Heat and sound insulating rear ventilated wall facing panel - has retainer opposite tongue and groove and has provision for compensating wedge

摘要

The insulating rear ventilated panel is used for the protection of old or new buildings from heat, cold and noise. The element is curtain-hung and has provision for rear ventilation(3). It comprises insulating material(2), spacers and a facing panel, and a holder. The retainer fish-plates(6), for attachment to the structure, are at the top and right. At the bottom left a groove is thrust onto a tongue(7), and air is limited by the insulating panel. The retainer's length is extended, to permit wedge insertion between the wall and the facade element, to compensate(8) for unevenness. Rain-proof perforation may be incorporated to increase the ventialation. elements may be prefabricated and mass-produced, at low cost.
