Point-Supported Canopies
Point-supported canopies are commonly used as
features at entrances to offices, stores and residential
properties. They are defined as overhead glazing
where the glass is supported by fasteners that pass
through holes in the glass and that cannot be offered
in annealed glass due to high stresses. The support
structure can be either above or below the glass. This
type of design is specifically excluded from ASTM
E1300 Standard Practice for Determining the Load
Resistance of Glass in Buildings and needs careful,
specific engineering design.
