29、rtical GlazingGlazing used in an in-stallation in which the lower edge of the glazing is a maximumof 6 ft (1.8 m) above the walking surface. The glazing isusually vertical, however may also be sloping in or out fromthe vertical plane. The glazing can be approached within 10 ft(3 m) or less (if dista
30、nce is greater than 10 ft (3 m) seeLaminated Overhead Glazing). Interior decorative glazing willbe judged according to laminated vertical glazing criteria.4.2.2 Laminated Overhead GlazingGlazing used in aninstallation in which the lower edge of the glass is more than6 ft (1.8 m) above a walking floo
31、r level or cannot beapproached within 10 ft (3 m). The glazing is usually slopingfrom the vertical plane, however may also be vertical. Slopedglazing is considered any glazing that slopes more than 15from the vertical in any direction.4.2.3 Laminated Spandrel GlazingGlazing used in aninstallation in
32、 which the glazing is only viewed in reflectionfrom the buildings exterior. The glazing is usually installedvertically, however, may be at a slope to the vertical plane.Laminated spandrel glazing shall be inspected using the criteriaof vertical or overhead laminated glazing.
