Product Overview – VLX 500 Sliding Window

The VLX 500 is ViewLux’s high-performance aluminum sliding system, and it solves a specific problem: how to get a wide, uninterrupted view without the bulk and sag that plague lesser aluminum windows. The profile is genuinely slim at 1.97 inches, which reads almost frameless from inside the house. The wall thickness runs 0.079 inches, giving the extrusion enough structural stiffness to hold large glass units without flexing under wind load. That matters in San Antonio, where spring storms roll through with real force and a flimsy frame will let you feel every gust.

Buyers choose this series for two reasons. First, the glide. The sashes ride on precision rollers engineered to move with one hand, even on a six-foot panel. Second, the configuration flexibility. You can spec the VLX 500 as a 2-track or 3-track system, meaning two movable sashes or a three-panel arrangement that opens up two-thirds of the opening. That 3-track option is popular in San Antonio kitchens and sunrooms where ventilation matters as much as the view. Lightwell Windows San Antonio has supplied and installed the VLX 500 in neighborhoods from King William to Boerne, and the feedback is consistent: it operates like a window that cost twice as much.

Technical Specifications

Every VLX 500 we order is built to the opening measurements we take on site, not to a “close enough” standard size. That’s how the system was designed to be sold, and it’s how Lightwell Windows San Antonio installs it across San Antonio.

Performance Features

Thermal Efficiency The VLX 500 uses a thermal break in the aluminum extrusion, separating the interior and exterior metal faces so heat doesn’t conduct straight through the frame. Combined with Low-E glass, this system earns NFRC-rated energy performance numbers that matter on San Antonio’s 95-degree August afternoons and the occasional hard freeze in January.

Acoustic Performance Aluminum is not known for quiet, but this system is different. The 0.079-inch wall thickness plus tight gasketing keeps the sashes seated firmly against the frame, reducing rattle and cutting road noise. Laminated glass takes it further. If you live near Loop 410, I-10, or any busy San Antonio corridor, laminating is worth the upcharge.

Airtightness & Weather Seal The VLX 500 is engineered for airtightness, with continuous gaskets along the sash perimeter and interlocking meeting rails that seal when the panel closes. No dusty drafts, no whistling during a north wind. Lightwell Windows San Antonio installs every unit with AAMA 812 low-expansion foam sealant on all perimeter joints, which keeps air from sneaking around the frame itself.

Waterproofing The track system includes integrated drainage channels that direct water out and away from the sill. That’s critical in San Antonio, where a single thunderstorm can drop an inch of rain in thirty minutes. Our AAMA 2400/2410 installation process includes correct sill flashing and weep alignment, so water exits the window the way the manufacturer intended.

Wind Resistance The VLX 500 is wind-load rated for the conditions San Antonio actually experiences, including spring storm fronts and the occasional hurricane remnant that reaches Bexar County. The 0.079-inch extrusion thickness gives the frame the rigidity to hold large panes without visible flex. Impact-resistant laminated glass is an option for homeowners who want maximum protection.

Security & Hardware The locking hardware on the VLX 500 engages at multiple points along the meeting rail, not just a single center latch. The extruded aluminum frame and tempered or laminated glass options make forced entry significantly harder than a wood or vinyl window. It’s a quiet security upgrade few San Antonio homeowners think about until they see the hardware up close.

Color & Glass Options

The VLX 500 comes in six finishes. Premium Black and Pure White are the most requested in San Antonio’s newer builds, especially in modern and contemporary homes where the dark frame against stucco or white against brick creates clean contrast. Anodized Silver suits mid-century and ranch-style houses, holding up well without paint that can fade. Bronze and Champagne read warm and subtle, a good match for homes with earth-tone exteriors or Tuscan-style architecture found in parts of North San Antonio. Teak Wood is a woodgrain finish for homeowners who want the look of wood without the maintenance, popular in traditional neighborhoods like Terrell Hills and Olmos Park.

Glass selection depends on what the window faces. Clear glass is the budget pick. Frosted works for bathrooms and side yards where privacy trumps view. Low-E is the smart default in San Antonio, cutting solar heat gain during the long cooling season. Tempered glass meets code for windows near doors and low sills, and laminated glass adds both impact resistance and noise reduction. We’ll walk you through which combination makes sense for each opening.

Installation by Lightwell Windows San Antonio in San Antonio

Here’s what happens when you buy a VLX 500 from Lightwell Windows San Antonio. First, we come to your home and measure every opening. Not a rough guess. An exact measurement with notes on the condition of the existing frame, the wall depth, and any water damage or settling issues around the opening. If there’s rot or a structural problem, we tell you before we order anything so there are no surprises mid-install.

When the windows arrive, our installers set every unit level, plumb, and square. That is not a slogan. A sliding window that is even slightly out of level will bind, drag, or leak. We check each panel before it leaves the shop and again after it’s set in the opening. Perimeter joints are sealed with AAMA 812 low-expansion foam, which fills gaps without distorting the frame. Flashing is installed to AAMA 2400/2410 standards, which is the recognized installation standard for window performance. After installation, we run a water test on the sill and track and walk the homeowner through operation and maintenance.

One thing homeowners in San Antonio should know: a window installation mistake voids the manufacturer warranty. ViewLux warranties the product, but an improper install by an unqualified contractor means the manufacturer walks away and you’re left holding the repair bill. Lightwell Windows San Antonio installs to the standard the warranty requires, and we stand behind our workmanship separately. Given San Antonio’s heat, humidity swings, and storm patterns, professional installation is not an optional line item.

Frequently Asked Questions – VLX 500 Sliding Window

What is the lead time for the VLX 500 Sliding Window? Most VLX 500 orders through Lightwell Windows San Antonio take three to five weeks from final measurement to delivery at your home. Custom finishes and laminated glass can add up to two weeks. We give you a firm date when you place the order, not a vague range. Call (325) 420-4173 and we’ll check current production times for your configuration.

Does the VLX 500 qualify for energy tax credits? The VLX 500 with Low-E glass meets the energy performance requirements for the federal windows and skylights tax credit in most installations. Eligibility depends on the specific glass package and the climate zone, which for San Antonio is Zone 2. We’ll provide the NFRC performance documentation you need for your tax filing. Call (325) 420-4173 for the details on your specific order.

What warranty comes with the Sliding Window? The VLX 500 carries the manufacturer’s warranty from ViewLux, covering the frame, hardware, and glass. Labor is covered by Lightwell Windows San Antonio’s workmanship warranty on installation. The important caveat: the manufacturer warranty is void if the window is installed incorrectly. That’s a major reason San Antonio homeowners buy through us rather than hiring a handyman.

Can I customize the size? Yes. Every VLX 500 is ordered to the exact opening dimensions we measure at your San Antonio home. The 2-track and 3-track configurations accommodate a wide range of widths and heights, including oversized openings that stock windows at big-box stores won’t cover. We’ll confirm the maximum and minimum dimensions for your chosen configuration at the free measurement appointment.

How do I maintain aluminum frames? Wipe the frames down with mild soap and water twice a year, and clean the track with a vacuum and damp cloth. San Antonio dust and oak pollen collect in window tracks faster than you’d expect. Lubricate the rollers annually with a silicone spray. The powder-coated finishes do not require painting. For anything beyond routine cleaning, call (325) 420-4173 and we’ll advise you before you touch the hardware.
