as the article says:
” Yes. The glazing panel is considered new construction and must meet the requirements for new construction”

Understand that there are more ways than one to achieve these requirements.

Yo can always replace the glazing in kind. and then add a roll shutter or accordion shutter, screen etc.
to fulfill impact and wind load requirements.
In additions this can add energy, privacy and security benefits beyond the original window.

Following the above clarifications is not a problem. I do question the understanding of the recipient of the upgrade to the storefront mentioned in point “E”. When replacing storefront glass with impact rated glass there may be difficulties with the glazing bead/legs (because impact glass is thicker) and the existing anchorage. This is my point – just because an existing storefront not designed for impact glass recieves impact glass replacement this does not make the installation an impact rated installation. Typically an installation meeting impact requires an increase in the anchorage pattern and a stronger anchor than used in typical construction. Impact rated designs also allow for increased frame coverage on the glass (bite) and the existing frame does not provide this. bottom line ids the replacement is better but not an Impact Rated Package. thanks, tom
