What is the best hurricane impact window brand for Florida?

No single brand is best for every homeowner. PGT WinGuard offers the broadest NOA portfolio and the deepest contractor network in South Florida. CGI is excellent for narrower aluminum sight-lines and commercial work. ECO Window Systems offers strong value on standard configurations. ESW dominates large multi-panel sliding glass doors. CWS (Custom Window Systems) is a Florida-manufactured option with both aluminum and vinyl impact lines and a strong NOA catalog for residential remodels. The right choice depends on opening configuration, budget, and finish requirements.

Is PGT better than CGI?

PGT and CGI are both top-tier Miami-Dade NOA approved manufacturers and either is a defensible choice. PGT has a broader product catalog, larger contractor network, and stronger residential brand recognition. CGI manufactures locally in Miami, offers narrower sight-lines on its commercial-grade aluminum lines, and is often preferred for modern architectural builds. For a standard South Florida residential install, the choice usually comes down to which brand the contractor specializes in and which configurations price best for the project.

Are vinyl impact windows as good as aluminum?

Vinyl impact windows are equally code-compliant when NOA approved, more thermally efficient (lower U-factor), and typically 10–18% cheaper than aluminum. The trade-offs: thicker sight-lines, fewer color and finish options, and a narrower selection of NOA-approved configurations — particularly for large openings and sliding glass doors. Florida-based CWS is one of the more common NOA-approved vinyl options for HVHZ residential work; for standard single hung and horizontal roller openings, vinyl is a solid value choice.

What is the warranty on PGT WinGuard windows?

PGT WinGuard impact windows carry a 10-year limited warranty on glass breakage from impact, plus a 20-year limited warranty on the frame and seal. Installation labor is warranted separately by the installing contractor, typically for 1 to 2 years. Warranty is transferable to subsequent homeowners — a meaningful resale value factor.

The Best Hurricane Impact Window Brands for Florida (2026)

The South Florida impact window market is dominated by five manufacturers EZPZ Windows works with day-to-day: PGT, CGI, ECO Window Systems, ESW, and CWS (Custom Window Systems). Each has a clear sweet spot. The right brand for your project depends on opening configuration, budget tier, finish requirements, and whether your contractor is certified to install that brand at scale.

TL;DR

Best overall: PGT WinGuard (broadest NOA library, deepest contractor network). Best value on aluminum: ECO Window Systems. Best Florida-made flexible option (aluminum + vinyl): CWS. Best for big sliding glass doors: ESW. Best for narrow modern sight-lines: CGI Sentinel/Estate.

Quick comparison

Brand	Frame	Price tier	Best for
PGT WinGuard	Aluminum or Vinyl	$$ – $$$	Broadest config range, residential default
CGI Sentinel / Estate	Aluminum	$$$	Narrow sight-lines, modern architecture
ECO Window Systems	Aluminum	$$	Standard configs, value pricing
ESW (ES Windows)	Aluminum	$$$	Large multi-panel sliding glass doors
CWS (Custom Window Systems)	Aluminum or Vinyl	$$	Florida-manufactured value option, mid-tier residential

Deep dives

1. PGT Innovations — WinGuard

Aluminum or Vinyl Manufactured: Venice, FL & North Carolina $$ – $$$ price tier

Why it wins: PGT is the largest US impact window manufacturer and the default brand for most South Florida residential remodels. Its NOA portfolio covers more sizes, configurations, and design pressures than any other manufacturer. The WinGuard line offers both aluminum and vinyl frames, so a single brand can supply an entire home regardless of budget tier.

Best for: Whole-home residential replacements where the homeowner wants brand consistency and a wide range of standard sizes that price competitively.

Trade-offs: PGT residential lines have slightly thicker sight-lines than CGI commercial aluminum. Lead times during peak season (April–August) can stretch to 8–12 weeks.

Warranty: 10-year limited warranty on glass breakage from impact, 20-year limited warranty on frame and seal. Transferable.

2. CGI Windows & Doors — Sentinel & Estate

Aluminum Manufactured: Miami, FL $$$ price tier

Why it wins: CGI is Miami-based and supplies a meaningful portion of the high-end South Florida commercial and architectural residential market. Its aluminum frames have noticeably narrower sight-lines than PGT WinGuard aluminum, which matters for modern architecture and for openings where the homeowner wants maximum glass area. CGI's design pressure ratings on large fixed lites are best-in-class.

Best for: Modern architectural builds, large picture windows, expansive view-driven layouts, commercial multi-family.

Trade-offs: No vinyl option, so the entry-level price floor is higher than PGT. Narrower nationwide brand recognition (mostly known to Florida contractors and architects).

Warranty: 10-year limited on glass and frame.

3. ECO Window Systems

Aluminum Manufactured: Hialeah, FL $$ price tier

Why it wins: ECO is one of the largest Florida-based extruded-aluminum impact window manufacturers and is often the lowest-cost NOA-approved aluminum option that still has a strong contractor network and adequate spare-parts logistics. Standard single hung and horizontal roller configurations price very competitively.

Best for: Standard residential replacements where the homeowner wants NOA-approved aluminum at the most competitive price point.

Trade-offs: Smaller catalog than PGT — custom sizes, geometric shapes, and large sliding glass doors may have limited NOA configurations or require longer lead times. Brand recognition lower than PGT and CGI.

Warranty: 10-year limited on glass and frame.

4. ESW (ES Windows)

Aluminum Manufactured: Colombia $$$ price tier

Why it wins: ESW dominates the large multi-panel sliding glass door market in South Florida. Its 3-panel (XOX) and 4-panel (XOOX) sliders have NOA approvals at sizes and design pressures that few other manufacturers match, with thin commercial-grade frames that look modern and let in maximum light.

Best for: Waterfront and view-driven homes with big sliders to the patio, pool, or balcony.

Trade-offs: Lead times are longer than US-manufactured options (imports from Colombia); custom sizing requires careful coordination. Warranty service logistics are slightly more involved.

Warranty: 10-year limited on glass and frame; warranty service routed through the US distributor.

5. CWS — Custom Window Systems

Aluminum or Vinyl Manufactured: Ocala, FL $$ price tier

Why it wins: CWS is a Florida-based, family-owned manufacturer with a strong Miami-Dade NOA catalog covering both aluminum and vinyl impact windows and doors. Because both frame materials come from the same supplier, a single CWS order can cover a whole home — aluminum on the openings that need the narrowest sight-lines and vinyl on the openings where thermal efficiency matters most — without juggling two separate manufacturers, lead times, or warranty processes.

Best for: Florida residential remodels where the homeowner wants competitive pricing, a single-source supplier across both frame materials, and the logistical advantage of an in-state manufacturer (shorter lead times than imports, simpler warranty service).

Trade-offs: Smaller national brand profile than PGT — less recognition outside Florida. Catalog is more focused on standard residential configurations; very large or highly custom architectural openings may still route to PGT, CGI, or ESW.

Warranty: Limited lifetime on residential frames and seal, 10-year limited on glass.

How to choose

Match the brand to the opening

Almost no full-home install uses a single brand for every opening. Common patterns:

Standard openings (single hung, horizontal roller, picture): PGT WinGuard, ECO, or CWS
Large sliding glass doors: ESW or PGT EnergyVue Sliding
Architectural fixed glass: CGI Sentinel/Estate
Geometric (circle, half moon, eyebrow): PGT custom
Budget-conscious whole-home replacements: ECO (aluminum) or CWS (vinyl)

Verify NOA numbers before signing

Every brand listed here has a current Miami-Dade NOA portfolio. But specific configurations (size, glass thickness, design pressure) may or may not be NOA-approved. Always ask your contractor for the specific NOA number for each product on your quote and verify them on the Miami-Dade Product Control online directory. See our Miami-Dade NOA guide for the verification process.

Check contractor certification

Most manufacturers require the installing contractor to be certified to install their products under the NOA. PGT, CGI, and CWS all maintain certified-installer lists. Confirm your contractor is on the manufacturer's certified list before signing — DIY or uncertified installations can void the warranty and the wind-mitigation insurance discount.

Don't over-index on brand

For most South Florida residential remodels, any of the five brands (PGT, CGI, ECO, ESW, CWS) delivers code-compliant, hurricane-rated protection that performs equivalently in real storms. The differences that actually matter day-to-day are: sight-line aesthetics, contractor familiarity with the install procedure, and warranty service logistics — not raw impact resistance.

Frequently asked questions

What is the best hurricane impact window brand?: No single brand wins for every project. PGT WinGuard is the most-installed residential default. CGI wins on narrow sight-lines. ECO wins on standard-config aluminum value. ESW wins on large sliding glass doors. CWS wins as a single-source Florida-made supplier offering both aluminum and vinyl from one catalog.
Is PGT or CGI better?: Both are top-tier NOA-approved manufacturers. PGT offers a broader catalog and deeper contractor network; CGI offers narrower sight-lines and is locally manufactured in Miami. Either is a defensible choice — the right answer usually depends on the specific configurations being quoted.
Are vinyl impact windows as good as aluminum?: Equally code-compliant when NOA approved, more thermally efficient (lower U-factor), and 10–18% cheaper. Trade-offs are thicker sight-lines and a narrower NOA catalog for large openings. CWS is one of the more common NOA-approved vinyl options EZPZ Windows installs for HVHZ residential work.
What is the warranty on PGT WinGuard windows?: 10-year limited warranty on impact-related glass breakage and 20-year limited warranty on frame and seal. Transferable to subsequent homeowners.
Are imported impact windows (like ESW) safe?: Yes, as long as they carry a current Miami-Dade NOA. The NOA process is identical regardless of where the manufacturer produces the product — every NOA-approved window has passed the same TAS 201/202/203 tests at an accredited US laboratory.
Can I mix brands in one project?: Yes, and it is very common. Most South Florida installs use one brand for standard openings (e.g., PGT WinGuard for single hung) and a different brand for the largest sliding glass doors (e.g., ESW). The warranty and insurance discount apply per opening based on each product's NOA.
