Impact Windows and Doors - Broward County Installer
NOA-Approved Impact Windows Permitted and Installed Across Broward County
Every product verified for Florida Product Approval compliance before the permit application is submitted.
What NOA Approval Means and Why Broward County Permits Require It
A Notice of Acceptance — NOA — is a product certification that tells Broward County a window can survive South Florida wind and impact conditions.
The NOA is issued by Miami-Dade County’s product control division. It’s the most rigorous window and door certification in the state. Broward County’s building permit application requires an NOA number on every impact product before the permit moves to plan review.
The number doesn’t just confirm wind resistance. It certifies that the specific product — that manufacturer, that model, that glass configuration — passed a defined test protocol for both wind pressure and debris impact. Two products can both be called “impact windows.” Only one may carry a valid NOA.
Every impact window and door installed by NVN Construction is verified against Broward County’s Florida Product Approval system before a permit application is submitted. Florida Product Approval is the statewide certification system that ensures building products meet Florida Building Code performance standards. The NOA satisfies both — it clears Miami-Dade and Broward requirements simultaneously. That verification step happens before ordering. Not during plan review. Not after a rejection.
As a licensed general contractor for permitted installations, NVN submits complete NOA documentation with every permit application, ensuring compliance is confirmed before the application enters plan review. For a full overview of the steps involved, see our guide to the Broward County permit process for window installations.

Coastal Broward vs. Inland Broward: Why Design Pressure Ratings Differ by Neighborhood
Eastern Broward homes require higher Design Pressure ratings than homes further inland — and the permit reflects that difference.
Design Pressure rating, or DP rating, is the numerical measure of how much wind force a window or door is certified to withstand. Florida’s Building Code wind speed map assigns minimum DP requirements based on a property’s location. Homes closer to the Atlantic coast fall into higher wind exposure zones. A window product that clears the minimum spec in Tamarac may not meet the required DP rating for a home in Pompano Beach or Dania Beach.
This distinction matters before you order a single unit. NVN identifies the correct wind exposure zone for your Broward County address before any product is selected. The DP rating on every window we install is matched to the wind zone your property sits in — coastal or inland. That determination is part of the permit documentation, not a detail resolved at inspection. For a broader look at how wind exposure zones affect your overall storm readiness, see our guide to hurricane season preparation for Broward homes.

Single-Pane Windows Behind Shutters - and Why That Cycle Ends with Impact Glass
You pull the shutters out every June. You put them back in storage every December. The windows behind them haven’t changed.
That’s a common Broward routine. Accordions or panels provide the opening protection the code requires. But the windows themselves — single-pane or standard double-pane — offer no structural protection on their own. The shutters are doing the work. If you’ve been weighing whether to continue that cycle or upgrade, our breakdown of impact windows vs. storm shutters in South Florida covers the structural and compliance differences in detail.
Project: Pompano Beach
NVN recently completed an impact window installation for a Pompano Beach homeowner who had run that same shutter cycle for eleven years. Single-pane units throughout. Every spring, a weekend installing accordions. Every fall, storing them. The windows had no Florida Product Approval number, no DP rating, no place on any wind mitigation report.
Every opening was replaced with laminated impact glass — two panes bonded to a plastic interlayer that holds the glass in the frame when struck rather than shattering. The permit was filed under CGC1539896 with the NOA number documented for each unit. The homeowner submitted the wind mitigation report to their insurance carrier the following month.
Impact glass changes the structure of the opening itself. The shutter was always external to the window. Impact glass is the window.
Every Product We Install Carries a Florida Product Approval Number Before the Permit Is Filed
NVN verifies Florida Product Approval compliance on every impact window and door before the permit application is submitted – not after.
Florida Product Approval is the statewide system that certifies building products meet Florida Building Code performance requirements. The NOA number – issued by Miami-Dade County – satisfies the Broward County permit requirement for the High-Velocity Hurricane Zone, or HVHZ. Broward County and Miami-Dade County share HVHZ status. Products tested only to standard Florida Product Approval may not meet the stricter HVHZ threshold. That gap shows up during plan review.
Before any product is ordered, the manufacturer’s model number is cross-referenced against Broward County’s approved product list. The NOA number is confirmed active and applicable to the installation configuration – size, anchorage method, and installation type. That documentation is included in the permit application package submitted through Broward County’s ePermits portal.
A rejected permit application delays the entire project. It also delays insurance mitigation documentation. The compliance check runs first so neither outcome applies to your project.
How We Verify DP Rating Against Your Broward County Wind Zone Before Ordering
NVN matches every window and door to the minimum DP rating your Broward County address requires — before a product is selected.
Our standards on every impact window and door project:
01
Wind zone confirmation.
We identify your property’s wind exposure category using Florida’s Building Code wind speed map before any product discussion begins.
02
DP rating minimum.
The design pressure rating on every unit meets or exceeds the code minimum for your specific Broward County location — coastal zone properties receive higher-rated units than inland addresses require.
03
NOA cross-reference.
Every product is verified against the active NOA database before it’s ordered. If a product has been updated or a certification has lapsed, we catch it at this stage.
04
Buck frame specification.
The buck frame — the structural frame anchored into the rough opening that transfers wind load from the window into the wall structure — is sized and anchored per the manufacturer’s NOA installation instructions, not a generic standard.
05
Laminated glass configuration.
We install laminated impact glass in every unit. Two glass panes bonded to a plastic interlayer. When struck, the glass cracks but stays seated in the frame. No shards. No open opening.
06
Insurance mitigation documentation.
Wind mitigation documentation for your insurance carrier is prepared as part of the installation record — not a separate request after the job is done.
Buck Frame, Laminated Glass, and Final Inspection: The Broward Impact Window Installation Sequence
Every NVN impact window installation in Broward County follows the same permitted sequence – from product verification to Certificate of Completion
PHASE 01
Diagnostics
The process begins with a physical site assessment. NVN measures every opening, identifies existing frame conditions, and checks the rough opening structure. For homes with older masonry construction — common throughout Broward County’s mid-century housing stock — the masonry opening condition determines buck frame depth and anchor spacing. Existing window types are documented and any opening-specific NOA exclusions are confirmed before products are specified.
The permit history for the property is pulled from Broward County’s public permit portal. Prior window permits, open permits, or code violations are identified before the new application is filed. That record influences the scope and, in some cases, the product selection.
PHASE 02
Implementation
The permit is submitted through Broward County’s ePermits portal under CGC license number CGC1539896. The NOA number for each product is included in the permit documents. After permit approval, existing windows and doors are removed. The rough opening is inspected before the buck frame is set. Buck frames are anchored into the structural substrate — masonry or wood frame — per the NOA installation specification. The laminated impact glass units are set into the buck frame and sealed.
From a Broward County permit inspector’s checklist perspective, this is what gets checked: Is the product on the permit the same product installed? Does the NOA number match the submitted documentation? Is the buck frame anchored correctly for the opening size and wind zone? Is the installation method consistent with the manufacturer’s NOA instructions? Every one of those questions is answered before the inspector arrives.
PHASE 03
Post-Service Testing and Documentation
After installation, every unit is tested for operation, seal integrity, and hardware function. The wind mitigation documentation — identifying each opening, the product installed, and its NOA status — is compiled and delivered to the homeowner. This is the document an insurance carrier uses during a wind mitigation inspection to determine eligibility for an insurance mitigation credit, which is a reduction in homeowner’s insurance premiums awarded when a home has qualifying hurricane protection.
The Certificate of Completion from Broward County Building Services is the final deliverable. It’s the official record that the permitted installation passed inspection and was completed to code. It becomes part of the property’s permanent permit history. For a homeowner planning to sell, refinance, or submit an insurance claim, that record has direct value.
Impact Window and Door Installations Completed Across Broward County
NVN installs impact windows and doors throughout Broward County under Florida CGC license #CGC1539896.
We serve the full county – from coastal communities in Pompano Beach, Deerfield Beach, and Hallandale Beach, where higher wind exposure categories require elevated DP ratings, to inland areas including Coral Springs, Tamarac, Plantation, and Davie. We also work in Hollywood, Miramar, Pembroke Pines, and Dania Beach. Older housing stock in many of these neighborhoods – particularly homes built before Broward County adopted HVHZ product standards – is where single-pane and non-impact double-pane units are most commonly found. Every project in these areas is permitted through Broward County Building Services.

How much do impact windows cost to install in Broward County?
Impact window installation in Broward County typically runs $800-$1,200 per opening for standard residential sizes, before permit fees. Coastal properties require higher Design Pressure-rated units, which carry a material cost premium over inland-spec products. Labor costs in South Florida run above the national median, and NOA-approved products cost more than standard windows sold elsewhere. Permit fees are calculated on project valuation through Broward County Building Services, adding a variable soft cost that national price guides don’t reflect.
How long does an impact window permit take to get approved in Broward County?
Standard residential impact window permits in Broward County typically take two to four weeks from submission to approval. Timeline varies by municipality – Coral Springs and Pembroke Pines run their own plan review alongside county Building Services. Including NOA verification, permit submission, installation, and final inspection, most projects complete in four to eight weeks total. Projects initiated in spring compete with pre-hurricane-season permit volume, which extends that range.
Can a homeowner install impact windows themselves in Florida?
No – impact window installation requires a licensed contractor to pull the permit in Broward County. Florida’s owner-builder exemption does not cover impact window replacements that require opening protection compliance under the Florida Building Code. An unlicensed installation cannot be inspected, does not satisfy the wind mitigation documentation requirement, and voids insurance mitigation credit eligibility. The CGC license held by NVN Construction – #CGC1539896 – is the credential that authorizes permit submission for this work.
How much can impact windows actually lower my homeowners insurance premium?
Premium reductions vary by carrier and policy, but wind mitigation credits for fully impact-rated openings commonly reduce the wind portion of a Florida homeowner’s premium by 20-45%. The exact figure depends on the insurance carrier, current premium structure, and wind mitigation inspection score. The documentation NVN prepares at project close – listing each opening, product, and NOA number – is what the inspector uses to score the home. Without that record, the credit cannot be calculated or applied.
Do impact windows come with a warranty, and who handles it if a unit fails?
Impact windows carry two separate warranties – a manufacturer’s product warranty on the glass unit and frame, and a workmanship warranty on the installation. Manufacturer warranties on NOA-approved products typically run 10-20 years. Installation defects – such as improper buck frame anchoring – fall under the contractor’s workmanship warranty. NVN Construction’s CGC license #CGC1539896 creates a permanent contractor-of-record record with Broward County Building Services for every permitted installation.
Can existing window frames be kept when upgrading to impact glass?
Existing frames can sometimes be retained using an insert installation method, but only if the frame is structurally sound and the opening size after insertion meets the minimum required for the replacement unit’s NOA approval. Insert installations require the existing frame to pass a condition assessment before any product is specified. In Broward County’s older masonry housing stock, frame deterioration and non-standard opening sizes frequently make full replacement – including a new buck frame – the only code-compliant option.
If I install impact windows, do I still need to keep my accordion shutters?
NOA-approved impact windows satisfy Broward County’s opening protection requirement for every covered opening – shutters are no longer required on those openings. If every window and door is replaced with impact-rated units, accordion shutters are not needed for code or insurance compliance. Existing shutters can be removed or left in place. The wind mitigation report submitted to the insurance carrier documents the shift from shutter-based to glass-based opening protection, which affects how the home scores.
What actually happens to impact glass when it gets hit during a storm?
Laminated impact glass cracks on impact but stays seated in the frame – the plastic interlayer bonded between the two glass panes holds the broken glass in place. The opening remains sealed even after a direct strike. This is the core functional difference from standard glass, which shatters and creates an open breach in the building envelope. After a storm, a cracked impact unit must be replaced, but it does not fail the way standard glazing does during the event.
