Impact Windows & South Florida New Construction: What Palm Beach and Broward Builders Won't Tell You
Building a new home in South Florida is one of the most significant investments you will ever make. From choosing your lot in Wellington or Weston to selecting finishes in Delray Beach or Coral Springs, every decision carries long-term financial and safety implications. Yet one of the most critical components of your new home - the windows and doors - is often treated as an afterthought in builder contracts.
If you are currently working with a production builder or a custom home contractor in Palm Beach County or Broward County, there is a good chance important details about your impact window package have been glossed over. This guide is here to change that.
Why Impact Windows Are Non-Negotiable in New South Florida Construction
Florida's building code has long mandated wind-resistant openings for new residential construction in high-velocity hurricane zones, which covers essentially all of Palm Beach and Broward counties. The Florida Building Code (FBC), updated in 2023 and now fully implemented in 2024, requires that all glazed openings in new construction within the High-Velocity Hurricane Zone (HVHZ) meet rigorous impact-resistance or protection standards.
In plain language: your new home must either have impact windows and doors or a combination of standard windows paired with an approved hurricane protection system like accordion shutters or panel systems.
But here is what most builders in the region do not explain clearly: the minimum code-compliant option and the best option for your family are often very different things.
The HVHZ and What It Means for New Builds
The High-Velocity Hurricane Zone designation applies to Miami-Dade and Broward counties by name, but the Florida Building Code also applies equivalent wind load and impact requirements to Palm Beach County and all coastal communities. Any new home built in these areas must pass product approval testing that meets Miami-Dade Notice of Acceptance (NOA) standards or Florida Product Approval standards.
This is not optional. It is not a premium upgrade. It is the baseline.
What varies dramatically is the quality of the impact windows specified in your builder's base package.
What Builders Include vs. What You Actually Need
Production builders in communities from Boca Raton to Pembroke Pines operate on tight margins. Every dollar saved in materials goes directly to profit. That means the impact windows in your base package are almost always the least expensive product that meets minimum code requirements.
Here is what that typically looks like:
The Base Package Reality
- Single-pane laminated glass - Meets code but offers minimal thermal or acoustic performance
- Aluminum frames with standard finishes - May corrode faster in coastal salt air environments
- Minimal SHGC ratings - Solar Heat Gain Coefficients that barely scrape by Florida energy code minimums
- Standard Low-E coatings or none at all - Leaving your home vulnerable to heat gain and UV damage
- Builder-grade hardware - Less durable, less secure, and harder to replace long-term
If your new home is near the water in areas like Lake Worth Beach, Lauderdale-by-the-Sea, or Deerfield Beach, the difference between builder-grade aluminum frames and marine-grade or thermally broken aluminum frames becomes especially important. You can learn more about this in our guide on impact windows and salt air corrosion for coastal Florida homes.
What a Meaningful Upgrade Looks Like
A properly specified new construction impact window package from a top-tier manufacturer should include:
- Insulating glass units (IGU) - Double-pane laminated glass that dramatically reduces heat transfer
- Low-E coatings optimized for South Florida's solar exposure - Critical in a climate where cooling costs dominate energy bills
- Thermally broken frames - Especially important near the coast or in western communities like Boynton Beach or Miramar where summer heat is relentless
- SHGC values of 0.25 or lower - Aligned with Florida Energy Code maximums for conditioned spaces
- Quality hardware from brands like PGT, CGI, or ES Windows - Products we carry and stand behind at Window Guys of Florida
The energy savings alone from upgrading your glass package can offset a significant portion of the upgrade cost within just a few years of ownership.
The Builder Disclosure Gap: What They Are Not Required to Tell You
Builders are legally required to disclose the product specification they are using. What they are not required to do is explain the full range of options available to you, the performance differences between products, or the long-term financial implications of choosing the base package.
Here are five things Palm Beach and Broward builders frequently leave out of the conversation:
1. You Can Often Substitute Your Own Contractor
Many new construction contracts in Florida allow the buyer to use a licensed, insured specialty contractor for specific trades - including windows - as a credit or substitution. This is more common with custom builds, but even some production builders in communities like Palm Beach Gardens, Coral Springs, or Plantation will allow it during the pre-construction phase.
Asking for a window allowance or substitution credit and then hiring a dedicated impact window specialist like Window Guys of Florida can get you significantly better products at a comparable or lower total cost.
2. Builder Warranty Doesn't Cover Long-Term Product Performance
A builder's structural warranty covers defects in installation, not the long-term performance of the window product itself. Glass seal failures, frame delamination, and hardware degradation are product warranty issues - and builder-grade products often come with minimal manufacturer support.
Brands like PGT, CGI, and Andersen, which Window Guys of Florida installs as authorized dealers, carry manufacturer warranties that are transferable and provide meaningful long-term protection.
3. Impact Windows Affect Your Insurance Premium Significantly
Florida homeowners insurance is in a well-documented crisis. Premiums in Palm Beach and Broward counties have increased dramatically in recent years. What many new construction buyers don't realize is that the quality of your impact window package - not just whether you have impact windows - can affect your wind mitigation rating and, by extension, your insurance discount.
A comprehensive wind mitigation inspection after construction will document your opening protection. Higher-rated systems can yield larger discounts. Our detailed guide on impact windows and home insurance discounts in Florida explains exactly how this works and what to look for.
4. Impact Doors Matter Just as Much as Windows
Builders often put their lowest-cost effort into impact doors, particularly secondary entries, garage access doors, and sliding glass doors. A sliding glass door leading to your pool deck in Boynton Beach or a French door entry in Davie that barely meets code is not the same as a properly specified impact door with multi-point locking, reinforced frames, and quality laminated glass.
For families building homes with outdoor living areas or pool spaces, our guide on impact windows for South Florida pool homes provides specific guidance on what to look for in the builder's sliding door and terrace door specifications.
5. The Upgrade Timeline Is Limited
Once framing begins, your window rough openings are set. Once drywall goes in, changing window sizes or configurations becomes extremely costly. The window in a new construction project must be decided before or very early in framing - meaning buyers who delay the upgrade conversation often lose the opportunity entirely.
If you are currently in pre-construction or early construction on a home anywhere in our service areas across Palm Beach or Broward counties, now is the time to have this conversation.
Impact Windows vs. Hurricane Shutters in New Construction: The Builder's Favorite Workaround
Some builders, particularly in communities where land costs are lower and buyers are more price-sensitive, will spec standard windows with accordion shutters as the code-compliant hurricane protection system. This is legal. It is also, in many cases, a false economy.
The Real Cost Comparison
Accordion shutters on a new construction home in the 2,500 to 3,500 square foot range can cost $15,000 to $30,000 or more. Add that to the cost of standard windows, and you are often very close to the cost of a quality all-impact system - without any of the energy efficiency, noise reduction, UV protection, or security benefits that impact glass provides.
Furthermore, accordion shutters require manual deployment before storms. In the chaotic hours before a hurricane makes landfall in South Florida, that matters. Families who are traveling, elderly homeowners, or those with mobility challenges face real operational challenges with shutter-based systems.
For households with aging family members or multigenerational living arrangements, this operational burden is especially relevant. See our guides on impact windows for South Florida multigenerational homes and impact windows for senior homeowners in South Florida for more on this topic.
What Impact-Only New Construction Gives You
- 365-day protection - No deployment required, ever
- Energy efficiency year-round - Not just during storm season
- Noise reduction - Critical in communities near I-95, US-1, or flight paths
- UV protection - Protects flooring, furniture, and artwork from South Florida's intense sun
- Security - Smash-and-grab resistance that standard windows with shutters don't provide overnight
- Insurance discounts - Potentially larger than shutter-based systems depending on carrier
- Cleaner aesthetics - No tracks, accordion panels, or visual clutter on your new home's exterior
Navigating 2024 Florida Building Code Requirements
The 2023 Florida Building Code, 7th Edition, which is now the standard for new construction approvals across the state, has updated several provisions relevant to residential glazing:
Wind Load Requirements by Zone
New construction in Palm Beach and Broward counties must comply with wind speed maps that now reflect updated ASCE 7-22 standards. For most of coastal Palm Beach and Broward, design wind speeds range from 140 mph to 170 mph depending on exact location and proximity to the coast.
Impact windows and doors must be tested and rated to the specific design pressure (DP) required for your home's location, height, and exposure category. A window product approved for 140 mph in Boca Raton may not be appropriate for a three-story home on A1A in Palm Beach.
Energy Code Compliance
The 2023 FBC Energy Code requires that residential glazing meet maximum U-factor and SHGC values. For Climate Zone 1, which covers all of Palm Beach and Broward counties, the maximum allowable SHGC for fenestration is 0.25 without overhangs. Many builder-grade impact window units barely meet or occasionally fail this standard without documentation.
When reviewing your builder's window specs, ask specifically for the NFRC-certified performance data on every window and door product specified.
Flood Zone Considerations
New construction in flood zones - which cover large portions of both counties given South Florida's flat topography and coastal proximity - also involves window and door specifications that account for flood-resistant construction standards. Our in-depth guide on impact windows and flood zone compliance in Palm Beach and Broward covers this intersection in detail.
Choosing the Right Products for Your New Home
Window Guys of Florida is an authorized dealer for several of the most respected names in impact fenestration:
- PGT Innovations - Florida's largest impact window manufacturer, with a full line of residential products
- CGI Windows and Doors - Premium impact products with strong Miami-Dade NOA certifications

Special Use Cases in New Construction
The type of home you are building affects which impact window specifications matter most:
Investment and Rental Properties
If your new construction project is intended as a rental property or short-term rental, impact windows provide operational advantages that directly affect your returns. Guests do not have to manage shutters, and your property is protected year-round without property management involvement. See our guides on impact windows for South Florida rental properties and impact windows and short-term rental arbitrage in South Florida for more.
Home Offices and Businesses
With remote work increasingly common in communities like Boca Raton's tech corridor or Deerfield Beach's business parks, new homes being built with dedicated office space benefit from the noise reduction and climate stability that quality impact glass provides. Our guide on impact windows for South Florida home businesses covers deductibility and performance considerations.
Homes with Solar Integration
If your new construction includes or anticipates a solar panel system, window placement, shading, and SHGC values must be coordinated thoughtfully. Our guide on impact windows and solar panels in South Florida addresses this planning intersection.
Smart Home Integration
New construction is the ideal time to integrate motorized or sensor-linked impact window systems. Whether you are building a fully automated home in Palm Beach or a connected residence in Parkland, impact windows can be paired with smart home systems for lighting, ventilation, and security management. Explore our guides on smart home impact windows for Palm Beach and Broward and impact windows and smart security.
How to Protect Yourself During the New Construction Process
Here are actionable steps to take right now if you are building in Palm Beach or Broward County:
- Request the full product specification sheet for every window and door in your builder's base package - brand, model, series, glass type, frame material, and NFRC ratings
- Ask specifically about SHGC, U-factor, and DP ratings for each unit
- Inquire about substitution credits if you want to bring in a specialty contractor
- Get a quote from Window Guys of Florida before you finalize your contract - the comparison may surprise you
- Review the wind mitigation implications with your insurance agent before deciding between impact-only and shutter hybrid systems
- Ask whether the builder's warranty covers product performance or just installation defects

Frequently Asked Questions
Are impact windows required for all new construction in Palm Beach and Broward counties?
Yes, all new residential construction in Palm Beach and Broward counties must comply with Florida Building Code requirements for wind-resistant openings. In Broward County's High-Velocity Hurricane Zone designation, Miami-Dade NOA-certified products are required. Palm Beach County follows equivalent Florida Product Approval standards. This means either fully impact-rated windows and doors, or standard windows with an approved hurricane protection system such as accordion shutters. Most new construction professionals recommend an all-impact approach for maximum protection, energy efficiency, and insurance benefits. Learn more about our impact window options.
Can I replace my builder's impact windows with a different brand during construction?
In many cases, yes - but the timing is critical. Most substitutions must be made before framing is complete and rough openings are set. Some production builders in Palm Beach and Broward will allow a window allowance credit if you bring in a licensed specialty contractor. Custom home builders are generally more flexible. Contact Window Guys of Florida early in your construction process to discuss whether a substitution is possible and what it would cost. We have worked with numerous builders throughout the region on exactly this type of arrangement. Contact us for a free consultation.
What is the difference between builder-grade impact windows and premium impact windows in new construction?
Builder-grade impact windows meet minimum code requirements but typically use single-pane laminated glass, standard aluminum frames, and minimal Low-E coatings. Premium impact windows from brands like PGT, CGI, or ES Windows feature insulating glass units with double-pane laminated glass, thermally broken frames, advanced Low-E coatings, and lower SHGC values. The practical difference includes significantly better energy efficiency - often 20 to 35 percent lower cooling costs - meaningfully better noise reduction, greater UV protection, improved security ratings, and stronger manufacturer warranties. For coastal homes especially, frame quality also affects long-term durability against salt air exposure.
Do impact windows in new construction qualify for Florida homeowners insurance discounts?
Yes, impact-rated windows and doors in new construction can qualify for significant wind mitigation credits on your Florida homeowners insurance. The extent of the discount depends on your insurance carrier, the specific products installed, and the results of a post-construction wind mitigation inspection. Generally, an all-impact opening protection system earns larger credits than a hybrid system with shutters covering some openings. Given the current state of Florida's insurance market, these discounts can be substantial. Our guide on impact windows and home insurance discounts in Florida covers the wind mitigation inspection process in detail.
Should I choose impact windows or accordion shutters for my new South Florida home?
For most new construction homeowners in Palm Beach and Broward counties, an all-impact window and door system is the better choice. While accordion shutters with standard windows can meet code requirements, they require manual deployment before storms, provide no year-round energy or security benefits, and can add similar costs when properly compared to an impact system. Impact windows protect your home 365 days a year with no action required, reduce energy bills, cut noise, block UV rays, and provide continuous security. The only scenarios where a hybrid approach might make sense are specific architectural situations or tight construction budgets where cost differences are significant. Contact us for a side-by-side cost and performance comparison for your specific project.
How do I know if my builder's impact window specification meets 2024 Florida Building Code requirements?
Ask your builder to provide the full product approval documentation for every window and door specified - this should include the Florida Product Approval number or Miami-Dade NOA number, the tested design pressure (DP) rating, NFRC-certified energy performance data including U-factor and SHGC, and the glass configuration. Verify that the DP rating is appropriate for your home's location, height, and exposure category - a window rated for a single-story inland home may not be appropriate for a two-story coastal property on A1A. If you are unsure how to interpret this documentation, Window Guys of Florida can review it for you. Reach out to our team for a no-obligation specification review.
