Foam insulation

Requirements for thermal insulation

Also important is the property of a heater to prevent the heating of working fluid or gas. This function is the most important for air conditioning systems, gas transmission networks and refrigeration plants. In addition, the insulation can extinguish the noise and vibration created by the liquid being transported through the pipe.

1. The price of the material must correspond to its thermal characteristics.
2. This or that type of insulation must be suitable for pipes of the correct size. For example, heaters made in the form of cases, its internal diameter should correspond to the outer diameter of the pipes.
3. Easy installation and operation
4. Lowest moisture absorption. When the insulation is saturated with moisture, it loses its insulating properties and becomes unsuitable, so you should choose materials that have hydrophobic properties.
5. Compliance with sanitary and fire regulations.
6. Durability of operation

Foamed polyethylene

Another name for this type of insulation is Energoflex, which is one of the leading materials among heat-insulating ones. It can be used not only for pipe insulation, but also for other purposes, as it is easy to install and affordable. Energoflex is produced in the form of rolls, the thickness of the sheet of material in which is less than 2 cm, and the width - 1.2 m. There is also a special insulation for pipes - cases, the thickness of which is 9-13 mm, cut from one side. Sometimes an internal surface is applied with an adhesive coating, which makes the installation of this insulation unusually simple.

Foam insulation

One of the most popular materials used for heat insulation of heating systems. Its distinctive properties are: high strength, excellent heat engineering properties, fire safety. Produced in the form of a shell-two halves of a hollow cylinder, the edges of which have the form of a lock. The features of its installation allow the insulation to be used several times, which has a great economic advantage, especially for use in temporary structures. Due to its excellent characteristics, foam plastic insulation for pipelines is popular among other materials of this kind.

Fibrous insulation

Such insulating materials are the lowest in their cost. Basically, it is a roll material, which is easily wrapped around the pipe and fixed with screeds or stainless wire. In the same way fibrous insulants are manufactured in the form of hollow cylinders, which are mounted on pipes. This category of thermal insulation includes products from mineral and fiberglass wool, basalt products.

The disadvantage of this type of material is the need for additional waterproofing. Since glass wool is easily saturated with moisture and loses its thermo-technical value, it must be covered with hydrophobic materials. If the pipes are insulated indoors, this helps prevent the ingress of microparticles of the material into the air.

Other types of insulation

Every year, more and more insulation materials, different in price, properties and installation features, appear on the market. A striking example is foil insulation - a layer of foamed polypropylene, applied to the foil. In addition to their excellent insulating ability, they also have heat-reflective properties. This type of insulation has the following advantages:

• Easy installation - just wrap the insulation around the pipe and secure with adhesive tape or screeds.
• . Wide application range - because they also reflect heat, sheets of foil insulation are attached behind the radiators, increasing heat transfer to the room.
• Low cost

Thermal paint is a relatively new type of insulation, used primarily on an industrial scale. The coating has high stability and excellent heat engineering properties. The installation of such insulation consists in spraying or applying a thermal ink to the pipeline with a brush. It is worth noting that this material is not cheap.

Heat insulation of heating pipelines and hot water supply networks is necessary and economical. With the correct choice and installation of insulation, you can save about 30 percent of the energy going to heat the coolant. Choosing Energoflex, mineral wool, glass wool, or foam plastic insulation, you can not only get rid of unwanted heat loss, but also extend the life of the system.
