VLX 80 Casement Window

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

The VLX 80 Casement Window is a side-hinged aluminum window built around one core idea: frame as little of your view as possible while letting in as much air as the opening allows. In San Antonio, where afternoon heat pushes homeowners toward maximum cross-ventilation and long sightlines to the Hill Country matter, this window earns its place. Lightwell Windows San Antonio is an authorized ViewLux installation partner, which means we sell, measure, install, and service this product under one roof and one warranty. No third-party handoff. No finger-pointing if something goes sideways. Call (325) 420-4173 to talk through your project or book a free measurement.

Product Overview – VLX 80 Casement Window

The VLX 80 is what architects reach for when a window has to disappear. The frame profile measures just 1.97 inches across, which is remarkably slim for an aluminum system carrying a reinforced wall thickness of 0.079 inches. In practice, that means the glass dominates the opening, not the frame. Casement operation puts the sash on side hinges, so the entire pane swings outward like a door, capturing breeze from directions a sliding or double-hung window simply cannot. For San Antonio homes, this matters. A casement window facing the prevailing southeast wind will pull air through the house on days when you’d rather not run the AC around the clock.

Buyers in Alamo Heights, Stone Oak, Terrell Hills, and the King William district choose this series because it fits both mid-century ranch remodels and new builds with a modern, minimal language. The aluminum resists the kind of thermal expansion and warping that vinyl frames develop after enough Texas summers. And because Lightwell Windows San Antonio installs the VLX 80 to AAMA 2400/2410 standards in San Antonio, the performance you pay for on paper is the performance you actually get once the window is set, sealed, and tested.

Performance Features

Thermal Efficiency

The VLX 80 uses a thermal break built into the aluminum frame, separating the exterior and interior metal faces. That break is what stops San Antonio’s August heat from conducting straight through the frame into your living room. With Low-E glass in the sash, the system delivers NFRC-rated energy performance that holds up under direct Texas sun. Lower cooling loads, steadier indoor temperature.

Acoustic Performance

San Antonio’s growth means more traffic on Loop 1604, I-10, and 281 than ever. Laminated glass in the VLX 80 adds a sound-dampening interlayer that reduces the kind of road noise that leaks through standard insulated units. Pair laminated glass with the casement’s compression seal and the difference is noticeable the first night you close the window.

Airtightness & Weather Seal

Casement windows seal on compression. The sash presses against the weatherstripping around all four edges when locked, which is inherently tighter than the sliding contact of a double-hung or slider. The VLX 80 is engineered for high airtightness performance, and we install it with AAMA 812 low-expansion foam sealed around every perimeter joint. No draft gaps. No whistling on windy March days.

Waterproofing

San Antonio’s flash floods and spring downpours drive rain sideways. The VLX 80’s drainage design channels water that gets past the exterior seal toward the weep system instead of into the wall cavity. Combined with the level and plumb installation we perform at Lightwell Windows San Antonio, the waterproofing rating on this window means dry drywall and intact framing, even in a Hill Country blow.

Wind Resistance

South Texas storms bring serious gusts, and the VLX 80 is wind-load rated for the local climate. The 0.079-inch wall thickness resists flex under pressure, keeping the sash tight against the seal when the wind pushes hard. If you’re in a higher-exposure area near the Medina River valley or out toward Boerne, ask us about laminated impact glass for added resistance to windborne debris.

Security & Hardware

The locking mechanism on a casement window is not an afterthought. Multi-point locking hardware engages at more than one point along the sash, making forced entry considerably harder than a single center latch. The aluminum frame itself provides structural stiffness that no vinyl extrusion can match. If security matters in your San Antonio neighborhood, this is a strong reason to choose the VLX 80.

Color & Glass Options

The VLX 80 comes in six finishes. Premium Black is the most requested finish in San Antonio’s newer modern builds and black-frame farmhouse remodels, where contrast against white stucco or light brick makes the window read as architectural intent. Pure White and Anodized Silver fit traditional limestone and painted brick homes. Bronze and Champagne suit warmer palettes, sandstone exteriors, and homes with wood or tile accents. Teak Wood offers a wood-look finish for homeowners who want the warmth of timber without the maintenance load in San Antonio’s UV and humidity profile.

On glass, Clear is the budget baseline. Frosted works for bathrooms and side entries where light matters but privacy matters more. Low-E is the workhorse for San Antonio, reflecting solar heat while allowing daylight. Tempered glass is safety-rated for larger panes and impact zones where building codes require it. Laminated glass upgrades you to impact resistance and meaningful sound reduction. We’ll match the right glass spec to the orientation of each wall and the specific demands of your San Antonio home.

Installation by Lightwell Windows San Antonio in San Antonio

Even the best-engineered window fails if it goes in wrong. That is not a sales line. The VLX 80 carries a manufacturer warranty, and ViewLux’s warranty assumes proper installation to AAMA standards. An improperly flashed, out-of-plumb, or under-sealed install gives you air leakage, water intrusion, and a warranty dispute you won’t win.

Our installation crew pre-inspects every opening before the window goes in. We check the rough opening, the framing condition, and the existing waterproofing layer. Then the window goes in level, plumb, and square, anchored to carry the load and survive San Antonio’s expansion-and-contraction cycle season after season. Every perimeter joint receives AAMA 812 low-expansion foam sealant. Flashing follows the AAMA 2400/2410 installation standard. Then we run a final water test and walk the interior with you before cleanup starts. The truck leaves, but our workmanship stays. That’s the difference between someone who sells windows and an authorized partner who installs them in San Antonio every week.
