulation of the water supply system in the basement with isolon
Polyethylene foam insulation in the form of hollow tubes is a more common method of thermal insulation for all kinds of communications in basements apartment buildings... The material can be used when installing pipes, and after. In the second case, it is necessary to make a lateral cut on the foamed polyethylene tube and wrap the pipe along with the turns and bends. The material is attached to the pipe using clamps or tape.
The advantages of isolon and penofol are vapor impermeability, that is, additional waterproofing is not required. Instead of buying insulation, you can use trim roll insulation made of foamed polyethylene. This option will be less aesthetic, but no additional costs are required. The insulation is simply cut into narrow strips and wrapped around the pipe (you can wrap several pipes at once) in a spiral.

Insulating the water pipes in the basement means creating a comfortable microclimate and reducing the cost of the heating system. Such works are important both for private houses and for multi-apartment buildings. Certain requirements apply to the pipeline insulation process. This applies to any systems: plumbing, heating and sewerage.
V last years polypropylene structures in the basements of houses have become popular. Do I need to insulate them? If during the construction process it was not insulated strip foundation, it is required. If a private building is used only in summer and is not heated in winter, pipe insulation will not allow the system to freeze and fail.
Requirements for insulation materials
To insulate pipes in the basement of a private house, they are used various materials... Regardless of their type and composition, they must correspond to important indicators:
- be durable;
- resistant to moisture;
- fireproof;
- easy to install;
- resistant to temperature extremes.
How to insulate the pipeline in the basement
The better to insulate the water pipes in the basement, because the choice of materials is great. The first step is to choose a heater that meets the above requirements.
Mineral wool and glass wool
These insulators are best used for metal-plastic structures. Fiberglass has low thermal conductivity and high temperature resistance. But it does not tolerate moisture. Therefore, you will have to spend extra money on moisture insulation. Such insulation is used only for buildings that are heated all year round.
Minvata is dangerous for human skin and mucous membranes. It is recommended to work with it with gloves and a respirator. The material must be wound around the pipeline and secured with a strong rope. Wrap the entire length of the pipe and secure at the end. It is recommended to apply foil or roofing felt on top of the mineral wool.
PPU and expanded polystyrene
Such insulators are resistant to moisture and mechanical stress. They can be used several times if repair and analysis of the structure is required. To insulate the heating pipes in the basement with expanded polystyrene, you need to wind it around the pipe and fasten it with tape around the entire circumference. Such insulation has the properties of a thermos. It is highly resistant to environmental influences and perfectly retains heat around the pipe.
Foamed polyethylene
The insulator is easy to install. Quickly attaches to pipes. Using clamps or foil tape. Perfectly protects heating structures in private houses. Can be used many times.
The process of warming the plumbing in the basement
You don't need to insulate the water pipe in the basement yourself. professional tools and skills. After selecting a suitable insulator, you need to arm yourself with clamps, tape or nylon wire.
- Measure outside diameter and the length of the pipeline. Cut the material according to the parameters. Sometimes you need to wrap sewer pipes repeatedly. This should be taken into account when "cutting" the insulator.
- Wrap the heating structure and immediately fix the insulation. Wrap tape or rope tightly. It is easier to work if the materials are cut to length in small pieces.
During severe frosts, problems arise with the freezing of water in the water pipes of the basements of apartment buildings. Rupture can occur with both plastic and metal.
Today we will try to reveal as much as possible the principles associated with the insulation of pipes in an apartment building.
Things to consider when performing thermal insulation
Before proceeding with the insulation of a structure located in the basement of an apartment building, you should learn the basic requirements in order to get the expected result and avoid numerous problems.
- Maximum service life.
- Self-extinguishing ability.
- The presence of water repellency.
- Ease of installation.
- Low cost.
- Environmental friendliness.
- Low thermal conductivity.
Thermal insulation in an apartment building
What materials are preferable?
Today, the variety of materials with which you can quickly and easily insulate the water supply in the basement is impressive.
Among the effective and most popular are the following:
1. Mineral wool
Elements made on the basis of mineral wool will cope with temperature extremes. With its help, you can insulate not only pipes in the basement of an apartment building, but also those that are outside or in the ground. What the mineral wool looks like can be viewed below in the photo.
2. Polyurethane foam
Ideal for basement and attic water insulation. In fact, it is the outer shell of the aqueduct. This design minimizes heat losses and adds strength. This heat insulator is not afraid of chemical influences, does not rot. But it has one drawback - high cost.
3. Expanded polystyrene
This material is characterized by high level rigidity. A polystyrene foam insulation is sold in the form of a part of a pipe that has protrusions for fastening.
4. Foamed polyethylene
This heat insulator is best suited for internal insulation heating systems.
5. Styrofoam
Polyfoam is good for insulating heating and water supply systems on the basement and basement floors. Has a low level of moisture absorption. Also, the foam is very durable, it can be used for more than two decades.
6. Foamed rubber
The heat insulator has a number of advantages. It is elastic, resistant to temperatures and not afraid of fire. Due to the fact that it is resistant to fire, it is suitable for thermal insulation of external piping.
7. Liquid heat insulator
High quality material that can compete with others on an equal footing. For example, one coat of paint can replace a 5 cm layer of polyurethane. In addition to insulating properties, liquid thermal insulation is able to protect metal from corrosion and betrays good appearance pipes. But it is not used for thermal insulation of plastic pipes.
Regardless of the material you choose, the main thing is that the thermal insulation is effective, and on cold days there are no problems with rupture or other damage. More detailed instructions on the installation of one or another heat insulator, you can watch the video on the Internet. It is worth noting that working with heaters is not difficult, you can easily do it yourself.
Why is pipe insulation necessary? Perhaps this main question before carrying out the required series of works. Having answered it, it will be easier to decide in the future and with insulating material, and with sites that necessarily require such an addition.
Pipe insulation material
Most of the pipes that conduct communications to apartments or private houses are located on the street, underground or in technical rooms. For example, in the basement, in the attic, etc. It should be noted right away that these premises are not residential, which means they do not have sufficient conditions. First of all, this applies to the microclimate inside. If, for example, the relative dryness of the room, a certain comfortable temperature range, is constantly maintained in an apartment, then outside the home there is usually a completely opposite environment. It is often quite aggressive, especially in our climate. This applies to both temperature drops and their extreme values. And, of course, such a situation is not in favor of pipelines, which are obliged to work continuously, to perform their functions in any situation.
Example of pipe insulation
In particular, heating pipes require insulation. Most of these pipes in the apartment may have been replaced with polypropylene pipes, which are more resistant to drops and moisture, but outdoor products are usually made of metal. Given the fact that there is a certain environment inside the pipe, which can be completely opposite to the environment outside, their insulation or insulation is the only way to extend the service life and avoid the failure of the entire heating system.
Pipes in the attic and basement
Heating products that are in the attic are most often faced with the lowest temperatures. As a result, due to the high plus inside the pipe and the critical minus outside, microcracks form in the metal, which lead to the gradual destruction of the material.
Modern pipe insulation technologies
In the basement, the temperatures are more comfortable, but always high humidity... It is also known from the chemistry course that moisture for unprotected metal is corrosion and rust, which gradually "eat up" the material, rendering it unusable.
Pipes in an apartment should also be insulated if, for example, they are close to the coldest wall. This will save you from temperature conflicts, and most importantly, heat loss, which is very important indoors for a comfortable stay.
Insulation materials
On modern market pipe accessories can be found all kinds of isolation, which have their own characteristics and areas of application. Most of them work well for heating pipes.
Foamed polyethylene - these are tubes of different diameters, each has a special incision for easy attachment. The material insulates in all directions. Also, to improve the quality of protection, the material is foiled.
- Foamed rubber. This is an almost identical type of insulation. The only one characteristic feature material is its fire safety. Namely, when the surrounding objects ignite, the material does not support combustion and is extinguished. The rubber is also foiled, which significantly reduces heat loss.
- Liquid insulation or thermal paint. This type of protection is the simplest, it is an innovation and consists in applying a special layer of a protective substance (paint) to the pipes. The main advantage of this type is the ability to protect even the most hard-to-reach places... If you go back to the basement and the attic, then in this situation, this material will be a good choice.
Correct pipe insulation
Regardless of the location of the products, all pipes are insulated in separate sections. It should not be mounted with an overlap, but the joints should be fixed with special tape to avoid loss through the seams. In the case of the formation of spans of insulation of more than one and a half meters, it should be rigidly fastened with tape, tightly tightening at the same time. Also, at the beginning and at the end of the insulation segment, it must be fixed first of all in order to avoid shifts.
Outdoor insulation
- Low thermal conductivity.
- Long service life.
- Ease of installation.

Details about the thermal insulation of heating pipes
Thermal insulation heating pipeline extremely important as it prevents heat loss. You should resort to it if the heating pipes pass along the street, underground, in a concrete floor screed, basement or in the attic.
As a rule, such conditions provoke significant heat loss. After all, the contact of cold air with heating pipes cools the coolant itself. Accordingly, the radiators will heat up less. In this case, each owner of a private house tries to increase the temperature level in the room.
Indoor thermal insulation
As already mentioned, the thermal insulation of the pipeline is extremely important in those places where there is a possibility of exposure to cold air.
Thermal insulation of heating pipes in an apartment is quite rare, since the pipeline passes through the rooms that are to be heated. That is, the fact that the pipe itself gives off heat to the air can also be called a part of the heating process.
However, thermal insulation is needed if the heating pipes are installed in concrete screed floor. Indeed, in this case, part of the thermal energy is simply given up to cold concrete. That is, the quality of heating suffers.
An example of using Energoflex for arranging a warm floor is shown
In addition, the piping in the screed creates a kind of warm floor where it is not needed. To insulate pipes installed in the floor, you should use sufficiently dense foam materials, for example, energy flex.
Similar materials are perfect for thermal insulation of the pipeline laid in the attic and in basement... For ease of installation, it is better to use tubular materials.
They are a soft flexible tube with a longitudinal cut. She just puts on heating pipe and is fixed with special clamps or ordinary tape. Such insulation will last for a long time, provided that it is installed correctly.
Important: when carrying out thermal insulation, you should be careful: the pipe must be tightly covered with insulating material. The presence of gaps - possible way for heat loss. In order for the work to be of the highest quality, in some cases a plastic corrugation is put on top of the heating pipe.
In addition to preventing heat loss, thermal insulation is important enough to maintain the integrity of the pipeline.
In particular, thanks to the protective layer, they are not exposed to moisture, vapors, aggressive substances, and all this can cause premature destruction.
These protective abilities are especially important when thermal insulation of heating pipes in the basement is carried out, because this is a rather cold and often damp place. The pipeline passing through this room must be protected.
To insulate the pipeline in the basement, you can use heat-insulating paint. This material is easy to apply and retains heat perfectly. In addition, the paint is reliable protection from moisture and, accordingly, (if used metal pipes) against corrosion.
Read more about what paint can be used to paint heating pipes. The article tells about the painting technology and the choice of a specific brand.
Outdoor insulation
Heating pipes that run in the ground or just along the street definitely need thermal insulation. However, when choosing a material and carrying out insulation work, you should be especially careful.
The material must meet the following requirements:
- Low thermal conductivity.
- Moisture resistance - water should not accumulate in the layers of the material. It is especially important to take this into account when choosing a heat-insulating material for pipes that are laid underground.
- Resistance to aggressive environment (the material must easily endure low temperatures, wind).
- Long service life.
- Ease of installation.
Most often, pipes are covered in several layers, each of which is fixed with special tape, wire or rope.
Shown is the insulation of outdoor heating pipes with mineral wool
The first is mineral wool, which is tightly wrapped around the pipe. Then comes roofing material, and it is covered with foil insulation. Multi-layer thermal insulation helps prevent moisture and piping from being exposed to low temperatures, aggressive environment.
There are a significant number of types of insulation. Quite often, a special foam shell is used, which is simply put on the pipe.
Ease of installation and high-quality protection made given view coverage is highly demanded. But in order to prevent premature destruction of such a protective layer, it is recommended to cover it liquid insulation, which, when solidified, forms a dense sealed crust, or foil insulation, which is more stable in bad weather conditions.
At present, thermal insulation of heating pipes with penofol is very common - this is one of the the latest materials, which is a layer of polyethylene foam, which is covered with aluminum foil on one side.
Such insulation can be used to insulate the pipeline, both outdoors, or in the ground, and in the basement and in the attic. The peculiarity of penofol is that it is very thin and soft: there will be no problems with installation.
The aluminum foil prevents cold air and moisture from coming into contact with the pipes, and the foam layer, which has a low thermal conductivity, perfectly maintains the temperature of the coolant.

Output
Thermal insulation of heating pipes is quite simple process which does not require any special skills. After running it, you will notice that the heating quality has become much better. But quite a bit of time and money was spent.

Foreword... Regardless of the material of the pipes laid in the basement of a private or apartment building, steel or metal-plastic - during frosts, with insufficient insulation, frozen water can break the water supply system. Consider the technology of insulating water supply and heating pipes, the requirements for thermal insulation, and also show a video instruction on how to independently insulate water pipes in the basement.
To the owner country house even before the onset of cold weather, you should think about how to properly insulate the pipes in the basement on your own, how to insulate the blind area of the house and the foundation, and what kind of heat-insulating material is better to use for this. The fact is that the water supply system has the most vulnerable areas for freezing; these problem areas are located on the street or in an unheated basement of a residential building.
Insulation requirements for pipes in the basement
If the insulation of the water supply system in the ground is a more laborious issue, then the thermal insulation of the water supply pipes in the basement of an apartment or private house is easier to solve. The main requirements for insulating materials for water pipes are ease of installation, low thermal conductivity and the longest possible operation of the material in a humid environment, since everyone wants to do the job quickly and for a long time.
There are many requirements for pipe insulation, depending on the mode of operation of the material - resistance to temperature, chemical and mechanical stress. To start choosing a suitable pipe insulation, you should list essential characteristics which you should pay attention to when buying:
- the maximum duration of the service life;
- water repellency of thermal insulation;
- incombustibility, the ability to self-extinguish;
- ease of installation, reuse;
- low cost of pipe thermal insulation;
- environmental safety of the material.
More recently, all kinds of improvised materials were used to insulate pipes in the basements of houses - foam rubber, quilted blankets, synthetic winterizer, etc. But today the assortment modern heaters for pipes it is wide enough, so it is quite difficult to figure out this huge variety on your own. In the next chapter, we will consider the most popular thermal insulation materials, for work.
How to insulate pipes in the basement of the house with your own hands
Fiberglass insulation, for example, glass wool Isover or URSA is used more often for thermal insulation metal-plastic pipes... The advantages of glass wool include the low thermal conductivity of the material, but its use requires additional waterproofing using roll materials (fiberglass, izolon, glassine or roofing felt), which will require additional financial costs.
Basalt heaters in the form of cylinders allow you to process water pipes without the additional construction of special trays. Due to its cylindrical shape, the insulation is excellent for insulating heating pipes in the basement of the house. The top layer of waterproofing is usually made of foil insulation, but the cost of this insulation can be quite high.
Foam insulation is more common. Expanded polystyrene shells are used for pipes without an external waterproofing coating. A shell made of polystyrene or extruded polystyrene foam can be used many times (it can be easily removed if necessary), and the low cost and ease of installation satisfy all the basic requirements.
Foamed polyethylene(Penofol, Izolon, etc.) is a moisture-proof, non-rotting, elastic material with good thermal insulation properties... For thermal insulation of pipes, the material is supplied in the form of a hollow tube with a cut, which greatly simplifies installation. Foamed polyethylene pipe insulation can be used in buildings for various purposes.
How to insulate pipes in the basement of a house with your own hands
Thermal insulation of pipes in the basement of a private house with foamed polyethylene or other materials is the most simple technology that everyone can handle. First of all, it is necessary to prepare the water supply or heating pipes for the insulation procedure - to clean all the treated surfaces from dust or dirt. It is possible to insulate pipes in multi-apartment and private ones at any time, before and after their installation.
Thermal insulation of pipes in the basement of the house with mineral wool
Thermal insulation of pipes in the basement with mineral wool is the most time consuming method. Take a roll of basalt or fiberglass wool and cut it into small pieces. Wrap the mineral wool around the water pipe and secure it with a nylon rope - tie the rope around the insulation on one side of the pipe, then circle the rope in a spiral to the end of the pipe and tie the rope securely on the pipe.
On top of the insulation, waterproofing protection must be done. Cut a roll of waterproofing (roofing felt, glassine or foil foamed foam) into pieces of the required size and wrap over the insulated pipe. You can fix the waterproofing with a rope or tape. It is recommended to overlap at least 10 centimeters between the joints of the waterproofing.
Insulation of pipes with a shell made of polyurethane foam or expanded polystyrene
Insulation of pipes in the basement of a house with shells is one of the most simple ways protection of communications from freezing. Pipe insulation made of polyurethane foam, foam or extrusion is produced for different pipe diameters, the shell may have outer layer from foil. When choosing between these three materials, mainly pay attention to the cost, since they have almost the same other characteristics.
Mounting the shell on the pipe is easy and cost effective. For laying, take two halves of the shell, connect them around the pipe and secure with tape. Put the following parts on the pipe with an overlap of the previous part by 10-20 cm. The operation is repeated until the entire pipe in the basement of a private house is protected from possible freezing by the insulation.
Thermal insulation of a water pipe with a polyethylene foam tube
Foamed polyethylene pipe insulation is the simplest and most common way to protect water pipes from freezing in the ground and in the basements of apartment buildings. The material can be installed before laying the pipes by pushing the pipes into the hollow foam foam tube, as well as on the already installed pipes- all you need to do is cut the polyethylene foam tube with a knife.
If pipe insulation cut for installation, then it is necessary to fix the material on the pipe using plastic clamps, aluminized or ordinary tape. The main advantage of this heat insulator is that no additional waterproofing is required. In addition, polyethylene foam can be used for self-insulation gas pipe outside.
