Florida homeowners have more options than ever when replacing exterior doors with impact-resistant systems.
Impact front doors, French doors, and sliding glass doors can all provide hurricane protection when the complete door system is properly selected and installed for the application, but they serve very different purposes inside a home.
A front entry door may prioritize security, curb appeal, and privacy. French doors can create a wide, traditional opening between indoor and outdoor spaces. Sliding glass doors can maximize natural light and preserve views of pools, patios, lanais, and waterfront areas.
So which type of impact door is right for your Florida home?
This guide compares impact front doors, French doors, and sliding glass doors based on hurricane protection, appearance, space requirements, natural light, ventilation, security, maintenance, installation, and cost.
What Is an Impact Door?
An impact door is an exterior door system designed and tested for specified impact and wind-pressure conditions.
Depending on the product, the complete system can include:
- The door panel or panels
- Impact-resistant glass where applicable
- The frame
- Threshold
- Locks
- Hinges, rollers, or other operating hardware
- Anchoring components
- Weather seals
The entire system matters.
For example, placing impact-resistant glass into an ordinary exterior door does not automatically create an approved impact door system.
Why Florida Homeowners Choose Impact Doors
Exterior doors are major openings in a home's building envelope.
Florida homes can be exposed to hurricanes, tropical storms, high winds, windborne debris, heavy rain, intense sunlight, heat, and humidity.
Depending on the product, homeowners may choose impact doors for benefits involving:
- Permanent hurricane protection
- Protection against windborne debris
- Additional security
- Updated curb appeal
- Modern glass and frame options
- Improved everyday door operation
- Natural light
- Indoor-outdoor living
The exact benefits depend on the door system, installation, property, and products selected.
Are Impact Doors Hurricane-Proof?
No exterior door should be described as completely hurricane-proof.
The more accurate term is impact-resistant.
Impact door systems are designed and tested for specified conditions. Severe storms can exceed design conditions, and exterior building products can still experience damage.
Homeowners should focus on the specifications and approvals of the exact door system instead of relying on absolute marketing claims.
The Three Major Impact Door Options
For many Florida homes, exterior impact door projects fall into three broad categories:
- Impact front or entry doors
- Impact French doors
- Impact sliding glass doors
Each option can serve a different purpose.
The right choice depends largely on where the door is located and how you want that opening to function.
What Is an Impact Front Door?
An impact front door is an exterior entry system designed to provide impact resistance while serving as the home's primary entrance.
Impact entry doors can be available in many designs, including:
- Solid doors
- Doors with decorative glass
- Full-glass doors
- Single entry doors
- Double entry doors
- Doors with sidelites
- Doors with transoms
This makes the front door one of the most customizable impact upgrades on a home.
Advantages of Impact Front Doors
An impact front door may be a strong choice for homeowners prioritizing:
- Curb appeal
- Privacy
- Entry security
- Architectural style
- Permanent storm protection
- A defined main entrance
Because the front entrance is one of the first things visitors see, replacing an older door can also significantly change the appearance of the home.
Potential Considerations With Impact Front Doors
Before choosing an entry door, homeowners should consider:
- Existing opening dimensions
- Door swing
- Frame construction
- Amount of glass
- Desired privacy
- Hardware
- Exterior exposure
- Applicable product approval
A beautiful door still needs to be appropriate for the actual opening and project.
What Are Impact French Doors?
French doors generally consist of two hinged door panels that meet in the center.
Depending on the design, one or both panels may operate.
French doors are commonly used for:
- Patio entrances
- Pool areas
- Balconies
- Side entrances
- Primary entrances
- Connections between interior and outdoor living spaces
Impact-resistant French doors allow homeowners to maintain this traditional double-door appearance while incorporating hurricane protection into the door system.
Advantages of Impact French Doors
French doors may appeal to homeowners who want:
- A wide doorway
- A traditional or upscale appearance
- More glass than many solid entry doors
- Direct access to a patio or outdoor area
- Double-door functionality
- Permanent impact resistance
They can work particularly well in homes where the architecture already includes a hinged double-door opening.
Potential Considerations With French Doors
French doors require swing space.
Depending on the configuration, the panels may swing inward or outward, so homeowners need enough clear space around the opening.
Other considerations include:
- Furniture placement
- Patio space
- Door hardware
- Thresholds
- Weather sealing
- Panel alignment
- Opening dimensions
- Product approval
If space around the doorway is limited, a sliding door may provide a more practical alternative.
What Is an Impact Sliding Glass Door?
An impact sliding glass door uses one or more large glass panels that move horizontally along a track.
Sliding doors are extremely common in Florida because they can connect living rooms, kitchens, bedrooms, and other interior spaces with:
- Pools
- Patios
- Lanais
- Balconies
- Backyards
- Waterfront areas
Impact-resistant sliding glass doors combine large areas of glass with permanent impact protection.
Advantages of Impact Sliding Glass Doors
Impact sliders may appeal to homeowners who prioritize:
- Large outdoor views
- Natural light
- Indoor-outdoor living
- Large openings
- Space-saving operation
- Modern appearance
- Pool or patio access
Because the panels slide rather than swing, they do not require the same clearance as hinged French doors.
Potential Considerations With Sliding Glass Doors
Sliding glass doors contain several components that homeowners should evaluate carefully.
These can include:
- Tracks
- Rollers
- Locks
- Handles
- Glass configuration
- Frame material
- Threshold
- Panel configuration
- Drainage and weather-management features
Large sliding doors can also represent some of the largest exterior openings in the home, making accurate measurement and appropriate product selection especially important.
Impact Front Door vs. French Doors vs. Sliding Glass Door
The three door styles can be compared based on how homeowners plan to use the opening.
Impact Front Door
Often best suited for a primary entrance where curb appeal, privacy, security, and architectural design are major priorities.
Impact French Doors
Often best suited for homeowners who want a traditional double-door appearance and a wide hinged opening to a patio, pool, balcony, or entry area.
Impact Sliding Glass Doors
Often best suited for large openings where homeowners want maximum glass, natural light, outdoor views, and space-efficient operation.
Which Impact Door Provides the Most Natural Light?
Sliding glass doors generally provide the largest uninterrupted areas of glass.
This can make them appealing for homes overlooking:
- Pools
- Canals
- Waterfront areas
- Golf courses
- Gardens
- Patios
French doors with large glass panels can also provide substantial natural light.
Front doors vary considerably. A solid impact entry door may prioritize privacy, while a full-glass entry system with sidelites can introduce much more natural light.
Which Impact Door Provides the Most Privacy?
A solid or partially glazed impact front door can provide greater visual privacy than a large sliding glass door.
However, privacy depends on the specific glass and design.
Depending on the manufacturer, homeowners may have options involving:
- Clear glass
- Tinted glass
- Decorative glass
- Textured or privacy-oriented glass options
Verify available glass options for the exact product being considered.
Which Door Is Best for a Florida Patio?
Both French doors and sliding glass doors can work well for patios.
French doors may be preferred when homeowners want a traditional double-door appearance.
Sliding glass doors may be preferred when homeowners want a larger glass area and do not want door panels swinging into the patio or interior.
The right choice depends on the opening dimensions, available space, home architecture, and desired appearance.
Which Door Is Best for a Pool Area?
Sliding glass doors are common around Florida pools because they can provide broad views and convenient indoor-outdoor access.
French doors can also work well for pool areas, particularly when the homeowner prefers hinged double doors.
Homeowners should also consider applicable safety and code requirements for doors providing access to pool areas.
Which Door Is Best for a Waterfront Home?
Waterfront homeowners frequently want to preserve views.
Large impact sliding glass doors can be particularly attractive for canal, lake, Intracoastal, or ocean-facing areas because they provide substantial glass area.
French doors may work well where a smaller traditional opening is preferred.
Front entry doors typically serve a different purpose and may emphasize the street-facing appearance of the property instead.
Which Door Saves the Most Space?
Sliding glass doors generally require less operational floor space because the panels move horizontally along a track.
Hinged entry doors and French doors require clearance for the door panels to swing.
This can make sliders especially useful where furniture, patios, balconies, or other features limit available swing space.
Which Door Creates the Widest Opening?
The answer depends on the dimensions and configuration.
French doors can provide a wide opening when both panels are open.
Multi-panel sliding glass door systems can also create very large openings depending on the configuration.
Homeowners with unusually large openings should compare specific products rather than assuming one door type always provides more usable space.
Impact Doors and Home Security
Impact-resistant doors can provide an additional obstacle compared with some ordinary exterior doors and glass systems.
However, security depends on the complete assembly.
Important components can include:
- Door panel
- Impact-resistant glazing
- Frame
- Locks
- Hardware
- Anchoring
- Installation
No impact door should be described as impossible to breach.
Impact Doors and Outside Noise
Some impact door systems may reduce certain exterior sounds compared with older doors or ordinary glass systems.
Actual results depend on factors such as:
- Glass configuration
- Door construction
- Frame
- Weather seals
- Installation
- Surrounding walls and windows
- Type of exterior noise
No impact door should be expected to make a home completely soundproof.
Impact Doors and Energy Performance
Exterior doors can influence a home's overall energy performance.
Depending on the product, impact doors containing glass may be available with options such as:
- Low-E coatings
- Insulated glass configurations
- Tints
- Other manufacturer-specific glass packages
Homeowners should verify the exact glass and door specifications rather than relying solely on general "energy-efficient" marketing language.
Low-E Glass for Impact Doors
Low-emissivity, commonly called Low-E, coatings are designed to influence how certain types of energy pass through glass.
For Florida homes with significant sun exposure, glass selection can be an important consideration.
Not every impact door automatically includes the same Low-E package, so verify the exact configuration included in your proposal.
Vinyl vs. Aluminum Impact Sliding Glass Doors
Depending on the manufacturer and product line, impact sliding doors may be available with different frame materials.
When comparing options, consider:
- Opening dimensions
- Frame profile
- Architecture
- Available configurations
- Glass options
- Product approvals
- Maintenance
- Appearance
- Budget
Statewide Windows & Doors offers both vinyl and aluminum impact-product options, allowing homeowners to compare products based on the needs of their project.
Impact Door Product Approvals
Product approval is an important part of researching impact doors in Florida.
Depending on the product, approval documentation can contain information involving:
- Door type
- Approved configurations
- Maximum dimensions
- Glass specifications
- Design pressures
- Anchoring requirements
- Installation conditions
- Limitations of use
Ask the contractor to identify the exact door system included in the proposal.
Impact Doors in Miami-Dade and Broward County
Miami-Dade and Broward counties make up Florida's High-Velocity Hurricane Zone, commonly called the HVHZ.
For applicable projects within the HVHZ, the exact impact door and configuration should be approved for its intended application.
Homeowners should not assume that every impact-resistant door produced by a manufacturer is automatically approved for every HVHZ installation.
Miami-Dade NOA vs. Florida Product Approval for Doors
Homeowners may encounter both Miami-Dade Notices of Acceptance and Florida Product Approvals when researching impact doors.
A Miami-Dade NOA is one recognized product-approval pathway.
Qualifying Florida Product Approvals specifically approved for HVHZ use may also apply.
A generic Florida Product Approval should not automatically be interpreted as approval for every HVHZ application.
The important question is whether the specific door system and configuration is approved for the intended application.
Do Impact Doors Need Permits in Florida?
Exterior door replacement projects may require permitting through the applicable local building jurisdiction.
Requirements vary depending on the property, jurisdiction, door, and scope of work.
Permit documentation can involve:
- Permit applications
- Opening information
- Product approval documentation
- Door specifications
- Installation information
- Other project-specific documentation
Homeowners should determine how permitting will be handled before installation begins.
HOA Approval for Impact Doors
Homeowners associations may have architectural rules involving exterior doors.
Depending on the community, an HOA may review:
- Door color
- Door style
- Frame color
- Glass appearance
- Exterior hardware
- Product information
HOA approval and a government building permit are separate processes.
Can You Replace a Front Door Without Changing the Opening Size?
Many replacement projects use the existing opening, but this depends on the selected door and existing conditions.
If the homeowner wants to significantly enlarge, reduce, or otherwise modify an exterior opening, the project may involve additional considerations.
The contractor should evaluate the existing conditions before the final product is ordered.
Can French Doors Replace a Sliding Glass Door?
Potentially, but this is not necessarily a simple product swap.
Sliding glass doors and French doors operate differently and may require different framing, dimensions, thresholds, structural considerations, permitting, and finishing work.
A contractor should evaluate the opening before determining whether conversion is practical.
Can a Sliding Glass Door Replace French Doors?
Potentially.
Some homeowners consider converting hinged French doors into sliding glass doors to increase the amount of glass or eliminate swing-space requirements.
As with the reverse conversion, the existing opening, surrounding construction, product dimensions, approvals, and project requirements should be evaluated first.
How Much Do Impact Front Doors Cost?
There is no universal price for an impact front door.
Cost can vary based on:
- Door dimensions
- Single or double configuration
- Door material
- Amount of glass
- Decorative options
- Sidelites
- Transoms
- Hardware
- Existing opening conditions
- Installation complexity
- Permitting
- Finishing work
A property-specific quote provides more useful information than a generic online average.
How Much Do Impact French Doors Cost?
French door pricing can depend on:
- Opening dimensions
- Door configuration
- Glass package
- Frame
- Hardware
- Threshold
- Product approval
- Installation
- Permitting
- Finishing work
Compare the complete project scope rather than only the price of the door itself.
How Much Do Impact Sliding Glass Doors Cost?
Sliding glass door pricing can vary significantly because slider systems can range from relatively simple openings to very large multi-panel configurations.
Cost can depend on:
- Opening width and height
- Number of panels
- Frame material
- Glass package
- Track configuration
- Hardware
- Product approval
- Existing conditions
- Installation complexity
- Permitting
- Finishing work
Large custom configurations should be evaluated individually.
Which Impact Door Is the Most Affordable?
There is no door style that is automatically the least expensive in every situation.
A simple single entry door may cost less than a large multi-panel slider, but premium entry systems with decorative glass, sidelites, or double doors can also become substantial projects.
Compare actual proposals for your home's openings rather than relying on general assumptions about price.
What Happens During Impact Door Installation?
Although every project differs, installation may involve:
- Preparing the work area
- Removing the existing door system
- Evaluating and preparing the opening
- Positioning the new frame and door
- Completing applicable anchoring
- Completing perimeter details
- Installing or adjusting hardware
- Testing operation
- Completing finishing work
- Cleaning the work area
- Completing applicable inspections
The exact process depends on the door and property.
How Long Does Impact Door Installation Take?
Installation time varies based on the opening and project.
A single entry door and a large multi-panel sliding glass door should not be expected to require identical installation schedules.
Factors can include:
- Opening size
- Door configuration
- Existing conditions
- Accessibility
- Structural modifications
- Finishing work
- Inspection requirements
Your contractor can provide a more useful schedule after evaluating the project.
Should You Replace Impact Windows and Doors at the Same Time?
Some homeowners choose to replace all exterior windows and doors during one project.
This can make it easier to evaluate whole-home opening protection together.
Others replace products in phases based on priority and budget.
If you are completing a partial project, identify which openings will be impact-resistant afterward and how the remaining openings will be protected.
How to Compare Impact Door Quotes
Do not compare quotes based only on the total price.
Determine whether each proposal identifies:
- Manufacturer
- Exact product or series
- Door configuration
- Opening dimensions
- Frame material
- Glass package
- Hardware
- Applicable product approval
- Permit responsibilities
- Installation scope
- Removal and disposal
- Finishing work
- Manufacturer warranty
- Workmanship coverage
- Post-installation service
Two proposals for an "impact door" can contain very different products and scopes of work.
