How to insulate a water pipe on the street

In winter, emergencies are increasingly common, when water freezes in some areas and the pipeline breaks. Both with hot and cold water. This situation arises due to a violation of the thermal insulation technology of the pipe, or when the insulation is destroyed. Therefore, you need to insulate the water pipe in advance.

Earth insulation

Previously, the main insulating material was the earth. But this approach did not meet expectations, because when the earth got wet, it lost its thermal conductivity coefficient several times. In addition, the lack of such insulation had disadvantages:

  • it was necessary to make large trenches where the ground did not freeze
  • moisture and the activity of the elements affect corrosion
  • under a large layer of earth there is pressure on the pipe, which deforms and destroys it over time.

So the method of insulation of pipes with earth is not effective, and requires additional thermal insulation.

Insulation material

In order to insulate the water supply on the street, we recommend using such materials:

  • glass wool
  • basalt
  • expanded polystyrene
  • synthetic rubber.

Each material has both advantages and disadvantages. Therefore, when choosing it, you should approach it wisely. The company "Sunprace" offers two of the most popular insulation for the insulation of water pipes on the street.

Basalt fiber

It is made of basalt stone, which provides protection of fire and environmental safety. A large amount of air that is located between the fibers and provides insulation.

It is made of cylinders and semi-cylinders, which are covered with a thin layer of aluminum foil, so that there is more reliable resistance to impacts.

The fiber has a good density and is UV resistant, can be used and reused for a long time.

If used in conjunction with waterproofing, you will be satisfied.

Synthetic rubber

The most effective material for heat preservation in engineering networks. It looks like a hose with a longitudinal section, inside of which there is an adhesive composition.

Among the advantages should be highlighted:

  • high coefficient of thermal conductivity
  • does not absorb water
  • protects against corrosion
  • long-term use is possible
  • resistance to tears and sunlight.


Even in the most severe frost, the pipes will never freeze.

Observe the correct installation technologies, select only effective insulation materials and then the plumbing will never let you down for a long time. You will be confident and comfortable living in your home.
