When homeowners compare impact windows, three names frequently come up in South Florida: PGT, Mr. Glass and ES Windows. Each manufacturer offers hurricane-resistant windows and doors designed for Florida’s demanding climate and building codes. So, is one manufacturer clearly better than the others?
The short answer is that all three manufacturers produce quality impact-resistant products. The most important differences are usually not basic hurricane protection, but product selection, appearance, customization, warranty terms and price.
Comparable Protection When Properly Selected and Installed
Impact windows are not approved simply because of the name printed on the frame. Each specific product and configuration must be tested and approved for particular sizes, wind pressures, glass types and installation methods.
When comparable PGT, Mr. Glass and ES Windows products carry the appropriate Florida Product Approval or Miami-Dade Notice of Acceptance for a project, all three can provide excellent hurricane protection. A properly selected and installed window from any of these manufacturers can be a dependable choice.
Installation is just as important as the manufacturer. Correct measurements, approved anchors, proper spacing, suitable substrates and installation in accordance with the product approval all affect how the completed opening performs. Even an excellent window can experience problems when it is ordered incorrectly or installed outside its approved requirements.
PGT: The Most Recognized Name
PGT’s principal advantage is name recognition. The company has been prominent in the Florida impact-window market for many years, and many homeowners ask for PGT by name before receiving an estimate.
That recognition can provide additional confidence, particularly for customers who prefer a familiar brand. PGT also offers a broad selection of aluminum and vinyl impact products, including its well-known WinGuard line, together with an established dealer and service network.
However, greater name recognition does not automatically mean that every PGT product is stronger or better than every comparable product from Mr. Glass or ES Windows. In some cases, customers may pay a premium for the PGT name even though another approved product offers comparable protection, appearance and performance.
Mr. Glass: Flexibility and Custom Capabilities
Mr. Glass is a South Florida manufacturer offering residential and commercial impact-window and door systems. The company is particularly competitive for custom configurations, oversized openings, storefronts, commercial doors and projects requiring specialized aluminum systems.
Mr. Glass may provide additional flexibility when a standard product does not fit the design or when a project requires a specific size, finish or configuration. Its local manufacturing presence can also be attractive to South Florida contractors and customers.
Like ES Windows, Mr. Glass does not have the same level of homeowner name recognition as PGT. Nevertheless, the company manufactures approved impact products that can provide comparable protection when the correct system is specified and properly installed.
ES Windows: Contemporary Design and Broad Selection
ES Windows manufactures an extensive range of residential and commercial window and door systems. Its products are often selected for contemporary homes, condominiums, large glass openings and projects where clean sightlines and architectural appearance are important.
ES offers several product levels, allowing homeowners and builders to balance appearance, performance and budget. Depending on the series, ES products can offer premium finishes, coastal hardware, insulated glass and strong energy and sound-control performance.
For many projects, ES Windows provides quality comparable to PGT while offering different styling, configurations or pricing. Although ES is well known among contractors, builders and architects, its name may not be as immediately recognizable to the average homeowner as PGT.
Which Manufacturer Should You Choose?
There is no single manufacturer that is best for every home or every opening. PGT, Mr. Glass and ES Windows all manufacture quality impact-resistant products. The better choice depends on the requirements of the individual project.
Homeowners should compare:
- The exact product series—not only the manufacturer
- Florida Product Approval or Miami-Dade NOA
- Approved maximum size and design pressure
- Laminated or insulated-laminated glass configuration
- Energy ratings, including SHGC and U-factor
- Frame style, sightlines and available finishes
- Hardware and coastal-corrosion protection
- Warranty coverage and exclusions
- Total installed price
- The experience and reputation of the installation contractor
The Bottom Line
PGT, Mr. Glass and ES Windows all produce quality impact windows capable of protecting Florida homes when the products are correctly selected and installed. PGT’s biggest advantage is its stronger name recognition among homeowners. Mr. Glass can be especially valuable for customized residential and commercial applications, while ES Windows often stands out for contemporary design and its broad architectural product selection.
Rather than choosing solely by brand name, homeowners should evaluate the exact window series, product approval, energy performance, warranty, appearance and quality of installation. The best impact window is the approved product that fits the opening, meets the project’s performance requirements and is installed correctly by an experienced contractor.
