Guidelines for the Appearance of IGU Edges

Purpose:

• This Paper addresses issues related to the appearance of insulating glass unit (IGU) edges in both captured and silicone structural glazed (SSG) commercial glazing systems. Components of IGU edges are discussed, and acceptance criteria provided where appropriate. It is intended to address both vision and spandrel IGUs. Viewing and acceptance criteria are the same for both vision and spandrel units. These guidelines assume IGUs are sized correctly for the opening dimension and glazed according to NGA glazing guidelines. It was written to address two lite (double glazed) IGUs. However, much of the information pertains to IGUs with three or more lites (triple glazed, quad glazed, etc.
