The influence of ventilated air channels on the distribution of temperature and moisture in the mineral wool plates of roof construction

Abstract

At present ventilating structure of two diagrams is used for flat roofing. These are flat roofing's with or without ditches (air channels) in the layer of thermal insulation material. Besides air channels, two layers of mineral wool of different compressive strength or one layer double-density mineral wool can be used, laying a damp-proof course on it. In the other case, special mineral wool plate with ditches every 200 mm is used for ventilation of flat roofing thermal insulation material. [...]
