Annotation: The article describes a new method for energy-saving devices of the window opening in the outer wall, wherein the outer perimeter to perform special recess. In the recesses located an additional layer of insulation, which aims to eliminate the formation of cold bridge and improve thermal and technical indicators interface – the minimum temperature on the inner surfaces and reduced thermal resistance. For brick and monolithic concrete walls proposed minimum allowable size of the cross section of the recess analyzed technological capabilities Arrangement of recesses defined direct economic benefit for the new constructive solutions openings in brick or concrete walls. Theoretically, a numerical simulation model for the solution of a brick wall for different thicknesses of insulation in the front with a thin layer of thermal insulation plaster the values of temperature and heat flux. Based on the results of laboratory tests in a climate chamber to determine the reduced heat transfer resistance at the top of the window opening, which values due to additional warming interface compared with a window and a quarter increased approximately 2-fold.
Keywords: thermal insulation of walls, window opening, temperature field, resistance to heat, constant climate сhamber.
