Product Overview – VLX 500 Sliding Window

The VLX 500 is a high-performance aluminum sliding system engineered around one idea: that a window should disappear. The frame profile measures just 1.97 inches wide, which means more glass, more Hill Country light, and cleaner sightlines from every room. It’s available in both 2-track and 3-track configurations, so you can open half the wall or two-thirds of it depending on how much airflow you want and how wide your rough opening runs.

Why do buyers choose this series over standard vinyl sliders? A few reasons. First, the aluminum frame resists the warping and sagging that Austin’s heat cycle dishes out year after year. Second, the glide is effortless. We’ve had clients in Mueller literally push a six-foot panel with two fingers. Third, the customization depth is unusual for this price point. Six finish options, five glass types, retractable or sliding screens. You can build a window that looks like it was specified by an architect without paying architect markups. Westlight Windows Austin carries this series because it fits the way Austin builds now: modern, glass-forward, and serious about performance.

Technical Specifications

Here’s the VLX 500 Sliding Window broken down by the numbers that matter during planning and rough-in:

• Wall thickness: 0.079 inches. That’s a substantial gauge for a residential aluminum window, and it’s part of why these frames hold their square over decades.
• Profile width: 1.97 inches. Slim enough for a clean architectural line, deep enough to support thermal break technology and multi-point locking hardware.
• Track configurations: 2-track and 3-track. Two-track keeps sightlines minimal for standard openings. Three-track gives you a wider clear opening, which works beautifully on patios and living room walls in Austin homes with indoor-outdoor living setups.
• Glass options: Clear, Frosted, Low-E, Tempered, Laminated.
• Finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, Teak Wood.
• Screen options: Retractable Screen, Sliding Screen.

Performance Features

Thermal Efficiency. The VLX 500 includes a thermal break in the frame, which separates the interior and exterior aluminum so heat doesn’t conduct straight through the metal. Combined with Low-E glass, this design earns NFRC-rated energy performance numbers that hold up under Austin’s August sun. Expect lower AC loads and fewer hot spots near window walls.

Acoustic Performance. Aluminum frames paired with laminated glass cut significant exterior noise. We’ve installed the VLX 500 in homes off South Lamar and Burnet Road where traffic hum was a daily annoyance. The sound control ratings on this series make a real difference, especially in bedrooms and home offices.

Airtightness & Weather Seal. Every perimeter joint gets sealed with AAMA 812 low-expansion foam, which means the window blocks air movement at the framing connection, not just at the weatherstripping. That’s a detail many installers skip. We don’t. The result is a quieter, dust-resistant, energy-stable home in Austin’s pollen-heavy spring months.

Waterproofing. The drainage design on the VLX 500 channels water away from the track and out through weep ports engineered into the frame. Proper slope and leveling during installation matter just as much as the window itself, which is why Westlight Windows Austin sets every unit dead level and plumbs every jamb before sealing.

Wind Resistance. Austin gets its share of spring thunderstorm wind and the occasional tornado warning on the outskirts. The VLX 500 is wind-load rated for local climate requirements, and laminated glass adds impact resistance if you want extra protection on exposed elevations or second-story windows.

Security & Hardware. Multi-point locking on the sliding panel means it secures at more than one point along the track. That’s a meaningful upgrade over the single center latch on typical sliders. Tempered or laminated glass adds an additional layer of security for ground-floor windows in neighborhoods around UT and East Austin.

Color & Glass Options

The VLX 500 gives you six finish directions. Premium Black and Anodized Silver lean contemporary and pair well with the black-framed modern builds going up in East Austin and Mueller. Pure White suits traditional and farmhouse elevations, especially in communities like Steiner Ranch and Avery Ranch where white trim still dominates. Bronze and Champagne add warmth without heaviness, and they look sharp against Hill Country limestone and brick. Teak Wood is the wildcard: a wood-look aluminum finish that reads as mid-century modern when used on ranches in Allandale and Crestview.

On glass: Clear is right for maximized views and budget. Frosted works for bathrooms, sidelights, and street-facing rooms where privacy matters. Low-E is our default recommendation for Austin because it blocks UV and solar heat gain. Tempered glass satisfies code requirements near doors and in low windows. Laminated glass adds impact resistance and cuts sound transmission, which is worth the upgrade if you’re near Mopac, I-35, or a busy school zone.

Installation by Westlight Windows Austin in Austin

Here’s the honest truth about window installation: a well-built window installed poorly is a worse investment than an average window installed correctly. The VLX 500 can perform beautifully, but only if the opening is prepped, squared, sealed, and flashed the right way. Westlight Windows Austin installs every VLX 500 according to AAMA 2400 and 2410 standards, which are the accepted national benchmarks for window installation quality.

Our process starts with a pre-install inspection of the rough opening. We check for water damage, framing rot, out-of-square conditions, and insulation gaps before anything gets ordered or set. In Austin, that matters because older homes in neighborhoods like Hyde Park and Travis Heights rarely have perfectly square rough openings after 70 years of settling.

During installation, we set every panel with shims until it’s level, plumb, and square in all three axes. Then we seal every perimeter joint with AAMA 812 low-expansion foam and flash the exterior per manufacturer spec. A final water test verifies drainage and seal performance before we install trim and clean up. Skipping any of these steps voids the manufacturer warranty on the window. We don’t skip steps. That’s the whole reason we exist as an authorized ViewLux installation partner in Austin.
