AMCA InMotion - September 2019 - 34

ANSI/AMCA Standard 540 and ANSI/AMCA Standard 550
are required by the ICC in hurricane areas everywhere.
To ensure proper compliance and to learn of any special
circumstances, designers and specifiers are advised to check
with local authorities.

Conclusion
By specifying louvers that bear the AMCA listing label for
high-velocity-rain resistance in hurricane-prone regions
and the AMCA listing label for impact resistance in windborne-debris regions, design professionals can rest assured
knowing their specifications comply with building-code
requirements.

Although Miami-Dade approval has been considered
the default standard for louvers in hurricane areas-even
those outside of Florida-for years, it is not required by
code anywhere but in Florida high-velocity hurricane zones.
