Cathedral Series Windows

Features and Benefits

  • The multi-chamber design of our high quality windows helps trap dead air to produce an effective insulating barrier
  • Fusion-welded frame and sashes provide superior structural strength and create a permanent barrier against air and moisture infiltration
  • Ensuring easy operation, the constant force balance system and heavy-duty operating hardware continue to operate perfectly, even after decades of regular use
  • Heavy-duty SteelForce™ reinforcement is placed within the sashes at the meeting rails to ensure extra protection at this very critical and often used location
  • The Intercept Spacer System helps reduce conducted heat loss through the window and is better at retaining insulating gas than many conventional designs
  • Triple-barrier weather stripping between the sash and jamb for superior protection from air and water infiltration
