Miami-Dade-certifi ed louvers installed at Brickell City Centre, a 4.9-million-sq-ft, mixed-use development in downtown Miami. Photograph courtesy of Construction Specialties Shelters, a Miami-Dade NOA-approved louver would not meet FEMA requirements. The bottom line: When in doubt about the type of severe-duty louver to use, consult the relevant building and mechanical codes. Installation Does wall construction (substrate) affect the method of installation of louvers? Yes. Installation hardware and methods vary depending on substrate, louver model, and louver manufac t u r er. Rev iew t he MiamiDade NOA-approved and/or the Florida Building Code-approved drawings for more information. Can Florida Building Code-approved or Miami-Dade NOA-approved louvers be glazed into a curtain wall? There is nothing in the Florida Building Code or the Miami-Dade requirements that prohibits 32 2021 AMCA inmot ion such an installation. Whether a louver can be glazed depends on how it was tested and evaluated. Refer to model-specifi c NOA or FPA documents for allowable installations. How should a Florida Building Code-approved or a Miami-Dade NOA-approved louver be undersized? The amount of undersizing varies by louver model and manufacturer. Typically, a rough opening size is provided at the point of order, and the manufacturer undersizes the louver accordingly. See the manufacturer's model-specifi c catalog/submittal sheet for more information. The bottom line: While non-severe-duty louvers should be installed per manufacturer installation instructions and/or engineer-of-record and/or installationcontractor requirements, Florida Building Code-approved and Miami-Dade NOAapproved louvers have very specifi c installation requirements. www.amca.orghttp://www.amca.org
