To limit the probability that the performance of glass will fall significantly below expectations, which could lead to failure, which could lead to harm to persons.
[Clauses (e) and (h)] To limit the probability that the performance of insulating glass will fall significantly below expectations, which could lead to inadequate control of heat transfer, which could lead to compromised structural integrity of window assemblies and adjacent exterior wall assemblies, which could lead to condensation on interior glass surfaces, which could lead to deterioration, which could lead to harm to persons.
