Adsorbent for use in double glazed windows

摘要

Novel, hollow, low-density agglomerates for use in sealed insulating glass windows to adsorb water vapor, and optionally organic materials, present in the cavity between the two glazings. These agglomerates provide sufficient but not excessive amounts of zeolitic and other adsorbents when used to fill all portions of the spacer tube located at the peripheral sides of the double glazed unit, thereby greatly facilitating the filling of such spacer tubes and the fabrication of the overall unit.
