The invention is a multiglazed window and a spacer element for the window. The spacer element is made in the form of an elongated body member of generally rectangular cross section. This has an elongated interior chamber located along its longitudinal axis. The chamber is partitioned by a flexible diaphragm into two separate chambers. One of these chambers is in communication through longitudinally spaced-apart apertures with the interior volume of the window. The other chamber is in communication through similar apertures with the outside environment. the diaphragm is preferably of S-shaped configuration having a cross sectional length which corresponds to half of the circumference of the interior chamber. As pressure changes occur between the gas within the window and the outside environment the diaphragm will reform to accommodate the resulting volume change. This maintains equal interior and exterior pressures preventing glass deformation. The spacer element may be a unitary extrusion or it may be a fabrication of separate body portions with a flexible diaphragm that could be of a different material.

A spacer element for glass sheets in a multiglazed window which comprises: an elongated body member of generally rectangular cross section, said body member having first and second face portions and parallel spaced-apart sidewall portions, the body member having an elongated interior chamber generally located along its longitudinal axis, said interior chamber being partitioned by a flexible diaphragm means into two separate chambers not in fluid communication with each other, said diaphragm being of generally sinuous configuration, the ends of the diaphragm being anchored across a diameter of the interior chamber so as to divide the interior chamber into two portions of essentially equal cross sectional area; a multiplicity of longitudinally spaced-apart first apertures which pass between one of the separate chambers and the first face portion; and a multiplicity of longitudinally spaced-apart second apertures which pass between the other separate chamber and the second face portion, so that when the spacer element is in place to separate the glass sheets of a multiglazed window, one of the chamber is in fluid communication with the interior volume between the glass sheets and the other chamber is in fluid communication with the external environment, the diaphragm means being moveable to equalize pressure differences between the interior volume of the window and the external environment.
