Why Your Sliding Glass Door Is the Priority
Your sliding glass door is almost certainly the largest glass opening in your home. A standard two-panel SGD is 8 feet wide. A three-panel system is 12 feet. Some Florida homes have multi-panel configurations spanning 16-20+ feet.
When that opening fails during a hurricane, the consequences are proportional to its size. Wind-borne debris penetrates the glass, wind rushes in through an 8-16 foot opening, and the resulting internal pressurization (30-60 PSF) combines with external roof suction (40-80 PSF) to produce 70-140 PSF of uplift that can tear the roof off from the inside.
Your sliding glass door is also the opening most likely to be unprotected. Many homeowners install impact windows on their standard windows and an impact entry door on the front but leave the sliding glass door unprotected because the cost of an impact SGD replacement ($3,500-$9,000+) is daunting.
This is a problem because the insurance opening-protection credit (30-45% of your wind premium) requires all openings to be protected. One unprotected sliding glass door voids the full discount.
Hurricane shutters solve this problem at a fraction of the impact door cost. Here's every option.
Shutter Options for Sliding Glass Doors
Accordion Shutters: The Most Popular Choice for SGDs
Accordion shutters mount permanently on tracks above and beside the sliding glass door opening. To deploy, pull both halves closed from each side and lock in the center.
Cost: $600-$1,500 per SGD opening (8 ft standard). $900-$2,000 for 12 ft openings.
Deployment: 2-5 minutes per door (one person, no tools).
Why they're #1 for SGDs: Accordion shutters are the most cost-effective permanent protection for large openings. The EAS (Eastern Architectural Systems) accordion shutter is the best-selling hurricane accordion shutter on the Florida market, and large SGD openings are its primary application.
Water intrusion benefit: FIU Wall of Wind testing found that accordion shutters installed over sliding glass doors reduced water intrusion volume by 77-87%. This is a significant secondary benefit: even when the SGD's structural function (keeping debris out) is handled by the glass, the shutter provides a rain shield that dramatically reduces the water that reaches the door's track system. Given that SGDs are the most vulnerable window type for water intrusion, this added protection is meaningful.
Limitations: When retracted, the folded panels stack on both sides of the opening. On an 8 ft SGD, each stack is approximately 8-12 inches. On a 12+ ft opening, the stacks are larger. The tracks along the top and bottom are permanently visible.
Roll-Down Shutters: Fastest Deployment
Roll-down shutters mount in a housing above the door opening and roll down to cover the SGD. Manual crank or motorized.
Cost: $1,200-$3,000 per SGD opening (8 ft). $1,800-$4,000 for 12 ft.
Deployment: Under 5 minutes (motorized) or 5-10 minutes (manual crank).
Why they work for SGDs: Roll-down shutters are nearly invisible when retracted (hidden in the housing above the opening). For homeowners in HOA communities where visible accordion stacks are an aesthetic concern, roll-downs provide the same protection with a cleaner appearance.
Motorized roll-downs are especially valuable for SGDs because the door openings are wide and heavy manual crank operation can be tiring for 12+ ft spans.
Limitations: 2-3x the cost of accordion for the same opening. Motorized models require electrical wiring and a manual override for power outages. Motor replacement at 10-15 years adds ongoing cost.
Storm Panels: The Budget Option
Aluminum, steel, or clear polycarbonate flat panels that bolt into pre-installed tracks above and beside the SGD opening.
Cost: $300-$800 per SGD opening (8 ft). $500-$1,200 for 12 ft.
Deployment: 30-60 minutes per door with 2 people.
Why they're cheapest: Storm panels require the least material and hardware per square foot. For a homeowner who needs code-compliant protection on a large SGD opening at the absolute lowest cost, panels are the answer.
Polycarbonate (clear) panels allow some light through while deployed, which is a meaningful advantage for SGDs. A home with opaque metal panels over every window and door is dark inside during a storm. Clear panels over the main SGD let natural light in.
Limitations: Heavy (especially steel), require two people, require significant storage space in the garage between storms, and take 30-60 minutes per large opening. Upper-track installation on tall SGD openings (some are 8 ft tall) may require a step stool. Panels must be installed for every storm and removed after, a labor-intensive process for the largest openings.
Hurricane Screens: Lightest Option
Hurricane fabric or mesh screens that deploy over the SGD opening.
Cost: $400-$900 per SGD opening (8 ft).
Deployment: 15-30 minutes per door (one person).
Why they work for SGDs: Screens are dramatically lighter than metal panels (2-5 lbs vs. 30-50+ lbs for a full-width SGD storm panel). One person can handle the deployment. Storage is compact (rolls or folds into a fraction of the space metal panels require).
Limitations: 5-10 year lifespan (UV degradation). Not all products carry Florida Product Approval; verify before purchasing. Limited HVHZ options.

When to Choose Shutters vs. Impact SGD Replacement
Choose Shutters When:
- Budget is the primary constraint. Accordion shutters at $600-$1,500 vs. impact SGD at $3,500-$9,000+. The difference is 3-5x.
- Your existing SGD is in good condition. If the door operates smoothly, the frame is solid, and the glass is adequate for non-hurricane conditions, adding a shutter extends its useful life while providing code-compliant protection.
- You're protecting a secondary opening. A lanai SGD or guest bedroom patio door that doesn't need the daily benefits of impact glass.
- You're doing a hybrid project. Impact windows on primary living spaces, shutters on large doors. This is one of the most common and cost-effective approaches in Florida.
Choose Impact SGD Replacement When:
- Your existing SGD is failing. If it's hard to open, the frame is corroded, the glass is hazy, or the weatherstripping is gone, you're replacing the door anyway. Impact replacement solves two problems at once.
- You value daily benefits. Energy savings (20-40% cooling reduction), noise reduction (STC 32-40), UV blocking (99%), and security apply 365 days a year.
- You're not home during storms. Impact SGDs require no deployment. Shutters do.
- Maximum insurance credit matters. Both shutters and impact doors qualify for the opening-protection credit, but impact doors contribute to better overall air infiltration scores on the wind mitigation form.
- You want to maximize property value. Impact SGDs add to your home's resale value. Shutters don't.

Installation Considerations for SGD Shutters
Track Mounting
Shutter tracks must be anchored into the structural framing around the SGD opening, not into stucco, drywall, or decorative trim. In CBS (concrete block) construction (standard in South Florida), this means masonry anchors into the block above and beside the opening. In wood-frame construction, lag bolts into studs and headers.
The track must span the full width of the SGD opening plus additional coverage on each side (typically 2-4 inches) to ensure the shutter overlaps the opening completely when deployed.
Clearance for Accordion and Roll-Down
Accordion shutters require mounting space on both sides of the opening for the retracted panel stacks. If your SGD is flanked by walls, columns, or other windows with minimal gaps, the accordion may not fit without modifications.
Roll-down shutters require clearance above the opening for the housing (8-12 inches of vertical space). If your SGD extends to the soffit or roofline, the housing may need to be mounted on the fascia or integrated into the soffit during installation.
Lanai and Screen Enclosure Considerations
Many Florida homes have SGDs that open to screened lanais. Shutters can be mounted:
- On the exterior wall (outside the screen enclosure): the shutter protects the SGD directly, but the lanai screen remains unprotected
- At the lanai opening (on the screen enclosure frame): protects both the SGD and the lanai, but requires the screen enclosure frame to support the shutter weight and wind loads, which most standard screen enclosures cannot do
For lanai-enclosed SGDs, the standard approach is to mount shutters on the exterior wall (protecting the SGD directly) and accept that the screen enclosure may sustain damage. Screen enclosures are replaceable; your building envelope is not.
Permits
Permanently mounted shutters (accordion, roll-down) require a building permit in most Florida jurisdictions. Storm panels typically do not require a permit but must be installed on code-compliant tracks. Hurricane screens vary by product and jurisdiction; check your local requirements.
