The insulation of sewage pipes is carried out to prevent their freezing in winter. This process is quite bye and the owner of the house, you only need to pay special attention to the most vulnerable sites, which are located outside the house and in places of connection with wells, pumps. Consider how and from which materials you can perform high-quality insulation.
1
Each insulation, presented in the building materials market, has its advantages and disadvantages. When choosing a material, you should pay attention to the following characteristics:
ease of installation;
nonseasing;
ability to maintain the operating temperature;
poor absorption of moisture, water;
durability;
immunity to the action of chemical, biological compounds and mechanical impacts;
low thermal conductivity.

Mineral wool and glass gamble are available, have a small cost, low density. Require additional isolation, since over time they are joined and carried out moisture. Therefore, you need to put in the box or wrap the rubroeroid. In this case, the installation time and the cost of the entire material increases.
3
For warmer climatic zones, the ideal option is to use foamed polyethylene. It is easy, attached tightly to the pipes and over time does not lose heat insulating properties. But for the more severe climate, foamed polyethylene is not effective. Available in the form of a canvas and hollow tubes.

Hells of foam and polystyrene foam were very well established. They look aesthetically, therefore they are used for the insulation of sewage pipes that are both inside the house and located in the ground. This material does not absorb moisture, easy to use. But such shells having the necessary diameter are rare. For insulation, the usual sheet foam pipe is placed in the box.
5
The cylinders from the basalt insulation are practical, possess all the necessary characteristics, but they are quite expensive.
6
For a more harsh climate or in the case when the house is properly used, use a waterproof heating electrical cable. This method requires considerable costs of electricity consumption. Do not lay the cable right into the pipe, but put under the outer, bottom wall. Cable cable in several places in scotch and wrapped with waterproofing material.
7
The process of insulation for all types of material is the same. If no insulation is applied, the trench is discouraged at a depth below the maximum level of primerization of the soil. Mostly 1.5-2 meters. The sand is poured on the trench to a height of 10 cm, they pave the pipe and fall asleep with a layer of sand, clamzit, and then the ground. This method is laborious, as it requires the performance of a large amount of earthworks.

In cases where there is no possibility to arrange pipes at the depth or depth of the primer of the soil, the insulation discussed above is used. If you have chosen the heat-insulating shell, then wear it onto the pipe and fix the scotch. When using glass gambles, foamed polyethylene, they are wrapped 1-2 times around the pipe and fastened with scotch.
All thermal insulation materials work according to one principle: form an airbag and prevent the penetration of the cold. When choosing a method of insulation, follow the convenience of mounting, the location of the sewer pipe and the climate in your area.
