Frequently Asked Questions
The ES-45T is the Prestige line's thermally broken aluminum balcony slider, built on a 4.5-inch frame in X, XX, and OXXO panel configurations. The thermal break makes it well suited to balcony and patio openings where energy performance matters in our South Florida heat. We install it as the architectural-grade slider in the Prestige series, and because it shares a Florida Product Approval and install manual with the companion ES-46T swing door, the two can be combined in one assembly mixing sliding and swing operation.
Yes, the ES-45T is an impact-rated door in ES Windows's premium Prestige line, which is built as an architectural-grade impact platform. It shares its Florida Product Approval with the companion ES-46T swing door. As your installer, we confirm the specific approval number and that it matches your jurisdiction's requirements at the time of your permit.
The ES-45T installs to a maximum of 48 by 96 inches across its single (X), OXXO, and O/XX (with sidelite or transom) configurations, each rated to a design pressure of +70/-70 psf. Design pressure is the wind load the door is engineered to resist, and the rating your opening must meet depends on its size and wind exposure. We confirm the exact design pressure your specific door needs at quote.
The ES-45T standard glazing is a 1-inch insulated unit (1/4-inch heat-strengthened + 1/2-inch spacer + 1/4-inch heat-strengthened). Its clear insulated package is rated at a U-factor of 0.39 and SHGC of 0.20, while the Solarban 70 (SB70) Low-E version comes in at U-factor 0.43 and SHGC 0.21. Combined with the door's thermal break, these packages help control heat gain, and we'll recommend the right one for your home's sun exposure.
The ES-45T is available in anodized, painted, and wood-grain finishes, all offered as standard in the Prestige line. Sill options include a standard sill, low sill, and ADA sill, with sidelite and transom frame types available, plus a multipoint lock, optional ADA threshold, and high bottom rail. The glass can also be ordered with painted, serigraphy, or digital-printed finishes, and we'll go over these options so the door matches your project.
Installed pricing for the ES-45T depends on the size, the X, XX, or OXXO configuration, the glass package, the finish and sill options, and the condition of the existing opening, so there is no single price. The Prestige line is the premium architectural-grade tier, and the ES-45T's thermal break and wood-grain finish options sit at the top of the ES Windows range. As your installer, Armor Pro handles measurement, permitting, and installation, and we'll give you a free, no-obligation estimate.
Yes. Prestige is ES Windows's premium aluminum impact line and carries Miami-Dade NOAs across its windows and doors for HVHZ use in Miami-Dade and Broward, including thermally broken variants. Exact design pressures depend on the product and opening size, which we confirm against your address before ordering.
Prestige is built around large-format and statement openings: the PSD5030 pivot door (a 2024 Glass Magazine award winner), the FX3050 folding door with panels up to roughly 8 by 16 feet, the 16-panel BF5010T bi-fold, and impact sliding glass doors. These are the openings homeowners want to disappear, and Prestige is engineered to make them disappear while keeping an HVHZ impact rating. We size and configure the door system to your opening during the consultation.
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.
