ABSTRACT OF THE DISCLOSURE: An extrudable glass fiber-reinforced polyvinyl chloride composition made up of polyvinyl chloride resin having a K value between 55 and 75, glass fibers, and inorganic fillers different from the glass fibers, and conventional additives, including mold release agents, stabilizers, pro- cessing aids, and colorants for the production of extruded articles. The composition contains, per 100 parts by weight of a polyvinyl chloride resin, 50-100 parts by weight of glass fibers having a diameter of between 5 and 25 µm with a length up to 12 mm, and 5-25 parts by weight of a mineral filler having an average particle diameter of below 50 µm and exhib- iting a modulus of elasticity in the extrusion direction of an extruded product of at least 8,000N/mm2 at 23°C. And a profile strip for the manufacture of frames for windows or doors comprising a core profile formed of reinforced synthetic resin and a synthetic resin shell surrounding at least a part of the core profile, the core profile being formed of the above composition.
