Intent
Intent 1: 
To limit the probability that the performance of windows will fall significantly below expectations with respect to:
  • strength,
  • deflection,
  • resistance to condensation, and
  • precipitation ingress and dissipation.
This is to limit the probability of:
  • compromised structural integrity of window assemblies and adjacent exterior wall assemblies, or
  • precipitation ingress or condensation, which could lead to deterioration, which could lead to compromised structural integrity of window assemblies and adjacent exterior wall assemblies.
This is to limit the probability of harm to persons.
