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.
