Abstract: The paper analyzes the existing design solutions of insulated frameless vaulted coverings made of thin-walled steel cold-curved arch profiles and the problems arising during their operation. In the cold season, condensation forms on the inner surface of the profile and in the thickness of the thermal insulation layer, which significantly reduces the heat transfer resistance of such structures and leads to an increase in operating costs for heating. In particular, it leads to an acceleration of the corrosion processes of profiles and to a reduction in the service life of both the roofing and the entire building or structure. To solve the removal of condensed moisture, it is proposed to improve the design solution of the vaulted coating insulated by the double arch method by creating a ventilated air layer. The technical and economic assessment of the adopted design solutions of the insulated frameless arched hangar was carried out, on the basis of which the rationality of the application of the proposed improved design solution was justified.

Keywords: frameless vaulted coating, heat loss, energy saving, payback period.
