Insulating glass unit with desiccant material, and/or associated methods

Abstract

Certain example embodiments relate to an insulating glass (IG) unit. A spacer system is interposed between first and second substrates. The spacer system helps to maintain the first and second substrates in substantially parallel spaced apart relation to one another, and to define a cavity between the first and second substrates. A desiccant material is located in a body of the spacer system, with the desiccant material comprising a desiccant matrix and a molecular sieve replacement material formed for adsorption at a relative humidity of 10-20%. The molecular sieve replacement material may be a salt or other material (such as, for example, MgCl2, CaCl2, CaO, MgSO4, and/or the like). The cavity may be primarily filled with an inert gas (such as Ar, Kr, Xe, or the like) or a reactive gas (such as CO2). An electrostatically-driven dynamic shade may be provided in the cavity.
