How to Tell If Your Windows Are Hurricane-Rated in Fort Lauderdale

You bought a home in Fort Lauderdale, and the previous owner said it had "hurricane windows." The frames look strong, the glass feels thick, and the windows close firmly. But how can you confirm what is actually installed?

The most reliable approach is to identify the manufacturer and exact window model, match them to product-approval documents, and review the installation records. Appearance alone cannot establish hurricane protection.

This matters whether you own a single-family home, manage rental properties, or operate a business. One replacement window may differ from the others, and a new-looking sliding door may not have the same rating as the windows beside it.

This guide explains how to tell if windows are hurricane-rated, what information to collect, and when to ask a professional for help.

What Does "Hurricane-Rated" Actually Mean?

"Hurricane-rated" is a common marketing phrase, but it is not enough information to identify a window's performance.

There are two important questions:

• Is the window assembly rated to withstand the required wind pressures?
• Is that assembly also rated for windborne-debris impact?

Do not treat those questions as interchangeable. A window can have a wind-pressure rating without being an impact-resistant product.

You also need to consider the complete assembly - not just the glass. The frame, hardware, anchoring, installation details, and surrounding opening all matter.

When reviewing paperwork, look for information about the specific product and configuration. A broad statement such as "storm windows installed" does not tell you which model was used or whether it matches the requirements for your property.

Start by Checking Each Window Separately

Avoid assuming every window in the building was installed at the same time.

A previous owner may have replaced front-facing windows while leaving bedroom windows unchanged. An enclosed patio may contain different products from the original house. A broken pane may also have been replaced later.

Create a simple record for each opening. Give it an easy name, such as "front living room left" or "rear bedroom."

Photograph the complete window, any readable labels, and any markings on the glass. Record the location alongside each photograph so you can match the information later.

Include exterior glazed doors in your review. Identifying the windows alone does not establish the protection provided by the rest of the building's openings.

Look for Manufacturer Labels and Identification Numbers

Begin with a safe visual check of accessible frame and sash surfaces. Label locations vary by manufacturer and window design.

Open the window only if it operates normally and you can do so safely. Do not remove glazing, dismantle frames, or climb outside to search for a label.

Useful information may include:

• Manufacturer name
• Model or series number
• Serial or order number
• Product-approval reference
• Performance or certification information
• Manufacturing date

For impact window identification, clear photographs are often more useful than a handwritten description. Small differences between model numbers can matter.

If a label is damaged, photograph the readable parts rather than guessing the missing characters. The manufacturer may be able to help identify the product from the remaining information.

A missing label does not automatically mean the window is non-impact. It means you need another way to verify it.

Understand What Glass Markings Can - and Cannot - Prove

You may find a small permanent marking near a corner of the glass. This can provide useful identification, but it should not be treated as a complete hurricane certification by itself.

In particular, a marking that identifies tempered safety glass does not, on its own, establish that the window assembly is impact-rated.

The same caution applies to descriptions such as double-pane, tinted, insulated, or energy-efficient. Those terms describe other characteristics, not proof of windborne-debris resistance.

When you locate a glass marking, record it alongside the window's frame label. Ask the manufacturer or an appropriately qualified professional to explain what each identifier establishes.

The goal is to connect the installed product to documentation - not to decide its rating from one unfamiliar abbreviation.

Verify the Exact Product Through Official Records

Once you have identifying information, look for the corresponding approval documents.

The Florida Product Approval search provides an official starting point for researching approved products. Miami-Dade County also maintains a Product Control search for its product approvals.

These are lookup resources, not automatic confirmation that a particular installed window is suitable for your building.

Use the documents to check whether the manufacturer, series, product type, and relevant configuration match your records. If the result appears to describe a different window, do not assume it is close enough.

A manufacturer's name alone is insufficient. One company may offer multiple product lines with different performance characteristics.

Save the relevant documents with your photographs and installation paperwork. If the matching process is unclear, ask for help before relying on the result.

Why a Product-Approval Number Is Only Part of the Answer

Finding an approval number is useful, but it does not complete the assessment.

The product must match the approved configuration, and its installation must be appropriate for the opening and property. A photograph cannot reveal every concealed anchor or installation detail.

Likewise, a document for one window size or configuration should not automatically be applied to every unit that looks similar.

Ask a professional to explain what has been verified, what remains uncertain, and whether additional records or inspection are needed.

This is especially important when documents are incomplete, products have been altered, or the building contains windows from several installation periods.

Ask for the Original Installation Paperwork

Paperwork can answer questions that a visual inspection cannot.

Start with the previous owner, original installer, property manager, or condominium association. Ask whether they have the signed contract, itemized invoice, window schedule, product approvals, or inspection records.

An invoice that names the exact model and opening locations is more useful than one that simply says "replace windows."

You can also ask the building department responsible for your address what permit and inspection records are available. Explain that you are trying to identify previously installed windows.

Keep in mind that a record showing work occurred is not necessarily a complete description of the products currently present. Later repairs or replacements may need separate documentation.

Compare records with the actual windows rather than assuming the paperwork covers every opening.

Use This Hurricane Window Verification Checklist

Organizing your findings makes the next conversation with a contractor or manufacturer much easier.

• List every opening. Include windows, sliding glass doors, and other exterior glazed doors.
• Take clear photographs. Capture the entire unit and readable identification details.
• Record model information accurately. Do not substitute a similar-looking series number.
• Collect installation records. Request invoices, product schedules, and available inspection documents.
• Check official approval resources. Match the specific product rather than the brand alone.
• Identify uncertainties. Mark openings with missing labels, conflicting paperwork, or later repairs.
• Note visible defects. Record cracks, loose components, corrosion, or operating problems.
• Request a professional review where needed. Ask what can be confirmed and what requires further investigation.

Do not remove labels while cleaning. They may be valuable for future servicing, replacement parts, or product identification.

Avoid These Unreliable Home Tests

There is no dependable shortcut based only on how a window looks or sounds.

Knocking on the glass, comparing reflections, or judging its thickness cannot establish the approval of the complete window assembly.

Other assumptions to avoid include:

"The house is newer, so the windows must be impact-rated."

The building's age does not identify every product currently installed.

"The windows survived a previous storm."

Past survival does not verify a particular tested rating or predict future performance.

"The glass has a safety marking."

A safety-glazing marking is not, by itself, proof of hurricane-impact performance.

"There are shutters outside, so the windows must also be impact-resistant."

Shutters and windows should be identified separately.

Never strike a window with a tool or object to test it. A destructive experiment can cause injury, damage the product, and still fail to establish its certified performance.

Check Condition as Well as Identification

Knowing the original product rating does not answer every question about its present condition.

Look for visible damage without dismantling the assembly. Note cracked glass, loose frames, damaged hardware, significant corrosion, or windows that no longer close and lock correctly.

These observations are reasons to seek assessment - not enough information to diagnose the repair yourself.

For example, an operating problem may involve hardware, alignment, or another issue. Replacing the entire window should not be assumed necessary before the cause is evaluated.

Tell the professional about any previous glass replacement or repair. Ask whether replacement components match the original product specifications and whether supporting records are available.

When Should You Discuss Window Replacement?

An unidentified window does not automatically need replacement. First, determine whether records or manufacturer assistance can resolve the uncertainty.

Replacement becomes a useful discussion when existing products do not meet your goals, damage cannot be appropriately repaired, or an assessment identifies a need for an upgrade.

Before requesting estimates, prepare your opening list, photographs, and available documents. Explain whether your priorities include storm protection, easier operation, noise reduction, or replacing deteriorated units.

For local replacement options, explore impact windows and doors in Fort Lauderdale.

Ask the contractor to explain the proposed products and documentation in plain language. You should understand what is being quoted before approving the work.

What Fort Lauderdale Property Owners Should Ask

If you are comparing hurricane windows in Fort Lauderdale, focus on specific answers rather than broad protection claims.

Ask:

1. Which exact manufacturer, model, and configuration are included?

2. What documentation supports the proposed product's impact performance?

3. How will suitability for my property be established?

4. What installation and approval steps are included?

5. Which records will I receive when the work is complete?

6. Are there any openings excluded from the proposal?

Property owners outside the city can review Visions to Reality's Broward County service coverage when arranging a replacement consultation.

For an association-managed property, involve the property manager early. Ask what records already exist and what approval process applies before choosing replacement products.

Get Clear Answers Before Planning an Upgrade

Identifying your existing windows starts with evidence: readable labels, matching product documents, and installation records. If something is missing, record the uncertainty and get help resolving it rather than assuming the opening is protected.
