ES Windows vs. PGT: Which Impact Window Is Better in Florida?
Both ES Windows and PGT make Miami-Dade NOA approved impact windows lawful anyplace in Florida including the High Velocity Hurricane Zone. Neither is more safe than the other. The key variations are price, lead time, standard equipment and where they are made. PGT is costlier and treats Features include low-E glass and quality finishes. ES Windows is cheaper, ships faster and has those features as standard.
We install both brands throughout Miami-Dade, Broward, Palm Beach, Collier and Lee counties, so what follows is what we see on estimates and project sites, not a spec sheet read from a distance.
Is ES Windows better than PGT?
ES Windows is not inherently better than PGT. Both provide hurricane-rated products for the demanding Florida market. The best decision depends on the window series, the glass package, the design pressure, the energy performance, the budget, the warranty and the installation needs. PGT features a broad variety of impact products. ES Windows has superior residential and architectural solutions. Compare authorized product specifications rather than picking by brand name alone.
No one brand wins everything, they win on different projects. ES Windows offers more features per dollar and faster lead times, making it the better alternative for full house replacements with a fixed budget. PGT has the deepest product library in the business, Florida manufacturing, and the highest name awareness at resale. And that matters on complex homes and on properties you intend to sell.
But if your only question is whether one will safeguard your home better than the other, the answer is no. They are both tested to the identical Miami-Dade protocols. Either brand makes a window that is properly allowed, properly installed and does the job.
Who makes ES Windows?
ES Windows is a member of the Tecnoglass group. In 2016, Tecnoglass purchased ESWindows, LLC, further extending its footprint in the U.S. and its vertically integrated manufacturing capabilities. ESWindows designs and manufactures aluminum and glass window and door solutions for the residential and commercial markets. The company has a history of more than 40 years in the market and manufactures goods that are designed to be hurricane-resistant, energy efficient and architecturally performing.
ES Windows is the residential and light commercial division of Tecnoglass Inc. (NYSE: TGLS), a publicly traded manufacturer situated in Barranquilla, Colombia. Tecnoglass is vertically integrated with its own glass production, its own aluminum extrusion, rather than sourcing components from suppliers. That control over the supply chain is how the brand was able to keep producing when the rest of the market couldn’t, and it’s how ES Windows became the highest-volume impact window manufacturer in Florida in the early 2020s.
Honest caveat homeowners ask about: ES Windows are not built in the U.S.A. The glass and the aluminum are from Colombia. That has a practical consequence in 2026, imported finished aluminum windows carry Section 232 duties and Tecnoglass has announced price increases on 2026 orders because of it. The product for a window ordered today is imported and the manufacturer is investing in US production capability.
Who makes PGT?
PGT Windows & Doors is made by PGT Industries, a Florida based window and door manufacturer with headquarters in North Venice, Florida. The company has various product families, including WinGuard, WinGuard Vinyl, EnergyVue, ClassicVue Max, Sparta, Scout, PGT Commercial and Estate by PGT. Its range comprises impact-resistant and non-impact windows and doors for residential and commercial applications.
PGT manufactures in Venice, Florida, and has made windows there since 1980. PGT pioneered the impact window category: when Hurricane Andrew prompted a revision of the Florida Building Code in 1992, PGT debuted WinGuard in 1996 as the first complete line of impact-resistant windows and doors engineered to comply with the new code. That heritage is why PGT has one of the deepest Miami-Dade NOA collections of any manufacturer.
PGT is now owned by MITER Brands, who purchased the company for $3.1 billion and took it private with Koch Equity Development. The Venice manufacturing did not change ownership. For Florida manufacturers, the real-world benefit to homeowners is the after-sale, warranty parts are delivered from within the state instead of through a port.
Do both brands carry Miami-Dade NOA approval?
Yes, both ES Windows and PGT have products with Miami-Dade County Notice of Acceptance, or NOA, approvals. But approval is for certain goods, combinations and assemblies, not necessarily for every product a company makes. Before installing in a High-Velocity Hurricane Zone, verify the exact NOA, product series, size, glass configuration, design pressures and installation requirements for your project.
This is where most brand comparisons go wrong. Florida has two approval systems, and they are not interchangeable. The approvals are not Miami Dade. The statewide system issues Florida Product Approvals, FL#. Miami-Dade and Broward in the High Velocity Hurricane Zone require a Miami-Dade NOA for your permission. Typically, a Florida Product Approval is adequate for Palm Beach, Collier and Lee counties, however local adjustments apply.
More importantly, it is a specific product in a certain size and configuration that is approved, not a brand. Both “ES Windows is NOA approved” and “PGT is NOA approved” are true, and both are nearly useless by themselves. The number that matters is the one for the specific unit that will fit your exact hole at the design pressure dictated by your elevation. We pull that number for each opening before we order it, and it goes on the permit application. Is this the time to inquire again if a salesman informs you that a brand is approved and then cannot produce the permission papers for your window size.
ES Windows vs. PGT at a Glance
ES Windows aluminum lines are rated to design pressures up to +100 / −140 psf. PGT WinGuard Aluminum is rated up to +90 / −130 psf. PGT WinGuard Vinyl is rated at +65 / −70 psf, the greatest design pressure for a vinyl impact window, and has a Miami-Dade NOA, something very few vinyl products can claim. PGT warrants the frame for a limited lifetime and the insulated glass unit for 10 years. PGT will usually offer about 20% over ES Windows for like specs.
What product lines does each brand offer?
ES Windows offers household lines including Prestige, Legacy, Elite, Multimax, Elite uPVC, Series 76, Series 88 and entry doors. They also offer architectural and commercial goods. PGT offers WinGuard, WinGuard Vinyl, EnergyVue, ClassicVue Max, Sparta, Scout, PGT Commercial and Estate by PGT. Both manufacturers provide a variety of window and door layouts and impact-resistant alternatives for Florida applications.
ES Windows: Multimax, Elite y Prestige
ES Windows comes in three tiers and the names are on your quote so it is worth knowing which one you are being sold to. Multimax is the performance level, aluminum single hanging, fixed and horizontal slider units on a 2-3/8 inch frame, rated for both big missile and small missile impact, with design pressures up to +100 / −140 psf on various configurations. It is equipped for multi-family and production work and comes standard with coastal appropriate coatings and corrosion resistant hardware. Elite is the middle-of-the-line aluminum and the one most South Florida homes get. It features the whole residential range including casement, single hung, fixed picture, sliding window, French door and sliding glass door, all in one certified system. The practical advantage of that breadth is you can get a full house on one approval, not four. Architectural level: Prestige – Thermal barrier aluminum, Pivot and folding door systems. This is where you get floor to ceiling glass and huge openings — and it is priced accordingly.
PGT: WinGuard Aluminum & WinGuard Vinyl
WinGuard has been PGT’s impact platform since 1996. It is available in two frame materials. WinGuard Aluminum is the coastal spec—higher design pressures, thinner sightlines, more glass in the same rough hole. It transitions from single hung to sliding glass doors on a single HVHZ-certified frame structure. The energy-efficiency specification is WinGuard Vinyl. Vinyl provides superior insulation than aluminum, and never rots. PGT’s vinyl is one of the only vinyl impact products with a Miami-Dade NOA. The trade off is the +65 / −70 psf design pressure ceiling, which rules it out on wide openings and high exposure elevations. PGT also manufactures WinGuard with its own Diamond Glass, a lower impact laminate, and SecureConnect strengthened frame connectors.
How much more does PGT cost than ES Windows?
There is no specific percentage that shows how much more PGT costs than ES Windows. Prices depend on the product line, window size, glass package, frame material, hardware, design requirements, quantity, difficulty of installation and the price of the dealer. A premium PGT system may be more expensive than an entry-level ES system, and identical configurations may also range in price. Always compare on an equal basis of specs and installation scope.
PGT will usually estimate roughly 20% more than ES Windows for similar specs, however that headline number is deceiving unless you understand what is included.
ES Windows is available with Low-E coating, premium Kynar-type paint finishes and stainless steel hardware for its base pricing. PGT prices them as an upgrade. So a PGT quotation that seems similar to an ES Windows quote is generally a stripped PGT quote clear glass, standard finish, standard hardware – and the gap opens right back up when you specify it to match. Compare glass packaging, finish, hardware and design pressure line by line prior to comparing totals between two quotations.
Which brand delivers faster?
Neither brand is a guaranty for speedier delivery on all projects. Lead times are dependent upon the product series chosen, custom size, glass configuration, color, quantity, production capacity, shipping, dealer inventories and installation scheduling. ES Windows and PGT both have several product lines with various production needs. The best way to approach a renovation project is to get a current written lead-time estimate.
ES Windows has been executing shorter lead times than PGT for years now and it is the single main reason the brand gained market share during the supply-chain years. Usually it’s the decisive factor if you’re trying to finish before hurricane season opens on June 1.
PGT has the advantage on the opposite end. The windows are made in Venice, thus guarantee parts and replacement units come from within Florida, not through an import cycle, which means a broken sash or a failed seal is fixed in days.
Monthly lead times and whatever you write down on paper go old. Ask us what both brands are quoting the week you are deciding and we will tell you what our last 4 orders actually took.
Which brand is better for a coastal home?
If the product chosen is appropriately certified and defined for the conditions at the property, both ES Windows and PGT might be great solutions for coastal residences. Look beyond the name and consider impact rating, design pressure, corrosion resistant hardware, glass layout, frame material, energy performance and appropriate approvals . ES Windows and PGT both offer products built for the harsh coastal and hurricane environment.
For residences on or near open water, either type of aluminum is the perfect answer, and the exact design pressure is more important than the badge. Salt air, wind-driven rain and higher negative pressures on exposed altitudes all favor aluminum frames and disadvantages the vinyl DP ceiling. Both brands employ marine-grade or coastal treated aluminum and corrosion resistant hardware.
Vinyl gets its stripes onshore. PGT WinGuard Vinyl is the right choice if your home is a few miles away from the water, your openings are normal sizes, and your main concern is the cooling bill, reduced U-factor, lower price, full Miami-Dade certification.
The anchoring is the one item that does not change by brand. A correctly certified window, put into the wrong substrate, with the improper fasteners, will fail at the wall, not the glass. That’s not a manufacturing question, that’s a contractor question.
Frame material is a separate decision from brand, and in South Florida it usually comes down to the design pressure your openings require. [Read our full comparison of vinyl vs. aluminum impact window frames →]
What does each warranty actually cover?
The extent of warranty coverage is contingent upon the product and warranty document. ES Windows asserts that its warranties may encompass replacement parts and components; however, installation or onsite replacement may not be included. PGT asserts that its products are supported by limited warranty coverage and offers distinct warranties for its product families. It is imperative to review the precise warranty for the series you have chosen, which includes the glass, frame, hardware, finish, labor, and exclusions.
PGT offers a 10-year limited warranty on the insulating glass unit and a limited lifetime warranty on the frame, which is available in aluminum or vinyl. ES Windows provides a multi-year finish warranty to protect its premium paint finishes from chalking and color loss.
Consult the warranty PDF rather than the brochure. Lifetime is specified in the brochures of all manufacturers, and the document contains a list of exclusions, a prorated schedule, and maintenance conditions. The exclusion that householders encounter most frequently is installation: a warranty claim for a window that was installed without a final inspection and a closed permit is a challenging claim. We pull the permit, schedule the inspection, and provide you with the closed documentation, which is the foundation of a claim that endures for years.
Which one we install, and when?
Instead of employing a one-size-fits-all approach, we suggest the window brand and product series that are most suitable for the needs of your home. For projects in South Florida, we assess the opening size, design pressure, impact requirements, architectural style, energy objectives, coastal exposure, budget, and any relevant approvals. If ES Windows is the most suitable option, we employ it; however, when PGT is more suitable for the project, we suggest PGT.
We have no reason to direct you, as we stock and install both brands. The following is the actual method of specification:
- Replacement of the entire house with a fixed budget, a desire for a coastal finish and low-E glass, and no additional fees—ES
- Windows Elite.
Large openings, direct coastal exposure, and high negative design pressure—aluminum from either brand, selected based on the approval that accommodates your dimensions. - PGT WinGuard Vinyl is the preferred choice for standard openings in an inland home where the primary concern is the energy bill.
- Architectural project, pivot or folding doors, and oversized glass—ES Windows Prestige.
- A homeowner who desires a Florida-built home with the quickest warranty turnaround—PGT.
- The brand that is offering the lesser lead time that month must meet a strict deadline prior to hurricane season.
Frequently Asked Questions
Is ES Windows better than PGT?
In general, neither option is superior. The cost of ES Windows is lower, it is shipped more quickly, and it comes with Low-E and premium coatings as standard. The PGT is constructed in Florida, has a more extensive catalog, is more expensive, and has a higher level of resale recognition. Both have been approved by the Miami-Dade NOA and comply with the Florida Building Code.
Are ES Windows made in the USA?
No. Tecnoglass manufactures ES Windows in Barranquilla, Colombia, where the company operates its own glass and aluminum production facilities. PGT is produced in Venice, Florida. If you are concerned about indigenous manufacturing, this is a significant distinction between the two.
Do ES Windows have Miami-Dade NOA approval?
Indeed, across the aluminum lines. The vinyl products have a more limited HVHZ coverage. The inquiry should not be whether the brand is approved, but rather whether the specific unit in your opening is authorized, as approval is granted per product, size, and configuration. Before placing an order, we verify that number.
Who owns PGT now?
PGT is currently under the ownership of MITER Brands, which acquired the company in a $3.1 billion transaction that was funded by Koch Equity Development and successfully privatized it. Venice, Florida, continues to be the site of manufacturing.
How much cheaper are ES Windows than PGT?
On matched specifications, ES Windows typically comes in around 20% below PGT. The gap is narrower than it looks on some quotes because ES Windows includes Low-E glass, premium finishes and stainless hardware in the base price while PGT prices them as upgrades.
What is the difference between WinGuard and ES Windows Elite?
WinGuard is PGT’s impact platform, available in aluminum or vinyl. Elite is ES Windows’ mid-tier aluminum line. Both cover the full residential range of window and door types under one certified system. WinGuard Aluminum reaches +90 / −130 psf; ES Windows aluminum reaches +100 / −140 psf on some configurations.
Which is better for a house near the beach?
Aluminum from either brand. Vinyl impact windows top out at +65 / −70 psf, which is often below what an exposed coastal elevation requires, and aluminum handles large openings better. The deciding factor is the design pressure your opening needs, which we calculate before quoting.
Does My Safe Florida Home cover both brands?
Yes. The grant is tied to the improvement, not the manufacturer — any impact window that meets the program’s requirements qualifies. Remember that My Safe Florida Home reimburses the homeowner: you pay us in full, then the state sends your money to you after the paperwork clears.
