Thermal conductivity is one of the key parameters for wall materials. The thermal conductivity of the walls determines the comfort of the temperature regime in the house, regardless of weather conditions. The lower the thermal conductivity of the walls, the easier it is to maintain the microclimate in the house. A house with a low thermal conductivity is called an energy-efficient house with low heating or air conditioning costs. Such a house is warm in winter and cool in summer with minimal energy costs.

As can be seen from the data, the best indicators are for polystyrene foam and mineral wool, whose indicators are more than three times higher than those of other materials.
