Moistureproof Characteristic and box-frame construction and its application modulo which possess high airtightness amp; the high heat insulation

摘要

Topic The box-frame construction and its application modulo in order to cancel the dew condensation of box-frame construction internal are offered. Constitution As, from outside the finishing of wall material, 1st ventilation formation, the windbreak moisture permeation sheet, 2nd ventilation formation, the urethane foam, the moistureproof sheet, the gypsum plaster, each stratum of the inner wall facing is formed to sequence, the opening to the inner wall facing is lost from the urethane foam, airtightness Characteristic to the inner wall facing, it is sufficient for the box-frame construction internal section from the urethane foam at the same time with the windbreak moisture permeation sheet and the urethane foam surface with the windbreak moisture permeation sheet and the finishing of wall material outside the cylinder, and outside the cylinder, the 1st ventilation formation which was formed respectively, with 2nd ventilation formation,Permeability, guaranteeing, as it prevents the vapor which invades from the interior to inside the wall, to discharge the vapor which at the same time it tries it will prevent the vapor which invades the box-frame construction internal section, from outside probably to remain inside the wall it features that it makes easy to outside.
