The article regards experimental studies on determining the value of thermal conductivity coefficient for angle brackets of new construction. Angle brackets are used in ventilated facades systems. Such systems consist of an angle bracket (called a console), an insulation layer and an outer cladding that provides protection against atmospheric conditions. The angle bracket is the main element that supports the outer cladding to the wall of the building and is subject to many of the requirements of the applicable regulations. Measurements were made using a special measuring system and a program that controls the measurements and data recording was written in LabView. The study showed a significant reduction in the thermal conductivity coefficient for the element made of corrosion-resistant steel. Analysis of the results shows that the angle brackets with drilled holes have a lower thermal conductivity compared to the angle brackets with solid walls. This effect can be explained by the formation of narrowings of conductive material, that extend the heat flow path. Research has shown that systems based solely on aluminium do not meet the basic requirements of building regulations in force.
