  The India-based Neutrino Observatory (INO) is planning to build a magnetized
iron calorimeter detector (ICAL) in which Resistive Plate Chambers (RPCs) will
be the active detector elements. A study of the performance of RPCs, made using
electrodes of various thicknesses, is pivotal in optimizing the design
parameters of the ICAL RPCs. We fabricated RPCs with glasses of various
thicknesses and studied their performance in the same environmental conditions.
A study of detector efficiency, noise rate, time resolution and charge
distribution is presented in this paper.
