Insulated air ducting cavity facing wall

摘要

The external wall, with inner and outer shells and if necessary with intermediate rigid or movable heat screening units, has provision for ducting air, and is suitable for reducing heat loss in winter or excessive heat from the sun in summer, in walls contg. a large proportion of glazing.A heating device (16) is fitted in the area between the outer and inner shells (10, 11), pref. in the area most subject to condensation.It can serve as a structural element to consolidate (15) the inner shell, and can be in the form of a heat radiator, with adjustable reflector. This provides for special tempering of critical pane or panel areas, and checks condensation formation
