The principle of operation of this type of insulation is as follows: a layer of polyurethane foam is applied to a steel pipe, and then a continuous plastic pipe is put on for high -quality protection against moisture. So, isolation of polyurethane foam consists of a steel pipe, with a layer of thermal insulation and all this is covered with polyethylene shells.
In order to monitor the moisture of the material, the CSC system is installed in thermal insulation in the form of wires, and when moisture occurs, the resistance between the steel pipe and them, which makes it possible to take the appropriate measures in a timely manner. You can order a kitchen here.
This type of isolation has a number of advantages and disadvantages.
They have high thermal insulation properties, serve for a long time, do not require an anti -corrosion coating for insulation to a steel pipe, have a CSK system and a guarantee of up to five years.
But the heat resistance of this isolation is relatively low, not more than 130 degrees, the cost is too high and the material and work, the strength is low, the insulation is not resistant to mechanical influences, the adhesion is low compared to other materials, the level of sorption moisture is high, which leads to corrosion of metal pipes, Therefore, water protection is required, and this is additional costs. And another significant drawback is that when damaged the shell, moisture that enters the structure cannot be removed.
