Abstract: The panel with thermoacoustic insulation characteristics comprises an insulating layer made of foamed plastic material which has a succession of corrugated portions which are joined by reduced thickness portions. Metallic nets are associated with the opposite faces of the corrugated portions of the insulating layer and are mutually connected by transverse elements which pass through the insulating layer.

Abstract: The apparatus, for manufacturing building panels for construction walls with antiseismic and thermoacoustic insulation characteristics, includes a horizontal table for assembling a panel formed by at least one layer of insulating material and by a pair of metal grids associated with the opposite faces of said insulating layer, means for advancing said panel step by step to a station for inserting, cutting and welding connecting elements of said metal grids. The inserting and welding station includes means adapted to insert the connecting elements transversely to the insulating layer, lower welding means adapted to weld the connecting elements, which pass through the insulating layer, to the lower metal grid of the panel, means for cutting the connecting elements at the upper metal grid of the panel, and upper welding means adapted to weld the cut connecting elements to the upper metal grid of the panel.
