Product Overview – VLX 500 Single & Double Hung Window

The VLX 500 is what most people picture when they think of a classic American window: two stacked sashes that glide vertically in the frame. It’s a window that works on nearly every architectural style we see in San Antonio, from the Craftsman bungalows in Monte Vista to the stucco ranch homes in Leon Valley and the new builds popping up around Cibolo. The double hung version gives you the flexibility to open the top sash, the bottom sash, or both, which creates a natural convection flow that pulls cooler air in low and lets warm air escape high. That’s not a minor detail in a city where the air conditioner runs for eight months a year.

What sets this series apart from cheaper aluminum windows is the engineering underneath the clean lines. The 0.079-inch wall thickness in the frame gives the window real structural integrity. You feel it when you operate the sash. There’s no flex, no rattle, no sense that the window is barely holding itself together. The tilt-in mechanism uses engineered pivot points that are tested for thousands of cycles, so sashes stay aligned and easy to operate for years. Buyers choose the VLX 500 when they want the low-maintenance, long-life character of aluminum without sacrificing the traditional hung-window look that suits San Antonio’s older neighborhoods.

Technical Specifications

Here’s the VLX 500 Single & Double Hung Window in plain terms, with all the numbers a builder or a detail-oriented homeowner in San Antonio would want to see:

• Frame wall thickness: 0.079 inches, a heavier gauge than standard economy windows, which translates to better rigidity and longer sash alignment
• Overall profile width: 2.36 inches, a compact sightline that maximizes glass area without looking bulky on the exterior
• Glass options: Clear, Frosted, Low-E, Tempered, and Laminated. Each can be spec’d in insulated configurations to meet San Antonio’s energy requirements
• Finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, and Teak Wood
• Screen options: Half-screen, which covers only the lower opening, or full screen for maximum ventilation coverage
• Operation: Single hung has a fixed upper sash and operable lower sash. Double hung gives you independent operation of both sashes with tilt-in cleaning on both
• Thermal performance: Thermal break technology within the frame, rated under NFRC testing standards for energy performance
• Installation compliance: Installed by Juniper Windows San Antonio per AAMA 2400/2410, with AAMA 812 low-expansion foam at all perimeter joints

Performance Features

Thermal Efficiency
San Antonio summers punish a window that can’t hold the line against heat. The VLX 500 uses a thermal break inside the frame that interrupts conductive heat transfer through the aluminum. Paired with Low-E glass, this window keeps the July sun from turning your living room into a hothouse. NFRC-rated performance means you can compare real numbers, not marketing claims.

Acoustic Performance
If you live near Loop 410, I-10, or the railroad corridors that cross San Antonio, you know that street noise is a quality-of-life issue. Laminated glass is the big lever here. The interlayer in laminated glass dampens sound transmission noticeably, and the tight perimeter seal on a professionally installed VLX 500 keeps noise from sneaking in around the frame. We recommend laminated glass for homes on busy streets or near the airport flight paths.

Airtightness & Weather Seal
A window is only as good as the seal around it. We install every VLX 500 with AAMA 812 low-expansion foam at all perimeter joints, which fills the gap between the rough opening and the frame without bowing it. The result is an airtight installation that stops conditioned air from leaking out and outdoor air from leaking in. That’s a month-over-month utility bill difference.

Waterproofing
San Antonio gets monsoon-style downpours in spring and fall, and a window that leaks is a window that fails. The VLX 500’s design channels water away from the glass and sash, routing it down and out through the weep system in the sill. Combined with our AAMA-compliant flashing and perimeter sealing, the window handles driving rain without letting moisture reach your drywall or framing.

Wind Resistance
We’re on the edge of the Texas coastal wind zone, and spring storms can push serious gusts through San Antonio. The heavier wall thickness in the VLX 500 frame and its wind-load rating mean the sash stays put and the frame stays square when the weather turns violent. For homes that need more, impact-resistant laminated glass is available as an option.

Security & Hardware
The locking mechanism on the VLX 500 is integrated into the sash, not bolted on as an afterthought. When locked, the sashes interlock and resist prying. The aluminum frame itself is a deterrent. Add laminated glass and you have a window that’s genuinely hard to breach, which matters for ground-floor windows and street-facing bedrooms in any San Antonio neighborhood.

Color & Glass Options

The VLX 500 comes in six finishes that cover nearly every design language you’ll find in San Antonio. Premium Black is the dominant choice for contemporary and modern-farmhouse exteriors – it frames the glass like a picture frame and hides dirt well. Pure White suits the classic white-trim homes across the Northside and the Hill Country aesthetic. Anodized Silver is honest aluminum, clean and commercial, often used on mid-century modern restorations. Bronze reads warm and works beautifully on Spanish Colonial and Mission-style homes. Champagne is a softer metallic that suits transitional designs. Teak Wood gives you the warmth of wood-grain texture without maintenance, a strong fit for traditional neighborhoods like King William or Olmos Park.

Glass selection in San Antonio usually comes down to energy and sunlight. Low-E is our default recommendation for south and west-facing windows, where the afternoon sun hits hardest. Tempered glass is required for windows near doors, in bathrooms, or where code demands safety glazing. Frosted works for bathrooms and private interior-facing windows. Laminated glass is the upgrade for storm protection and noise reduction, and it holds together if broken instead of shattering into shards.

Installation by Juniper Windows San Antonio in San Antonio

A great window installed badly is a bad window. Careless installation voids factory warranties, lets water into your walls, and creates drafts that undo the energy rating. The VLX 500 is no exception. That’s why we install it properly, every time.

Our process starts with a pre-installation inspection of the rough opening. We check for rot, out-of-square framing, and moisture issues in the wall cavity before we ever set a window. In older San Antonio homes, especially those with original cedar or redwood framing, hidden damage from decades of humidity is common. We find it before it becomes a bigger problem.

Then we set the window level, plumb, and square. We shim and secure it correctly, not just “good enough to pass a glance.” Every perimeter joint is sealed with AAMA 812 low-expansion foam, which insulates and seals without distorting the frame. Flashing and drainage are handled per AAMA 2400/2410 guidelines so water that gets behind the siding has a path out instead of into your sheathing. After the install, we run a water test on the sill and perimeter, clean up the worksite, and walk you through operation and glass care.

San Antonio’s climate makes correct sealing especially critical. We get long dry spells followed by heavy rain, and that wet-dry cycle causes expansion and contraction in every building material. A window installed tight and sealed correctly handles that cycle without leaking. A rushed install doesn’t.

Frequently Asked Questions – VLX 500 Single & Double Hung Window

What is the lead time for the VLX 500 Single & Double Hung Window?

Most VLX 500 orders in San Antonio are delivered and ready for installation within 3 to 6 weeks from the date the order is finalized, depending on glass type, finish, and size. Custom sizes and laminated glass can add time. Call (903) 488-7019 and we’ll give you a realistic timeline for your specific configuration after a site measurement.

Does the VLX 500 qualify for energy tax credits or local rebates in San Antonio?

The VLX 500 can qualify for federal energy tax credits when ordered with qualifying Low-E glass and the proper NFRC performance ratings. CPS Energy has also offered residential rebate programs for qualifying energy-efficient window replacements, and eligibility depends on the current program year and your home’s specifics. We’ll document your window’s performance ratings so you can file with confidence. Call (903) 488-7019 to get a quote with energy-rated glass pricing.

What warranty coverage comes with the VLX 500 Single & Double Hung Window?

ViewLux provides a manufacturer’s warranty on the VLX 500 covering the frame, glass, and hardware against defects in materials and workmanship. The installation workmanship by Juniper Windows San Antonio is covered by our own workmanship warranty. The key thing to understand: the manufacturer’s warranty applies only when the window is installed by an authorized partner using AAMA-compliant installation methods. We are an authorized ViewLux installation partner, so your warranty stays intact.

Can I get custom sizes, or is the VLX 500 only available in stock dimensions?

The VLX 500 Single & Double Hung Window is available in custom sizes sized to your rough openings. We don’t resize your opening to fit a generic window. We measure each opening precisely and order the window to fit, which means cleaner sightlines, better sealing, and no oversized trim hiding gaps. That’s how a replacement window should fit in a San Antonio home with non-standard framing.

How do I maintain aluminum frames in San Antonio’s climate?

Aluminum frames, especially with a durable factory finish like the VLX 500’s, require almost no maintenance beyond a twice-yearly cleaning with mild soap and water. Wipe down the tracks and keep the weep holes clear of dust and pollen. Inspect the perimeter caulk once a year, since San Antonio’s heat and UV exposure will eventually age any exterior sealant. If you spot cracking or separation, call us at (903) 488-7019 and we’ll re-seal before water becomes a wall problem.
