The ES-MX4000 is MultiMax's sliding glass door, the value-tier patio slider for projects where price leads. It comes in OX, XO, OXO, and OXXO on a two-track frame up to four panels at 5-3/8 inches deep, with the Vitro Solarban 70 Low-E glass package available when energy performance matters. It is LMI impact-rated for the HVHZ, so it delivers a code-compliant patio opening at the lowest cost in the ES Windows slider range.
Armor Pro specs the MX4000 on budget-driven residential replacements and entry-level multifamily where the opening is a standard two-track size. When a project needs more panels, more tracks, or a pocket configuration, the Elite EL400 is the step up; for a thermally broken balcony door, the Prestige SGD2020T. The MX4000 is the answer when the brief is a straightforward impact slider at the best price.

Frequently Asked Questions
The ES-MX4000 is the Multimax value-tier aluminum impact sliding glass door, built on a two-track frame up to four panels in OX, XO, OXO, and OXXO configurations at 5-3/8 inches deep. It is the lowest-cost slider in the ES Windows range, so we spec it for budget-driven residential replacements and entry-level multifamily where the opening is a standard two-track size. If a project needs more panels, more tracks, or a pocket configuration, the Elite EL400 is the step up, and for a thermally broken balcony door we recommend the Prestige SGD2020T.
Yes. The ES-MX4000 is Large Missile Impact (LMI) rated and carries Miami-Dade NOA 25-0128.05, listed as expiring March 18, 2029, with an earlier NOA 21-0408.07 also on record. That approval covers the High-Velocity Hurricane Zone of Miami-Dade and Broward counties. As your installer, we confirm the current NOA is on file and matches your jurisdiction at the time of your permit.
The ES-MX4000 installs to a maximum panel size of 48 by 108 inches and is rated to a design pressure of +80/-103 psf in its sliding-glass-door configuration. Design pressure is the wind load the door is built 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-MX4000 uses a 5/16-inch laminated glass make-up (1/8-inch heat-strengthened + 0.09 PVB + 1/8-inch heat-strengthened) and is available with the Vitro Solarban 70 Low-E coating for better energy performance. The standard package is rated at a U-factor of 1.02 and an SHGC of 0.30. We will walk you through whether the Solarban 70 upgrade makes sense for your home's sun exposure and budget.
The ES-MX4000 is offered in white powder coat and bronze powder coat frame finishes, with an involute handle and optional frame reinforcement as hardware. A screen is available, and the glass can be ordered as PVB laminated with the Solarban 70 coating option. We'll go over the finish and hardware choices so the ES-MX4000 matches your home's look.
Installed pricing for the ES-MX4000 depends on the opening size, the OX, XO, OXO, or OXXO configuration, the glass package, the finish, and the condition of the existing opening, so there is no single price. The Multimax line is positioned as the value tier, delivering an HVHZ code-compliant impact slider at the lowest cost in 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. Multimax is ES Windows's value-tier aluminum impact line, but it carries dual large-missile and small-missile certification across the catalog and publishes current Miami-Dade NOAs, so it is genuinely HVHZ-eligible. It is not a de-rated product; some models actually post very high design pressures, such as the MX1500 fixed window rated to 140 psf negative. We confirm the rating against each opening before ordering.
Small-missile impact (SMI) certification is what qualifies a window for installations above roughly thirty feet, where the design assumes smaller wind-borne debris at height. Most value-priced lines cannot go on mid- and high-rise openings, but Multimax can, which makes it useful on low-rise condo and multifamily work as well as budget single-family jobs. We check the building height and exposure to confirm the SMI configuration applies.
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.
