Frequently Asked Questions

The Legacy 525 (LG-525) is a thermally-broken aluminum swing (French) door designed for high-end architecture, built on a 4-1/2-inch frame with a slim 3-3/4-inch sightline and advanced locking and sealing technology. It is part of ES Windows's Legacy line, which leads on thermal performance and premium architect-spec hardware. We install it as an elegant in-swing or out-swing patio door where clean sightlines and tight sealing matter.

No. The Legacy 525 has a non-impact (NI) rating and is not HVHZ approved, because Legacy is a thermal-performance line rather than a hurricane line, so we do not install it in the High Velocity Hurricane Zone of Miami-Dade or Broward. If you need an impact-rated swing door, ES Windows's Prestige and Elite families carry the missile-impact ratings, and we can quote those instead. We confirm the rating at quote so there is no ambiguity.

The Legacy 525 is offered as a single thermal swing door up to a maximum of 48 by 120 inches and as a double swing door up to 96 by 120 inches, allowing for tall openings up to 10 feet high. It accepts 1-inch, 1-1/4-inch, and 1-3/16-inch insulated glass plus 1-9/16-inch double-insulated glass. We size the door to your opening and confirm the configuration when we measure for your quote.

The Legacy 525 uses premium hinge hardware: Dr. Hahn surface hinges for out-swing and Hager mortise hinges for in-swing. It offers a standard lock or five multipoint lock options, with a lever handle or offset bar pull and an optional thumb-turn, and hardware finishes in black or satin. We help you choose the swing direction and locking configuration that fits your entry.

With 1-inch insulating glass, the Legacy 525 reaches a U-factor of 0.27, reflecting the thermally-broken aluminum construction that defines the Legacy line. Frame finishes include anodized, painted (AAMA 2605), woodgrain, champagne bronze, and white. We help you match the finish to your home and pick the glass package that meets your energy goals.

Installed price depends on whether you choose a single or double configuration, the size of the opening, the glass package, the finish, the hardware and locking options, and the condition of the existing opening, so there is no flat rate. Premium Dr. Hahn and Hager hinge hardware and multipoint locking also factor into pricing. Armor Pro provides a free estimate so you get exact numbers for your project.

No. Legacy is ES Windows's thermally broken aluminum architectural line, and it is positioned for thermal performance and design rather than storm protection; most of the line carries a non-missile rating and no Miami-Dade NOA. For a project in the High Velocity Hurricane Zone we spec ES Windows's aluminum impact lines (Prestige or Elite) for the openings that need to meet impact code, and reserve Legacy for where its energy and aesthetic strengths fit.

Legacy is built on a fully thermally broken aluminum platform, and the LG-225 fixed and curtain-wall system reaches a U-factor of 0.19 with standard dual-pane argon-filled insulated glass, which is a strong number for an aluminum window. In our climate, solar-heat control (SHGC) usually matters as much as U-factor, so we look at both when deciding where Legacy makes sense versus an impact line.

ES Windows is the residential and light-commercial fenestration brand of Tecnoglass Inc. (NYSE: TGLS), and the products are manufactured at the company's complex in Barranquilla, Colombia. What makes the brand unusual is that the parent makes its own architectural glass and aluminum extrusions and then assembles the finished windows and doors in-house, so a single company stands behind the whole assembly rather than buying glass and frames from outside suppliers. We install and service ES Windows products throughout South Florida.
