The paper presents the results of thermo technical research of three-layer brick walls with effective insulation layer. The calculation results of three-dimensional temperature field shows the character of the temperature distribution in the thickness of the wall at different thicknesses of the insulation layer. It was found that a considerable thickness of insulation that provides the requirements of modern Building Code adversely affects the performance qualities, durability and resistance to freezing and throwing of the outer layer of bricks. With high thermal protection of insulation layer brick veneer is subjected to a complete freezing for 5 months, while at a low level of thermal protection freezing occurs within three months. That is why, increasing of thermal protection of external fencing needs to be combined with the development of requirements for frost resistance and durability of bricks used for the outer layers of the wall construction.
