ESW Windows Review: Series, Glass & Approvals for South Florida (2026)
ES Windows (ESW) is one of the three most-installed impact window brands in South Florida — yet it gets far less attention than PGT. That gap exists because of marketing budgets, not performance. Here's an honest look at what ESW delivers, where it falls short, and whether it's the right choice for your home. For the full head-to-head, see our Mr Glass vs PGT vs ESW comparison.
ESW delivers comparable HVHZ protection to PGT WinGuard, with a verified factory-direct price for your exact size. It's the best balance of performance, certification, and price for most South Florida homes that aren't directly on the oceanfront. If you're on a budget but won't compromise on NOA-approved, HVHZ-rated products, ESW is the right call.
What Is ESW (ES Windows)?
ESW is ES Windows — the trade name of E.S. WINDOWS, LLC — a manufacturer of impact-resistant windows and doors. Its Elite (E-Line) catalog states more than 40 years as a window and door manufacturer and specifies high-performance Low-E glass options by Tecnoglass. The residential range spans three separate lines: Elite (E-Line), MultiMax and Prestige, each with its own series, size limits and pricing.
ESW is part of Tecnoglass (NASDAQ: TGLS), which manufactures in a vertically integrated complex of more than 5 million square feet in Colombia. ESW's impact lines are designed for HVHZ use — the High Velocity Hurricane Zone covering Broward and Miami-Dade counties — with Florida Product Approval (FL#) and Miami-Dade Notice of Acceptance (NOA) numbers issued product by product, so check the NOA for each series. They are tested to TAS 201 (large missile impact), TAS 202 (cyclic wind pressure), and TAS 203 (water infiltration) — the same standards applied to PGT WinGuard.

ESW Windows and Doors: Product Lines & DP Ratings
| Product | Typical DP Rating | Best For | Notes |
|---|---|---|---|
| Aluminum Single-Hung | DP+40 to DP+55 | Most South Florida homes, coastal areas | Most-installed ESW residential product |
| Aluminum Sliding Window | DP+35 to DP+50 | Horizontal openings, bedrooms | Available in 2-lite configurations |
| Aluminum Fixed/Picture | DP+50 to DP+65 | Large openings, views | Higher DP achievable in fixed configuration |
| Aluminum Casement | DP+45 to DP+55 | Maximum ventilation | Tightest seal when closed |
| Sliding Glass Door | DP+30 to DP+45 | Patio access, coastal replacement | 2-lite and 3-lite available |
DP ratings vary by window size configuration. Verify the specific NOA for your size. ESW's typical residential DP ratings meet or exceed Florida Building Code requirements for Broward, Miami-Dade, and Palm Beach.

ESW vs. PGT WinGuard: Performance Compared
The core question most homeowners ask: does any price difference between brands reflect a real performance gap, or just brand premium?
For standard residential sizes in inland and near-coastal locations, ESW and PGT WinGuard perform comparably. Both pass the same TAS testing. Both offer HVHZ-rated lines — verify the NOA for your product. Both qualify for the same windstorm insurance discounts. A properly installed ESW window will protect your home as effectively as a PGT during a hurricane.
Where a gap can appear: at the extreme end. Design pressure ratings vary by product, size and configuration — check the specific Miami-Dade NOA or Florida Product Approval for each unit. That matters most for very large window sizes (especially fixed/picture windows over 60" wide) and for true oceanfront installations with continuous salt spray exposure.
For most South Florida homes — Broward County suburbs, inland Miami-Dade, Palm Beach communities — this difference is theoretical. ESW delivers equivalent protection — compare quotes on your sizes.

ESW Verified Prices vs. PGT WinGuard (Supply-Only)
| Product | ESW MultiMax (supply-only) | PGT WinGuard | Price date |
|---|---|---|---|
| Single hung (ES-MX1000), 36" × 36" | $461 | Quoted per project | Verified Jul 9, 2026 |
| Single hung (ES-MX1000), 30" × 54" | $541 | Quoted per project | Verified Jul 9, 2026 |

ESW prices are verified supply-only (white finish, clear laminated impact glass; installation, permit and tax are separate). PGT is quoted per project, so we do not claim a fixed saving: request PGT and ESW quotes on the same sizes and compare. Both offer HVHZ-rated lines (verify the NOA for your product) and qualify for the same insurance credits.
Exact number for your opening: build your ESW window or door at your width and height and the verified factory-direct price and drawing appear on the page — no sales visit.
Insurance Discounts: ESW Qualifies for the Same Credits as PGT
Because ESW's impact lines carry Miami-Dade NOA approvals (check the number for your product), an ESW installation qualifies for the same windstorm insurance discounts as PGT WinGuard. The insurance company does not pay a premium for the PGT name — it credits the approved opening protection.
- • Opening protection credit: Florida law requires insurers to offer wind-mitigation discounts on the hurricane-wind portion of the premium, documented with form OIR-B1-1802; the amount depends on the insurer and the home. Same rules as PGT.
- • Annual savings: varies by insurer, home and existing mitigation features — ask your agent for a quote
- • Payback period: depends on your project cost and your premium
- • Required: Licensed wind mitigation inspector after installation
Who Should Choose ESW?
ESW is the right choice if:
- Your home is inland or near-coastal (not directly on the ocean)
- You want an HVHZ-designed impact line (NOA verified per product) with a verified price for your size
- You're replacing standard residential windows (single-hung, sliders, casement)
- Budget matters but you won't compromise on HVHZ certification
- You're planning to sell — ESW is a recognized South Florida brand
- You want to see a real price for your size online before ordering
Choose PGT WinGuard instead if:
- Your home is directly on the ocean or Intracoastal (within 500 feet)
- Your very large openings need a design pressure you can confirm in a PGT NOA at your size
- You're in a luxury market where brand recognition affects value
- You want a limited lifetime warranty on vinyl frames (WinGuard Vinyl)
- You need more than two frame colors
Choose Mr. Glass instead if:
- Budget is the primary driver and you want a value line
- You're protecting a rental property or secondary structure
- Your home is far inland (>3 miles from coast)
Frequently Asked Questions: ESW Impact Windows
Who makes ESW impact windows?
ESW stands for ES Windows — the trade name of E.S. WINDOWS, LLC. Its Elite (E-Line) catalog states more than 40 years as a window and door manufacturer and specifies high-performance Low-E glass options by Tecnoglass. The residential range spans the Elite, MultiMax and Prestige lines. Windows Stock Market sells ES Windows products in South Florida; ask for the current Notice of Acceptance for the exact series you are permitting.
Does ESW qualify for Florida insurance discounts?
Yes. ESW's impact lines are designed for HVHZ use — check NOA numbers product by product — and an approved, permitted ESW installation qualifies for wind-mitigation credits after a licensed wind mitigation inspector verifies installation. Florida law requires insurers to offer wind-mitigation discounts on the hurricane-wind portion of the premium, documented with form OIR-B1-1802; the amount depends on the insurer and the home.
What is the difference between ESW and PGT WinGuard?
Both brands offer HVHZ-rated lines that meet South Florida code requirements — verify the NOA for your product. PGT WinGuard offers more product configurations, a limited lifetime warranty on WinGuard Vinyl frames (ESW's standard Duranar finish carries a 10-year warranty; other coverage varies by component), and more frame colors. Design pressure ratings vary by product, size and configuration — check the specific Miami-Dade NOA or Florida Product Approval for each unit. Price depends on size and series, so compare quotes on your sizes. For most inland South Florida homes, ESW delivers equivalent real-world protection.
What is ESW's warranty?
ESW's standard Duranar (AAMA 2605) paint finish carries a 10-year warranty; other coverage varies by component. Ask for the written warranty for your exact series. By comparison, PGT, founded in 1980, offers a limited lifetime warranty on WinGuard Vinyl frames; glass and finish coverage differ. Manufacturer warranties cover manufacturing defects, not damage from improper installation or added window film.
Is ESW good for coastal Florida homes?
ESW includes corrosion-resistant hardware as standard, with stainless steel available for coastal installations, and its impact lines are designed for HVHZ use — check NOA numbers product by product. For oceanfront homes directly on salt water (within 500 feet of the ocean), compare the NOA ratings and finish warranties of ESW and PGT WinGuard at your exact sizes. For Intracoastal or bay-front homes, ESW is a strong option at a lower price.
Where can I buy ESW impact windows at a discount?
Windows Stock Market lists in-stock ESW units, priced per listing. In-stock availability also avoids the factory wait — custom orders typically take 4–8 weeks.
