Mr. Glass vs PGT vs ESW vs CGI Impact Windows — 2026 Comparison

When homeowners in South Florida start researching impact windows, three names come up consistently: PGT, ESW (ES Windows), and Mr. Glass. All three are legitimate, Florida-approved manufacturers with products installed in thousands of homes across Miami-Dade, Broward, and Palm Beach counties. But they are not the same, and the differences matter depending on your home, your budget, and what you prioritize.

This guide breaks down exactly how PGT, ESW, and Mr. Glass compare across every category that matters — so you can make an informed decision instead of just taking a contractor's word for it.

About Each Brand

PGT Windows

PGT (PGT Innovations) was founded in 1980 in Florida and is widely considered a pioneer of impact-resistant windows in the state. For decades, PGT has been the most recognized impact window brand in Florida and is deeply integrated into the local contractor and dealer network.

PGT's flagship product line for residential use is WinGuard, which includes single hung, horizontal roller, casement, and sliding glass door configurations. They also offer EnergyVue and PremierVue lines at higher price points with enhanced energy performance.

PGT is owned by MITER Brands, with manufacturing in Florida and a large distribution network across the state.

ESW — ES Windows (Tecnoglass)

ESW is part of Tecnoglass (NASDAQ: TGLS), which manufactures in a vertically integrated complex of more than 5 million square feet in Colombia. ES Windows has gained market share in Florida by offering a strong standard package at competitive prices against domestic competitors.

ESW's impact lines are designed for HVHZ use; check NOA numbers product by product, because design pressure ratings vary by product, size and configuration. ESW includes corrosion-resistant hardware as standard, with stainless steel available for coastal installations, and low-E glass is available from all three brands; whether it is standard or an upgrade depends on the product line and the quote.

Mr. Glass

Mr. Glass Doors & Windows is a South Florida manufacturer (Medley, FL) that produces impact windows and doors for residential and commercial applications across South Florida. Their MG product line covers single hung windows, horizontal rollers, French doors, and sliding glass doors.

Mr. Glass is a regional manufacturer rather than a national or international brand. They are positioned as a value-oriented option for homeowners who want Florida-approved impact products at competitive prices. Ask for the written warranty and the NOA for each product — that is how you confirm the exact approval for your opening.

How They Compare: Category by Category

Hurricane Protection and Design Pressure

All three brands offer HVHZ-rated lines for High-Velocity Hurricane Zones, including Miami-Dade and Broward counties — verify the NOA for your product. For standard residential applications, an approved unit from any of the three will provide legally compliant hurricane protection.

Design pressure ratings vary by product, size and configuration — check the specific Miami-Dade NOA or Florida Product Approval for each unit. No brand has one universal rating: the same series can carry a different rating at a larger size or in a different configuration, so compare ratings opening by opening.

The rating you need is set by the opening's location, height and wind exposure. Homes in higher-exposure locations, on upper floors, or in coastal areas should compare the NOA rating at the exact size quoted, not a brand average.

Glass Quality and Options

All three brands use laminated impact glass with a PVB or SGP interlayer. The glass holds together when broken rather than shattering, which is the defining characteristic of impact-rated glazing.

ESW has earned a strong reputation for optical clarity on their laminated units and offers a broad range of glass configurations including tinted, Low-E, and combination tint-with-Low-E packages. Low-E glass is available from all three brands; whether it is standard or an upgrade depends on the product line and the quote.

For homes near the ocean where UV protection and heat reduction are priorities, ask for Low-E on every quote so you compare the brands on the same glass.

Frame Materials

PGT offers both aluminum and vinyl frames. Their WinGuard Vinyl frames carry a limited lifetime warranty (glass and finish coverage differ), which is one of PGT's most competitive advantages for homeowners who prioritize longevity guarantees.

ESW and Mr. Glass primarily use aluminum frames. Aluminum provides higher design pressures and is the standard for high-rise and coastal construction in Florida. Vinyl is generally more energy-efficient in terms of thermal conductivity, but aluminum is better suited for large openings and high-wind-zone applications.

Pricing

Based on contractor pricing in South Florida in 2026:

• Mr. Glass is typically the most affordable option for standard configurations. Suitable for budget-conscious projects where code compliance is the primary goal.
• ESW offers competitive pricing with more features included as standard. The value-per-dollar ratio is strong: corrosion-resistant hardware is standard and the Duranar (AAMA 2605) finish carries a 10-year warranty.
• PGT is generally the most expensive of the three for equivalent configurations. The premium reflects brand recognition, the domestic manufacturing network, and certain premium series options.

Prices vary significantly by window size, style, and installation complexity. Always compare quotes based on identical specifications.

Lead Times and Availability

All three brands experience variable lead times depending on demand and season. In general:

• Mr. Glass: typically 4–8 weeks from order
• ESW: typically 4–8 weeks from order
• PGT: typically 4–8 weeks from order, longer during peak season

This is for new factory orders. If you find any of these brands in stock through Windows Stock Market, you can skip the wait entirely and have windows available for pickup same-day or next-day.

Warranties

• PGT: PGT, founded in 1980, offers a limited lifetime warranty on WinGuard Vinyl frames; glass and finish coverage differ.
• ESW: ESW's standard Duranar (AAMA 2605) paint finish carries a 10-year warranty; other coverage varies by component. A warrantied finish is particularly important for homes within 3 miles of saltwater.
• Mr. Glass: Ask for the written warranty for each product before you buy, and keep it with your permit documents.

Resale Value and Insurance

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. The brand itself does not affect the discount — what matters is that the product holds the required NOA or Florida Product Approval for your opening and is installed correctly with a permit.

For resale value, PGT's brand recognition may carry a slight marketing advantage in listings. However, ESW and Mr. Glass are equally recognized by building inspectors, insurance companies, and appraisers as fully compliant products.

Mr. Glass vs ES Windows: Which Is Better?

ESW (ES Windows) is the stronger package; Mr. Glass is the value line. Both sell impact products for South Florida code — verify the NOA for the exact unit — so the question is about package and price.

ESW ships from Tecnoglass with corrosion-resistant hardware as standard (stainless steel available for coastal installations) and a Duranar (AAMA 2605) finish backed by a 10-year finish warranty. Low-E glass is available from all three brands; whether it is standard or an upgrade depends on the product line and the quote. Ask for the same glass on both quotes. Verified supply-only examples for a 36" x 36" single hung: ESW MultiMax $461 (Jul 9, 2026) and Mr. Glass MG-200 $553.90 (Sep 21, 2026) — different products and glass, so price your own sizes before deciding.

Bottom line: pick ESW if you want more performance per dollar (especially for coastal homes where corrosion-resistant hardware and a warrantied finish matter). Pick Mr. Glass if the lowest fully-code-compliant price is the priority. Both are honest choices — this is a value trade, not a quality trade.

Mr. Glass vs PGT

This is the matchup homeowners ask about most, so here is the direct comparison. Both Mr. Glass and PGT sell impact products built for South Florida's HVHZ code — verify the NOA for your product — so for legal hurricane protection on an approved unit, they are equivalent. The real differences come down to price, frame options, and warranty.

• Price: Mr. Glass is the value line and PGT the premium line, but the gap depends on size, series and glass. Mr. Glass 36" x 36" single hung: $553.90 supply-only (Verified Sep 21, 2026); PGT is quoted per project — request a quote for your sizes.
• Frame options: PGT offers both aluminum and vinyl (vinyl WinGuard carries a limited lifetime warranty). Mr. Glass is aluminum only.
• Warranty: PGT, founded in 1980, offers a limited lifetime warranty on WinGuard Vinyl frames; glass and finish coverage differ. For Mr. Glass, ask for the written warranty for each product.
• Brand recognition: PGT is the most recognized impact brand in Florida, which can be a slight advantage at resale. Mr. Glass is a respected South Florida manufacturer based in Medley.
• Bottom line: For a standard residential replacement where the goal is code-compliant protection on a defined budget, Mr. Glass is the value line. For coastal homes, large openings, vinyl frames, or a lifetime warranty, PGT is worth the premium.

If you want the best package per dollar regardless of this matchup, ESW's corrosion-resistant standard hardware and verified factory-direct pricing make it the value leader — see the full table above.

PGT vs ESW

PGT and ESW sit at the top of the South Florida impact-window market, but they compete on very different strengths. PGT is the domestic incumbent — founded in 1980 in Florida, now part of MITER Brands, with the widest dealer and warranty-service network in the state, and the only one of the three offering vinyl frames with a limited lifetime warranty (the WinGuard vinyl line).

ESW, made by Tecnoglass in Colombia, competes with PGT on price (ask for both quotes on your sizes) while shipping with corrosion-resistant hardware as standard (stainless steel available for coastal installations) and a Duranar (AAMA 2605) finish with a 10-year finish warranty. Low-E and tint are available from both; whether they are standard or an upgrade depends on the product line and the quote.

Bottom line: choose PGT if brand recognition, vinyl-frame options, or the lifetime warranty matter for resale or peace of mind. Choose ESW if you want the best feature-set per dollar — especially for coastal or high-exposure homes where corrosion-resistant hardware and a warrantied Duranar finish pay off.

CGI vs Mr. Glass: What Changed in 2026

CGI is now part of the PGT portfolio (owned by MITER Brands); Sentinel is listed as a legacy line, and CGI keeps warranty documents for purchases made before Dec 15, 2025. That makes CGI vs Mr. Glass mostly a replacement question rather than a new-order decision. If you need to replace or add to a CGI installation, Mr. Glass, ESW and PGT are the options we can supply. Full details, warranty guidance and matching tips are in our CGI discontinued guide.

Choose ESW if: You want the most features per dollar, you want corrosion-resistant hardware as standard and a warrantied Duranar finish, or you have a larger home where better glass performance and coatings matter for energy savings.

Choose Mr. Glass if: You have a defined budget and need code-compliant impact protection on a defined budget, or you are doing a straightforward residential replacement in a standard-exposure South Florida location.
