PGT, CGI, ES Windows, CWS and more — an honest guide to the impact window brands Florida homeowners compare most, and how to pick between them.
Ask three Florida contractors which impact window brand is best and you'll get three different answers — usually the brand each one happens to sell. The truth is more useful: several manufacturers make excellent hurricane windows, and the right pick depends on your budget, your openings, and your design goals. This guide covers the brands Florida homeowners compare most, presented as well-regarded options rather than a definitive ranking, plus the one factor that matters as much as any logo on the frame.
Key Takeaways
Before any brand names, here's what actually separates impact window products:
| Brand | Base | Frame Materials | Relative Price* |
|---|---|---|---|
| PGT | Venice, FL | Vinyl & aluminum | $$ — Florida's volume leader |
| CGI | South Florida | Heavy-duty aluminum | $$$ — premium end of the market |
| ES Windows | Colombia / South Florida | Large-format aluminum | Varies — high-rise & large-opening pedigree |
| CWS | Ocala, FL | Vinyl & aluminum | $–$$ — value-strong regional option |
| Simonton | National | Vinyl | $ — competes on value in vinyl |
| MI Windows / Lawson | National / Florida | Varies by line | Varies — frequent in contractor quotes |
| Eco-Guard™ (the line we install) | Installed from Orlando, FL | Windows & doors, E50–E950 series | Series-matched to each opening and budget |
*Relative tiers as positioned in the profiles below — actual pricing depends on series, glass package and openings. No brand ranking implied.
PGT, headquartered in Venice, Florida, is the largest impact window manufacturer in the state and arguably the most recognized name in the category. Its WinGuard line has been a Florida staple for decades, available in both vinyl and aluminum, with a deep catalog of sizes, shapes, and glass options. Because PGT is so widely installed, most Florida contractors know its products well and replacement parts are easy to source.
CGI, based in South Florida, sits at the premium end of the market. Its Sentinel aluminum series and Estate collection are known for heavy-duty construction and clean architectural lines, and CGI products are a frequent choice in high-end coastal homes built to Miami-Dade standards. Homeowners who prioritize build heft and refined aesthetics often shortlist CGI, typically at a higher price point than volume brands.
ES Windows (Energía Solar) is a Colombian manufacturer with a major presence in South Florida, particularly strong in high-rise condo and commercial projects. Its large-format glass and curtain-wall pedigree translate into impact products suited to big openings and modern designs. For single-family homes it's less common in Central Florida than PGT or CGI, but it's a serious player worth knowing.
Custom Window Systems, manufactured in Ocala, is a Central Florida manufacturer offering vinyl and aluminum impact lines. Its location means practical advantages for Orlando-area projects: shorter shipping distances, familiarity among local installers, and products engineered specifically for Florida code. CWS is often quoted as a value-strong alternative to bigger national names.
Simonton is a large national vinyl window manufacturer whose StormBreaker Plus line covers coastal and impact applications. As a volume producer, Simonton tends to compete on value in the vinyl segment, and its national footprint means broad availability. For Florida homeowners comparing vinyl impact options on a budget, it frequently appears alongside regional brands.
MI Windows and Doors, one of the largest window manufacturers in the U.S., produces impact-rated products for the Florida market, including lines built in the state. Lawson Industries, a long-running Florida manufacturer, serves the impact segment as well. Both show up regularly in contractor quotes across Central and South Florida.
Full transparency: Eco-Guard™ is the house line we install at American Impact Windows & Doors Orlando, so read this profile knowing that. See our Eco Window Systems installation page for the full Orlando line. Eco-Guard™'s laminated impact glass series — E50 through E950 — covers both windows and doors, from single-hung and horizontal-roller windows to sliding glass doors and entry doors, all carrying the Florida product approvals required for permitted installation. We chose it for our projects because the series range lets us match the right frame and glass package to each opening and budget on one supply chain, which keeps lead times predictable. Judge it the same way you'd judge any brand on this page: ask for the approval numbers, the glass specs, and the warranty in writing. You can see the products we install on our impact windows page.
Here's the part most brand guides skip. A top-tier window installed poorly will leak, fail inspection, or worse — fail in a storm. The Florida Product Approval that makes a window "impact rated" assumes it's anchored exactly per the manufacturer's installation instructions: correct fastener type and spacing, proper bucking, approved sealants, the right wind-load calculation for your specific wall and elevation. Miss any of that and the certification on the sticker no longer describes the window in your wall.
That's why the questions in our guide to the best impact window installers in Orlando — license, permits, inspection, crew — matter as much as any brand comparison. A licensed contractor pulling a real permit means a city or county inspector independently verifies the installation. That inspection is your protection, whatever brand you pick.
When quotes arrive with different brands on them, normalize before you compare:
Florida has no shortage of excellent impact window brands — PGT, CGI, ES Windows, CWS, Simonton, MI, and our own Eco-Guard™ line all produce windows that protect homes through real hurricanes when installed correctly. Pick the glass package and frame that fit your home, verify the approvals, and then put your energy into choosing the installer, because that's where projects succeed or fail. If you'd like to see what the Eco-Guard™ line would cost for your home, we'll measure and quote it free.
Honestly, there's no single best brand — several manufacturers, including PGT, CGI, ES Windows, and CWS, make excellent impact windows. The right choice depends on your budget, the size and shape of your openings, and your design preferences. Verify the Florida Product Approval on the exact series quoted, and weigh the installer's quality as heavily as the brand.
Neither is objectively better — they target different buyers. PGT is Florida's volume leader with a broad catalog and wide availability; CGI positions at the premium end with heavier construction and architectural styling, usually at a higher price. Compare the specific series and glass packages in your quotes rather than the brand names alone.
A Notice of Acceptance is Miami-Dade County's product certification for the High-Velocity Hurricane Zone — the strictest wind-borne-debris standard in the country. A window with a current NOA has passed large-missile impact and pressure-cycling tests. Outside South Florida a state Product Approval is what your permit requires, but an NOA is a strong quality signal anywhere.
No. Warranty terms vary widely — frame, glass, seal failure, screens, and hardware often carry different coverage periods, and transferability to a new homeowner differs by manufacturer. Always get the actual warranty document for the specific series you're buying, plus the installer's separate workmanship warranty in writing.
At minimum, just as much. An impact window only performs to its rating when it's anchored per the manufacturer's instructions and passes a permitted inspection. A mid-range window installed correctly will outperform a premium window installed badly. Choose a licensed contractor who pulls the permit, and the brand decision gets much lower-stakes.
