VLX 80 Casement Window

VLX 80 Casement Window in San Antonio, TX | Juniper Windows San Antonio

The VLX 80 Casement Window is a side-hinged aluminum window built around one idea: you should see San Antonio, not your window frame. The profile measures just 1.97 inches wide, which means glass dominates the opening. That narrow sightline delivers something most homeowners don’t realize they’re missing until they see it: an unobstructed view of the Hill Country, your backyard oaks, or the downtown skyline.

Juniper Windows San Antonio is an authorized ViewLux installation partner, which means you get the factory product installed by a team that works with these exact windows every week. We measure, order, install, and stand behind the whole job from our San Antonio base. If you’re researching this window, call (903) 488-7019 and we’ll walk you through pricing, lead times, and what to expect.

Product Overview – VLX 80 Casement Window

Casement windows hinge on the side and crank outward, which gives them one advantage no sliding or double-hung window can match: full-panel ventilation. When a casement opens, the entire sash swings away from the frame. Air moves through the whole opening, not half of it. In a San Antonio climate where spring and fall evenings are the best weather all year, that matters more than most people expect.

The VLX 80 leans into the casement format with engineering that strips away visual bulk. The frame wall measures 0.079 inches and the face profile sits at 1.97 inches, which puts this window firmly in the ultra-narrow sightline category. That’s architectural territory. On a modern build in Pearl or a mid-century renovation in Terrell Hills, the thin aluminum frame reads as intentional, not budget-driven.

The material choice is equally deliberate. Aluminum doesn’t warp in humidity, doesn’t swell after a heavy Texas rain, and doesn’t rot the way wood eventually does in our Gulf Coast moisture. The tradeoff has always been thermal performance, which is why the VLX 80 runs a thermal break through the frame. More on that below. The short version: you get the strength and slimness of aluminum without the cold-frame problem.

Who buys this window? Homeowners replacing failed builder-grade windows, architects specifying for custom homes in Alamo Heights, and commercial builders who need spans that vinyl can’t handle. The casement format also works well in kitchens and bathrooms where a crank-out sash is easier to operate over a counter than a sliding panel.

Technical Specifications

Here’s the VLX 80 Casement Window on paper. These numbers tell the engineering story if you know what to look for, and we’ll translate the important ones below.

• Frame wall thickness: 0.079 inches of extruded aluminum
• Profile width (face dimension): 1.97 inches, achieving the ultra-narrow sightline
• Glass options: Clear, Frosted, Low-E, Tempered, Laminated
• Finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, Teak Wood
• Screen options: Fixed Screen, Retractable Screen
• Sill options: Standard Sill, Low-Profile Sill
• Thermal performance: Thermal break technology, NFRC-rated
• Installation standard: AAMA 2400/2410 compliant
• Impact option: Laminated glass available for wind-borne debris zones
• Wind load: Rated for San Antonio regional climate requirements

The low-profile sill is worth a second look if you’re replacing old windows and want a cleaner transition at the bottom of the opening. It reduces the height difference between the interior floor and the sill face, which matters for accessibility and for modern design preferences.

Performance Features

Thermal Efficiency – The VLX 80 uses a thermal break that separates the interior and exterior aluminum faces. Without it, aluminum conducts heat straight through the frame. With it, the window earns NFRC energy performance ratings that matter when your AC runs nine months a year in San Antonio. Pair with Low-E glass for the best numbers.

Acoustic Performance – Laminated glass is the quiet option. The interlayer between the glass panes dampens vibration, which reduces traffic noise from Loop 410, flight paths from SAT, and the general hum of a growing city. If your bedroom faces a busy street in Stone Oak or Leon Valley, this is the glass option worth the added cost.

Airtightness & Weather Seal – The casement format has a structural advantage here. When you crank the sash closed, it compresses against the weather stripping around all four sides. That compression seal is harder to achieve on sliding windows, and it’s one reason casement windows typically post better airtightness test results. For San Antonio, that means less dust intrusion during dry windy months and fewer drafts in January.

Waterproofing – The VLX 80 is engineered for managed water drainage. The sill design channels water that penetrates the outer seal to weep to the exterior rather than into your wall cavity. Combined with proper installation sealing, it’s built for the gully-washers we get in May and September.

Wind Resistance – San Antonio sits at the edge of the Texas wind corridor, and storm season drives the point home. The VLX 80 is wind-load rated for regional requirements, and the laminated glass option moves it into impact-resistant territory for homeowners who want the extra layer of protection without installing full hurricane systems.

Security & Hardware – Casement hardware locks at multiple points along the frame, not at a single latch. Because the sash hooks into the frame at the lock points rather than pressing against a spring mechanism, it’s harder to pry open from the outside. The crank mechanism also means you can leave windows open a few inches without creating an easy entry point.

Color & Glass Options

The VLX 80 comes in six finishes: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, and Teak Wood. Each fills a different design role in San Antonio homes.

Premium Black is the current architectural standard for modern builds, especially in areas like Dignowity Hill and Tobin Hill where dark frames against white stucco create that sharp contrast. Pure White is the practical choice for traditional San Antonio homes with cream or beige exteriors. Anodized Silver is a true aluminum look, honest to the material, that works on mid-century homes and commercial storefronts. Bronze has been the Texas default for decades and still reads well on ranch-style homes. Champagne reads warmer than silver and bridges the gap between modern and traditional. Teak Wood gives you the look of wood trim without the maintenance.

On glass, the decision usually comes down to three factors: energy performance, privacy, and safety. Low-E is the energy default for most San Antonio projects because it cuts solar heat gain. Frosted makes sense for bathrooms and side yards with close neighbors. Tempered is code-required in many door-adjacent and low-sill applications. Laminated adds impact resistance and acoustic damping. Clear is available, but it does the least work in a city with our August sun.

Installation by Juniper Windows San Antonio in San Antonio

Window installation in San Antonio is not a casual trade. Our climate cycles through triple-digit summer heat, flash floods, occasional freezes, and spring hailstorms, all of which test the seal between your window and your wall. The quality of that seal determines whether the window performs for ten years or leaks in three.

Our process starts before the window arrives. We measure the rough opening, check the framing for rot or shifting, and flag issues before the order goes in. When the VLX 80 arrives, we set the frame level, plumb, and square, which matters more on casement windows than any other type. A casement that’s set a quarter-inch out of square will sag on its hinges and fail the seal.

We install to AAMA 2400/2410 standards, which govern the proper installation of windows in both new construction and retrofit applications. Every perimeter joint gets AAMA 812 low-expansion foam sealant, which fills gaps, adheres the frame to the opening, and stops air and water movement at the transition. After the window is set and sealed, we water-test, check operation, and clean up the site.

One thing you should know: most manufacturer warranties on premium windows are void if the installation fails to meet the manufacturer’s published standards. Authorized partners exist because the manufacturer trusts that installation team with the product. Juniper Windows San Antonio carries that authorization from ViewLux, and we install for warranty compliance, not just for the close of the job.

Frequently Asked Questions – VLX 80 Casement Window

What is the lead time for the VLX 80 Casement Window?
Typical lead time for the VLX 80 in the San Antonio market is 3 to 6 weeks from order confirmation, depending on glass and finish selections. Custom sizes, laminated glass, and non-standard finishes may add a week or two. We confirm the current factory lead time when we quote your project. Call (903) 488-7019 and we’ll give you today’s number, not a guess.

Does the VLX 80 qualify for energy tax credits?
The thermal break and Low-E glass combination on the VLX 80 can meet the performance thresholds for the federal energy efficiency tax credit on qualifying primary residences. Eligibility depends on your specific glass configuration, the climate zone, and the current tax year rules. We’ll tell you exactly what applies to your project, no games.

What warranty comes with the Casement Window?
ViewLux provides a manufacturer’s warranty on the frame, hardware, and glass, and Juniper Windows San Antonio backs the installation workmanship with our own coverage. The specific warranty terms depend on the product line and installation type, and we’ll provide the written warranty document with your quote, not after you sign.

Can I customize the size?
Yes, the factory produces the VLX 80 to your measurements within the system’s minimum and maximum sash dimensions for casement operation. We confirm your rough openings support the sash size and wind-load requirements before the order goes in, which prevents surprises at install. That pre-check is standard on every project we run.

How do I maintain aluminum frames?
Aluminum frames need very little care. Clean the finish twice a year with mild soap and water, keep the track and hinges free of debris, and lubricate the crank mechanism annually with a dry silicone spray. Avoid abrasive cleaners that can scratch the finish. If you see condensation between the panes in an older sealed unit, that’s a glass failure, not a cleaning issue, and it’s worth a call. Reach us at (903) 488-7019 with any maintenance questions.
