ABSTRACT:
A facade is heat-insulated by a number of synthetic resin foam panels extending in at least two horizontal facade regions one above the other, and being internally ventilated by ducts extending preferably at an angle of about 45.degree. with a horizontal plane and intersecting each other. Between the two facade regions there extends horizontally a flame barrier having the configuration of a beam and containing barrier ducts each of which connects a ventilating duct in the lower facade region with another ventilating duct in the upper facade region. A groove or channel extending longitudinally in the beam can intersect the barrier ducts and have an open end which is preferably directed downwardly so that a fire in the lower facade region will cause a uniform heating of the groove and adjacent barrier ducts. Blocking agents, e.g. elongated strips are inserted in the groove or in each of the barrier ducts and are adapted to expand, especially by foaming, when a critical temperature limit is reached in the barrier ducts.
