A diaphragm for electrolytic cells for the electrolysis of aqueous salt solutions is comprised of an electrochemically active porous portion attached to an electrochemically inactive substantially fluid impervious portion. The electrochemically inactive portion is comprised of a fabric layer attached to a fluid impervious film layer. The electrochemically active porous portion is comprised of asbestos fibers, preferably deposited on a porous, lightweight thermoplastic fabric.
