Understand how product approvals, design pressures, sizes, glass, and installation details fit together in high-wind projects.
Miami-Dade and Broward County projects in the High-Velocity Hurricane Zone require careful coordination of current code criteria, product approvals, design pressures, opening sizes, glass, anchors, substrate, and installation details. A product described as Miami-Dade approved is not automatically eligible in every configuration or at every address.

Key takeaways
The decisions to resolve before you order
Verify the current approval document, model, size, glass, pressure, and installation option.
Use project-specific design criteria instead of selecting from a ZIP code alone.
Confirm mullions, anchors, substrate, edge distances, and limits for every opening.
Coordinate permit submittals and revisions before fabrication and installation.
Miami-Dade NOA and Florida Product Approval basics
A Miami-Dade Notice of Acceptance and a Florida Product Approval are document systems that describe tested products, limitations, and accepted installation conditions. The useful review goes beyond the cover page. Read the model description, drawing sheets, glass tables, size limits, pressure tables, hardware, mullions, anchoring, substrates, notes, and expiration or revision information.
The accepted path can vary by jurisdiction, product, building, and project scope. Do not assume that a statewide approval replaces every local requirement or that an NOA is required everywhere in Florida. The authority having jurisdiction and project professionals should confirm the current submittal basis.
Selecting HVHZ impact windows by opening
Start with an opening schedule that includes location, dimensions, operation, required positive and negative pressures, impact criteria, frame or substrate, finish, and glass. Cross-check each line against the approval tables. Large openings, corner zones, upper floors, doors, mulled assemblies, and unusual substrates may require different configurations.
If a proposed size or pressure falls outside the listed limits, do not interpolate or substitute without an accepted basis. A different glass makeup, reinforcement, frame, mullion, anchor pattern, or product family may be required. Resolve those changes before fabrication so the permit set, quote, and order acknowledgement remain aligned.
HVHZ permit and inspection file
Organize documents by opening or product type so reviewers and installers can trace the approved configuration. Current local forms and project requirements should be confirmed directly with the jurisdiction.
Project design criteria and required positive and negative pressures.
Current approval documents, drawings, calculations, and product schedule.
Permits, revisions, inspection records, labels, installation photos, and closeout documents.
What to confirm before ordering impact windows and doors
Impact eligibility belongs to an exact assembly. Prepare the project requirements and opening conditions so the selected system can be checked against the applicable approval.
Start with the project requirements
Provide the installation address and the design criteria supplied for the project, including required positive and negative pressures and any applicable impact or exposure requirements. Identify each opening by ID and quantity. A general product category cannot determine the requirements for a specific building.
Identify the exact proposed assembly
Record the model, overall dimensions, individual panel arrangement, glazing package, frame material and operation. Sliding drawings may show fixed-panel, stacking and pocket arrangements within a series. Those illustrations describe available layout concepts; they do not establish that every illustrated arrangement carries the same impact approval.
The TIS.67 drawing likewise shows multiple window operations within the series. Confirm the approval for the actual window being quoted, rather than extending a fixed-window approval to a different operating type.

Match the approval to the opening
Request the applicable approval number and current document revision, then confirm the permitted size, glass, configuration and pressure range. The record should identify the proposed assembly clearly enough to compare it with the quote and opening schedule. General family brochures and profile drawings are useful for selection but do not replace that verification.
Check the attachment condition
Document the wall construction, substrate and opening condition. Have the project professional or installer review the permitted attachment details, anchors, spacing, edge distances and support for the exact assembly. Those values must come from the applicable installation and approval records, not from a generic installation guide.
Keep appearance choices in the same review
Coordinate the desired finish, hardware, sill and panel layout with the approved assembly. A change made after the initial quote, such as a larger size, different glass or another sill, may require the assembly to be reviewed again. Use a consistent opening ID and drawing revision so those changes remain visible.
Before production
Confirm field dimensions and the final ordered frame size.
Match the model, layout, glass and hardware to the quote.
Identify the applicable approval and permitted installation condition.
Resolve the floor transition, drainage and surrounding construction.
Keep the final assembly records with the order and installation package.
Frequently asked questions about Miami-Dade, HVHZ, and Impact Window Approvals
Topic-specific answers from this guide, followed by the ordering and project questions customers ask most often.
Does every Florida project require a Miami-Dade NOA?+
Requirements vary by jurisdiction and project. Florida Product Approvals and other accepted documentation may apply outside the HVHZ. Confirm with the local authority and project professional.
What does HVHZ mean for impact windows?+
HVHZ refers to the High-Velocity Hurricane Zone in Miami-Dade and Broward Counties. Projects there follow specific code, approval, design, installation, permitting, and inspection requirements that must be verified for the property.
Is a Miami-Dade NOA the same as a product model number?+
No. An NOA is an approval document with defined models, configurations, limits, and installation details. The model name alone does not establish the approved size, glass, pressure, or anchor condition.
Can one approval cover every window in a building?+
Only when every opening falls within that approval’s eligible operation, size, glass, pressure, frame, mullion, anchor, substrate, and installation limits. Many projects require more than one configuration or product family.
What should I verify before using Miami-Dade, HVHZ, and Impact Window Approvals to place an order?+
Verify the current approval document, model, size, glass, pressure, and installation option. Use the guide to organize the decision, then verify the exact model, opening dimensions, glass, finish, pressure requirements, approval, anchors, substrate, freight, and field scope for the real project before fabrication begins.
Does Miami-Dade, HVHZ, and Impact Window Approvals replace local approval or installation review?+
No. The discussion of miami-dade noa and florida product approval basics provides a planning framework, but the project address, current permit criteria, building conditions, product documentation, and installation method still require project-specific review by the appropriate local professionals.
Can the recommendations in Miami-Dade, HVHZ, and Impact Window Approvals be used for custom-size openings?+
They can support early planning, but custom openings must remain within the selected system's documented size, glass, reinforcement, mullion, pressure, and installation limits. Final dimensions and configuration details should be approved before production.
What project information should I collect after reading Miami-Dade, HVHZ, and Impact Window Approvals?+
Create an opening-by-opening record with dimensions, photographs, desired operation, glass, finish, performance criteria, access, delivery needs, and installation scope. Use the hvhz permit and inspection file section to identify the remaining questions that should be resolved in the quote or project review.
We will compare the exact manufacturer, model, dimensions, configuration, glass, finish, pressure rating, quantity, delivery scope, warranty, and lead time, then provide our best verified price.
