About CDF Distributors

What Florida Product Approval numbers do CDF's hurricane doors carry?

CDF's hurricane door assemblies carry Florida certifications FL21194 and FL46851. These approvals were achieved through testing by De La Fontaine and cover both HVHZ and non-HVHZ applications.

What is the difference between HVHZ and non-HVHZ requirements?

HVHZ (High-Velocity Hurricane Zones, primarily Miami-Dade and Broward Counties) requires testing to TAS 201, TAS 202, and TAS 203 standards plus a Miami-Dade Notice of Acceptance. Non-HVHZ areas require FBC approval with ASTM E1886 and E1996 testing.

What are the design pressure ratings for CDF's hurricane doors?

CDF's hurricane door assemblies are rated at +/-65 PSF and +65/-53.3 PSF, depending on configuration and size. The door uses 18 gauge galvanneal steel and the frame uses 16 gauge galvanneal steel, factory primed gray.

Can I substitute hardware on a hurricane-rated door assembly?

No. All hardware must match the tested configuration documented in the Florida Product Approval. Substituting hardware not included in the tested assembly voids the product approval and will result in a failed inspection.

What documentation is needed for hurricane door inspection?

Prepare the Florida Product Approval documentation with the approval number, product labels on the door and frame, the approved installation instructions, and verification that the anchor pattern and hardware match the approved configuration. CDF ships this documentation with hurricane door orders.

Configure Your Door Assembly

Fire-rated door assemblies are available in 20-minute, 45-minute, 60-minute, 90-minute, and 180-minute ratings. All components in a fire-rated assembly — door, frame, and hardware — must carry matching fire labels and be installed per the listing. Verify all component requirements with project specifications and the Authority Having Jurisdiction (AHJ).

A Note on Fire-Rated Assemblies

CDF is one of a limited number of distributors that stocks Florida-certified hurricane-rated hollow metal door assemblies. CDF's hurricane doors carry Florida certifications FL21194 and FL46851, tested and approved through De La Fontaine.

When contractors order hurricane door assemblies through CDF's ProBuilder tool, ProBuilder ensures the selected configuration matches an approved Florida Product Approval. CDF ships the assembly with the required product labels, Florida approval documentation, and installation instructions — giving contractors the documentation they need to pass building department inspection.

How CDF Supports Hurricane Door Installation

Some projects require door assemblies that carry both hurricane ratings and fire ratings. Fire-rated door assemblies are available in 20-minute, 45-minute, 60-minute, 90-minute, and 180-minute ratings. When both ratings are required, every component must satisfy both the Florida Product Approval and the fire test listing simultaneously.

Coordinate dual-rated assemblies carefully during the specification and ordering phase. The hardware, anchoring, and installation requirements for the hurricane approval and the fire listing must both be met without conflict. CDF's ProBuilder tool helps identify configurations that satisfy both requirements.

Fire-Rated Hurricane Door Assemblies

Hurricane-rated door installations in Florida are subject to building department inspection. Prepare the following documentation and conditions for the inspector.

• Florida Product Approval documentation showing the approval number (FL21194 or FL46851) and the approved configuration details.

• Product labels on the door and frame showing the manufacturer, Florida approval number, and design pressure rating.

• Installation instructions from the product approval, available on-site for the inspector's review.

• Anchor pattern verification — the inspector will check anchor type, spacing, and embedment against the product approval requirements.

• Hardware verification — the inspector may verify that installed hardware matches the approved configuration.

• Ensure the door operates correctly: self-closing, positive latching, and proper clearances.

Failed inspections most commonly result from incorrect anchoring patterns, missing product approval documentation, or hardware that does not match the tested assembly. Having all documentation on-site and following the approved installation instructions exactly prevents these issues.

Inspection Preparation

Hurricane-rated door assemblies must be installed exactly per the Florida Product Approval installation instructions. Deviating from the approved installation method voids the product approval and may result in failed inspections.

Frame Anchoring

• Anchor type, size, spacing, and embedment depth must match the product approval's installation instructions exactly.

• Typical anchoring uses through-frame fasteners into the surrounding wall construction at specified maximum spacing.

• The anchor pattern may vary depending on the wall construction type (masonry, concrete, steel stud, wood stud).

Shimming and Grouting

• Shim the frame plumb and square before anchoring. Use non-compressible shims at anchor locations.

• Grout hollow metal frames per the product approval requirements. Some approvals require full grouting of frame cavities.

Hardware Installation

• All hardware must match the tested configuration in the product approval. Substituting hardware not included in the tested assembly voids the approval.

• Hinge quantity, type, and fastener specifications must match the approval.

• Lock, closer, and weatherstripping must be installed per the approved configuration.

Sealant and Weatherstripping

• Apply perimeter sealant between the frame and rough opening as specified in the product approval.

• Install all weatherstripping and gasketing included in the approved assembly. Missing weatherstripping can cause water infiltration test failures.

Installation Requirements

Hurricane door assemblies undergo a series of standardized tests to achieve Florida approval. Understanding these tests helps contractors verify that installed assemblies match the approved configuration.

TAS Testing (HVHZ)

• TAS 201 (Impact Test): Large and small missile impact testing. A large missile test fires a 2x4 lumber section at the assembly at specified velocity. A small missile test fires steel ball bearings at the assembly.

• TAS 202 (Uniform Static Air Pressure Test): Tests the assembly's structural capacity under positive and negative static air pressure loads.

• TAS 203 (Cyclic Pressure Test): Applies thousands of pressure cycles at increasing intensities to simulate sustained hurricane wind conditions.

ASTM Testing (Non-HVHZ)

• ASTM E1886: Standard test method for performance of exterior windows, curtain walls, doors, and impact protective systems impacted by missile(s) and exposed to cyclic pressure differentials.

• ASTM E1996: Standard specification for performance of exterior windows, curtain walls, doors, and impact protective systems impacted by windborne debris in hurricanes.

CDF's hurricane door assemblies have been tested to both TAS and ASTM standards, providing coverage for both HVHZ and non-HVHZ applications across Florida.

Testing Standards for Hurricane Doors

Design pressure (DP) ratings define the wind load a door assembly can withstand. The required DP rating depends on the building's location, height, exposure category, and the specific opening's position on the building envelope.

CDF Hurricane Door Specifications

• Door construction: 18 gauge galvanneal steel door.

• Frame construction: 16 gauge galvanneal steel frame.

• Finish: Factory primed gray, ready for field paint.

• Design pressure ratings: +/-65 PSF and +65/-53.3 PSF, depending on configuration and size.

The positive pressure rating indicates resistance to inward wind pressure (wind pushing on the door). The negative pressure rating indicates resistance to outward wind suction (wind pulling the door outward). Both ratings must meet or exceed the project's calculated design pressure requirements.

How to Determine Required Design Pressure

The structural engineer of record calculates the required design pressure for each opening based on ASCE 7 wind load provisions, the building's risk category, exposure category, and the opening's location on the building. The door assembly's tested DP rating must meet or exceed this calculated requirement.

Design Pressure Ratings

The Florida Building Code (FBC) establishes specific requirements for exterior door assemblies in wind-borne debris regions. Hurricane-rated doors must meet design pressure ratings, impact resistance standards, and installation procedures defined by the FBC and the product's Florida approval.

Florida approval numbers certify that a product has been tested and approved for use under the FBC. CDF's hurricane door assemblies carry Florida certifications FL21194 and FL46851, achieved through testing by De La Fontaine, a recognized Florida product approval testing laboratory.

HVHZ vs. Non-HVHZ Zones

Florida designates certain coastal areas as High-Velocity Hurricane Zones (HVHZ), primarily Miami-Dade and Broward Counties. HVHZ zones have stricter testing and approval requirements than the rest of the state.

• HVHZ (Miami-Dade and Broward Counties): Products must meet Miami-Dade Notice of Acceptance (NOA) requirements in addition to FBC approval. Testing protocols include TAS 201, TAS 202, and TAS 203 for impact and cyclic pressure.

• Non-HVHZ (remainder of Florida): Products must meet FBC approval requirements and ASTM testing standards for the specified design pressure and impact resistance.
