A heatable window (e.g., vehicle windshield) includes a heatable layer including one or more conductive layers. The heatable layer may be a single layer conductive coating, or alternatively may be a multi-layer heatable coating including one or more dielectric layer(s) in addition to one or more heatable conductive layer(s). Bus bars are provided so that a voltage may be applied across at least one conductive layer of the coating, in order to heat the layer so that the coating generates heat for defogging, deicing and/or desnowing the window. At least a portion of one of the bus bars includes both an underlying conductive base layer portion, and an overlying conductive braid portion that is conductively attached to the conductive base portion. The braid portion significantly increases the current capacity of the bus bar portion if so desired.
