ELEMENT DE PAROI PREFABRIQUE

摘要

The invention discloses a prefabricated partition having high acoustical insulation value and comprising two parts which are symmetrical on either side of a plane parallel to and between the outer facings. The frame members of one part being adhered to the frame members of the opposite part by an adhesive over at least a portion of the adjoining frame surfaces. To reduce the area of contact between the rigid frames they may be recessed along a portion of their adjoining surfaces and the recesses filled with an elastic foam. The frames are preferably of a rigid foam material.
