Impact protection, built for South Florida
The ES-SGD2020T is the Prestige slider built for energy as much as protection. It is thermally broken aluminum on a 4.5-inch frame, in X, XX, and OXXO configurations, with an ADA-compliant threshold, an optional high-bottom-rail, and multipoint locking. The thermal break is the point: on a large glass opening, a bare-aluminum frame conducts heat and runs up the cooling bill, while the broken frame holds the energy numbers down, which matters on a balcony or patio wall that is mostly glass.
Armor Pro specs the SGD2020T on impact balcony and patio openings where the owner cares about the energy bill and wants ADA-level threshold access. For the largest moving-glass spans or a folding wall, the FX3050 and the bi-fold take over; for a standard non-thermal slider at a lower price, the Elite EL400 covers the same opening.

Frequently Asked Questions
The ES-SGD2020T is the Prestige thermally broken balcony door, built on a 4.5" aluminum frame in X, XX, and OXXO panel configurations for residential balcony and patio openings. The thermal break is the whole point: on a mostly-glass opening, a bare-aluminum frame conducts heat and drives up cooling costs, while the broken frame keeps the energy numbers down. We spec this door when an owner wants impact protection on a balcony or patio wall but also cares about the energy bill.
Yes, the ES-SGD2020T is impact rated, and the thermally broken sliding configuration is rated to a design pressure of +105/-105 psf, which is strong for a slider this size. We'll confirm the specific approval and the DP that applies to your opening when we put together your quote.
A thermal break separates the inside and outside aluminum so heat can't conduct straight through the frame, which is important on a balcony or patio wall that is mostly glass. With the 1" insulated SB70 Clear glass package, the ES-SGD2020T tests at a U-factor of 0.34 and a SHGC of 0.216, both of which help hold down cooling costs in South Florida. We'll explain how the thermal break and glass choice work together when we quote your project.
The ES-SGD2020T can be ordered with 1" insulated glass (SB70 Clear at U 0.34, SHGC 0.216), 1-1/8" insulated glass, or a 1-5/16" insulated-laminated package. The insulated options pair with the thermally broken frame to maximize energy performance on large balcony and patio openings. We'll help you choose the glass that best fits your protection and efficiency goals.
Yes. The ES-SGD2020T offers an ADA sill and an ADA flush sill in addition to the standard no-riser sill, giving you a low, easy-to-cross threshold on the balcony. It can also be configured as a two-, three-, or four-track slider or as a 90-degree or 135-degree corner unit, with adjustable rollers and multipoint locking standard. We'll set the sill and configuration to match your floor and layout.
Installed pricing for the ES-SGD2020T depends on the size, the panel configuration, whether you choose a corner layout, the glass package, the sill option, and the existing opening. Because it is a custom thermally broken door, every job is priced on its own. Armor Pro gives you a free estimate after measuring the opening and confirming the configuration.
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.
