Frequently Asked Questions
The ES-PI312T is a thermally-broken aluminum project-in operable system in ES Windows's Commercial & Architectural Series, built on a slim 2-3/4-inch profile depth with a 3-1/4-inch visible line. It is available in project-out, casement/tilt-turn, and top-hung hopper configurations, plus a light/accessible ES-PI312T LA variant, and uses concealed hinges for a clean look. We install the ES-PI312T on commercial and architectural projects that want a versatile, thermally-broken operable window in a narrow profile.
The ES-PI312T profile we have does not list a large-missile impact rating or a Miami-Dade NOA; it is described as a thermally-broken architectural operable window with insulated and insulated-laminated glass options. The Commercial & Architectural Series carries both non-impact architectural systems and separate HVHZ impact systems, so for an opening inside the High Velocity Hurricane Zone we would direct you to an impact-rated ES Windows option such as the ES-PA220, which carries large- and small-missile impact in some configurations. We confirm the correct impact-rated product and approval for your jurisdiction before quoting.
With the SB70 low-E argon-filled packages, the ES-PI312T reaches a U-factor of 0.36 with a condensation resistance (CR) of 60, and SHGC values as low as 0.11 to 0.12 with solargray glass. The standard clear insulated argon make-ups carry a U-factor around 0.49 with a CR of 47, while tinted options like azuria and solargray lower the SHGC and visible transmittance. We help you choose from the full range of insulated and insulated-laminated make-ups to balance heat gain, daylight, and budget.
The ES-PI312T is offered in a wide range of insulated and insulated-laminated argon-filled make-ups, including clear, solargray, solexia, and azuria tints, plus SB70 low-E options and laminated PVB units for added sound and security. For example, a 1/4 SB70 + 1/2 argon + 1/4 clear unit is rated U 0.36, SHGC 0.18, VT 0.40, while a 5/16 solargray laminated unit drops the SHGC and visible transmittance for high solar-control needs. We walk you through which make-up best fits the project's energy and glare goals.
The ES-PI312T is available in anodized, painted, and wood-imitation finishes, and uses concealed hinges for a clean appearance. It offers ADA-compliant operating-force handle options, and the light/accessible ES-PI312T LA variant is available for openings with accessibility requirements. We review the finish and handle options so the window fits the building's design and use.
Installed pricing for the ES-PI312T depends on the configuration (project-out, tilt-turn, or top-hung hopper), the size, the glass make-up you select, the finish, and the condition of the existing opening, so there is no single price. As your installer, Armor Pro handles measurement, any required permitting, and code-compliant installation. Contact us for a free, no-obligation estimate and we will measure your openings and quote the ES-PI312T.
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.
