Traditionally built homes use three or more studs in exterior wall corners leaving minimal space for insulation, resulting in  thermal losses. By only using two studs and a clip to help hold the drywall, high-efficiency corner framing allows for insulation in the corners of a home and reduces heat loss. This in turn minimizes cold spots at corners while saving both energy and cost. It also helps minimize corner cracking because the two sheets of drywall that meet at the corner are effectively attached to the same stud, eliminating differential movement.
