Abstract
Heat-insulated and noise-suppressed ventilation conduit wherein a ventilation air duct (1, 2) and a space (3) for a fan (8) formed therein are defined by selfsupporting walls of plastic which is inherently heat-insulating and noise-suppressing. An aperture in the ventilation conduit for admittance to said space is closed by a plate (9) on which the fan is mounted. This plate forms an air outlet or inlet opening (13), respectively.
