Impact sliding glass doors replace your existing slider with hurricane-rated, laminated-glass units that pass the same TAS 201/202/203 HVHZ tests as impact windows — but they're typically the largest single opening in your building envelope. SafeGuard installs 2-, 3-, 4-panel and pocket configurations from PGT, CGI, ES Windows, and CWS under FL DBPR CGC1532033. Miami-Dade NOA, full permit pathway, in-house crews — never subcontracted.
Reviews
Largest opening · highest insurance leverage
The slider is typically the largest single opening in your building envelope. Upgrading to impact-rated maxes out the wind-mitigation discount opportunity — typically the single largest contributor to your insurance premium reduction.
We file under FL DBPR CGC1532033 and stay the responsible party from sealed plans through final inspection. No owner-builder permits, no subcontracted permit-puller workarounds.
PGT, CGI, ES Windows Multimax, CWS, Eco — we install all five. The right product depends on configuration size, architectural spec, and lead-time constraint. We don't have a single-line catalog.

TL;DR
Impact sliding glass doors replace your existing slider with hurricane-rated, laminated-glass panels that pass the TAS 201/202/203 HVHZ test protocols and carry Miami-Dade Notice of Acceptance. They're typically the largest single opening in a South Florida home's building envelope — and the most consequential door to upgrade for the wind-mitigation insurance discount.
Sliding glass doors are the highest-leverage opening in most South Florida homes. They're typically the largest single opening in the building envelope (a 4-panel slider can be 16-24 feet wide and 8-10 feet tall), they carry the highest daily wear of any door in the home (open-and-close cycling, salt-air exposure, UV degradation on the seals), and they're the opening most likely to fail in a hurricane because the dead-load + cycling stress on standard slider hardware is more than typical hinged doors see.
Impact sliders solve all three problems with one upgrade. The laminated-glass panels (two glass layers bonded around a polymer interlayer) hold together on impact rather than shattering — keeping wind-driven water and projectiles out of the building envelope. The reinforced aluminum frame + multi-point locking + heavy-duty roller hardware handles cycling stress for decades. And the Miami-Dade NOA on the assembly is what unlocks the wind-mitigation insurance discount — typically 15-35% off the wind portion of your premium for the slider's full lifespan.
SafeGuard installs 2-, 3-, 4-, and 6-panel sliding glass door configurations + pocket configurations (panels disappear into the wall) + corner-meet configurations (two sliders meet at a corner with no center post) from PGT, CGI, ES Windows Multimax, CWS, and Eco. Every install goes through the full HVHZ permit pathway under FL DBPR CGC1532033 — sealed engineered plans, NOA verification per opening, Notice of Commencement filing, and both rough + final inspections.
Answer
2-panel (one fixed, one operating), 3-panel (one or two operating), 4-panel (two operating + two fixed, or four operating on premium), pocket (panels disappear into the wall), corner-meet (two sliders meet at a 90° corner with no post), and oversized configurations (Multimax up to 12'+ tall).
2-panel is the standard residential configuration — one fixed panel + one operating panel, typically 6-12 feet wide. Smallest opening in the SGD category. Best fit for bedrooms opening to lanais, secondary patios, and any opening where a wider slider isn't needed.
3-panel is the most-installed configuration in the SafeGuard portfolio for whole-home replacements — one operating panel + two fixed (XOO or OXO), typically 12-18 feet wide. Standard living-room-to-lanai opening on most South Florida single-family homes built since 2000.
4-panel offers more glass area + multiple operating options — typically 16-24 feet wide. Premium configurations (OXXO with two operating + two fixed, or XXXX with all four operating) give the home a wall-of-glass aesthetic. Required wind-load engineering at the 4-panel size.
6-panel is the wall-of-glass premium configuration — typically 24-32 feet wide. Available in OXXXXO (two operating + four fixed) or full-operating (all six panels). Requires premium aluminum framing (CGI Sentinel, ES Windows Multimax) and engineering review.
Pocket configurations disappear the panels into the wall when fully open — the visible doorway has zero panel obstruction. Premium custom configuration; requires the wall to accommodate the pocket cavity (typically 6-10" deep). Architect-spec category.
Corner-meet configurations have two sliders meeting at a 90° corner with no center post — the corner of the room becomes a complete glass opening when both sliders are open. Architectural specialty; available on ES Windows Multimax and CGI Sentinel. Premium pricing.

Impact sliding glass door installation in South Florida runs $4,000-$15,000 per opening installed depending on size (2-panel cheapest, 6-panel premium), brand, glass tier, and any HOA color rules. A standard 12-foot 3-panel slider on a single-family home typically runs $5,500-$8,500; a 24-foot 4-panel runs $9,000-$15,000; oversized Multimax or CGI Sentinel architectural configurations run $15,000-$30,000+. Pricing always includes the door + permit + sealed plans + NOA verification + both rough and final inspections.
Yes for South Florida — they're the highest-leverage opening in your building envelope. The slider is typically the largest single opening, carries the highest daily wear, and is the most likely to fail in a hurricane. Upgrading to impact-rated does three things at once: protects the structure during a storm, qualifies for the wind-mitigation insurance discount (15-35% off the wind portion of your premium), and adds resale value (listed as a feature on every MLS).
Permit review runs 21-50 business days depending on jurisdiction. Once permitted, the actual installation on a 3- or 4-panel slider takes a full day; on a 2-panel takes a half day; on 6-panel or pocket configurations runs 1-2 days. Multi-day inspections aren't typical for sliders (single inspection at completion). The end-to-end timeline from contract signing to permit-closed is typically 6-10 weeks.
Standard configurations top out around 24 feet wide × 10 feet tall (4-panel). Premium architectural configurations from CGI Sentinel and ES Windows Multimax push to 32 feet wide × 12+ feet tall — these require engineering-custom NOA review (8-12 week lead time vs 4-8 for stock sizes). Pocket configurations and corner-meet configurations are available on most premium products. We run the wind-load calc per opening and confirm the configuration is achievable before quoting.
Yes — pocket configurations and corner-meet configurations both achieve the 'no visible center post' aesthetic. Pocket: panels disappear into the wall cavity when fully open (~6-10" wall depth required). Corner-meet: two sliders meet at a 90° corner with no center post (corner becomes an open glass walkway when both sliders are fully open). Both are architectural-specialty configurations available on premium product lines (CGI Sentinel, ES Windows Multimax). Premium pricing.
30+ years on premium aluminum-frame products with proper installation and routine maintenance (track cleaning, roller lubrication every 5-7 years). The laminated-glass seal is the typical service item — manufacturer warranties cover seal failure for 10-25 years on most products and lifetime on PGT WinGuard. Roller hardware is the second service item — typically replaced once during the door's lifespan. We service warranty calls in-house.
PGT WinGuard (most-installed in the SafeGuard portfolio — lifetime warranty, in-state lead times), CGI Sentinel + Sparta (slim aluminum sightlines for whole-home), ES Windows Multimax (oversized + architectural specialty — 12'+ tall, corner-meet, pocket), Custom Window Systems 540 Aluminum (Pella-backed value-tier), and Eco Window Systems (independent, Medley FL plant). All five carry Miami-Dade NOA across their slider configurations.
