Edge sealing of a laminated transparency

摘要

A heatable laminate includes a first substrate; an electrically conductive member on a portion of the first substrate; a pair of spaced bus bars each bus bar being in electrical contact with the electrically conductive member; a second substrate overlaying and the electrically conductive member and bus bars; an interlayer positioned between the two substrates; a first leads connected to one of bus bars and a second lead connected to the other bus bar, each lead having an end extending beyond the periphery of the first substrate to provide external electrical access to the bus bars; an electrically non-conductive sleeve over selected portions of each of the lead; and air barriers along selected portions of the sleeve to prevent air from enter between the substrates.
