Analysis of the application of external walls with a screen and an air gap

AbstractThe article presents the results of the analysis of the investigated external walls of residential buildings with a screen and an air gap in a dry hot climate. The preferred distance between the wall and the screen was set equal to 30–40 cm. With these thicknesses of ventilated air layers, the air temperatures at the wall surfaces behind the screen did not differ from the outside air temperature. An air gap is formed in the process offorming by metal inserts by hollow formers, which are removed after the concrete has hardened. The production of such panels requires special molding equipment of the factory technological lines for the production of external wall panels.
