Seal Durability in Insulating Glass Units: Summary of Technical Issues and Recommendations to the Department of Energy
FREE Registration is required
Overview: The content of this report is based on discussions with 13 experts in the field of IGU seal durability and performance. The principal degradation mechanisms of seal failures are loss of adhesion between the sealant material and the glass or spacer or rapid permeation of gases through the sealant material (s). The causes of failure generally result from a poor choice of materials, careless manufacturing practices, poor installation practices, or details of the IGU design when exposed to a service environment of solar irradiation, temperature extremes, and water or water vapor.
