The Two Brands Every South Florida Homeowner Compares
If you are shopping for impact windows in South Florida, you will eventually come down to ES Windows and PGT. Here is an honest head-to-head from a contractor who installs both.
Brand Context
ES Windows, manufactured by Tecnoglass, overtook PGT to claim the number one volume position in Florida's impact window market in 2022 — making it the most-installed impact window brand in the state by unit count. Florida-based, designed specifically for coastal environments.
PGT is the largest impact window manufacturer in North America, founded in 1980. Their WinGuard line has been the residential benchmark in South Florida for decades. Rated to withstand winds up to 175 mph — Category 5.
Both carry Miami-Dade NOA approval. Both meet Florida Building Code. The differences are real but not about whether your home will be protected.
Where ES Windows Has the Edge
ES Windows includes Low-E glass and stainless steel hardware as standard on most product lines — features that PGT typically charges extra for. Lead time on ES Windows runs approximately 5 to 6 weeks from order to delivery. For homeowners on a tighter timeline, especially before hurricane season, this matters. ES Windows is generally priced lower than PGT WinGuard for comparable specifications.
Where PGT Has the Edge
PGT offers a broader product selection with more architectural configurations, more size options for larger and custom openings, and stronger brand recognition in the South Florida market — which can matter for resale value. PGT's glass warranty is strong and their dealer support network is extensive. For homeowners who want the widest range of product options or who are doing a high-end architectural project, PGT WinGuard is often the right choice. Lead time runs approximately 10 to 12 weeks.
2026 Note on Pricing
Aluminum tariffs introduced in 2026 have pushed aluminum frame costs up across both brands. ES Windows passed through a price increase earlier this year. The traditional cost gap between the two brands has narrowed slightly, though ES Windows remains generally more cost-effective for comparable specifications.

The Honest Answer
Neither brand is universally better. ES Windows is the right call for homeowners who want premium features included at a lower price point with faster delivery. PGT WinGuard is the right call for homeowners who want the broadest product selection, maximum brand recognition, or specific architectural configurations and are willing to wait longer and pay more.
