ES Windows ES-U4225 Curtain Wall

No. ES Windows designed the ES-U4225 for the Latin American market, and it is not marketed in the US, which is why it does not appear in the US brochures. For a US-market unitized curtain wall, ES Windows offers the ES-U3725, a 3-3/4-inch system built for the USA market. If you are planning a US commercial facade, we'll steer you to the US-market ES Windows curtain wall systems instead.

Because the ES-U4225 is a Latin American market system that is not marketed in the US, we do not present it as a system for permitting on a South Florida project. For a Miami-Dade or Broward facade you need a US-market system with current Florida product approval or a Miami-Dade NOA, such as ES Windows's US-market curtain walls. We'll confirm the right system and the documentation your jurisdiction requires before permitting.

Both are unitized aluminum curtain walls in ES Windows's Commercial & Architectural Series, but the ES-U4225 uses a deeper 4-1/4-inch system depth while the ES-U3725 is 3-3/4 inches. The bigger practical difference is the market: the ES-U4225 is built for the Latin American market and not marketed in the US, whereas the ES-U3725 is offered for the USA market. For US commercial work we'd direct you to the US-market ES-U3725 rather than the ES-U4225.

A unitized curtain wall like the ES-U4225 is assembled and glazed into finished panels off-site, then hoisted and locked into place on the building, rather than being built up piece by piece on the facade. This generally speeds field installation and tightens quality control versus a stick-built system. The ES-U4225 uses a 4-1/4-inch system depth, though as a Latin American market product it is not one we install on US projects.

Curtain wall systems like the ES-U4225 are engineered per project, so panel sizes and design pressure follow the building's height, wind exposure, and anchoring rather than a single fixed maximum. As a Latin American market system that is not marketed in the US, the ES-U4225 is not a product we scope for US openings. If you have a US commercial facade, contact Armor Pro and we'll direct you to a US-market ES Windows curtain wall and provide a free estimate.

This is ES Windows's house-brand catalog for commercial, condo, and mid- to high-rise architectural work, distinct from the residential tier lines. It covers aluminum storefront, stick and structural-silicone-glazed curtain wall, pre-glazed impact window wall, project-in and project-out operable windows, and commercial sliding and lift-slide doors. We reference it for light-commercial and architectural-spec projects rather than standard home replacement.

The U.S.-market impact systems are the ones that carry real HVHZ ratings: the ES-8860 window wall is tested to plus and minus 150 psf, the ES-6000/6100 sliding door reaches plus 120 / minus 135 psf with multiple Miami-Dade NOAs, and the ES-7500/7600 window wall and several others carry large- and small-missile certification. Some of the metric storefront and curtain-wall framing systems are Latin-American architectural products without Florida approval, so we verify approval status before specifying any of them on a Florida job.

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.
