LOW THERMAL CONDUCTIVITY METAL-POLYMER-METAL SANDWICH COMPOSITE SPACER SYSTEM FOR VACUUM INSULATED GLASS (VIG) UNITS, VIG UNITS INCLUDING COMPOSITE SPACERS, AND METHODS OF MAKING THE SAME

摘要

Certain example embodiments of this invention relate to vacuum insulated glass (VIG) units, and/or methods of making the same. A composite spacer system design helps improve VIG unit thermal performance by replacing high thermal conductivity spacers with composite designs. Decreasing the thermal conductivity of the spacer system can dramatically increase the center of glass R-value of the VIG unit. Certain example embodiments incorporate as spacers in a spacer system a low thermal conductivity metal-polymer-metal sandwich composite that benefits from a low thermal conductivity polymer (such as, for example, polyimide, polyamide, polyether ether keytone, or the like) in combination with the mechanical strength of metal or metallic top and bottom layers (e.g., formed from stainless steel, titanium, or the like).
