Creating the right microclimate in any visit is an important task. At the same time, attention is paid not only to the interior space. Insulation of heating pipes on the street is a topical issue today. Many factors influence the process. The stores have a wide range of materials. Therefore, the insulation of heating pipes on the street is a complex of simple actions, which is not difficult to implement. Each stage of creating thermal insulation should take place in stages. In the article we will consider in detail the issue of insulation of heating pipes on the street. This information will be useful to anyone involved in the repair or construction.
Tasks of thermal insulation material on the street
Each material has its own purpose, which is not just insulation, but also to ensure the safe operation of the entire system. In order to avoid difficulties, it is worth disassembling eachfunction and, guided by this, make a choice:
- Elimination of heat losses. The main leakage occurs when the coolant moves through the pipes. Once in an active environment, the carrier loses its performance. It turns out that the heated water, reaching the radiators, partially reduces its temperature indicators. Depending on the material of the pipe, the coefficient of heat reaching the end point will decrease. By creating additional insulation, they prevent heat leakage through walls, air, pipe material.
- No freezing. Insulation of heating pipes on the street will prevent them from freezing in the cold season. Thus, the coolant will be supplied to the right place with minimal changes in the main indicator.
- Exclusion of water vapor formation. The creation of condensate on the surface will lead to additional heat loss. By creating a protective barrier, this problem is easily eliminated.
- Protection against burns. Thermal insulation material helps protect against strong thermal effects. When directly touched by a human hand, there will be no serious thermal effect.
- While inside a building, pipes can impact adjacent materials and deform them. An additional barrier prevents this.
Insulation of heating pipes on the street is one of the first tasks. Otherwise, it will not be possible to bring heat to the desired room with a positive degree indicator. Thanks to insulation, you can increase the performance of the heating system. The heat transfer on the batteries will be maximum, sincethe coolant is as hot as it was originally.
What should be the protective material?
Heat-insulating material must perform serious functions, so high demands are placed on it. This information is in SNiP:
- To achieve the objective, the thermal conductivity of the material must be as low as possible.
- High temperature resistance of the material. The selected insulation must withstand both high and low temperatures without losing its qualities. At the same time, do not react with surrounding objects and do not emit harmful substances.
- If the thermal insulation layer gets wet, its quality will be partially lost. Therefore, its characteristics should include an indicator of water repulsion, otherwise the impact on the pipe is not excluded.
- Vapor permeability. This is important in a situation where there is direct contact with water and the protective layer gets wet. It should dry quickly.
- Breathability - eliminates the appearance of dust, dirt, condensation under the insulation layer.
- In the instructions for pipes, manufacturers indicate operating periods. The insulation material must fully meet the deadlines.
Each item matters when insulating heating pipes on the street. If any destruction occurs, then it will not work to create a protective barrier, and the coolant will quickly cool down.
Which material to choose for protection?
On sale there is a large assortment for every budget. For ease of use, each materialdivided by performance:
- In rolls. It is sold in the same form, it has one foil side. Fixation is carried out over the entire surface by winding, joints from below, around the entire perimeter, the material is fixed with additional fixing rims. The foil side comes out, but it is not a good protection against rain, as users say. For this reason, something additional will have to be applied on top, for example, to create a box or cover the pipe with a casing.
- In mats. No less common material, fixation is done in the same way. There is an extra layer on top to avoid getting wet and mechanical damage.
- Kozhukhovy insulation of heating pipes on the street. Do it yourself most often. It can be soft and hard. The last option is a cylinder of the desired diameter, with slots for fastening. Soft can be made from a flexible material or fabric that has a longitudinal slit. If there is none, then the pipe should be insulated before the installation of the heating system.
- Liquid masses. Masters claim that they are the most effective and it is easy to work with them. They are applied by spraying or simply painted. Spraying requires special equipment, otherwise a brush or roller.
The bulk of manufacturers improve the quality of the material produced to ensure its competitiveness in the market, and therefore the characteristics change. Given the high demand for the product in the market,it is always easy to choose the material for a specific type of work.
How to position the heat pipe on the street?
During the construction process, situations arise when the heating system is not only fixed inside the house, but also needs to be brought to other buildings. In such a situation, the task is to insulate the heating pipes on the street with your own hands. This is not the only case. It is possible to connect housing to a heating main passing by, as well as connection to a nearby boiler house. There are two ways to install pipes: open and underground.
If the pipeline is made of steel, then it is worth preparing the surface using anti-corrosion compounds and more. But modern masters prefer to use polypropylene. Its service life is quite long.
Fixation above ground
How to insulate heating pipes on the street with such an installation? Most often, the pipeline is laid on special reliable supports with the desired height and distance. They cannot be placed on the ground. It is important to take into account the distance from humans and animals, namely the height of the location. The low running line must have a protective casing made of dense materials.
Don't forget about visual perception. Fire safety should also be considered. If flammable materials are used in the protection, then it is important to make additional breaks in the form of non-combustible fragments.
Underground protection
Here it is worth deciding whether there will be a channel or not. The first implies a protective box, so that it does not happenearth pressure on the pipeline, and the second is just a ditch. At the same time, the channel is considered expensive and is rarely used in private homes. How to insulate heating pipes in the ground? If the pipeline is simply laid in the ground, there are limitations. It is unacceptable to use the insulation of heating pipes on the street with mineral wool, as it gets wet. Because of this, its functionality is completely lost.
Main work
There are many ways, each depending on the chosen material. Even with high requirements for the characteristics of such protection, new manufacturers are constantly appearing on the market. Before you insulate heating pipes on the street in winter, you should calculate your budget. Only then can you go to the store.
Polyethylene foam
Some people use shell insulation on the street, but its effectiveness is small. But PPE is the most efficient material with a thermal conductivity of 0.035 W/m2. It goes on sale in a variety of packages and with an extended range of sizes. Visually absolutely not attractive, while it is considered a waterproofing coating. Anyone can work with him, even a person without experience.
The specific gravity is low, so there is no large load on the pipeline. It is not exposed to ignition, when it comes into contact with an open fire, it goes out after contact, without releasing harmful substances into the air. It is better to use sleeves with a side notch, otherwise it is difficult to create a protective layer (you have to overlap, which requirestheir installation rules). This material for insulating heating pipes on the street is the most popular, because it combines high protection rates and low price.
What else is equally effective?
Penofol is a subspecies of the first material. Its difference is one-sided foil. It is implemented in different forms, everyone chooses convenient for himself. There is a high rate of prevention of heat leakage from the main, it is easy to install, but there are a number of disadvantages. One of them is the limitation of the temperature indicator (not higher than +80 degrees). In private houses, creating an autonomous supply and distribution of heat, it would be appropriate to apply. But on the central highways, the coolant indicator is higher, which will lead to the unsuitability of the insulation and the loss of its properties.
Bas alt insulation
Everyone tries to pick up not only high-quality material, but also easy to install. Actual bas alt insulation of heating pipes on the street. To create such protection, bas alt fiber is used. On sale it is in the form of cylinders. The material is of high quality, creates a maximum barrier to the release of heat. Does not load the heat conductor, as well as the retaining structure.
All building materials have their pros and cons. What is noted here: high quality and features, but at the same time less affordable cost. To mount the protective layer, you do not need to have additional skills or experience.
Widely used insulation
One of the most common ways is to use mineral wool. It is wound around the perimeter of the entireline and fixed with a strong wire. The result is maximum protection and low costs, so the demand for the material does not decrease over the years. There are always three main options on sale:
- glass wool;
- stone wool;
- slag wool.
Most often, the first two options act as protection. They meet all installation requirements. But with slag, everything is different, it contains a substance that causes oxidation on the pipe. Therefore, it is necessary to additionally paint the surface of the highway, but the price for the material is low. All three types, due to their breathability, must be additionally hidden in boxes, otherwise mechanical damage cannot be avoided.
Polyurethane foam shell
PPU is a material where the base is rigid and sprayed polyurethane foam. Effectively shows itself during operation, there are more than 25 brands of different manufacturers on the market. There are no difficulties in creating a protective layer, every inhabitant will cope with the work. Insulation of heating pipes on the street with polyurethane foam sheath has its advantages:
- Low hygroscopicity.
- High level of breathability.
- Chemical resistance.
On sale is presented in the form of a shell-shell with a mounting slot and with a foil side. May be of different sizes. After installation on the pipeline, it is required to fix it with clamps, construction tape. Today atalready insulated pipes are available for sale. Their price is higher, but there is no difficulty in installation.
Sprayed PPU is sprayed onto the surface of the pipe with a special apparatus, it is necessary to prepare the surface. The work is carried out in several stages. The first layer dries, after which it is necessary to apply the next one until the required thickness is reached. It is this material for insulating heating pipes on the street that is considered effective, but not everyone can handle the application, as equipment and experience are required.
Foam formulations
This includes synthetic rubber. The cost is low, but the material is effective. Wizards highlight the main properties:
- Good elasticity.
- Material Specific Gravity 40kg/m3.
- High protection performance.
- No reduction in volume during operation.
- Provides fire protection.
- Water and steam do not pass.
- Chemical resistant material.
Rubber is sold in a variety of options - rolls, plates, sleeves and others. After its fastening, additional boxes should also be created, otherwise mechanical impact is not excluded. The price of thermal insulation material is different, the focus is on the manufacturer.
Underground Dive
How to insulate heating pipes on the street with your own hands, what material is better? Understanding this issue when installing heating in the ground, it is worth considering many aspects. The main effect on the surface is ground pressure. Not every design will be able to withstand heavy loads.
Creating a trench is of great importance, you must not forget about the freezing of the soil. If the issue is approached seriously, then the result will be high-quality protection.
Conclusion
Summing up, it is worth noting that the range is large and the choice must be approached with all seriousness. Heat-shielding materials must perform the main function - to prevent the coolant from cooling down quickly. It is important to create a protective layer without gaps, using additional fixing elements - rims or construction tape. It is rare that pipe insulation can act as an independent element. They often need a casing.
