Authorized ES Windows installer
Elite achieves up to 220 mph design-wind on engineered configurations — clears any HVHZ exposure category. The vertical integration of glass + frame manufacturing is what enables the rating ceiling no other brand can match.
Tecnoglass S.A. (TGLS) tempers glass, laminates impact-rated assemblies, and extrudes the aluminum frames in-house — the only major South Florida impact brand operating the entire supply chain under one roof.
Multimax ships sliding glass doors over 10' wide and picture windows over 6' tall as standard configurations. Custom architectural specs the typical luxury build calls for ship without engineering-special NOA reviews on most cases.

TL;DR
ES Windows is manufactured by Tecnoglass S.A. (NYSE: TGLS) — a vertically-integrated architectural-glass company founded by the Daes family in Barranquilla, Colombia in 1984. The 'ES' references the company's residential brand identity. Tecnoglass produces both the laminated impact glass AND the aluminum extrusions in-house, which is why ES Windows can hit wind ratings, sightline profiles, and oversized-opening configurations no other brand in the SafeGuard portfolio matches.
ES Windows is the premium architectural-aluminum brand in the South Florida impact market — the line custom-home architects spec when the project calls for slim sightlines, oversized openings, and finish quality that reads as architectural-grade rather than production-grade. The brand is residential-facing for the parent company Tecnoglass S.A. (TGLS on the NYSE), one of the largest architectural-glass manufacturers in the Americas and the largest single supplier of hurricane-impact glazing to the South Florida high-rise market.
Vertical integration is the differentiator. Tecnoglass operates its own glass-tempering and laminating lines AND its own aluminum-extrusion mill — the only major impact-window brand serving South Florida that manufactures both halves of the assembly in-house. That's how the Elite line achieves 220 mph design-wind ratings and how Multimax can ship oversized opening configurations that PGT or CGI would have to engineer-special. Every ES product carries Miami-Dade NOA, the US headquarters operates from Miami, and the company is registered with the Miami-Dade Building Department as "E.S. Windows, LLC" for permit-pulling purposes.
SafeGuard installs the full ES line for luxury custom builds, coastal high-rise residential, and any project where the architect or homeowner has spec'd architectural-grade aluminum specifically. We typically pair ES Windows with PGT WinGuard on the same property when the budget calls for premium aluminum on the architectural-priority openings and value-tier vinyl on the back-of-house secondary windows.
Answer
Four active residential lines: Elite (premium architectural with the strongest wind ratings), Prestige (architectural casement/awning specialty), Multimax (oversized opening specialty for sliding-glass-doors and picture windows), and Legacy (the heritage product line for traditional architectural styles).
Elite is the flagship — premium architectural aluminum, slim sightlines, and the strongest wind-load ratings in the residential market (up to 220 mph design wind on engineered configurations). Best fit for luxury custom homes and high-rise residential where the architect specs the brand by name.
Prestige is ES's architectural casement and awning specialty — same impact rating as Elite, configured for the side-hinge and top-hinge operating styles common on Mediterranean and contemporary architectural styles. Slim sightlines and the heaviest extrusion in the casement/awning category.
Multimax is ES's oversized-opening specialty — sliding glass doors over 10' wide, picture windows over 6' tall, and pocket configurations that disappear into the wall. The vertical-integration story shines here: Tecnoglass can engineer custom configurations that no other brand can ship without a fully-custom NOA review.
Legacy is ES's heritage line — designed for traditional architectural styles where the slim modern sightline isn't the goal. Heavier visual frame profile, pre-1980s aesthetic, all the same HVHZ certifications.

Answer
Three reasons stack: vertical integration enables configurations that no competitor can ship, the 220 mph design-wind ceiling clears any HVHZ exposure category, and the architectural-grade aluminum finish range matches the spec's the typical luxury custom build calls for.
Configuration ceiling. Tecnoglass owns the entire supply chain — glass tempering, lamination, aluminum extrusion, frame assembly. When an architect calls for a 12' wide × 9' tall glass wall with a single-pane unbroken aesthetic, no fastener visible from the interior, and a custom anodized finish, ES Windows can engineer + fabricate that. PGT and CGI typically can't without a fully-custom NOA review process that adds 4-8 weeks to lead time.
The wind-rating ceiling matters on coastal high-rise. South Florida coastal high-rise residential is the most-exposed installation category in the country — Exposure D applied to 200+ ft elevations puts pressures on the windows that interior buildings will never see. The 220 mph rating on Elite covers any exposure category; PGT and CGI typically max at 175 mph which is enough for most properties but not enough for extreme high-rise spec.
Architectural finish range. Anodized champagne, anodized bronze, custom RAL-color powder-coat, two-tone (different exterior and interior finish) — all available. PGT and CGI offer a tighter palette; ES matches the spec's a custom architect typically writes.

Yes — ES Windows is the premium architectural-aluminum brand in the South Florida impact market, manufactured by NYSE-listed Tecnoglass (TGLS). The brand carries Miami-Dade NOA across all four product lines (Elite, Prestige, Multimax, Legacy), achieves up to 220 mph design-wind ratings on engineered configurations (the strongest in residential), and is the largest single supplier of hurricane-impact glazing to the South Florida high-rise market. Architects spec it by name on luxury custom builds. The trade-off vs PGT WinGuard is the lead time (8-12 weeks for custom configurations vs 4-8 for PGT stock) and the price point (premium architectural-tier).
'ES' is the residential-brand identity for the parent company Tecnoglass — the company brands its consumer-facing residential window products as 'ES Windows' (sometimes written 'E.S. Windows'). The Miami-Dade Building Department lists the registered entity name as 'E.S. Windows, LLC' for permit-pulling purposes. Tecnoglass S.A. is the legal Colombia-based parent; ESWindows.com is the residential-product website.
ES Windows is manufactured by Tecnoglass S.A. (NYSE: TGLS), founded by the Daes family — brothers José Manuel Daes and Christian Daes — in Barranquilla, Colombia in 1984. Tecnoglass went public on the NYSE in 2013 and is one of the largest architectural-glass manufacturers in the Americas. The company is publicly traded but the Daes family retains a controlling ownership stake. US operations are headquartered in Miami, Florida. The vertically-integrated business model — glass tempering + lamination + aluminum extrusion all in-house — is the strategic differentiator.
ES Windows installation in South Florida runs roughly $900–$2,500 per opening installed depending on product line, size, glass tier, and finish. Premium architectural-tier Elite and Prestige configurations cost ~30-50% more than equivalent PGT WinGuard Aluminum. A whole-home ES Windows install on a 2,500 sq ft custom home typically lands between $50,000 and $120,000 with permit. Multimax oversized-opening configurations price separately because of the engineering-custom NOA work.
Elite is the flagship architectural-aluminum line — slim sightlines, 220 mph design-wind ceiling, single/double hung + sliding + picture configurations. Prestige is the casement and awning specialty — heavier extrusion, side-hinge and top-hinge operating. Multimax is the oversized-opening specialty — sliding glass doors over 10' wide, picture windows over 6' tall, pocket configurations. Legacy is the heritage product line for traditional architectural styles — wider visible frame, pre-1980s aesthetic, same HVHZ ratings. We pair the line to the architect's spec or the project's wind-exposure requirement.
Yes — every ES Windows product carries a current Miami-Dade Notice of Acceptance. Miami-Dade Building Department lists the manufacturer as 'E.S. Windows, LLC' for permit-pulling lookups. The NOA paperwork is comprehensive across Elite, Prestige, Multimax, and Legacy product lines. Tecnoglass also holds Florida Product Approval certifications for non-HVHZ jurisdictions, but the Miami-Dade NOA is the gold-standard impact certification and is accepted everywhere in Florida.
Lead time is the variable to plan around. Stock Elite + Prestige configurations ship in 6-8 weeks; Multimax oversized openings + custom finish requests run 8-12 weeks; engineering-custom configurations can run 12-16 weeks. Permit review on the South Florida side runs 21-50 business days in parallel with manufacturer lead time. Once permits are pulled and product arrives, the actual installation on a custom home runs 3-7 days depending on complexity.
