A multi-pane glass unit includes a first outer glass pane and a second outer glass pane facing each other, a first inner glass pane between the first outer glass pane and the second outer glass pane, a first spacer located between the first outer glass pane and the first inner glass pane, and a second spacer located between the second outer glass pane and the first inner glass pane.

Provided is an apparatus for manufacturing a multi-pane glass unit. The apparatus includes: a first plate configured to hold a first glass pane; a second plate configured to hold a second glass pane such that the second glass pane faces the first glass pane; and a conveyer including a first portion configured to convey the first glass pane onto the first plate and a second portion configured to convey the second glass onto the second plate.

Certain example embodiments relate to electric-potential driven shades usable with insulating glass (IG) units, IG units including such shades, and/or associated methods. In such a unit, a dynamic shade is located between the substrates defining the IG unit, and is movable between retracted and extended positions. The dynamic shade includes on-glass layers including a transparent conductor and an insulator or dielectric film, as well as a shutter. The shutter includes a resilient polymer, a conductor, and optional ink. If shutter coil skew is detected, voltage(s) may be applied one or more areas of the on-glass transparent conductor to compensate for or otherwise attempt to correct the detected coil skew.
