Types of materials for thermal insulation of external communications

mineral materials, glass wool insulation

made with different materials, which differ in their properties and methods installation.Each business manager selects material according to the needs and budget.So what are the materials for insulation of pipes exist.

This is the most affordable and budget option for insulation.These materials are excellent for insulating qualities, and are not subject to combustion and high temperatures.Glass wool, as well as mineral materials are often used in industrial plants and utilities, because of its cheapness.

Heaters of this type are glad drawbacks:

1. laborious and inconvenient installation.Attach the pipe to the surface it must be thorough.
2. Thermal insulation properties, such as mineral wool and glass wool are lost when wet.Therefore, this type of insulation is not always helps to keep pipes from freezing, and the top is generally additionally wrapped their waterproofing material.
3. Low durability of glass.Therefore, the approval of a budget option seems highly controversial.
4. material is not entirely safe for workers to install it, and can cause allergies.

foam polyethylene - a great alternative to other insulation.

This material is used more for sealing pipes of polypropylene.Trubopodobnogo manufactured as a sleeve or shell with a slit which facilitates its fixing to the pipe.The installation of this heater is not working, it will last a long time without any change in performance.Producing shells for pipes of different diameters.

main disadvantage of polyethylene foam - high flammability.Therefore, with his help not produce insulation pipes near electric cables.For fixing using adhesive tape shell.The latest novelty of the construction market - polyethylene foam in cylinders, which can be sprayed as a paint.such a coating is well fixed on the pipe surface and does not require additional fixation.

foam, also known as polystyrene foam

much tougher polyethylene, and due to its structure, it is absolutely not afraid of water and has a low thermal conductivity.The foam also has drawbacks - it is flammable and is therefore considered to be a fire hazard.In addition, surprisingly, he loves to eat various rodents, and therefore can not be responsible for its longevity.

Polyurethane foam - insulation with a lot of merits

In appearance it is very similar to a conventional foam, but other cell structure.Benefits of foam following:

• heat loss is reduced to zero;
• moisture resistance;
• lightweight material;
• life of up to 50 years without any loss of performance;
• rodents do not like him, and it does not breed mold or fungus.

sale also features a polyurethane foam in cans, sprayed similarly foamed polyethylene.

disadvantage of this material - the fear of ultraviolet radiation.When exposed to sunlight it decomposes.Therefore, it should be painted on top.

alternative methods of thermal insulation of pipes is a method of "pipe in pipe" where the natural insulation is an air gap, as well as thermal paint.However, thermal paint or another liquid ceramic material is quite expensive, but promising.

As you can see, a huge amount of thermal insulation methods, and the choice is yours.
