<p>A building element for erecting external building walls, comprising at least one panel (3) of non-yielding cellular plastic serving, together with both an external facing (5) and an internal base panel (2), to form a heat-insulating and sound-absorbing barrier between the inside and outside of the finished wall. A plurality of spaced-apart, vertical sectional elements (6) are secured to the cellular plastic panel (3) and each have at least one flange embedded in and integrated with the cellular plastic panel, and at least one flange projecting or spaced from the outside of the cellular plastic panel to serve as a mounting for the facing (5), compartments for receiving a mineral wool mat (4) or the like being formed between adjoining sectional elements, said mineral wool mat having not only a heat-insulating capacity but also a sound-absorbing capacity superior to that of said cellular plastic panel.</p> |
