Product Overview – VLX 500 Single & Double Hung Window

The VLX 500 hangs on a classic formula that San Antonio has always liked: two sashes that glide vertically, with the top sash dropping down and the bottom lifting up. That dual-ventilation design moves air through a room more efficiently than a fixed window or casement, which matters when July hits and you want cross-breeze before the AC kicks on. The single hung version keeps the top sash fixed, which costs less and still delivers the same clean look. The double hung gives you both operable sashes plus the convenience of tilting them inward for cleaning without a ladder.

What sets this series apart is the aluminum frame. Aluminum doesn’t warp in San Antonio’s heat the way vinyl can after years of direct sun, and it holds its shape in the humidity swings we get from spring storms. The tilt-in function is a genuine quality-of-life feature, not a gimmick: pop the latches, tip the sash down, wipe the glass from your living room. Buyers in neighborhoods like Alamo Heights, Stone Oak, and Terrell Hills choose the VLX 500 when they’re replacing wood windows that have rotted or vinyl windows that have sagged, and they want something that looks sharp without demanding constant upkeep.

The profile width is 2.36 inches, which gives the frame enough presence to read as substantial on a larger elevation, while still maximizing glass area compared to bulkier clad wood frames. The wall thickness measures 0.079 inches, a heavier extrusion than bargain aluminum windows, and that extra material translates to less flex when the wind loads hit during storm season.

Technical Specifications

Lightwell Windows San Antonio orders every VLX 500 size-to-open and configures the glass, finish, and screen package per project. There’s no stock sizing that forces you into a fix-and-forget fit.

Performance Features

Thermal Efficiency – The VLX 500 uses a thermal break inside the frame, separating the interior and exterior aluminum so heat doesn’t conduct straight through the metal. That’s the difference between an old builder-grade aluminum window that sweats in winter and a modern NFRC-rated system that contributes to your home’s overall energy performance. Low-E glass options add a second layer of heat rejection for west-facing bedrooms in San Antonio.

Acoustic Performance – If you live near Loop 410, I-10, or under a flight path, you already know road and air noise finds its way through weak windows. The VLX 500’s frame sealing paired with laminated glass delivers measurable sound reduction. Laminated glass adds an interlayer that dampens vibration, and it’s the upgrade we recommend most in neighborhoods like Jefferson and Monticello Park where street noise is a daily reality.

Airtightness & Weather Seal – Every VLX 500 we install in San Antonio gets an AAMA 812 low-expansion foam sealant on all perimeter joints. That’s the standard we hold ourselves to because it stops air infiltration at the rough opening, not just at the sash. A window can test well in a lab and leak in your wall if the perimeter isn’t sealed correctly. We seal every joint, every time.

Waterproofing – San Antonio’s spring downpours and fall storms don’t give a poorly flashed window a pass. The VLX 500 is engineered with drainage channels that direct water away from the interior, and our installation under AAMA 2400/2410 includes proper sill flashing and back-dam details. The combination of factory design and field-correct flashing is what keeps water on the outside where it belongs.

Wind Resistance – Texas wind codes are not suggestions. The VLX 500 is wind-load rated and, with the 0.079-inch wall thickness, holds its shape under load better than thinner aluminum systems. For homes on the hill country’s edge or in exposed subdivisions without mature tree cover, the added rigidity matters.

Security & Hardware – The VLX 500 comes with sash locks designed to resist forced entry from outside, and the aluminum frame can’t be flexed open the way a vinyl frame sometimes can. Laminated glass adds a security advantage: it’s impact-rated and doesn’t shatter into sharp shards, which is why we suggest it for ground-floor windows in any San Antonio neighborhood.

Color & Glass Options

The VLX 500 comes in six finish options, and the right choice depends on your home’s style. Premium Black is the go-to for the modern farmhouse and contemporary builds popping up around San Antonio’s north side; it creates a strong contrast against white stucco or brick. Pure White stays classic and works on traditional Hill Country homes and brick ranches. Anodized Silver reads as clean and commercial-leaning, ideal for mid-century or contemporary styles. Bronze suits Spanish and Mediterranean elevations like the ones throughout Olmos Park and Monte Vista. Champagne is a warmer metallic that pairs well with limestone and beige stonework. Teak Wood gives you a wood-look finish on an aluminum frame, so you keep the maintenance-free behavior without losing that warm traditional feel.

On the glass side: Clear is the baseline. Frosted adds privacy for bathrooms and side lights. Low-E cuts solar heat gain, which is the single best glass upgrade for San Antonio’s climate. Tempered is safety glass that meets code for windows near doors and low sill heights. Laminated delivers impact resistance and noise reduction. Many clients combine Low-E with laminated for bedrooms facing the street or the afternoon sun. Call (325) 420-4173 and we’ll help you pick the right combination for each room.

Installation by Lightwell Windows San Antonio in San Antonio

A window is only as good as the hand that puts it in. We regularly see failed window projects across San Antonio where the product was fine and the installation wasn’t: gaps behind the trim, missing flashing, foam that was never shaved or sealed. An improperly installed window voids the manufacturer warranty, and that’s the part most homeowners don’t learn until water is already in the wall.

Our team starts with a pre-install inspection of every opening. We’re checking the rough opening dimensions, looking for existing rot or water damage, and confirming the framing is square enough to receive the window correctly. If there’s rot, we tell you before we install, not after. Then we set the window level, plumb, and square, shimming precisely so the sash glides smoothly and the locks engage properly from day one.

On every perimeter joint we use AAMA 812 low-expansion foam sealant. Low expansion is the key: standard expanding foam pushes against the frame and can bow the jambs, which makes the window bind. After the foam cures, we run a continuous sealant bead at the exterior perimeter, flash the sill and head correctly per AAMA 2400/2410, and finish with a final water test on ground installations. Cleanup is included; we haul the old sashes and debris off your property.

San Antonio’s clay-heavy soil means homes settle over time, and older openings are rarely perfectly square. We account for that during the rough-opening prep and shimming instead of forcing a window into an opening it doesn’t fit. For homes in older neighborhoods like Alta Vista and King William, this step matters even more. We pull permits when the project requires them, and every installation is warranty-safe because it’s done to the manufacturer’s install spec. It’s not the fastest way to put a window in; it’s the right way.

Frequently Asked Questions – VLX 500 Single & Double Hung Window

What is the lead time for the VLX 500 Single & Double Hung Window? Lead time for the VLX 500 is typically 3 to 6 weeks from order to delivery at our San Antonio warehouse, depending on glass and finish configuration. Custom sizes don’t add much time since the windows are made to order anyway, but laminated and Low-E combinations can sit on the longer end. We confirm a delivery window when you approve the quote and tell you the installation date before we order anything.

Does the VLX 500 qualify for energy tax credits? The VLX 500 may qualify for federal energy efficiency incentives when configured with the right Low-E glass package, but eligibility varies by tax year and your specific home project. The frame carries NFRC-certified thermal ratings, so we can provide the performance data your CPA or tax preparer needs. We suggest confirming current incentives with your tax professional, and we’ll supply the spec sheets at no charge.

What warranty comes with the Single & Double Hung Window? The VLX 500 is covered by ViewLux’s manufacturer warranty, and your protection as a San Antonio homeowner depends on the install being performed by an authorized partner using the specified methods. Lightwell Windows San Antonio is an authorized ViewLux installation partner, which keeps your warranty intact and gives you one point of contact for service down the road. We walk you through the warranty terms before you sign anything.

Can I customize the size? Yes, the VLX 500 is made to order, so you’re not stuck with stock sizing from a big-box aisle. We field-measure every opening ourselves and order the exact size needed, which matters in San Antonio homes where 40-year-old rough openings have drifted out of square. If you’re replacing an odd-sized wood window, we can match the dimensions close enough that your interior trim stays put.

How do I maintain aluminum frames? Aluminum frames need almost nothing from you: soap and water a few times a year keeps the finish looking new, and the moving parts like the tilt latches and sash locks want a light silicone spray annually. The beauty of aluminum versus wood is that you’ll never sand, repaint, or caulk a rotting sill again. If a sash ever needs adjustment years down the road, call us at (325) 420-4173 and we’ll come out.
