Abstract of the disclosure A moulded strip, particularly for use in window frames or the like, of the type of a core section made of a plastic matrix with tiny cavities disposed within a generally tubular shell of PVC or the like. The core is composed of a matrix of polymerized methylmethacrylate cross-linked to the tubular shell and having tiny hollow silicate spheres as a filler. The invention presents the improvement of combining a high mechanical strength with a substantially reduced shrinkage of the core, due to an improved bond between the core and the shell.
