ABSTRACT:
Certain example embodiments of this invention relate to a vacuum insulating glass (VIG) unit surrounded by two glass substrates, with at least one spacer element being disposed adjacent to and/or cradling the VIG and with a sealant sealing the entire unit at each end of the VIG, thereby reducing the chances of the VIG being damaged and/or improving the insulating features of the entire window unit. In certain example embodiments the spacer may be substantially U-shaped, whereas two pillar-like spacers may be used in connection with certain other example embodiments. The spacer element(s) may be butyl-based, foam-based, warm-edge spacer element(s), etc. The sealant may be polysulfide based, one- or two-part silicone based, polyurethane based, a dual seal equivalent sealant product, a hot melt butyl based sealant product, etc. The R-value of the window unit may be at least about 11, but typically is about 15-16, when measured at the center of the lite.
